Question

I want to create a notification and I have this bit of code that worked before but now gives me a null pointer at the last line.

Any ideas as to what may cause this?

I know it may be hard with this bit of code that I have provided, I just need a hint as to what could possibly cause this.

   private void showNotification() {

    CharSequence text = getText(R.string.myString);


    Notification notification = new Notification(R.drawable.playbackstart, text,
            System.currentTimeMillis());


    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, MyActivity.class), 0);


    notification.setLatestEventInfo(this, getText(R.string.myString),
                   text, contentIntent);



    mNM.notify(R.string.myString, notification);
}

Answer 1

mNM is null, since R.string.myString must exist otherwise it won’t compile, and notification is used before, therefore cannot be null, otherwise would gotten a NPE earlier. Therefore, check mNM. Or post the entire code where mNM is initialized.
