This is my code to set up a notification with buttons.

Intent receiverIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        PendingIntent pReceiverIntent = PendingIntent.getActivity(ctx, 1, receiverIntent, 0);
        Intent clearIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        PendingIntent pClearIntent = PendingIntent.getActivity(ctx, 1, clearIntent, 0);

        Intent colorsIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        PendingIntent pColorsIntent = PendingIntent.getActivity(ctx, 1, colorsIntent, 0);

        Intent animationIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        PendingIntent pAnimation = PendingIntent.getActivity(ctx, 1, animationIntent, 0);

        Notification.Builder builder;
        builder = new Notification.Builder(ctx).setSmallIcon(R.drawable.ic_launcher).setAutoCancel(false)
                .setContentTitle("Draw Me: A Live Wallpaper").setContentText("Never get bored again!")
                .setContentIntent(pReceiverIntent).addAction(R.raw.ic_menu_close_clear_cancel, "Clear", pClearIntent)
                .addAction(R.raw.ic_menu_edit, "Colors", pColorsIntent).addAction(R.raw.ic_menu_play_clip, "Animation", pAnimation);
        Notification notification =;

        NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0, notification);

Notification is showing up but buttons don't. My device has Android 4.1.1 I set up this notification in a Fragment. What am I doing wrong? Thanks!



Let me tell you something which is really awkward. If you have anything in your Ongoing Notification, You wont see the buttons. Typically it happens when you have phone connected to PC via USB. Hope this solves your problem

The code won't work without an icon. So, add the setSmallIcon call to the builder chain like this for it to work:


Android Oreo (8.0) and above

Android 8 introduced a new requirement of setting the channelId property by using a NotificationChannel.

NotificationManager mNotificationManager;

NotificationCompat.Builder mBuilder =
    new NotificationCompat.Builder(mContext.getApplicationContext(), "notify_001");
Intent ii = new Intent(mContext.getApplicationContext(), RootActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 0, ii, 0);

NotificationCompat.BigTextStyle bigText = new NotificationCompat.BigTextStyle();
bigText.setBigContentTitle("Today's Bible Verse");
bigText.setSummaryText("Text in detail");

mBuilder.setContentTitle("Your Title");
mBuilder.setContentText("Your text");

mNotificationManager =
    (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);

// === Removed some obsoletes
    String channelId = "Your_channel_id";
    NotificationChannel channel = new NotificationChannel(
                                        "Channel human readable title",

I found out that I had to register "switchButtonListener" in AndroidManifest.xml

<receiver android:name="SettingsActivity$switchButtonListener" />

Source: Android Activity with no GUI

Later I found out that I can also use code like this to achieve the same thing without modifying the manifest.

switchButtonListener = new SwitchButtonListener();
registerReceiver(switchButtonListener, new IntentFilter(SWITCH_EVENT));


public class switchButtonListener extends BroadcastReceiver {
    public void onReceive(Context context, Intent intent) {
        Log.d("TAG", "test");



Intent switchIntent = new Intent(LangService.SWITCH_EVENT);
PendingIntent pendingSwitchIntent = PendingIntent.getBroadcast(context, 0, switchIntent, 0);

notificationView.setOnClickPendingIntent(, pendingSwitchIntent);

Note that this way I can declare the switchButtonListener class without the static attribute (if not static, it would crash in the previous example) giving me much more flexibility.
Don't forget to call unregisterReceiver() later.

You may have to register your listner in AndroidManifest.xml. Take a look at this one

Here's the answer, which I had to find elsewhere. It seems that you must have the following element:

    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />

inside your AndroidManifest.xml file. Once I added this, then right-clicked on the project name to launch the Android Application, the app then showed up in the menu panel.

Eclipse put this (intent-filter) element there for my first experimental application, but it did not do me the favor for the second one I created, which I'm still debugging for yet other (and probably Eclipse-related) reasons. (I probably filled something out wrong when creating the new Android project.)
