Clicking on Notification is not starting intended activity?

Question

I am using GCM in my application and also using NotificationManager to Create a Notification whenever GCM message is received.Till now everything is working perfectly and GCM message is showing correctly in Notification area, but when I click on the notification it should start an activity of my application which will display the message detail which is not happening. Every-time I click on notification it does not start any activity and it remains as is.My code for creating Notification is :

private void sendNotification(String msg) {
        SharedPreferences prefs = getSharedPreferences(
                DataAccessServer.PREFS_NAME, MODE_PRIVATE);
        mNotificationManager = (NotificationManager) this
                .getSystemService(Context.NOTIFICATION_SERVICE);
        Intent intent = new Intent(this, WarningDetails.class);
        Bundle bundle = new Bundle();
        bundle.putString("warning", msg);
        bundle.putInt("warningId", NOTIFICATION_ID);
        intent.putExtras(bundle);
        // The stack builder object will contain an artificial back stack for
        // the
        // started Activity.
        // This ensures that navigating backward from the Activity leads out of
        // your application to the Home screen.
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        // Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(WarningDetails.class);
        // Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(intent);

        PendingIntent contentIntent = stackBuilder.getPendingIntent(0,
                PendingIntent.FLAG_UPDATE_CURRENT);

        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                this).setSmallIcon(R.drawable.weather_alert_notification)
                .setContentTitle("Weather Notification")
                .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
                .setContentText(msg);
        String selectedSound = prefs.getString("selectedSound", "");
        if (!selectedSound.equals("")) {
            Uri alarmSound = Uri.parse(selectedSound);
            mBuilder.setSound(alarmSound);

        } else {
            Uri alarmSound = RingtoneManager
                    .getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
            mBuilder.setSound(alarmSound);
        }

        if (prefs.getBoolean("isVibrateOn", false)) {
            long[] pattern = { 500, 500, 500, 500, 500, 500, 500, 500, 500 };
            mBuilder.setVibrate(pattern);
        }

        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    }

I updated my code to support Preserving Navigation when Starting an Activity just like it happens in Gmail application using the Android developers website since then it stopped working.Someone Please guide me what I am missing or doing wrong in this code.

Answer 1

My problem got solved I just have to add PendingIntent.FLAG_ONE_SHOT flag as well , so I replaced :

PendingIntent contentIntent = stackBuilder
                .getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

to

PendingIntent contentIntent = stackBuilder
                .getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT
                        | PendingIntent.FLAG_ONE_SHOT);

Answer 2

I encountered the same issue and resolved it by adding android:exported="true" to the activity declaration in AndroidManifest.xml.

Here you just passed your Intent into pendingintent: see below

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

 PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
and set this contentintent into your Notification:

Notification noti = new NotificationCompat.Builder(context)
                    .setSmallIcon(icon_small)
                    .setTicker(message)
                    .setLargeIcon(largeIcon)
                    .setWhen(System.currentTimeMillis())
                    .setContentTitle(title)
                    .setContentText(message)
                    .setContentIntent(**contentIntent**)
                    .setAutoCancel(true).build();

This may help you.

if you launch the intended activity using Action String dont forget to add

<intent-filter>
       <action android:name="YOUR ACTION STRING"/>
       <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

inside <activity></activity> tag

Answer 5

The activity that you want to launch has to be designated as a LAUNCHER activity in your manifest - otherwise it won't launch via a Pending Intent. Add the following to your in the AndroidManifext.xml

<activity
...
android:exported="true">
<intent-filter>
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

Otherwise you will need to use an Activity that is already designated as a LAUNCHER (such as your MAIN activity)

Answer 6

Do some thing like this on generateNotification() method ..

Replace your activity with Splash.Java class in it.

/**
     * Issues a notification to inform the user that server has sent a message.
     */
    @SuppressWarnings("deprecation")
    private static void generateNotification(Context context, String message) {
        int icon = R.drawable.ic_launcher;
        long when = System.currentTimeMillis();
        //message = "vivek";
       // Log.d("anjan", message.split("~")[0]);
        //Toast.makeText(context, message, Toast.LENGTH_LONG).show();

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

        String title = context.getString(R.string.app_name);
        Log.d("anjan1", title);
        String text_message = context.getString(R.string.title_activity_main);
        Log.d("anjan1", text_message);

        Intent notificationIntent = new Intent(context, Splash.class);
        // set intent so it does not start a new activity
        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;

        // Play default notification sound
        notification.defaults |= Notification.DEFAULT_SOUND;

        // Vibrate if vibrate is enabled
        notification.defaults |= Notification.DEFAULT_VIBRATE;
        notificationManager.notify(0, notification);      

    }

Try this instead of the last line :

mNotificationManager.notify(0, mBuilder.getNotification());
