I hope this helps you . The problem I am facing is :
I allocate some Bitmaps in my UIthread. System doesn't free the memory if you press the BACK button.
code :
protected void onPause()
{
    super.onPause();
    System.gc();
}

I wish this help you You can pause your application (by pushing the Home button, simulating a call, whatever). Then kill the app's process through adb. Since the docs say that after onPause() returns your app can be killed without any further notice, this is a fair test.
If you don't want to go through the trouble of finding the pid of your app's process, you can use adb shell am kill com.example.package_name to kill your app's process. Make sure that the app is put in the background. The docs say that this command "kills only processes that are safe to kill and that will not impact the user experience." So you might want to launch a couple of other apps before trying this one.

this one helps. It's unlikely that your runnables consumes so much memory. Each runnable instance should be cleared by GC after it is processed. If you are creating and posting runnables faster then they are executed you would get ANR because your UI thread wouldn't be able to dispatch input events. If you create new runnables often it will cause GC to trigger more often but your heap shouldn't grow.
It's more likely that you have memory leaks in your app. You can use MAT to check what exactly consumes a lot of memory in java heap.

This might help you There's a section called Apps in the Developer options. Make sure Do not keep activities is on, it'll allow you to test this behavior. Just don't forget to turn it off when you're done or you will be debugging weird lifecycle behavior in your app later.
