I have a class which extends BroadcastReceiver that gets called whenever new Wifi scan results are available (the receiver is registered in the manifest with the Scan_Results broadcast as the intent-filter).
From this class, I want to be able to show a notification to the user. Currently, I pass the context that is received as a parameter in the onReceive method of my broadcast intent class to a "show notification" method of another class.
When it gets to the line:
myNotificationManager.notify(notificationId, notification);
it fails with the following exception:
java.lang.IllegalArgumentException: contentView required: pkg=com.mumfordmedia.trackify id=2131034122 notification=Notification(vibrate=null,sound=null,defaults=0x0,flags=0x0)
Any idea why this is happening? All I can think of is because the context that I am getting from the onReceive parameter is not ... for lack of a better phrase, "right for the job"...
Any ideas?
Thanks,
Max.
ContentView is the view which is required when the notification is clicked. The code below works fine and setLatestEventInfo() is required method.
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.ic_launcher,
"Hello from service", System.currentTimeMillis());
Intent intent = new Intent(this, MainActivity.class);
notification.setLatestEventInfo(this, "contentTitle", "contentText",
PendingIntent.getActivity(this, 1, intent, 0));
manager.notify(111, notification);
Not sure exactly why it wasnt working before but here is the code I got it working with:
Declare the following outside of any method:
int YOURAPP_NOTIFICATION_ID = 1234567890;
NotificationManager mNotificationManager;
Then in the onReceive method call the following:
mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
showNotification(context, R.drawable.icon, "short", false);
Then declare the following method:
private void showNotification(Context context, int statusBarIconID, String string, boolean showIconOnly) {
// This is who should be launched if the user selects our notification.
Intent contentIntent = new Intent();
// choose the ticker text
String tickerText = "ticket text";
Notification n = new Notification(R.drawable.icon, "ticker text", System.currentTimeMillis());
PendingIntent appIntent = PendingIntent.getActivity(context, 0, contentIntent, 0);
n.setLatestEventInfo(context, "1", "2", appIntent);
mNotificationManager.notify(YOURAPP_NOTIFICATION_ID, n);
}
You have to call Notification.setLatestEventInfo().
Use this code along with your notification
Intent intent = new Intent(this, MusicDroid.class);
PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);
notification.setLatestEventInfo(this, "This is the title",
"This is the text", activity);
notification.number += 1;
nm.notify(NOTIFY_ID, notification);
From what I can tell, when you're creating you notification to pass to the Notification manager, you're not giving it a content view to display. Review the line where you actually create the notification to see if you're actually giving the notification a view to display.
For those who are using NotificationCompat, the following code will work:
NotificationCompat.Builder n = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.icon).setContentText("Notify Title").setContentText("Sample Text");
NotificationManager nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
Intent i = new Intent(this,MainActivity.class);
PendingIntent ac = PendingIntent.getActivity(this, 0, i, 0);
n.setContentIntent(ac);
nm.notify(12222, n.build());

Notification setAutoCancel(true) doesn't work if clicking on Action
I have a notification with an action within it. When I tap on the notification it gets removed from the list. However, when I click on the Action it successfully completes the Action (namely makes a call), but when I return to the list of notifications, it remains there.
Relative code of the AlarmReceiver:
public class AlarmReceiver extends BroadcastReceiver {
Meeting meeting;
/**
* Handle received notifications about meetings that are going to start
*/
#Override
public void onReceive(Context context, Intent intent) {
// Get extras from the notification intent
Bundle extras = intent.getExtras();
this.meeting = extras.getParcelable("MeetingParcel");
// build notification pending intent to go to the details page when click on the body of the notification
Intent notificationIntent = new Intent(context, MeetingDetails.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
notificationIntent.putExtra("MeetingParcel", meeting); // send meeting that we received to the MeetingDetails class
notificationIntent.putExtra("notificationIntent", true); // flag to know where the details screen is opening from
PendingIntent pIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
// build intents for the call now button
Intent phoneCall = Call._callIntent(meeting);
if (phoneCall != null) {
PendingIntent phoneCallIntent = PendingIntent.getActivity(context, 0, phoneCall, PendingIntent.FLAG_CANCEL_CURRENT);
int flags = Notification.FLAG_AUTO_CANCEL;
// build notification object
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
Notification notification = builder.setContentTitle("Call In")
.setContentText(intent.getStringExtra("contextText"))
.setTicker("Call In Notification")
.setColor(ContextCompat.getColor(context, R.color.colorBluePrimary))
.setAutoCancel(true) // will remove notification from the status bar once is clicked
.setDefaults(Notification.DEFAULT_ALL) // Default vibration, default sound, default LED: requires VIBRATE permission
.setSmallIcon(R.drawable.icon_notifications)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(meeting.description))
.addAction(R.drawable.icon_device, "Call Now", phoneCallIntent)
.setCategory(Notification.CATEGORY_EVENT) // handle notification as a calendar event
.setPriority(Notification.PRIORITY_HIGH) // this will show the notification floating. Priority is high because it is a time sensitive notification
.setContentIntent(pIntent).build();
notification.flags = flags;
// tell the notification manager to notify the user with our custom notification
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notification);
}
}
}
use this flag:
Notification.FLAG_AUTO_CANCEL
inside this:
int flags = Notification.FLAG_AUTO_CANCEL;
Notification notification = builder.build();
notification.flags = flags;

