I am trying to open an activity when user clicks on Notification. I had issued following Intent as pending Intent
Intent caseIntent = new Intent(mContext, LoginActivity.class);
caseIntent.putExtra("priority", priority);
caseIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 0, caseIntent, PendingIntent.FLAG_CANCEL_CURRENT | PendingIntent.FLAG_UPDATE_CURRENT);
But when I click on the notification, if the app is not in forground the active which I have specified is not opening at all.
Is something wrong with this Intent?
I am receiving a notification from GCM ... in my GcmIntentService class I did this.
Intent notificationIntent = new Intent(GcmIntentService.this,
HomeActivity.class);
when I tap notification I want it to open a Fragment ..... I have my Fragments in HomeActivity.class from which I want to open Message Fragment.
Intent notificationIntent = new Intent(GcmIntentService.this,
HomeActivity.class );
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);
PendingIntent resultPendingIntent =
PendingIntent.getActivity(GcmIntentService.this, 0, notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
You can pass parameter with Intent like this
notificationIntent.putExtra("fragment", 1);
Where 1 is your fragment index and inside your HomeActivity you can use this
int id=getIntent().getIntExtra("fragment", 0);
viewPager.setCurrentItem(id);
I have two Activities in my app:
A - login Activity
B - main Activity
When the user clicks the login button in activity A I am starting a service. In the service's onCreate() method I launch activity B like this:
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
NotificationCompat.Builder builder = new NotificationCompat
.Builder(getApplicationContext());
builder.setContentIntent(pendingIntent);
builder.setContentTitle("Activity B in foreground service");
builder.setSmallIcon(R.drawable.ic_launcher);
startForeground(1, builder.build());
The problem is that Activity B launches minimized. I have to press the service button in the notification bar in order to get my activity maximized (fill the screen). How could I launch Activity B from service in normal way - without minimizing it (putting to background)?
Your code doesn't actually launch Activity B at all. All it does is create a Notification, that, if selected by the user, will launch Activity B.
If you want to actually launch Activity B, do this:
Intent notificationIntent = new Intent(this, MainActivity.class);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// Now launch the activity immediately
startActivity(notificationIntent);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
NotificationCompat.Builder builder = new NotificationCompat
.Builder(getApplicationContext());
... (rest of your code here)
Question already answered in android start activity from service
public void sendMessage(View view) {
Intent intent = new Intent(this, DisplayMessageActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
http://developer.android.com/training/basics/firstapp/starting-activity.html
Finally I found out the solution:
onCreate() method in service class:
#Override
public void onCreate() {
Intent notificationIntent = new Intent(getBaseContext(), MainActivity.class);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
getApplication().startActivity(notificationIntent);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
NotificationCompat.Builder builder = new NotificationCompat
.Builder(getApplicationContext());
builder.setContentIntent(pendingIntent);
builder.setContentTitle("Activity B runs in a foreground service");
builder.setSmallIcon(R.drawable.ic_launcher);
startForeground(1, builder.build());
}
In AndroidManifest.xml add this line in Activity element:
android:launchMode="singleTop"
I have the following code so far:
// Login Button
Intent loginIntent = new Intent(this.getApplicationContext(), LoginActivity.class);
loginIntent.putExtra("Source", "widgetLogin");
PendingIntent loginPIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, loginIntent, Intent.FLAG_ACTIVITY_NEW_TASK);
returnView.setOnClickPendingIntent(R.id.widget_login_button_login, loginPIntent);
return returnView;
However when I click on it nothing happens? I am sure I am just missing something with my intent.
