Hairy-ish code for getting unique ID from Android device

gistfile1.java

public String getUniqueId(final Context context) {
  String uniqueId = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);
  // Ugh, Motorola's Droid 2.2 devices return this ID, which they copied directly from the Android emulator. If
  // we see that device ID, we should instead use the telephony manager's ID instead.
  if(uniqueId == null || uniqueId.equals("9774d56d682e549c")) {
    TelephonyManager telephonyManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
    uniqueId = telephonyManager.getDeviceId();
  }
  if(uniqueId == null) {
    ErrorController.logErrorRemotely("No unique ID found for device!", null);
  }
  return uniqueId;
}
