Buka aplikasi setelah mengklik Notifikasi

Saya memiliki pemberitahuan di aplikasi saya dengan kode berikut:

//Notification Start

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

   int icon = R.drawable.n1; 
   CharSequence tickerText = "Call Blocker";
   long when = System.currentTimeMillis(); //now
   Notification notification = new Notification(icon, tickerText, when);
   Intent notificationIntent = new Intent(context, Main.class);
   PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

   Context context = getApplicationContext();
   CharSequence title = "Call Blocker";
   text = "Calls will be blocked while driving";

   notification.setLatestEventInfo(context, title, text, contentIntent);

   notification.flags |= Notification.FLAG_ONGOING_EVENT;
   notification.flags |= Notification.FLAG_SHOW_LIGHTS;
   notificationManager.notify(1, notification);

}

Notifikasi saya menyala dengan sangat baik, tetapi masalah saya adalah, ketika saya mengklik notifikasi di Pusat Pemberitahuan, aplikasi saya tidak dimulai.

Pada dasarnya, setelah mengklik notifikasi saya tidak ada yang terjadi! Apa yang harus saya lakukan, untuk memulai aktivitas Utama saya setelah mengklik notifikasi saya. Terima kasih.

Lihat kode di bawah ini. Saya menggunakan itu dan itu membuka HomeActivity saya.

    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);

    Intent notificationIntent = new Intent(context, HomeActivity.class);

    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);

    PendingIntent intent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);

    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(0, notification);

Berikut contoh penggunaan class NotificationCompact.Builder yang merupakan versi terbaru untuk membuat notifikasi.

private void startNotification() {
    Log.i("NextActivity", "startNotification");

 // Sets an ID for the notification
      int mNotificationId = 001;

    // Build Notification , setOngoing keeps the notification always in status bar
    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.ldb)
                    .setContentTitle("Stop LDB")
                    .setContentText("Click to stop LDB")
                    .setOngoing(true);

    // Create pending intent, mention the Activity which needs to be 
    //triggered when user clicks on notification(StopScript.class in this case)

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, StopScript.class), PendingIntent.FLAG_UPDATE_CURRENT);


    mBuilder.setContentIntent(contentIntent);


    // Gets an instance of the NotificationManager service
   NotificationManager mNotificationManager =
            (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);


    // Builds the notification and issues it.
    mNotificationManager.notify(mNotificationId, mBuilder.build());


}

Silakan gunakan kode di bawah ini untuk contoh lengkap pemberitahuan sederhana, dalam kode ini Anda dapat membuka aplikasi setelah mengklik Pemberitahuan, itu akan menyelesaikan masalah Anda.

public class AndroidNotifications extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button notificationButton = (Button) findViewById(R.id.notificationButton);

        notificationButton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Timer timer = new Timer();
                timer.schedule(new TimerTask() {
                    @Override
                    public void run() {
                        // Notification Title and Message
                        Notification("Dipak Keshariya (Android Developer)",
                                "This is Message from Dipak Keshariya (Android Developer)");
                    }
                }, 0);
            }
        });
    }

    // Notification Function
    private void Notification(String notificationTitle,
            String notificationMessage) {
        NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        android.app.Notification notification = new android.app.Notification(
                R.drawable.ic_launcher, "Message from Dipak Keshariya! (Android Developer)",
                System.currentTimeMillis());

        Intent notificationIntent = new Intent(this, AndroidNotifications.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
                notificationIntent, 0);

        notification.setLatestEventInfo(AndroidNotifications.this,
                notificationTitle, notificationMessage, pendingIntent);
        notificationManager.notify(10001, notification);
    }
}

Contoh Notifikasi Sederhana

Sepertinya Anda melewatkan bagian ini,

notification.contentIntent = pendingIntent;

Coba tambahkan ini dan itu akan berhasil.

Gunakan kode di bawah ini untuk membuat pemberitahuan untuk aktivitas terbuka. Ini bekerja untuk saya. Untuk kode lengkap

 Intent myIntent = new Intent(context, DoSomething.class);
 PendingIntent pendingIntent = PendingIntent.getActivity(
        context, 
        0, 
        myIntent, 
        Intent.FLAG_ACTIVITY_NEW_TASK);

 myNotification = new NotificationCompat.Builder(context)
   .setContentTitle("Exercise of Notification!")
   .setContentText("Do Something...")
   .setTicker("Notification!")
   .setWhen(System.currentTimeMillis())
   .setContentIntent(pendingIntent)
   .setDefaults(Notification.DEFAULT_SOUND)
   .setAutoCancel(true)
   .setSmallIcon(R.drawable.ic_launcher)
   .build();

 notificationManager = 
   (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
 notificationManager.notify(MY_NOTIFICATION_ID, myNotification);

Gunakan ini:

    Notification mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.ic_music)
                    .setContentTitle(songName).build();


    mBuilder.contentIntent=  PendingIntent.getActivity(this, 0,
            new Intent(this, MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);

contentIntent akan menangani aktivitas pembukaan saat pemberitahuan diklik

public void addNotification()
{
    NotificationCompat.Builder mBuilder=new NotificationCompat.Builder(MainActivity.this);
    mBuilder.setSmallIcon(R.drawable.email);
    mBuilder.setContentTitle("Notification Alert, Click Me!");
    mBuilder.setContentText("Hi,This notification for you let me check");
    Intent notificationIntent = new Intent(this,MainActivity.class);
    PendingIntent conPendingIntent = PendingIntent.getActivity(this,0,notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);

    mBuilder.setContentIntent(conPendingIntent);

    NotificationManager manager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(0,mBuilder.build());
    Toast.makeText(MainActivity.this, "Notification", Toast.LENGTH_SHORT).show();

}

Berkat posting di atas, inilah baris utama - disaring dari jawaban kode yang lebih panjang - yang diperlukan untuk menghubungkan notifikasi dengan click listener set untuk membuka beberapa Aktivitas aplikasi.

private Notification getNotification(String messageText) {

    Notification.Builder builder = new Notification.Builder(this);
    builder.setContentText(messageText);
    // ...

