// You can write a simple gradle script to print your GRADLE_HOME directory.

task getHomeDir << {
    println gradle.gradleHomeDir
}
// and name it build.gradle.

// Then run it with:

gradle getHomeDir

Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

###Array ####Definition:

• Stores data elements based on an sequential, most commonly 0 based, index.
• Based on tuples from set theory.

I am using my custom ContentProvider to communicate with sqlite database. I would like to display on a list (using ListFragment), data that comes from two tables (with many to many relation). The only solution I can think of for such case is to use rawQuery. And the questions is, if it is a good practice, or should I solve this in some other way?

Example of tables:

Table A: ID, COLUMN_FROM_A

Table B: ID, COLUMN_FROM_B

Joining table AB: ID, FK_ID_A, FK_ID_B

Android Guide suggests to create a ContentProvider when you want to share you data with other applications. If you don't need this, you can just override method loadInBackgroud() of the CursorLoader class. For example write in you onCreateLoader:

return new CursorLoader( YourContext, null, YourProjection, YourSelection, YourSelectionArgs, YourOrder )
           {
               @Override
               public Cursor loadInBackground()
               {
                   // You better know how to get your database.
                   SQLiteDatabase DB = getReadableDatabase();
                   // You can use any query that returns a cursor.
