Unable to cancel the notification from the notification tray when different layouts used for expand/collapse

I have a share option in the notification tray. So, I have used 2 custom views in my code.
1. Expandable Notification Layout
2. Normal Notification Layout
The UI is working fine. But, notifications are misbehaving. If I click the first notification or share first item in the notification, it works perfectly. But, If I click the last notification, then it opens the app but notification is not cleared from the notification tray. Also, the strange thing is, after clicking the notification,small icon which comes in the status bar disappears and now if i click the notification, it doesn't respond. I'm cancelling the notification. That's why second time, when i click it doesn't work. This was not happening when I used default builder layout for normal view.
Here is my code:
//setup a expanded notification layout
RemoteViews expandedView=new RemoteViews(context.getPackageName(), R.layout.custom_notification);
expandedView.setImageViewResource(R.id.image_logo, R.drawable.ic_launcher);
SimpleDateFormat dateFormat = new SimpleDateFormat("hh:mm aa");
String time = dateFormat.format(new Date(when));
expandedView.setTextViewText(R.id.current_time, time);
expandedView.setTextViewText(R.id.title, context.getResources().getString(R.string.app_name));
expandedView.setTextViewText(R.id.text, message);
expandedView.setTextViewCompoundDrawables(R.id.share, R.drawable.gcm_share, 0, 0, 0);
//set a normal notification layout
RemoteViews collapsedView=new RemoteViews(context.getPackageName(), R.layout.custom_notification_normal_layout);
collapsedView.setTextViewText(R.id.text, message);
notificationId = ((int) System.currentTimeMillis() % 1000000);
//register listenr for Share Icon
setBtnListeners(expandedView, requestID, message, context, notificationId);
`Bitmap largeIcon = ((BitmapDrawable) context.getResources().getDrawable(R.drawable.ic_launcher)).getBitmap()`;
//Construct notification Builder
NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(context);
mNotifyBuilder
.setWhen(when)
.setSmallIcon(icon)
.setLargeIcon(largeIcon)
.setContentTitle(message)
.setStyle(new NotificationCompat.BigTextStyle().bigText(message));
notification = mNotifyBuilder.build();
//assign the vies to the notification builder
notification.bigContentView = expandedView;
notification.contentView = collapsedView;
//create pending Intent
Intent notificationIntent;
//notificationIntent = new Intent(context, Launcher.class);
notificationIntent = new Intent(context, SplashActivity.class);//Sritapana189
notificationIntent.putExtra(BundleKeys.NORMAL_PUSH, 1);
notificationIntent.putExtra(BundleKeys.DEFAULT_NOTI_NAV, nav);
notificationIntent.putExtra(BundleKeys.FROM_GCM, true);
notificationIntent.putExtra(ApplicationConstants.GCMKeys.GCM_NOTIFICATION_ID, notificationId);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent contentIntent = PendingIntent.getActivity(context, requestID, notificationIntent, 0); //Modified
notification.contentIntent = contentIntent;
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(notificationId, notification);
//Registering the share icon of notification tray
private static void setBtnListeners(RemoteViews notificationView, int requestId, String message, Context context, int notificationId) {
Intent shareBtnIntent = new Intent(context, GcmTransparentActivity.class);
shareBtnIntent.putExtra(ApplicationConstants.GCMKeys.BREAKING_NEWS, message);
shareBtnIntent.putExtra(ApplicationConstants.GCMKeys.GCM_NOTIFICATION_ID, notificationId);
PendingIntent pendingIntent = PendingIntent.getActivity(context, requestId, shareBtnIntent, 0);
notificationView.setOnClickPendingIntent(R.id.share, pendingIntent);
}
//SplashActivity recieving Pending Inent
//here I'm retrieving the payload data and saving it and then cancelling the notification
Utility.cancelNotification(gcmNotificationId, getApplicationContext());
public static void cancelNotification(int id, Context ctx) {
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager nMgr = (NotificationManager) ctx.getSystemService(ns);
nMgr.cancel(id);
}
The only change i did in my code is I added custom layout for the normal view.After this change, it's misbehaving when last notification item is clicked. Is there anything I'm missing. please help me to sort out this strange issue.

try this,
problem may be because you are not getting the notification id properly
quick fix can be,
Notification nNotificationManager nMgr = (NotificationManager) ctx.getSystemService(ns);
nMgr.cancel(id);
replace this with ,
Notification nNotificationManager nMgr = (NotificationManager) ctx.getSystemService(ns);
nMgr.cancelAll();