    Intent appActivityIntent = new Intent(this, SomeAppActivity.class);

    PendingIntent contentAppActivityIntent =
            PendingIntent.getActivity(
                            this,  // calling from Activity
                            0,
                            appActivityIntent,
                            PendingIntent.FLAG_UPDATE_CURRENT);

    builder.setContentIntent(contentAppActivityIntent);

    return builder.build();
}

public static void notifyUser(Activity activity, String header,
        String message) {
    NotificationManager notificationManager = (NotificationManager) activity
            .getSystemService(Activity.NOTIFICATION_SERVICE);
    Intent notificationIntent = new Intent(
            activity.getApplicationContext(), YourActivityToLaunch.class);
    TaskStackBuilder stackBuilder = TaskStackBuilder.create(activity);
    stackBuilder.addParentStack(YourActivityToLaunch.class);
    stackBuilder.addNextIntent(notificationIntent);
    PendingIntent pIntent = stackBuilder.getPendingIntent(0,
            PendingIntent.FLAG_UPDATE_CURRENT);
    Notification notification = new Notification.Builder(activity)
            .setContentTitle(header)
            .setContentText(message)
            .setDefaults(
                    Notification.DEFAULT_SOUND
                            | Notification.DEFAULT_VIBRATE)
            .setContentIntent(pIntent).setAutoCancel(true)
            .setSmallIcon(drawable.notification_icon).build();
    notificationManager.notify(2, notification);
}

Gunakan contoh saya ...

 public void createNotification() {
        NotificationManager notificationManager = (NotificationManager) 
              getSystemService(NOTIFICATION_SERVICE);
        Notification notification = new Notification(R.drawable.icon,
            "message", System.currentTimeMillis());
        // Hide the notification after its selected
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        Vibrator vibrator = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
        long[] pattern = { 0, 100, 600, 100, 700};
        vibrator.vibrate(pattern, -1);
     Intent intent = new Intent(this, Main.class);
     PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);
     String sms = getSharedPreferences("SMSPREF", MODE_PRIVATE).getString("incoming", "EMPTY");
        notification.setLatestEventInfo(this, "message" ,
            sms, activity);
        notification.number += 1;
        notificationManager.notify(0, notification);

      }

Ini adalah cara saya mendekati.

public class AppFCMService extends FirebaseMessagingService {

    private final static String TAG = "FCM Message";
    String notify, requstId, Notification;
    PendingIntent pendingIntent;

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
        //split string and getting order id from notification
        String Str = remoteMessage.getNotification().getBody();
        String[] tmp;
        tmp = Str.split(" ");
        String temp1 = tmp[0];
        String temp2 = tmp[1];
        String id = tmp[2];
        notify = temp1 + " " + temp2;
        requstId = id;
        showNotification(remoteMessage.getNotification().getBody());
    }

    private void showNotification(String messageBody) {
        // check whether session has been initiated or not
        if (new SessionHelper(getApplicationContext()).isLoggedIn()) {

            if (notify.equalsIgnoreCase("Travel request")) {

                Intent intent = new Intent(this, ViewTravelDetailsActivity.class);
                intent.putExtra("TravelRequestID", requstId);
                intent.putExtra("BackPress", "Notify");
                pendingIntent = PendingIntent.getActivity(this, 0, intent,
                        PendingIntent.FLAG_ONE_SHOT);

            } else if (notify.equalsIgnoreCase("Timesheet replied")) {

                Intent intent = new Intent(this, ViewReplyActivity.class);
                intent.putExtra("timesheetActivityID", requstId);
                intent.putExtra("BackPress", "Notify");
                intent.putExtra("RealmData", "DeleteRealm");
                intent.putExtra("isToday", "true");
                pendingIntent = PendingIntent.getActivity(this, 0, intent,
                        PendingIntent.FLAG_ONE_SHOT);
            } else {

                Intent intent = new Intent(this, Dashboard.class);
                intent.putExtra("timesheetActivityID", requstId);
                pendingIntent = PendingIntent.getActivity(this, 0, intent,
                        PendingIntent.FLAG_ONE_SHOT);
            }
        } else {

            Intent intent = new Intent(this, LoginActivity.class);
            intent.putExtra("timesheetActivityID", requstId);
            pendingIntent = PendingIntent.getActivity(this, 0, intent,
                    PendingIntent.FLAG_ONE_SHOT);
        }

        Bitmap notifyImage = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setLargeIcon(notifyImage)
                .setColor(Color.parseColor("#FFE74C3C"))
                .setContentTitle("TEST")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);
        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, notificationBuilder.build());
    }
}
