I've made an app which manage sms, I've created the notifications but when I click on them it starts another activity, I would like to know how to check if an activity has been stopped and resume it.
Here is the code used to create the pendingintent:
private void createNotification(SmsMessage sms, Context context){
final NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
String contentTitle = "";
// construct the Notification object.
final NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
.setContentTitle(contentTitle)
.setContentText(sms.getMessageBody())
.setSmallIcon(R.drawable.ic_launcher)
.setLargeIcon(getIconBitmap())
.setNumber(nmessages);
builder.setAutoCancel(true);
//(R.drawable.stat_sample, tickerText,
// System.currentTimeMillis());
// Set the info for the views that show in the notification panel.
//notif.setLatestEventInfo(this, from, message, contentIntent);
/*
// On tablets, the ticker shows the sender, the first line of the message,
// the photo of the person and the app icon. For our sample, we just show
// the same icon twice. If there is no sender, just pass an array of 1 Bitmap.
notif.tickerTitle = from;
notif.tickerSubtitle = message;
notif.tickerIcons = new Bitmap[2];
notif.tickerIcons[0] = getIconBitmap();;
notif.tickerIcons[1] = getIconBitmap();;
*/
// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(context, BasicActivity.class);
resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
// Because clicking the notification opens a new ("special") activity, there's
// no need to create an artificial back stack.
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
context,
0,
resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);
// Ritardo in millisecondi
builder.setContentIntent(resultPendingIntent);
nm.notify(R.drawable.ic_drawer, builder.build());
You need to set flags in your PendingIntent's ...like FLAG_UPDATE_CURRENT.
Here is all on it.
http://developer.android.com/reference/android/app/PendingIntent.html
Edit 1: I misunderstood the question.
Here are links to topics that had the same issue but are resolved:
resuming an activity from a notification
Notification Resume Activity
Intent to resume a previously paused activity (Called from a Notification)
Android: resume app from previous position
Please read the above answers for a full solution and let me know if it works.
Add this line to the corresponding activity in manifest file of your app.
android:launchMode="singleTask"
eg:
<activity
android:name=".Main_Activity"
android:label="#string/title_main_activity"
android:theme="#style/AppTheme.NoActionBar"
android:launchMode="singleTask" />
Try with this.
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
mContext).setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(mContext.getString(R.string.notif_title))
.setContentText(mContext.getString(R.string.notif_msg));
mBuilder.setAutoCancel(true);
// Set notification sound
Uri alarmSound = RingtoneManager
.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
mBuilder.setSound(alarmSound);
Intent resultIntent = mActivity.getIntent();
resultIntent.addCategory(Intent.CATEGORY_LAUNCHER);
resultIntent.setAction(Intent.ACTION_MAIN);
PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(pendingIntent);
NotificationManager mNotificationManager = (NotificationManager) mContext
.getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify(mId, mBuilder.build());
The only solution that actually worked for me after doing a lot of search is to do the following :
here you are simply launching of the application keeping the current stack:
//here you specify the notification properties
NotificationCompat.Builder builder = new NotificationCompat.Builder(this).set...(...).set...(..);
//specifying an action and its category to be triggered once clicked on the notification
Intent resultIntent = new Intent(this, MainClass.class);
resultIntent.setAction("android.intent.action.MAIN");
resultIntent.addCategory("android.intent.category.LAUNCHER");
PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
//building the notification
builder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(0, builder.build());
If the aforementioned solution didn't work, try to change the activity launch mode in your androidManifest.xml file from standard to singleTask.
<activity>
...
android:launchMode="singleTask
...
</activity>
This will prevent the activity from having multiple instances.

I am opening an activity from notification, which opens fine.
However, I want to open it's parent activity while I click 'back button', currently it exits the application directly. I want it to navigate to HomeScreenActivity.
