Targeting S+ (version 33 ) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified

Question

App crashes at runtime with the following error :

Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent. Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

I tried all solutions available but the app still crashing on Android 12.

private Notification buildNotification() {
    int playButtonResId = isPaused ? R.drawable.ic_play_arrow_white_24dp : R.drawable.ic_pause_white_24dp;

    PendingIntent clickIntent = PendingIntent.getActivity(
            this, 1,
            new Intent(this, MainActivity.class),
            PendingIntent.FLAG_IMMUTABLE);

Answer 1

PendingIntent clickIntent;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
    clickIntent = PendingIntent.getActivity(
        getApplicationContext(),
        1,
        intent, 
        PendingIntent.FLAG_IMMUTABLE | PendingIntent.FLAG_UPDATE_CURRENT
    );
} else {
    clickIntent = PendingIntent.getActivity(getApplicationContext(), 1, intent, 0);
}
