java - NullPointerException (@PhoneWindow:onKeyUpPanel:1002) {main}

Question

I get strange exceptions in my analytics lately.

java.lang.NullPointerException

I am missing a lead on what I can do to prevent this.

Until LG fixes this issue (which could be months, depending on how long it takes them to release new firmware), the following workaround worked for me. Just add the following code to your Activity class:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
   if (keyCode == KeyEvent.KEYCODE_MENU && "LGE".equalsIgnoreCase(Build.BRAND)) {
       return true;
   }
   return super.onKeyDown(keyCode, event);
}

@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
   if (keyCode == KeyEvent.KEYCODE_MENU && "LGE".equalsIgnoreCase(Build.BRAND)) {
       openOptionsMenu();
       return true;
   }
   return super.onKeyUp(keyCode, event);
}
