sample

<Text View
    android:text="Hapy Birthday"
    android:layout_width="150dp"
    android:layout_height="150"
    android:background="@android:color/darker_groy"
    >

The height has no unit of "dp"
color specification is wrong.
there is no closing tag written properly.
There is space between the Text and the View ,there should not be any space.

A altura não tem nenhuma unidade de "dp"
especificação de cor é errada.
não há nenhuma marca de fechamento escrito corretamente.
Há um espaço entre o texto e o View, não deve haver qualquer espaço.

XML element name should be TextView
XML tag should be closed with a forward slash
layout_height attribute should be "150dp"
background attribute should be "@android:color/darker_gray"

Lets see there is no forward slash to make it a self closing tag including there is no dp by the layout_height attribute, there should be no space between Text and View also the "happy" could be spelled correct lol!!!

1- TextView instead of Text View
2- android:layout_height="150dp" instead of android:layout_height="150"
3- android:background="@android:color/darker_gray" instead of android:background="@android:color/darker_groy"
4- closing the tag />
5- Happy instead of hapy but it will not affect the code

1- Debería ser TextView
2- falto "dp" en el android:layout_height="150"
3-"darker_groy" no es un color valido
4-No esta cerrando el TextView, falta el "/"

line1-does not follow camelCase
line2-incorrect grammar
line3-"150dp"
line5-darker_gray
line6- />

Line 1 should be <TextView
Line 4 should be "150dp"
Line 5 should be "/darker_gray"
Line 6 should be />

TextView has a space
layout_height missed "dp"
spelling mistake in "darker_gray"
closing tag is not written properly.

line 1 Not camelcase
line 3 missing dp
color name grey
there is no closing tag written properly.

1 line - TextView, not Text View
4 line - missing "dp" after 150
5 line - darker_gray, not darker_groy
6 line - missing / before >

They keep telling me to try again :|

missing dp in line 4
missing / closing tag in line 6
wrong color name in line 5
misspelling in TextView in line 1

Text View would be TextView
android:layout_height="150" is faulting the "dp"
darker_groy would be darker_gray
Is faulting /> in the end

1. Space between the name of the view
2. there is no forward slash
3. there is no dp keyword for layout_height
4. the closing tag is in the next line without the name of the view
5. The darker_gory is to as darker_gray

1. use TextView instead Text View, remove the space between.
2. missing dp in layout_height="150", use layout_height="150dp"
3. change "darker_groy" to "darker_grey"
4. closing the tag />

• the dp unit is missing for the attributte "android:layout_height".
• the single line ending tag not containing '/' before closing tag '>'.
• there is a space between the XML tag element "TextView".
• the spelling of gray is wrong for the value in attribute "android:background".

TextView is written wrong as Text View,
android:layout_height = "150dp",
color should be darker_grey,
closing Tag should be />
Hapy Birthday can be Happy BirthDay

Text view should be together as TextView
The height has no unit of "dp"
color should be darker_grey
closing Tag should be />

1 - TextView
2 - Happy Birthday
3 - "150dp"
4 - ".../darker_grey"
5 - />

dp is missed for android:layout_height
darker_gray color is misspelled for background
slash is missed for closing tag
Text View should not have space in the middle

Text View has a space, must be camel case
android:layout_height does not a dp
Spelling of groy must be gr__a__y
No closing / (*claquk) at the end; before closing angle bracket

1. <Text View Tag should have been <TextView
2. Spelling mistake in line android:text="Hapy Birthday" --- Hapy should be changed to Happy
3. android:layout_height="150" --- unit dp missing while specifying layout_height
4. android:background="@android:color/darker_groy" -- color should have been darker_gray
5. The end tag is not closed properly.

In line 1 Camel Case is violated
In line 2 there is some grammar mistake
In line 4 dp is missing
in line 5 groy->gray

The TextView is separated
The height does not have " dp " meaning pixels
the color is misspelled .
missing closing tag / >

The height has no unit of "dp"
color specification is wrong.
there is no closing tag written properly.
There is space between the Text and the View ,there should not be any space.

