  1. POrunOnUiThread stops Working When Application is Destroyed
    text
    copied!<p>So here's what happening: I'm using the runOnUiThread() method to change an Image View from another class when that class receives a message from another phone. I'm calling it by using mainclass.runOnUiThread(new Runnable...) and so on. It works the first time the application is run, but when I hit the back button to exit the application, and then launch the application again, the Image View no longer updates. The logs I took shows me that everything is fine and being run, but the Image View doesn't change. I don't get any errors and it doesn't crash when I run the application, it just doesn't update the Image View. Any idea what might be causing this?</p> <p>Edit*: So this is what i'm actually using to change the imageView in a class that doesn't extend Activity</p> <pre><code>peerActivity.runOnUiThread( new Runnable(){ @Override public void run() { Log.v("Thread@", "Thread is running"); Log.v("Thread@2", decodedImage.toString()); // TODO Auto-generated method stub peerActivity.ivPhoto.setImageBitmap(decodedImage); Log.v("Thread@3", "Past UI Change"); } }); </code></pre> <p>Where peerActivity holds the other class reference and ivPHoto is the Image View. What I think I need to do is find a way to kill that thread when the program closes (when I go into the program manager, it still has the Force Close button available). Is there any way to do this?</p> <p>Edit2*: So I tried a bunch of different approaches to working on the UI Thread and they all give me the same result: The program works perfectly the first time its run but when I hit the back button and close it and the re-open it, the Image View no longer updates. If I force close the app, it works fine again until I close it and re-open it.</p>