Here is manifest declaration -
<activity
android:name="com.discover.activities.MyTrialsActivity"
android:exported="true"
android:parentActivityName="com.discover.activities.HomeScreenActivity"
android:screenOrientation="portrait">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.discover.activities.HomeScreenActivity" />
</activity>
Here is my code to generate notification -
public static PendingIntent getAction(Activity context, int actionId) {
Intent intent;
PendingIntent pendingIntent;
intent = new Intent(context, MyTrialsActivity.class);
//intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
// Adds the back stack
//stackBuilder.addParentStack(HomeScreenActivity.class);
stackBuilder.addParentStack(HomeScreenActivity.class);
// Adds the Intent to the top of the stack
stackBuilder.addNextIntent(intent);
// Gets a PendingIntent containing the entire back stack
pendingIntent =
stackBuilder.getPendingIntent(0 /*request code */, PendingIntent.FLAG_ONE_SHOT);
/*pendingIntent = PendingIntent.getActivity(context, 0 *//* Request code *//*, intent,
PendingIntent.FLAG_UPDATE_CURRENT*//*|PendingIntent.FLAG_ONE_SHOT*//*);*/
return pendingIntent;
}
/**
* Create and show a simple notification containing the message.
*
* #param message Message to show in notification
*/
public static void sendNotification(Context context, String message, int actionId) {
PendingIntent pendingIntent = NotifUtils.getAction((Activity) context, actionId);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("Title")
.setContentText(message)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setVibrate(new long[]{1000})
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
I you have everything set up correctly and it's still not working it might be that you need to uninstall and reinstall the app. It seems like some changes to the manifest are not updated properly when you run the app!
Solution -
I added my child activity as well in addParentStack(MyTrialActivity.class);
And it worked as expected.
I thought adding addNextIntent() should be doing that already, though it did not work that way..
I found the solution in android's documentation
// Intent for the activity to open when user selects the notification
Intent detailsIntent = new Intent(this, DetailsActivity.class);
// Use TaskStackBuilder to build the back stack and get the PendingIntent
PendingIntent pendingIntent =
TaskStackBuilder.create(this)
// add all of DetailsActivity's parents to the stack,
// followed by DetailsActivity itself
.addNextIntentWithParentStack(upIntent)
.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentIntent(pendingIntent);
And,
Here is the link.
Also, see this answer for more references.
Try using startActivities(Context context, Intent[] intents),
Intent homeIntent = new Intent(context, HomeScreenActivity.class);
Intent newIntent = new Intent(context, MyTrialsActivity.class);
Intent[] intents = new Intent[]{homeIntent, newIntent};
ContextCompat.startActivities(context, intents);
So we can start multiple activities at same time, so while pressing Back button it will go to Home Page instead of quiting the application.
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.
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);
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
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)
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());
I want to add a tap action (exit (finish)) to a notification.
I'm making a simple app with several classes, and I want them all finished when I tap the notification.
Here is my notification code:
mMN = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification n = new Notification();
n.icon = R.drawable.ic_launcher;
n.tickerText = "Tap this notification to exit";
n.when = System.currentTimeMillis();
Intent nid = new Intent(MainActivity.this, stopservice.class);
PendingIntent ci = PendingIntent.getActivity(this, 0, nid,PendingIntent.FLAG_UPDATE_CURRENT);
CharSequence ct = "TAP";
CharSequence tt = "Tap here to exit";
n.setLatestEventInfo(this,ct,tt,ci);
mMN.notify(NOTIFICATION_ID, n);
I'm making a reference to stopservice class (where it is my stop service code) on Intent nid, but I'm not quite sure if it's a correct reference.
hope that my question is clear.
You should be using a notification builder:
mMN = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Intent nid = new Intent(MainActivity.this, stopservice.class);
// If you were starting a service, you wouldn't using getActivity() here
PendingIntent ci = PendingIntent.getActivity(MainActivity.this, NOTIFICATION_ID, nid, PendingIntent.FLAG_UPDATE_CURRENT);
Notification.Builder builder = new Notification.Builder(MainActivity.this);
builder.setContentTitle("TAP")
.setContentText("Tap here to exit")
.setTicker("Tap this notification to exit")
.setSmallIcon(R.drawable.ic_launcher)
.setContentIntent(ci)
.setAutoCancel(true); // auto cancel means the notification will remove itself when pressed
mMN.notify(NOTIFICATION_ID, builder.getNotification());
Your code is set to launch the Activity "stopservice" (which technically should be "StopService" with naming conventions), are you sure that class is an Activity?