1- El texto correcto es TextView
2- Faltó especificar la medida de tamaño "dp" en el android:layout_height="150"
3- Está mal escrito el nombre del color "darker_groy" no es un color valido
4- No esta cerrando el TextView, falta el "/". Es esencial en el lenguaje XML

1- TextView
2- dp
3. />
4- gray

the TextView is separated
there is no dp attached to the height
the spell of gray is incorrect
the code need to be closed

• no closing tag
• invalid color value
• no dimension for layout_height
• tag name is incorrect

Code tag Text View must not have a sepace between words
The height value does not have " dp " meaning resolution independent pixels
the color value "groy" is misspelled
Closing tag of the code "/" is missing

Line 1 not CamelCase
Line 2 Although will not give error, best practice no spelling errors "Happy"
Line 4 add "...dp"
Line 5 correct groy to "...gray"
Line close the tag with />

1. Space
2. DP
3. Groy to grey
4. Close tag

• TextView is written incorrectly
• Spelling of Happy is incorrect (which syntactically is ok).
• dp not used for height
• In color attribute it should be gray not groy
• TextView not closed correctly.

Spelling mistake of Happy word.
layout_height is missing dp suffix.
darker_groy has a spelling mistake.
There is no closing tag.

1. TextView had space
2. android:layout_height attribute value had unit (dp) missing
3. android:background attribute had an invalid value (darker_groy)
4. Self-closing tag was missing

1. opening tag TextView should not be any space
2. layout_height size don't have "dp" unit
3. self-closing tag should have "/" before ">"
4. darker_groy is incorrect instead with darker_gray

height missing dp
TextView missing correct closing tag
color darker_groy is incorrect
TextView tag is written incorrectly

This is correct:

=> TextView
=> android:layout_height="150dp"
=> android:background="@android:color/darker_gray"
=> /> at the end line

The XML element name should be "TextView";
The XML should be closed with a forward slash "/>";
The attribute name "layout_height" should be "150dp";
The attribute name "android:background" should "@android:color/darker_gray".

XML element incorrectly written - not following camelcase - "TextView"
The attribute value should be "150dp"
The attribute value should mentioned correct color name - "darker_gray"
The XML element should end with a slash "/>"

XML element should be TextView
The attribute value should be 150dp
The name of color should be darker_gray
The xml element should end with />

Errors:

1. Text Viev instead of TextView
2. Incorrect value in android:layout_height. It should be 150dp insted od 150
3. Incorrect color name. It should be "@android:color/darker_gray"
4. There is no "/>" at the end of the code block. We might find there only ">"

Line 1: Tag Text is not a supported opening tag.
The attribute android:layout_height does not support the value 150
The color @android:color/darker_groy is not supported
The tag TextView should be self-closing. This means it should end with />

No space in TextView, you must place the unit of measurement dp in your android:layout_height=“150dp”, and you mispelled grey for groy

• Line 1: Text View should be TextView
• Line 4: 150 should be 150dp
• Line 5: darker_groy should be darker_gray
• Line 6: > should be />

• The name of the tag should be TextView instead of Text View (there should be no space between a tag name)
• The unit for the android:layout_height is missing. 150dp should be specified as the value for android:layout_height
• The color value is not defined. It should be darker_gray instead of darker_groy
• The tag should be closed as /> instead of >

• Should be TextView instead of Text View
• The TextView tag is not closed
• Groy should be gray
• Layout_height needs dp units

1. the xml element TextView was not had a space in it.
2. The element was not self closed
3. The layout_height attribute value does not have a unit like dp or px
4. darker_groy color is not a recognized color by android

Line 1 : Text View -> TextView
Line 4 : "150" -> "150dp"
Line 5 : "@android:color/darker_groy"-> "@android:color/darker/gray"
line 6 : > -> />

The View should not spaced.
The height has no unit of "dp"
color specification is wrong.
there is no closing tag written properly

Space between Text and View
Hapy is Happy
Missing dp
darker_groy is darker_gray
Missing / at closing tag

