Unfortunately, I was unable to find a resolution to this issue in other StackOverflow posts so I apologize in advance for re-posting this question. Essentially, I have an AppWidget that creates a Notification. I want the user to click the Notification to launch an Activity. The AppWidget and Activity are in the same APK.
The following code is all in the AppWidget. Clicking on the Notification broadcasts a custom Intent which is received by the AppWidget.
The problem is that the Activity does not appear to launch, even though logcat demonstrates that the custom Intent has indeed been broadcast. The only clue is the logcat message reiterated in the post title.
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Constants.BROWSER_INTENT)) {
launchActivity(context, R.layout.appwidget, R.id.launch_button, Activity.class);
}
super.onReceive(context, intent);
}
private void displayNotification(Context context, String ticker, String title, String msg) {
Intent intent = new Intent(context, ThisWidget.class);
intent.setAction(Constants.BROWSER_INTENT);
PendingIntent pending = PendingIntent.getActivity(context, 0, intent, 0);
NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon, ticker, System.currentTimeMillis());
notification.setLatestEventInfo(context, title, msg, pending);
notificationManager.notify(1, notification);
}
Some notes:
Pressing a button to execute launchActivity() works (it launches the
Activity)
launchActivity uses Intent.FLAG_ACTIVITY_NEW_TASK as
recommended by Android lifecycle documentation
Has anyone solved this issue when launching an Activity from a Notification press?
er, figures, I answered my own question just minutes after posting it. I guess I was over-complicating the implementation by using an Intent action. I changed these lines:
Intent intent = new Intent(context, ThisWidget.class);
intent.setAction(Constants.BROWSER_INTENT);
PendingIntent pending = PendingIntent.getActivity(context, 0, intent, 0);
to this:
Intent intent = new Intent(context, Activity.class);
PendingIntent pending = PendingIntent.getActivity(context, 0, intent, 0);
and it worked.
Sorry for the bogus post.

I found similar questions, but none of the solutions helped me.
I have a broadcast receiver intercepting sms and forwarding the sms text to another activity. The other activity should display the latest received text.
But the other activity is ALWAYS displaying the first text received after the app was started for the first time. New sms-texts are not displayed.
What I tried:
Played around with the parameters of Pending Intent (unique random int and all 4 update options) - didnt help so far.
PendingIntent contentIntent = PendingIntent.getActivity(context, **rand.nextInt(50) + 1**, intent, **FLAG_UPDATE_CURRENT**);
Here's the relevant code from the Broadcast Receiver, the notification which is also triggered shows the new and correct text each time.
private void showNotification(Context context) {
Intent intent = new Intent(context, DisplayMSG.class);
intent.putExtra(EXTRA_MESSAGE, str);
Random rand = new Random();
PendingIntent contentIntent = PendingIntent.getActivity(context, rand.nextInt(50) + 1, intent, FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("RPT Notification")
.setContentText(str + Integer.toString(n));
mBuilder.setContentIntent(contentIntent);
mBuilder.setDefaults(Notification.DEFAULT_SOUND);
mBuilder.setAutoCancel(true);
NotificationManager mNotificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, mBuilder.build());
}
}
And here's the part from the receiving activity:
Intent intent = getIntent();
String message = intent.getStringExtra(SmsReceiver.EXTRA_MESSAGE);
TextView textView = (TextView) findViewById(R.id.tView);
textView.setText(message);
Let me know if you need more code. But I hope this should be sufficient, since it's basically working, it's just not transferring the new texts.
EDIT:
Thanks to CommonsWare here is the solution, I just added this method to the receiving activity:
#Override
protected void onNewIntent(Intent intent)
{
super.onNewIntent(intent);
TextView textView = (TextView) findViewById(R.id.tView);
textView.setText(intent.getStringExtra(SmsReceiver.EXTRA_MESSAGE));
}
And here's the part from the receiving activity
If the activity is already running, that is the wrong Intent. Override onNewIntent() and use the Intent that is passed in to it. getIntent() always returns the Intent used to create the activity, not any subsequent ones that brought an existing instance back to the foreground.
I want to make it so when one plugs in there headset a notification icon appears. I've made it so when the phone turns on this runs which starts the MainActivity class which has the code for the notification icon in the OnCreate method so it just automatically starts. The problem with that is that it starts the whole activity and app, which I don't want. I just want the icon to appear. How could I go about this? Thank You!
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Intent myIntent = new Intent(context, MainActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(myIntent);
}
The above code starts the MainActivity on boot.
Notification Icon Code
//Notification Icon Starts
NotificationManager nm=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification=new Notification(R.drawable.icon_notification, "Icon Notification", System.currentTimeMillis());
Context context=MainActivity.this;
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, MainActivity.class), Notification.FLAG_ONGOING_EVENT);
notification.flags = Notification.FLAG_ONGOING_EVENT;
notification.setLatestEventInfo(this, "Notification Icon", "Touch for more options", contentIntent);
Intent intent=new Intent(context,MainActivity.class);
PendingIntent pending=PendingIntent.getActivity(context, 0, intent, 0);
nm.notify(0, notification);
//Notification Icon Ends
As I wrote in your last question, add a <receiver> in your manifest that listens for the ACTION_HEADSET_PLUG broadcast. The documentation shows Intent extras that you can use to find out if the headset is plugged in (state), etc.