Also, make sure your Activity is registered in your app's manifest:
<activity android:name="[package-name].stopservice" android:label="#string/app_name"/>
I'm trying to make a notification when users pause my app. So to make it easier, users can go quickly to the application using notificaction. This is the code i'm using. It works for all versions before android 4 and i don't know which is the problem
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Titulo")
.setContentText("Titulo");
mBuilder.setOngoing(true);
// Creates an explicit intent for an Activity this
Intent resultIntent = new Intent(getApplicationContext(), MainActivity.class);
// put the flags
resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(MainActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify(mId, mBuilder.build());
So when i press the notification in android 4.0 and higher, the activity is created again instead of resume. any help please, i can't make it work.
EDIT ( forget about manifest singletop )
android:launchMode="singleTop" same result, not working...
My activity contains a map. I'm using the new version of google maps. v2.
I just tried PendingIntent.FLAG_CANCEL_CURRENT and seems to work for me
public void showNotification(String header,String message){
// define sound URI, the sound to be played when there's a notification
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Intent intent = new Intent(this, MainActivity.class);
//PendingIntent.FLAG_CANCEL_CURRENT will bring the app back up again
PendingIntent pIntent = PendingIntent.getActivity(MainActivity.this,PendingIntent.FLAG_CANCEL_CURRENT, intent, 0);
Notification mNotification = new Notification.Builder(this)
.setContentTitle(header)
.setContentText(message)
.setSmallIcon(R.drawable.ic_launcher)
.setContentIntent(pIntent)
.setSound(soundUri)
.addAction(R.drawable.ic_launcher, "View", pIntent)
.addAction(0, "Remind", pIntent)
.setOngoing(true)//optional
.build();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notificationManager.notify(0, mNotification);
}
Use android:launchMode="singleTop" in the manifest declaration of MainActivity
The only solution that actually worked for me after doing a lot of search is to do the following :
NotificationCompat.Builder builder = new NotificationCompat.Builder(this).set...(...).set...(..);
Intent resultIntent = new Intent(this, MainClass.class);
resultIntent.setAction("android.intent.action.MAIN");
resultIntent.addCategory("android.intent.category.LAUNCHER");
PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(0, builder.build());
this opens your current activiy without creating another one !
SOLUTION provided by #Patrick taken from the question and added as answer:
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.logo)
.setContentTitle(getString(R.string.txt))
.setContentText(getString(R.string.txt));
mBuilder.setOngoing(true);
// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(this, Activity.class);
resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
// 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.from(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(Activity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, 0);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// mId allows you to update the notification later on.
mNotificationManager.notify(mId, mBuilder.getNotification());
Since API level 16 (Jelly Bean), there is the possibility to add actions to a notification with
builder.addAction(iconId, title, intent);
But when I add an action to a notification and the action is pressed, the notification is not going to be dismissed.
When the notification itself is being clicked, it can be dismissed with
notification.flags = Notification.FLAG_AUTO_CANCEL;
or
builder.setAutoCancel(true);
But obviously, this has nothing to with the actions associated to the notification.
Any hints? Or is this not part of the API yet? I did not find anything.
When you called notify on the notification manager you gave it an id - that is the unique id you can use to access it later (this is from the notification manager:
notify(int id, Notification notification)
To cancel, you would call:
cancel(int id)
with the same id. So, basically, you need to keep track of the id or possibly put the id into a Bundle you add to the Intent inside the PendingIntent?
Found this to be an issue when using Lollipop's Heads Up Display notification. See design guidelines. Here's the complete(ish) code to implement.
Until now, having a 'Dismiss' button was less important, but now it's more in your face.
Building the Notification
int notificationId = new Random().nextInt(); // just use a counter in some util class...
PendingIntent dismissIntent = NotificationActivity.getDismissIntent(notificationId, context);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setPriority(NotificationCompat.PRIORITY_MAX) //HIGH, MAX, FULL_SCREEN and setDefaults(Notification.DEFAULT_ALL) will make it a Heads Up Display Style
.setDefaults(Notification.DEFAULT_ALL) // also requires VIBRATE permission
.setSmallIcon(R.drawable.ic_action_refresh) // Required!