Space between Text and View is wrong
groy should be gray
dp is missing in layout_height attribute value
"/" is missing from the closing bracket

Line 1: should be TextView
Line 4: 150dp
Line 5: dark_gray
Line 6: needs closing "/"

The name of the tag should be TextView instead of Text View (there should be no space between a tag name)
The unit for the android:layout_height is missing. 150dp should be specified as the value for android:layout_height
The color value is not defined. It should be darker_gray instead of darker_groy
The tag should be closed as /> instead of >

No space in between Text and View(TextView)
No specification of dp (150dp) in width attribute
Spelling mistake while specifying color (groy-gray)
Missing slash(/) at end of TextView

Space between Text & View should not be there
Missing closing slash for TextView
Missing units for layout width
Typo in color

there should be no space between "Text" and "View".
forward slash missing before ">" sign
Its gray not groy.

space between Text and View : should be TextView
layout_height should be in dp
background color name is not correct : should be darker_gray
closing tag is wrong should be />

Line 4, value doesn't specify dp
Line 6, it need />
Line 1, it should use CamelCase text
Line 5, the correct value is "@android:color/darker_gray"

1. No Camel Case
2. tag is not closed. Missing /
3. misspelled color gray
4. Height is not defined in terms of dp

1. space in XML tag
2. tag is not closed
3. mispelled color gray
4. height doesn't have the units (dp)

no forward slash at the end,
darker_gray - o instead of a
TextView should not have space
height do not have dp as unit for attribute value

1. The name of the Element should be TextView without space
2. Value of attribute android:layout_height should be use "dp"
3. Value of android:background should be darker_gray
4. The self enclosing tag should />

1.Element name should be TextView
2.android:layout_height the value should be"150dp"
3.The value of android:background should be "@android:color/darker_gray"
4.self enclosing tag need forward slash(/)

Text View -> TextView
android:layout_height="150" -> android:layout_height="150dp"
android:background="@android:color/darker_groy" -> android:background="@android:color/darker_gray"

TextView should not have any space
Height value should have dp suffixed
Background color to be darker_gray
End of xml element to have forward slash before >

1.tag Text View supposed TextView
4.nilai of layout should 150dp width attribute (to be given dp)
5.nilai of attributes darker_gray background should not darker_groy
6. The closing tag ">" should "/>"

The correct code is:

<TextView
    android:text="Hapy Birthday"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:background="@android:color/darker_gray"
/>

1.The tag is not closed
2.Height was not given dp
3.The color is not supported by android
4.TextView is not in CamelCase

1. Text View must be TextView
2. missing forward slash in the self closing tag
3. gray not groy
4. missing the unit of measurement of layout_height which is dp

The correct answer:

<TextView
android:text="Happy Birthday"
android:layout_width="150dp"
android:layout_height="150dp"
android:background="@android:color/darker_gray"/>

1. There should be no space between "Text" and "View".
2. "Happy" in "Happy Birthday" is not written correctly.
3. The self-closing backslash is missing.
4. "dp" is not mentioned by the numeric value in layout_height.
5. The spelling of gray is incorrect.

<Text View
android:text="Hapy Birthday"
android:layout_width="150dp"
android:layout_height="150"
android:background="@android:color/darker_groy"

Naming convention of view is violated:it should be in camlecase:like TextView
The value of attribute height is wrong given:it should be 150dp
The value of background color should be :darker_gray
Last the XML closing trag is to be corrected with />

Should i leave here a comment to pass a quiz or what ?

1. TextView in CamelCase
2. For the View to be self-closing, /> should be used at the end.
3. Height should be in dp that is density pixels
4. Incorrect spelling. It should be darker_gray.
   

