Android TouchDelegate

Increase HitRect of View

Touch targets should be at least 48 x 48 dp.

Use TouchDelegate to extend the touchable area of a child view beyond the child's bounds. This an alternative to padding.

Android Maps Zoom Levels

Zoom levels

Maps have an integer “zoom level” which defines the resolution of the current view.

Level 0 (lowest zoom level): entire world can be seen on one map
Level 21+: individual buildings

Each succeeding zoom level doubles the precision in both horizontal and vertical dimensions:

256 * 2^N dp

Android Maps v2 MyLocation Button Position

Change MyLocation button position

It's easy to enable Zoom and MyLocation buttons but annoying to change where they overlay the Map.

Options

Use Map padding (are that will not overlap map controls)
Disable them and implement your own (probably safer than hack below)
Find the buttons by id and alter the layout params

Android Transparent Status Bar Fix

Fix status bar transparency

Note the adjusting the insets is a specific workaround for views that do not respect layout settings. View Pager has such problems.

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
private void setStatusBarTransparent() {
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().getDecorView().setSystemUiVisibility(
          View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);

getWindow().setStatusBarColor(Color.TRANSPARENT);