I resolved my issue. The problem was with the RemoteViews. I had made them local and making them final solved my issue
final RemoteViews expandedView=new RemoteViews(context.getPackageName(), R.layout.custom_notification);
final RemoteViews collapsedView=new RemoteViews(context.getPackageName(), R.layout.custom_notification_normal_layout)

Auto Cancel Custom Notification using RemoteView

I have created a custom layout notification using remoteview. Problem I'm facing is, How to autoCancel the notification once the user touches it.
I did try few things, but none is giving desired result.
Find Code below:
RemoteViews remoteView = new RemoteViews(this.getPackageName(), R.layout.notification_layout);
NotificationCompat.Builder builder = new NotificationCompat.Builder(MainActivity.this);
builder.setSmallIcon(R.drawable.ic_launcher);
Intent intent = new Intent(MainActivity.this, SecondActivity.class);
PendingIntent pIntent = PendingIntent.getActivity(MainActivity.this, RQST_CODE, intent, PendingIntent.FLAG_CANCEL_CURRENT);
remoteView.setOnClickPendingIntent(R.id.btnNotification, pIntent);
builder.setAutoCancel(true);
builder.setContent(remoteView);
Notification notify = builder.build();
notify.flags |= Notification.FLAG_AUTO_CANCEL;
NotificationManager notiManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notiManager.notify(NOTY_ID, notify);

For others who have a custom layout and want auto cancel to work,
If clicking anywhere on notification is ok, then don't use remoteView.setOnClickPendingIntent. Because any view with OnClick Listener overrides the notification main OnClick Listener.
Use setContentIntent instead:
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
builder.setContentTitle("title");
builder.setContentText("contect");
builder.setSmallIcon(#smallicon);
builder.setWhen(#when);
builder.setContent(remoteViews);
builder.setContentIntent(onClickPendingIntent); // use this
builder.setAutoCancel(true);

The way I achieved this is by creating BroadcastReceiver which controls button clicks from Notification. Create something like this :
public class NotificationButtonListener extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
int action = intent.getIntExtra("mode", -1);
switch (action) {
// do some things depending on action if there are more stuff to do
}
}
}
Don't forget to add your BroadcastListener to your manifest file:
<receiver android:name=".NotificationButtonListener">
And you can create a helper class for creating and cancelling notification:
public class NotificationHelper {
private static final int NOTIFICATION_ID = 5;
private static NotificationManager mNotificationManager = null;
public static void showNotification(Context context) {
mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.custom_notification_layout);
contentView.setOnClickPendingIntent(R.id.btn_close, closePendingIntent);
Intent mMainIntent = new Intent(context, MainActivity.class);
mMainIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent mMainPendingIntent = PendingIntent.getActivity(context, 555, mMainIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
.setTicker("Playing")
.setContent(contentView)
.setAutoCancel(false)
.setOngoing(true)
.setSmallIcon(R.drawable.ic_av_play)
.setContentIntent(mMainPendingIntent);
Notification notification = mBuilder.build();
mNotificationManager.notify(NOTIFICATION_ID, notification);
}
public static void cancelNotification() {
if (mNotificationManager != null) {
mNotificationManager.cancelAll();
}
}
}
And using that class in your NotificationButtonListener you can call NotificationHelper.cancelNotification(); .
Hope this helps you!

Open a push notification to specific tab on android tab group

I'm new to tabs and push notifications. I want my push notification to open up to a specific tab on my app. I have been able to achieve this, but the tab bar is missing because of the way I have implemented the intent. I'm using the TabActivity to handle the tabs. Is there a way to write the intent so it will open up the app to a certain tab?
private static void generateNotification(Context context, String message) {
int icon = R.drawable.ic_launcher;
long when = System.currentTimeMillis();
String appname = context.getResources().getString(R.string.app_name);
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
int currentapiVersion = android.os.Build.VERSION.SDK_INT;
Notification notification;
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,new Intent(context, FriendGroupActivity.class), 0);
notification = new Notification(icon, message, 0);
notification.setLatestEventInfo(context, appname, message, contentIntent);
notification.flags = Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);
}

When you create the actual Intent you're launching with
new Intent(context, FriendGroupActivity.class)
you should just include more info either in the data URI or extras Bundle, that you then can use in your Activity's onCreate() to switch to the tab you care about

