Re: [android-developers] Re: Home screed Widget crash
Thank you guys. I fixed it without using the alarm manager :) . What i was doing wrong is that i was creating bitmaps and sending them off to be displayed on the remote widget, thinking that it's memory would be reclaimed when the next image takes its place. Apparently, this wasn't happening. So i limited the scope of creation of the remoteViews to the function in which the widget was updated each time, downloaded images within the same scope and it works like a charm :) no memory issues now.
