Clear Application Data with ADB at the command line

You can use package manager (pm) to clear data for installed apps (same as pressing the 'clear data' button in the app settings on your device).

Run this adb command, replacing 'com.company.games.game' with your package name from AndroidManfiest.xml

adb shell pm clear com.company.games.game

This method depends on the 'pm' tool being resident on the Android device, which is not always the case.

NullPointerException at android.widget.ArrayAdapter.createViewFromResource

Crashes while using code like this:

AlertDialog.Builder builder = new AlertDialog.Builder(StatusMenuConflicts.this);

builder.setTitle("Star Traders RPG");

builder.setIcon(R.drawable.icon);

final String[] items = new String[6];

items[0] = getString(R.string.status);

The stack trace won't contain your code.