Espaço entre o TextView,
está faltando uma barra no final do fechamento do código,
faltando dp na linha 3,
darker_gray escrito incorretamente

O correto seria:

<TextView
android:text="Happy Birthday"
android:layout_width="150dp"
android:layout_height="150dp"
android:background="@android:color/darker_gray"
/>

TextView
Happy
150dp in layout_height
darker_gray instead of darker_groy
the closing />

Line 1 TextView has a space
Line 4 layout_height missed "dp"
Line 5 spelling mistake in color name "darker/gray"
Line 6 there is no closing tag written properly />

*TextView
*dp

• />
  *gray

space between "Text and View",Missing "dp" after "layout_height="150",incorrect spelling gray, missing slash in the end, incorrect spelling happy.

1. The View is not in Camel Case
2. The attribute layout_height has no unit of "dp"
3. No slash at line 6. it isnt close tag
4. The value in attribute background is mispelled
   Though not compulsary, the text value, "Happy birthday" is mispelled to

attribute name should be camel case.
layout height should be with correct units
color gray spelling should be change
command ends with closing tag

• View name does not follow camel case.
• Wrongly spelt backgroung color : 'groy'.
• Didn't mention units for layout_height.
• Closing of the tag is not done. If it is a self closing tag then '/>' in the last line. If you want to keep a seperate closing tag then ''.

The following errors are present:
Line 1 : <Text View -> It should be <TextView
Line 4: android:layout_height="150" It should be android:layout_height="150dp"
Line 5 android:background="@android:color/darker_groy" It should be android:background="@android:color/darker_gray"
Line 6: > It should be />

correct code

<TextView
    android:text="Hapy Birthday"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:background="@android:color/darker_gray"/>

The Correct Code

<TextView
    android:text="Hapy Birthday"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:background="@android:color/darker_grey"
    />

Mistakes in Original Code
Text View => TextView (no space)
layout_height no dp was missing
background color shoud be grey not groy
and / was missing in the closing tag ( This is self closing tag)

in line 1 there is space b/w Text and View
in line 4 the value has no unit eg:"dp"
in line 5 the spelling of darker_gray is wrog
in line 6 the is no backslash to close the tag

the correct code is

this is correct or not???

The height has no unit of "dp"
Color specification is wrong.
There is no closing tag written properly.
There is space between the Text and the View. It should be in camel case.

on line 1:- TextView, not Text View
on line 4:- missing "dp" after 150
on line 5:- darker_gray, not darker_groy
on line 6:- missing / before >

line 1 does not follow camel case+ it should be TextView not Text View
line 4: the attribute value doe not have the unit dp
line 5: the attribute value is not present in the library, it should be @android:color/darker_gray
line : does not have / before >

line 1 does not follow camel case+ it should be TextView not Text View
line 4: the attribute value doe not have the unit dp
line 5: the attribute value is not present in the library, it should be @android:color/darker_gray
line : does not have / before >

XML element is not in camel case
attribute-> android:layout_height does not have dp as units
line 6 does not have / before
spelling of gray is wrongly written as groy

line 1 does not follow camel case, it should be TextView not Text View
line 4: the attribute value do not have the unit dp
line 5: the attribute value is not present in the library, it should be @android:color/darker_gray not @android:color/darker_groy
line 6: does not have / before > end of view

TextView is incorrectly writen because it has a space in between the words. There is a "dp" lacking in the value of "android:layout_height". The color specification "darker_groy" is incorrect. There is forward slash in the closing tag.

Text View should be TextView
Hapy should be Happy
"150" should be "150dp"
groy should be grey

1.Line 4 did'nt contain the dp at the end of layout_height value.
2.The TextView tag was not closed properly i.e. it did'nt contain the slash before closing angular bracket.
3.The background color name was'nt properly spelled.
4.The view name was not properly spelled.

I found all the 4 errors.

Space Between Text View
dp missing
darker_gray is correct color
closing tag not found

There should be no space between Text and View.
It should be Tex

1)There should be no space between Text and View.
It should be TextView
2)The unit in height is missing
It should be 150dp
3)the color should be darker_gray.