Change
PendingIntent.getBroadcast(getApplicationContext(), 0, loginIntent, Intent.FLAG_ACTIVITY_NEW_TASK)
into
PendingIntent.getActivity(getApplicationContext(), 0, loginIntent, Intent.FLAG_ACTIVITY_NEW_TASK);
from Android Development, i implement a simple notification by the sample code, but in my app, i don't want to new intent and create the activity again, i just want to back to my last activity(it's a mediaplayer UI). if i use the sample code, it will create a new activity by
Intent resultIntent = new Intent(this, ResultActivity.class);
i comment relative code about new intent and got a notification, but didn't have idea how to back to my last activity...
back to my app from long press home key and touch my app is OK.
what i want is just like this behavior.
bleow is the sample code from Android Development, i comment the new intent portion.
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("My notification")
.setContentText("Hello World!");
/*Intent resultIntent = new Intent(this, ResultActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(ResultActivity.class);
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
mBuilder.setContentIntent(resultPendingIntent);*/
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(mId, mBuilder.build());
[UPDATE]
i thought i need to set flag for intent and properity for activity.
therefore, for the activity i want to back to i set
android:launchMode="singleInstance"
and because, i don't want a new activity from intent, i just want my last activity, so i add
Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY
from documentation i got that using Pendingintent.contentIntent it must include the FLAG_ACTIVITY_NEW_TASK flag and When using this flag, if a task is already running for the activity you are now starting, then a new activity will not be started; instead, the current task will simply be brought to the front of the screen with the state it was last in. so i also add
Intent.FLAG_ACTIVITY_NEW_TASK
but from logCat, i still saw that when i touch the notification for back to activity, the pendingintent still called onCreate() function rather than just show the last activity which still "alive".
If you want to call the Activity from background try this:
Intent intent = new Intent(this, YourLauncherActivity.class);
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
intent, 0);
mBuilder.setContentIntent(pendingIntent);
If you click the Notification while on Homescreen the last shown Activity of your App will be get to the foreground without starting it new. If the Activity was killed by the system you will get a new Activity.
I have used PendingIntent.getActivities instead of getActivity. This is working well in my project.
Intent backIntent = new Intent(this, HomeActivity.class);
backIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Intent notificationIntent = new Intent(this, NextActivity.class);
final PendingIntent pendingIntent = PendingIntent.getActivities(this, 1,
new Intent[] {backIntent, notificationIntent}, PendingIntent.FLAG_ONE_SHOT);
For me, this worked :
.setContentIntent(
PendingIntent.getActivity(
context,
0,
new Intent(context, YOUR_MAIN.class).setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP ),PendingIntent.FLAG_ONE_SHOT))
FLAG_ONE_SHOT : DO NOT CREATE TWICE (associated with
Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP)
In SingleTop mode, I use this method without define explicitly the root activity class:
Intent intent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER)
.setComponent(getPackageManager().getLaunchIntentForPackage(getPackageName()).getComponent());
and this to resume last activity from notification:
builder.setContentIntent(PendingIntent.getActivity(context, 0, intent, 0));
or this to resume last activity from a service:
try {
PendingIntent.getActivity(this, 0, intent, 0).send();
} catch (CanceledException e) {
e.printStackTrace();
}
Code hear
Intent resultIntent = new
Intent(getApplicationContext(),MainActivity.class);
resultIntent.putExtra("splash",2);
resultIntent.putExtra("message","test");
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addNextIntentWithParentStack(resultIntent);
resultIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK |Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent notifyPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
notificationCompatBuilder.setContentIntent(notifyPendingIntent);
Intent intent = this.getIntent();
Bundle extras = intent.getExtras();
if (extras != null) {
String extraValue = extras.getString("notificationType");
if(extraValue !=null){
int value = Integer.parseInt(extraValue);
if (value == 1) {
intent = new Intent(SplashActivity.this,MainActivity.class);
intent.putExtra("splash",value);
intent.putExtra("message", "fromsplash");
startActivity(intent);
finish();
} else
if (value == 2){
intent = new Intent(SplashActivity.this,MainActivity.class);
intent.putExtra("swip","2");
intent.putExtra("message", "test");
startActivity(intent);
finish();
}
}
}
}