Ok turns out it's a known problem already, and it needs extra code to be done (keeping reference to notification through id). Have no clue why API does not provide this, as it seems very logical to do. But anyways,
see this answer in stackoverflow:
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?
I faced this problem today, and found that FLAG_AUTO_CANCEL and setAutoCanel(true), both work when click on notification,
but not work for action click
so simply, in the target service or activity of action, cancel the notification
NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
manager.cancelAll();
or if have more notification
manager.cancel(notificationId);
You have created two pending intent use in boths and change Flag too.
PendingIntent pIntent = PendingIntent.getActivity(context, (int) System.currentTimeMillis(), notificationIntent, 0);
PendingIntent phoneCallIntent = PendingIntent.getActivity(context, (int) System.currentTimeMillis(), phoneCall, PendingIntent.FLAG_UPDATE_CURRENT);
// CHANGE TO THIS LINE
PendingIntent pIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
PendingIntent phoneCallIntent = PendingIntent.getActivity(context, 0, phoneCall, PendingIntent.FLAG_CANCEL_CURRENT);
I can use the following code to display a notification icon of missed calls, I hope to click the icon to open system Missed Calls UI, how can I do ? Thanks!
At present, I can open ui.CallerMain.class UI if I remove the comment.
BTW, in system Missed Calls UI, missed calls are listed in there.
private void ShowMissCallNotification(Context myContext,String myContentText) {
NotificationManager notificationManager = (NotificationManager) myContext.getSystemService(android.content.Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(android.R.drawable.sym_call_missed,
myContext.getString(R.string.app_name),
System.currentTimeMillis());
notification.flags |= Notification.FLAG_ONGOING_EVENT;
notification.flags |= Notification.FLAG_NO_CLEAR;
CharSequence contentTitle= "Title";
CharSequence contentText =myContentText;
//Intent notificationIntent = new Intent(myContext, ui.CallerMain.class);
//PendingIntent contentItent = PendingIntent.getActivity(myContext, 0, notificationIntent, 0);
//notification.setLatestEventInfo(myContext, contentTitle, contentText,contentItent);
notificationManager.notify(NotificationID, notification);
}
Set a Pending Intent to the notification which will trigger the Call History.
First create an intent with Call Log
Intent resultIntent = new Intent();
resultIntent.setAction(Intent.ACTION_VIEW);
resultIntent.setType(CallLog.Calls.CONTENT_TYPE);
Then obtain the PendingIntent
PendingIntent resultPendingIntent =
PendingIntent.getActivity(
this,
0,
resultIntent,
PendingIntent.FLAG_UPDATE_CURRENT
);
Then set the PendingIntent to your notification builder
NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
.setSmallIcon()
.setContentTitle()
.setContentText()
.setContentIntent(resultPendingIntent);
notificationManager.notify(id, builder.build());
Now clicking the notification will open the Call Log.
Update: The code commented out in your snippet will work if you create the Intent as mentioned above in this answer. But please be aware that the method by which you are creating notification has been deprecated. Use NotificationCompat class from the support library in future.
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.

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 using the following code to show a notification in my android application, but using this, with the notification an activity also shows up (i.e. a black blank screen) I dont want this screen, but just a simple notification and when the user clicks the notification then I want to launch the activity. What should be done to this code?
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Notification notify = new Notification(R.drawable.mcube_logo, "Message Sent", Calendar.getInstance().getTimeInMillis());
Intent intent = new Intent(RecieveAlarm.this, otherActivity.class);
PendingIntent pendingIntent =PendingIntent.getActivity(RecieveAlarm.this, 1, null, PendingIntent.FLAG_CANCEL_CURRENT);
notify.setLatestEventInfo(RecieveAlarm.this, "Title", "Details", pendingIntent);
notificationManager.notify(0, notify);
I suggest you to use:
Notification not = new Notification(idIcon, text, System.currentTimeMillis());
PendingIntent pInt = PendingIntent.getActivity(ctx, 0, new Intent(ctx, the_class_to_call), 0);
not.setLatestEventInfo(ctx, app_name, text, pInt);
and then not.notify....
use AlertDialog, then launch your desired activity on positive button click
Im trying to start a new activity once i press a notification...the related code is:
NotificationManager notifManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification note = new Notification(R.drawable.android, "New E-mail", System.currentTimeMillis());
PendingIntent intent = PendingIntent.getActivity(this, 0, new Intent(this, DatabaseActivity.class), 0);
note.setLatestEventInfo(this, "New E-mail", "You have one unread message.", intent);
notifManager.notify(NOTIF_ID, note);
But the activity just dsnt begin..the notification pops up..but if i click it nothin happens...plz advice!!!
Pardon the obvious question but is DatabaseActivity referenced in your manifest?
May be you can use getApplicationContext() instead of this in the pendingIntent definition.