4. closing tag is missing

1. It has to be "TextView" without the gap
2. Instead of "groy" the color is "gray"
3. Line 4: The unit "dp" to set the height is missing
4. There is no correct closing tag
5. (Hapy should be changed to Happy)

there should be no space between TextView
There should be a forward slash before closing angle bracket
the unit of layout height should be mentioned- 150 dp
the spellings of gray color

Correct one, but don't let me go to the next steps.
---TextView <-- not: Text View
android:text="Happy Birthday" <-- grammar
android:layout_width="150dp"
android:layout_height="150dp" <-- missing dp
android:background="@android:color/darker_gray" <-- spelling

closign tag with "/>"

Correct code is: below (there are 4 errors)

1. TextView not Text View
2. Height with dp, "150dp"
3. Background color is darker_gray not darker_groy
4. At the end is / missing before >
5. Happy Birthday should be correctly written but that will not cause an error

1. Changed Text View to TextView in line 1.
2. Changed 150 to 150dp in line 4.
3. Changed groy to gray in line 5.
4. Changed > to /> in line 6.

The name TextView was separated in two words, not in CamelCase format.
The attribute android:layout_height had a value of "150" instead of "150dp".
The value of the attribute was typed "@android:color/darker_groy" instead or "@android:color/darker_gray".
The closing tag was wrong typed. "/" was missing.

I didn't notice the typo in "Hapy Birthday" :P

#Line 1
Line 1: Tag Text is not a supported opening tag.
<Text View should be <TextView

#Line 2
Spelling error, not a syntax error.
android:text="Hapy Birthday" should be android:text="Happy Birthday"

#Line 3
OK

#Line 4
The attribute android:layout_height does not support the value 150 (Line 4)
android:layout_height="150" should be android:layout_height="150dp"

#line 5
The color @android:color/darker_groy is not supported. Did you type it incorrectly?
android:background="@android:color/darker_groy" should be android:background="@android:color/darker_gray"

#Line 6
The tag TextView should be self-closing. This means it should end with /> .
> should be />

Syntax errors:

1. TextView should be camel case without space
2. Missing "dp" after 150 in height
3. Misspelled gray as groy
4. Missing forwardslash so the tag is closed

Other errors:
Happy is spelled incorrecly and missing an "h"

TextView with space between words
lack of 'dp' in height
typo in background color 'groy'
lack of closing bracket

TextView element has a space
android:layout_height is missing 'dp'
gray is misspelled
forward slash is missing from closing tag

Problems:

1. The name of the view i wrong. Correct TextView (no spaces)
2. The value for the attribute android:layout_height is not correct, the dp was missing
3. The value for the attribute android:color was spelled wrong: groy instead of gray
4. The closing tag is not correct, the sign / is missing

1.The name of the view is not right.
2.The height attribute has missing the dp.
3.The color attribute has a typo groy instead of gray.
4. No / before >.

1. line - name of the view should be "TextView"
2. line - value missing "dp"
3. line - color is misspelled, it should be "gray"
4. line - not code error, but grammatical. It should be "Happy Birthday!"

And now I have forget on the closing bracket! :)

• TextView, not Text View
• 150dp, not 150
• darker_gray, not darker_groy
• />, not >

There is no '/' at the end of the tag.
The layout_height is missing the 'dp' suffix.
I think the color specification is mis-spelled, it says 'groy' i imagine it should say 'gray'.
The XML element Text View is incorrect. it should be TextView.

Text View should be TextView.
There is no DP in the height quotes.
darker_groy is probably not a color, so the computer does not recognize it.
There is no slash to close the tag.

TextView not text View
android:layout_height="150dp" not android:layout_height="150"
android:background="@android:color/darker_gray" not android:background="@android:color/darker_groy"
/> not >

Blocking errors

The following are errors/issues that would prevent the view to display properly:

• The tag name should be TextView instead of Text View.
• The attribute android:layout_height has a value of 150 and it should be 150dp.
• The color specified for the attribute android:background is misspelled. It should be @android:color/darker_gray instead of @android:color/darker_groy.
• The TextView tag is missing the forward slash before >. Because of that it fails to act as a self closing tag.

Bonus: Non-Blocking Issues

The following error/issue would not prevent the view to display properly but it would be worth fixing it before it's used in production.