I posted a solution that allows you to monitor the headphone state (wired and bluetooth), over here. This solution could easily be extended to allow you to display a notification.

How to set click listener for notification?
(3 answers)
Closed 9 years ago.
I had set a notification in my app. Its working fine. If i click the notification in statusbar it takes to my app.
Now i need to set some work if the notification is clicked where can i set this?
Is there any method that implicitly got invoked when a notification is clicked?
Also i want to remove that notification if it is clicked,how to do so?
this is my code
notifManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Intent inty=getIntent();
note = new Notification(R.drawable.icon, "New E-mail", System.currentTimeMillis());
PendingIntent intent = PendingIntent.getActivity(MainActivity.this, 0, inty, 0);
note.setLatestEventInfo(MainActivity.this, "New E-mail", "You have one unread message.", intent);
notifManager.notify(R.string.search_hint, note);
You could add some extra data to the intent and then in your activity look for it in the onCreate and onNewIntent methods.
For example:
inty.putExtra("came from notification", true);
You can then read that out via the intent passed to onNewIntent or in onCreate by using getIntent().
intent.getBooleanExtra("came from notification", false);
Try to call broadcastReceiver it may helpful for your requirement,
Intent notificationIntent = new Intent(this, dummy_activity.class);
notificationIntent.setAction("android.intent.action.MAIN");
notificationIntent.addCategory("android.intent.category.LAUNCHER");
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT |
Notification.FLAG_AUTO_CANCEL);
// Now, once this dummy activity starts send a broad cast to your parent activity and finish the pending activity
//remember you need to register your broadcast action here to receive.
BroadcastReceiver call_method = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action_name = intent.getAction();
if (action_name.equals("call_method")) {
// call your method here and do what ever you want.
}
}
};
registerReceiver(call_method, new IntentFilter("call_method"));
I build custom notification that contain button and i want to listin when user press on it.
The button should not open any activity but only logic staff like change song.
the Code:
RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.notification);
contentView.setTextViewText(R.id.toptext, nowPlayingTitle);
//this not work
Intent intent = new Intent(this, receiver.class);
intent.putExtra("UNIQ", "1");
PendingIntent pendingIntent = PendingIntent.getBroadcast(
this.getApplicationContext(), 234324243, intent, PendingIntent.FLAG_CANCEL_CURRENT)
contentView.setOnClickPendingIntent(R.id.imageButtonPlay,
pendingIntent);
notification.contentView = contentView;
// this is to return to my activity if click somwhere else in notification
Intent notificationIntent = new Intent(this, MYACTIVITY.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.contentIntent = contentIntent;
mNotificationManager.notify(NOTIFICATION_ID, notification);
I don't get the hang of the setOnClickPendingIntent what need to be in the second param?
How can i just call a function after user press on the button?
im probably missing something cause i dont understand the receiver side and what happend after user press
You are missing the fact that the button you created actually doesn't belong to your application. It is created in another context, in another process. There is no way it can call your function.
Instead, when the user taps the button, that pending intent is fired. You can catch it by your receiver (in your activity), check some parameters and do the action.
Or you can implement a service and handle this intent in background. I'd prefer this way.
thanks for quick answer. I try using receiver but it never fired.
The code is in the main question and i created for the reciever class the following code:
public class receiver extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
Bundle bundle = intent.getExtras();
}
}
but click on the notification never fire the receiver ( Test on debug mode )
Got a little problem that's been bugging me..
I've set up my application to receive PUSH notifications from Urban Airship and that all works fine, but when I tap on a notification in the notifications center, nothing happens.
I want my app to open when a user taps a PUSH notification - what can I do to achieve this?
Any help is as always greatly appreciated.
Thanks
Create a pending Intent to start the activity and set it in notification using setLatestEventInfo.
Example:
Context context = getApplicationContext();
CharSequence contentTitle = "My notification";
CharSequence contentText = "Hello World!";
Intent notificationIntent = new Intent(this, MyClass.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
More info can be found here
You need to use a custom notification builder and use one of your activities as the PendingIntent.
https://docs.urbanairship.com/android-lib/reference/com/urbanairship/push/CustomPushNotificationBuilder.html
Following one of their sample projects (https://github.com/urbanairship/android-samples/tree/master/app/src/main/java/com/urbanairship/sample), you can extend the AirshipReceiver class and then override the onReceive method. This did the trick for me:
#Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
String action = intent.getAction();
if (action.equals(PushManager.ACTION_NOTIFICATION_OPENED)) {
Intent launch = new Intent(Intent.ACTION_MAIN);
launch.setClass(UAirship.shared().getApplicationContext(), MyHome.class);
launch.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
launch.putExtra("doWhatever",true);
UAirship.shared().getApplicationContext().startActivity(launch);
}
}
you have to call pendingIntent before call .setAutoCancel(true);
look at my builder :
NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext(),channel_id).setSmallIcon(R.drawable.logo).setSound(uri).setVibrate(new long[]{1000,1000,1000,1000,1000})
.setOnlyAlertOnce(true).setContentIntent(pendingIntent).setAutoCancel(true);
