Question

I want to implement the following scenario:

When a user presses the Home key a Notification is displayed in the Status bar and the App is normally hidden. When user taps the Notification App is normally restored.

Here is my code for this:

private int NOTIFICATION = R.string.local_service_started;
private NotificationManager mNM;

private void showNotification() {
    CharSequence text = getText(R.string.local_service_started);
    Notification notification = new Notification(R.drawable.icon, text, System.currentTimeMillis());
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, JingleCartoucheActivity.class), 0);
    notification.setLatestEventInfo(this, getText(R.string.local_service_label), text, contentIntent);
    mNM.notify(NOTIFICATION, notification);
}

@Override
public void onPause() {
    super.onPause();
    if (!isFinishing()) {
        showNotification();
    }
}

@Override
public void onResume() {
    super.onResume();
    mNM.cancel(NOTIFICATION);
}

All of this is working well except for one thing:

When the App is run and the user rotates the phone, the notification is created and immediately destroyed. Is there a way to detect the phone orientation change in onPause() and not show this Notification?

Answer 1

You can get the current orientation using the getResources().getConfiguration().orientation. At the onCreate you store the orientation value and then you can compare it later. Be sure to store the value into a static variable, since when you rotate the phone, the activity is destroyed and so are it’s values.