.setContentTitle("Message from test")
.setContentText("message")
.setAutoCancel(true)
.addAction(R.drawable.ic_action_cancel, "Dismiss", dismissIntent)
.addAction(R.drawable.ic_action_boom, "Action!", someOtherPendingIntent);
// Gets an instance of the NotificationManager service
NotificationManager notifyMgr = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
// Builds the notification and issues it.
notifyMgr.notify(notificationId, builder.build());
NotificationActivity
public class NotificationActivity extends Activity {
public static final String NOTIFICATION_ID = "NOTIFICATION_ID";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
manager.cancel(getIntent().getIntExtra(NOTIFICATION_ID, -1));
finish(); // since finish() is called in onCreate(), onDestroy() will be called immediately
}
public static PendingIntent getDismissIntent(int notificationId, Context context) {
Intent intent = new Intent(context, NotificationActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
intent.putExtra(NOTIFICATION_ID, notificationId);
PendingIntent dismissIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
return dismissIntent;
}
}
AndroidManifest.xml (attributes required to prevent SystemUI from focusing to a back stack)
<activity
android:name=".NotificationActivity"
android:taskAffinity=""
android:excludeFromRecents="true">
</activity>
I found that when you use the action buttons in expanded notifications, you have to write extra code and you are more constrained.
You have to manually cancel your notification when the user clicks an action button. The notification is only cancelled automatically for the default action.
Also if you start a broadcast receiver from the button, the notification drawer doesn't close.
I ended up creating a new NotificationActivity to address these issues. This intermediary activity without any UI cancels the notification and then starts the activity I really wanted to start from the notification.
I've posted sample code in a related post Clicking Android Notification Actions does not close Notification drawer.
In new APIs don't forget about TAG:
notify(String tag, int id, Notification notification)
and correspondingly
cancel(String tag, int id)
instead of:
cancel(int id)
https://developer.android.com/reference/android/app/NotificationManager
In my opinion using a BroadcastReceiver is a cleaner way to cancel a Notification:
In AndroidManifest.xml:
<receiver
android:name=.NotificationCancelReceiver" >
<intent-filter android:priority="999" >
<action android:name="com.example.cancel" />
</intent-filter>
</receiver>
In java File:
Intent cancel = new Intent("com.example.cancel");
PendingIntent cancelP = PendingIntent.getBroadcast(context, 0, cancel, PendingIntent.FLAG_CANCEL_CURRENT);
NotificationCompat.Action actions[] = new NotificationCompat.Action[1];
NotificationCancelReceiver
public class NotificationCancelReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
//Cancel your ongoing Notification
};
}
You will need to run the following code after your intent is fired to remove the notification.
NotificationManagerCompat.from(this).cancel(null, notificationId);
NB: notificationId is the same id passed to run your notification
You can always cancel() the Notification from whatever is being invoked by the action (e.g., in onCreate() of the activity tied to the PendingIntent you supply to addAction()).
Just put this line :
builder.setAutoCancel(true);
And the full code is :
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setSmallIcon(android.R.drawable.ic_dialog_alert);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.google.co.in/"));
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
builder.setContentIntent(pendingIntent);
builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.misti_ic));
builder.setContentTitle("Notifications Title");
builder.setContentText("Your notification content here.");
builder.setSubText("Tap to view the website.");
Toast.makeText(getApplicationContext(), "The notification has been created!!", Toast.LENGTH_LONG).show();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
builder.setAutoCancel(true);
// Will display the notification in the notification bar
notificationManager.notify(1, builder.build());
Just for conclusion:
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
Intent intent = new Intent(context, MyNotificationReceiver.class);
intent.putExtra("Notification_ID", 2022);
PendingIntent pendingIntent = PendingIntent.getBroadcast(
context,
0,
intent,
...);
Notification notification = new NotificationCompat.Builder(...)
...
.addAction(0, "Button", pendingIntent)
.build();
notificationManager.notify(2022, notification);
and for dismiss the notification, you have two options:
approach 1: (in MyNotificationReceiver)
NotificationManager manager = (NotificationManager)
context.getSystemService(NOTIFICATION_SERVICE);
manager.cancel(intent.getIntExtra("Notification_ID", -1));
approach 2: (in MyNotificationReceiver)
NotificationManagerCompat manager = NotificationManagerCompat.from(context);
manager.cancel(intent.getIntExtra("Notification_ID", -1));
and finally in manifest:
<receiver android:name=".MyNotificationReceiver" />
builder.setAutoCancel(true);
Tested on Android 9 also.