• The value of the android:text attribute is misspelled. It should be Happy Birthday instead of Hapy birthday.

"darker_gray" not "darker_groy" at line 5;
"150dp" not "150", "dp" was missing at the end of line 4;
"TextView" not "Text View", get rid of the white space to achieve camel font at line 1;
Lastly, at line 6 (the last line), the code missed the forward slash to close the tag;
After fixing these 4 errors, I was able to get the intended TextView.

1.Text and View have a space between them
2.layout_height has the value 150 , it should be 150 dp
3.line 5: it should be darker_gray instead of darker_groy
4.the end tag is missing the /

• the closing tag is missing the / (slash)
• darker_groy is not a color, it should be darker_gray
• Text View should not have a space in between
• The attribute of android:layout_height is missing the "dp" unit of measurement

1. Text View should be written without spaces in between TextView
2. The tag TextView should be self-closing with />
3. "darker_groy" is not a valid color. It should be "@android:color/darker_gray"
4. The android:layout_height attribute should include the "dp" at the end i.e. "150dp"

Error 1: <Text View is written with a space between Text and View instead of the correct one, with no space between them: <TextView
Error 2: android:layout_height="150" doesn't have dp after 150 - the correct one is: android:layout_height="150dp"
Error 3: The color @android:color/darker_groy is not supported. The right color is @android:color/darker_gray
Error 4: The closing of the tag is not done. The tag should be closed with: />

1. <Text View should be written without the space like <TextView
2. Tag <TextView needs an auto closing tag at the end like />
3. The value of attribute android:layout_height= has to be "150dp"
4. The value of attribute android:background= was misspelled and has to be "@android:color/darker_gray"

1. Text View -> TextView
2. "150" -> "150dp"
3. "[...]/darker_gray" not groy
4. />

1. Text view should be written in camel case TextView
2. layout height should be "150dp"
3. the color is darker_gray
4. we need ot have a self-closing tag in the end />

Text view should be written as the following TextView
layout height should be "150dp"
the color is darker_gray
self-closing tag in the end /

1. the space between Text View is an error. The solution of this is to write TextView
2. the layout_height should be "150dp"
3. the colour should be darker_gray
4. there isn't the forward slash before the closing angle bracket
   Another error is Hapy with just a p. It should be Happy. :o)

• element name incorrect: TextView
• layout_height missing dp in the attribute: "150dp"
• color: darker_gray
• closing tag is wrong: />

1. no closing tag
2. Mispellings: "Hapy", "_groy"
3. Size value missed: dp
4. Space between words instead of CamelCase: Text View

1. The attribute name included a space
2. Layout height was missing the dp declaration
3. In background gray was spelled groy
4. It wasn't a self-closing tag

1. TextView instead of Text View,
2. 150 dp instaed of 150
3. self-closing tag
4. gray instead of groy

1. Space on tag name
2. No slash on the tag close
3. Missing "dp" on the value in line 4
4. Color name in line 5 was typed incorrectly

1. <Text View should be <TextView
2. android:layout_height="150" should be android:layout_height="150dp"
3. android:background="@android:color/darker_groy" should be android:background="@android:color/darker_grey"
4. Closing tag > should be />
5. Not really error: Hapy should be Happy!!!

1. There should be no space in between Text and View - instead of Text View it should be TextView
2. android:layout_height="150" should be "150dp"
3. android:background="@android:color/darker_groy" should be darker_gray not groy
4. Missing the / for the self-closing tag - should be /> on line6

1 TextView not Text View
4 150dp not 150
5 gray not groy
6 /> not >

1. The TextView tag is not written in CamelCase, there should not be a space in between.
2. The height attribute value is "150dp", not "150".
3. The background attribute value has a word miswritten, it has to be "gray" instead of "groy".
4. The TextView tag is not ended correctly, it is missing a "/".

