Question

I’m trying to use custom notifications in my Android application using Google’s sample from here (section Creating a Custom Notification Layout).
Since I’m using this exact code I got a RuntimeException every few times a notification is fired.

My stack trace:

My code:

private final Intent updateInProgressIntent = new Intent(this.context, PodcastListActivity.class);
private RemoteViews updateInProgressContentView = null;
private PendingIntent updateInProgressPendingIntent = null;
private Notification updateInProgressNotification = null;
...
    @Override 
    public void onCreate() { 
        super.onCreate();    
...
        this.updateInProgressPendingIntent = PendingIntent.getActivity(this, UPDATE_INPROGRESS_NOTIFICATION_ID, 
        this.updateInProgressIntent, PendingIntent.FLAG_UPDATE_CURRENT);     
        this.updateInProgressContentView = new RemoteViews(getPackageName(), R.layout.custom_notification);
...
    }

    public void notifyUpdateProgress(final int index, final int size, final Podcast podcast) {

        this.updateInProgressContentView.setImageViewBitmap(
                R.id.image, ActivityHelper.getBitmap(context, podcast.getThumbnailAsset()));
        this.updateInProgressContentView.setTextViewText(R.id.title, "some msg");
        this.updateInProgressContentView.setTextViewText(R.id.text, podcast.getName());
        this.updateInProgressNotification.contentView = this.updateInProgressContentView;       
        this.updateInProgressNotification.contentIntent = this.updateInProgressPendingIntent;               
        this.notificationManager.notify(UPDATE_INPROGRESS_NOTIFICATION_ID, this.updateInProgressNotification);

        ...
        }       

If I replace the custom notification with a standard one (with setLatestEventInfo()) I have no problems.

Ok, so I finally find the solution.

You cannot re-use the same RemoteView object like I did!

I was creating the RemoteView in the onCreate() method, then I was setting its attributes in notifyUpdateProgress().

If I create the object in notifyUpdateProgress() just before using it, I’m not having exception anymore.