How can I modify a textview from a non-activity class? Android

I want to modify a TextView from an alarmmanager class's onReceive method this class does not extend activity. The alarm sends an intent that creates a notification and I want to make it so clicking the notification will open a textview with a particular string that I get in this onReceive method.
RemoteViews contentView = new RemoteViews(context.getPackageName(),R.layout.notify_layout);
contentView.setTextViewText(R.id.notetext,my_message);
notif.contentView = contentView;
I tried to do this using the RemoteView above with the notification intent but it doesn't seem to work.
I know I can't access this using findViewById, but what approach should I take here?
This is from the code that handles the intent
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.notify_layout);
NotificationManager nm = (NotificationManager)
getSystemService(NOTIFICATION_SERVICE); nm.cancel(getIntent().getExtras().getInt("com.myapp.NotificationDisp"));
Then I have this whole notification thing here. I know that its deprecated and I should be using builder but I need this to be compatible back to gingerbread which it seems builder is not.
Intent i = new Intent("com.MyApp.NotificationDisp");
i.putExtra("com.MyApp.NotificationDisp", 1);
nm = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
#SuppressWarnings("deprecation")
Notification notif = new Notification(R.drawable.ic_launcher,
"Myapp", System.currentTimeMillis());
//
RemoteViews contentView = new RemoteViews(context.getPackageName(),
R.layout.notify_layout);
contentView.setTextViewText(R.id.notetext,
my_message);
notif.contentView = contentView;
PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
i, 0);
notif.contentIntent = contentIntent;
//
notif.setLatestEventInfo(context, "Myapp", my_message, contentIntent);
notif.vibrate = new long[] { 100, 250, 100, 500};
nm.notify(1, notif);
So this brings up a notification with the correct text in my status bar but when I click on it it only shows a blank textview. The xml notify_layout should be setup fine.

How does one animate the Android sync status icon?

I simply want to start and stop the sync icon that is in the status bar. I thought it would be a simple call using NotificationManager, but I cannot find the documentation or sample Q&A on the web or SO.

I found my answer ...
http://libs-for-android.googlecode.com/svn-history/r46/trunk/src/com/google/android/accounts/AbstractSyncService.java
This shows how to set and cancel the stat_notify_sync icon.
private void showNotification(String authority) {
Object service = getSystemService(NOTIFICATION_SERVICE);
NotificationManager notificationManager = (NotificationManager) service;
int icon = android.R.drawable.stat_notify_sync;
String tickerText = null;
long when = 0;
Notification notification = new Notification(icon, tickerText, when);
Context context = this;
CharSequence contentTitle = "mobi"; //createNotificationTitle();
CharSequence contentText = "bob"; //createNotificationText();
PendingIntent contentIntent = createNotificationIntent();
notification.when = System.currentTimeMillis();
notification.flags |= Notification.FLAG_ONGOING_EVENT;
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
notificationManager.notify(mNotificationId, notification);
}
private void cancelNotification() {
Object service = getSystemService(NOTIFICATION_SERVICE);
NotificationManager nm = (NotificationManager) service;
nm.cancel(mNotificationId);
}

To get an animated sync icon you can use android.R.drawable.ic_popup_sync icon. For instance, using the more recent notification builder, you'd use something like:
Notification notification = new NotificationCompat.Builder(mContext)
.setContentTitle("my-title")
.setContentText("Loading...")
.setSmallIcon(android.R.drawable.ic_popup_sync)
.setWhen(System.currentTimeMillis())
.setOngoing(true)
.build();

Thanks for your example, it saved me some time. I created a static method in my Application so I can easily turn the icon on/off from anywhere in my code. I still can't get it to animate though.
In MyApplication.java:
private static Context context;
private static NotificationManager nm;
public void onCreate(){
context = getApplicationContext();
nm = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
...
}
public static void setNetworkIndicator(boolean state) {
if (state == false) {
nm.cancel(NETWORK_ACTIVITY_ID);
return;
}
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, new Intent(), PendingIntent.FLAG_UPDATE_CURRENT);
Notification n = new Notification(android.R.drawable.stat_notify_sync, null, System.currentTimeMillis());
n.setLatestEventInfo(context, "SMR7", "Network Communication", contentIntent);
n.flags |= Notification.FLAG_ONGOING_EVENT;
n.flags |= Notification.FLAG_NO_CLEAR;
nm.notify(NETWORK_ACTIVITY_ID, n);
}
And then from anywhere in my application:
MyApplication.setNetworkIndicator(true);
MyApplication.setNetworkIndicator(false);