1. Happy birthday missed a 'p'
2. "Text View" needs to be "TextView"
3. Layout_height missed the 'dp'
4. The closing bracket missed a dash. It was ">" and needs to be "/>"

Line 1: The XML element TextView is written wrong.
Line 2: The android:text value "Happy Birthday" is misspelled.
Line 4 : android:layout_height value "150", the unit of unit of measurement is missing (dp).
Line 5: The android:background value "@android:color/darker_gray" is misspelled.
Line 6: The tag TextView has to end with />.

tag name should be TextView,
android:layout_height value should be equal to 150dp,
darker_gray,
slash

Line 1: Text and View should be together -> TextView;
Line 4: no units for height
Line 5 wrong color;
Line 6: no slash

Line 1: The XML element TextView is written wrong.
Line 2: The android:text value "Happy Birthday" is misspelled.
Line 4 : android:layout_height value "150", the unit of unit of measurement is missing (dp).
Line 5: The android:background value "@android:color/darker_gray" is misspelled.
Line 6: The tag TextView has to end with />.

<Text View
android:text="Hapy Birthday"
android:layout_width="150dp"
android:layout_height="150"
android:background="@android:color/darker_groy"

Line1: Text View should be TextView
Line:4 height should be in dp
Line:5 @android:color/darker_groy should be @android:color/darker_gray
Line:6 Closing tag />

1. Line 1: TextView is correct, Text View is not
2. Line 4: dp is missing
3. Line 5: color must be darker_gray
4. Line 6: / is missing in front of > (can/should be put at the end of Line 5)

At line 1 the TextView name is separated, that´s not correct. the correct way is: <TextView.
At line 2 we jast gotta a grammer error: "Hapy" It should be written "Happy".
At line 4 we gotta an error, the layout_height="150" should be written layout_height="150dp"
At line the color atribute must be written gray
And finally at last line we have closing the tag adding />

In line 1 is TextView
In line 4 is missing dp
In line 5 is gray
In line 6 is needed to close tag with />

• TextView was written sepparately instead of altogether
• The tag wasn't correctly closed (/ symbol was missing)
• android:layout_height's value lacked the dp unit
• android:background's value was misspelled (it should be "@android:color/darker_gray")

<Text View is wrong should be <TextView without the space between words
android:layout_height="150" dp is missing with 150
android:background="@android:color/darker_groy" groy should be grey
the ending tag is wrong, it must be />

Line 1: TextView is correct, Text View is not
Line 4: dp is missing
Line 5: color must be darker_gray
Line 6: / is missing in front of >

original error | fixes

<Text View | <TextView
android:background="@android:color/darker_groy" | android:background="@android:color/darker_gray"
android:layout_height="150" | android:layout_height="150dp"

                                                                                             |       / >

1. TextView should be just camel case with no spaces between words.
2. The tag TextView should be self-closing. This means it should end with /> .
3. The attribute android:layout_height has no unit of "dp".
4. The color @android:color/darker_groy has a typo, it should be "@android:color/darker_gray"

<Text View
android:text="Hapy Birthday"
android:layout_width="150dp"
android:layout_height="150"
android:background="@android:color/darker_groy"
>

Getting past the errors
Line 1 --> The element TextView should be writed in camel case, without inner spaces.
Line 2 --> No code error, but a grammar typo: "happy" with double p.
Line 3 --> Everything seem to be correct
Line 4 --> The value of the attribute android:layout_height should be expressed in an allowed unit, for example density-independent pixels (dp)
Line 5 --> The attribute for the background color has another typo, this one affecting code, it should be wrote as "@android:color/darker_gray"
Line 6 --> The self-closing tag for element TextView is not correct, forward slash is missing, it should be like this : "/>"

wrong syntax in Text View
parameter without dp in android:layout_height="150"
wrong spelling of gray in android:background="@android:color/darker_groy"
without closing tag />

First, the element name should be in CamelCase.
Then, the spelling of "Hapy Birthday" should be "Happy Birthday", the android:layout_height should have the dp as "150dp".
At last, the color of the background is spelled wrong! It should be"gray".

TextView separated
No dp información layout height
No close the TAG
The color is Gray
