dominicthomas / Update gradlew
Created October 23, 2013 10:07
Update the gradle wrapper. To update the system gradle use the guide here http://devopsnet.com/2012/05/24/upgrading-gradle/. The graddlew wrapper is packaged in with your project so is independent of the gradle version on your system.
gradlew with --refresh-dependencies

dominicthomas / Android ViewTreeObserver
Created November 1, 2013 14:41
How to add and remove a viewtreeobserver to an android view. This lets you call stuff when the view is finished rendering.
final ViewTreeObserver vto = myview.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@SuppressLint("NewApi")
@Override
public void onGlobalLayout() {
// do stuff
// remove this layout listener - as it will run every time the view updates
if (myview.getViewTreeObserver().isAlive()) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {

dominicthomas / Android Touch Area Extender
Last active November 1, 2016 07:28
A lovely android view touch area extender builder class. Made to provide a larger touch area to views that aren't standard clickable android view widgets. Works well on things like a small bit of text or a little drop down arrow. The code here is from a project that uses retrolamda and google's guava library for preconditions and optionals.
import android.graphics.Rect;
import android.view.TouchDelegate;
import android.view.View;
import com.google.common.base.Optional;
import com.google.common.base.Preconditions;
/**
* Utility used to extend the touchable area around a view in a viewgroup
* Usage: TouchAreaExtender.Builder.with(mReJamCaptionInput)

dominicthomas / PhoneNumberFormatter.java
Last active October 7, 2016 12:45
Simple class to format and convert to E164, mobile phone numbers for the UK and the US. Probably better to just use google libphonenumber.
public class PhoneNumberFormatter {
private final String simCountryIso;
private final Map<String, String> countryCodeMap = Collections.unmodifiableMap(
new HashMap<String, String>() {{
put("GB", "44");
put("US", "1");
}});
