    // In Android L MR-1 and prior devices, EditorInfo.packageName is not a reliable identifier
    // of the target application because:
    //   1. the system does not verify it [1]
    //   2. InputMethodManager.startInputInner() had filled EditorInfo.packageName with
    //      view.getContext().getPackageName() [2]
