corwin42 Expert Licensed User Longtime User Jun 28, 2012 #1 [Solved] Setting images for widget with many imageviews I have a homescreen widget with some imageviews. Updating the images does not work reliably. This took me some time to find out what's the problem so I could create a test project. If you run the test project (at least on my device) the images are not displayed in the widget. In the unfiltered log I can see the message "!!! FAILED BINDER TRANSACTION !!!" If I update just one image it works. If I call rv.UpdateWidget after setting the image it works better but still some images won't display. When the problem occurs even the Panel1_Click event does not fire anymore. Any ideas? Attachments WidgetBug.zip WidgetBug.zip 56.8 KB · Views: 491 Last edited: Jun 28, 2012

corwin42 Expert Licensed User Longtime User Jun 28, 2012 #3 The strange thing is that it worked some time ago. I have reworked my weather app completely and now I wanted to reactivate the widget and got the problem. I used the old layout file and the old code. The only thing I changed was the data structure with the weather data and that I now use caching for the images so that not every bitmap is loaded again for each image. ... Ah, and I changed the image files. They now are 256x256 pixel in size instead of 128x128. I will try to use LoadBitmapSample instead with the size I need. Thanks for the info. With this I can hopefully fix the issue in my app.
