Android helper class for showing cheat sheets (tooltips) for icon-only UI elements on long-press. This is already default platform behavior for icon-only action bar items and tabs. This class provides this behavior for any other such UI element.

Android ColorMatrixColorFilter example: Creates a 'ghost' bitmap version of the given source drawable (ideally a BitmapDrawable).

`classes.dex` method count helpers. Requires smali/baksmali from https://code.google.com/p/smali/ and dexdump from the build-tools in the Android SDK be on your PATH.
function dex-method-count() {
cat $1 | head -c 92 | tail -c 4 | hexdump -e '1/4 "%d\n"'
}
function dex-method-count-by-package() {
dir=$(mktemp -d -t dex)
baksmali $1 -o $dir
for pkg in `find $dir/* -type d`; do
smali $pkg -o $pkg/classes.dex
count=$(dex-method-count $pkg/classes.dex)
name=$(echo ${pkg:(${#dir} + 1)} | tr '/' '.')

Sample usage of the "android.app.Application.ActivityLifecycleCallbacks" class.
public class MainActivity extends Activity {
private final MyActivityLifecycleCallbacks mCallbacks = new MyActivityLifecycleCallbacks();
@Override
protected void onCreate(Bundle savedInstanceState) {
// Always register before calling into the super class.
getApplication().registerActivityLifecycleCallbacks(mCallbacks);
super.onCreate(savedInstanceState);

Tiny utility class that helps avoid book-keeping code when dealing with registering and unregistering BroadcastReceivers. Hopefully, this will help you get rid of "Activity has leaked IntentReceiver that was originally registered here" messages without resorting to using boolean flags to keep track of your BroadcastReceivers.
