Start activity over lockscreen from notification intent

Question

How do I start an activity over the lock screen after clicking on a notification? Whatever I do it asks for my password and starts the activity after I unlock. It doesn't even get to the onCreate methods.

    <activity
        android:name=".Locktask"
        android:configChanges="orientation"
        android:excludeFromRecents="true"
        android:noHistory="true"
        android:showOnLockScreen="true"
        android:showWhenLocked="true"
        android:taskAffinity=""
        android:exported="true"
        android:screenOrientation="portrait"
        android:launchMode="singleTask"
        android:theme="@style/AppTheme.NoActionBar" />


    Intent intent = new Intent(this, Locktask.class);

    PendingIntent pi = PendingIntent.getActivity(this, 2, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        NotificationChannel channel = new NotificationChannel("locknote",
                "locknote name",
                NotificationManager.IMPORTANCE_HIGH);
        channel.setDescription("shows layout over lock.");
        channel.enableLights(true);
        channel.setLightColor(Color.RED);
        channel.enableVibration(true);
        channel.setShowBadge(false);
        channel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
        channel.setVibrationPattern(new long[] { 0,0 });
        channel.enableVibration(false);
        if (mNotificationManager != null) {
            mNotificationManager.createNotificationChannel(channel);
        }
    }
    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this, "locknote")

            .setContentTitle("w")
            .setContentText("e")
            .setContentIntent(pi)
            .setSmallIcon(R.drawable.ic_action_lock_notification)
            .setPriority(NotificationCompat.PRIORITY_DEFAULT);

    NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);


    notificationManager.notify(2, mBuilder.build());

Not a duplicate as that answer's permissions have already been added.

Edit: SOVLED

For any poor souls in the future, the notification has to have a custom layout with setCustomContentView() and a onclickpendingintent set to that view. The pending intent should point to an intent service, it's the only way intents can get handled from notifications while still locked.

So would you like to start the activity by programmatically inserting your password the startup.? — Ümañg ßürmån, Oct 08 '18 at 17:29
@UmangBurman No I want to start the activity over the lock screen without unlocking the phone. So when the activity is closed again the phone is still locked. — user2430112, Oct 08 '18 at 17:30
I don't think it is possible. Do you think of an example app with this behavior? — Onur D., Oct 08 '18 at 17:59

@OnurD. I have and the problem is the notification doesn't seem to send the pending intent until the phone is unlocked. — user2430112, Oct 08 '18 at 18:26
Hello, can you post the solution? I am in the same problem. thanks — Schwarz54, Dec 10 '19 at 11:37
@Schwarz54 This was a while ago but the key things that got it to work for me were: you HAVE to use a custom layout for the notification and you also HAVE to extend 'IntentService' in whatever your intent target is. So if you have `Intent intent = new Intent(this, Locktask.class);` Locktask must extend IntentService. — user2430112, Dec 10 '19 at 23:15
And then from intentService you load the activity calling other intent like: `Intent intent = new Intent(this,Example.class); startActivity(intent)` did you remember is it that? — Schwarz54, Dec 11 '19 at 09:09

Try this:

    Intent intent = new Intent(this, Locktask.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
    PendingIntent pi = PendingIntent.getActivity(this, 2, intent, PendingIntent.FLAG_UPDATE_CURRENT);

I added them and it still asks to unlock the phone instead going into the activity. – user2430112 Oct 08 '18 at 19:31

I solved it. I needed to use an intent service to catch the pending intent. – user2430112 Oct 09 '18 at 00:08
