How to add pause and cancel button to custom download notification android

Question

I have created a custom notification for Downloading an mp3 file from a given URL. But I need to know how to add pause and cancel button to the custom notification I created.

Here is the partial code for custom Notification :

 if (!downloadUrl.toString().isEmpty()) {
                                    DownloadManager.Request request = new DownloadManager.Request(Uri.parse(downloadUrl));
                                    request.setMimeType("audio/MP3");
                                    request.setTitle(vMeta.getTitle());
                                    request.allowScanningByMediaScanner();
                                    request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_HIDDEN);
                                    request.setDestinationInExternalPublicDir(storage, vMeta.getTitle() + extension);
                                    final DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);

                                    final long id = manager.enqueue(request);


                                    registerReceiver(new DownloadReceiver(id, storage, vMeta.getTitle() + extension),
                                            new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
                                    mBuilder =  new NotificationCompat.Builder(getApplicationContext());
                                    Intent intent = new Intent();
                                    PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);
                                    mBuilder.setContentIntent(pendingIntent);
                                    mBuilder.setSmallIcon(R.drawable.ic_music_video_white_24dp);
                                    mBuilder.setContentTitle("Downloading");
                                    mBuilder.setContentText(vMeta.getTitle());
                                    mBuilder.setOngoing(false);
                                    //mBuilder.addAction();

Answer 1

You need to set particular action to notification with media control you can add particular action with relative pending intent

.addAction(R.drawable.ic_prev, "Previous", prevPendingIntent) 
.addAction(R.drawable.ic_pause, "Pause", pausePendingIntent) 
.addAction(R.drawable.ic_next, "Next", nextPendingIntent) 

You also need to set media style using below code

 .setStyle(MediaNotificationCompat.MediaStyle()
 .setShowActionsInCompactView(1 /* #1: pause button \*/)
 .setMediaSession(mMediaSession.getSessionToken()))

Answer 2

Refer to a simple example，everything is in the code:

public class MainActivity extends AppCompatActivity {
    private DownloadReceiver downloadReceiver = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        init();

        findViewById(R.id.button1).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
//                notifyFirst();
                notifySecondNotification();
            }
        });
    }

    private void init() {
        downloadReceiver = new DownloadReceiver();
        IntentFilter intentFilter = new IntentFilter(DownloadReceiver.ACTION_1);
        intentFilter.addAction(DownloadReceiver.ACTION_2);
        registerReceiver(downloadReceiver, intentFilter);
    }


    private void notifySecondNotification() {

        Intent button1I = new Intent(DownloadReceiver.ACTION_1);
        PendingIntent button1PI = PendingIntent.getBroadcast(this, 0, button1I, 0);

        Intent button2I = new Intent(DownloadReceiver.ACTION_2);
        PendingIntent button2PI = PendingIntent.getBroadcast(this, 0, button2I, 0);
        /*
         * use RemoteViews to custom notification layout
         * R.layout.notification
         */
        RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.notification);
        /*
         * bind click event
         */
        remoteViews.setOnClickPendingIntent(R.id.notificationButton1, button1PI);
        remoteViews.setOnClickPendingIntent(R.id.notificatinoButton2, button2PI);

        Notification notification = new NotificationCompat.Builder(this)
                .setTicker("tttttttttt")
                .setContentTitle("setContentTitle")
                .setContentText("setContentText")
                .setSmallIcon(android.R.drawable.ic_menu_report_image)
                /**
                 * set remoteViews
                 */
                .setContent(remoteViews)
                .build();

        NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
        notificationManager.notify(0, notification);

    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        unregisterReceiver(downloadReceiver); 
    }
}

your download receiver example:

public class DownloadReceiver extends BroadcastReceiver {
    public static final String ACTION_1 = "Press11111";
    public static final String ACTION_2 = "Press22222";

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        assert action != null;
        String toastStr = "you touch";
        if (action.equals(ACTION_1)) {
            //download......
            Toast.makeText(context, toastStr + "1111111", Toast.LENGTH_SHORT).show();
        } else if (action.equals(ACTION_2)) {
           //cancle download......
            Toast.makeText(context, toastStr + "2222222", Toast.LENGTH_SHORT).show();
        }
    }

}
