Hey all- I'm fairly new to Android development and Java development and I've discovered that an app I created recently has a serious memory leak issues.
Due to the nature of this app, potentially Activities could be added to the stack ad infinitum. To make matters worse, every activity downloads a lot of images from web feeds. I have read a lot about bitmaps leaking in android and have implemented many suggestions from the web about how to release these explicitly. I'm mainly doing this in the onStop override for each Activity. It seems that I still have a lot of leaking going on, I have some lines of code tracking the memory build up as I go. I have a few pointed questions about what I'm doing that I'm hoping getting answers to will correct my understanding and my code: 1.) My understanding is that if an object (an Activity in this case) is holding objects, upon being destroyed the memory for those objects should also marked for GC as long as nothing else is holding a reference to it. Is that correct? Because of that, I have been using the current Activity as the context for any Adapters I instantiate as well, assuming that would pair the Adapters and any views they are holding with the Activities lifecycle. Is that more or less correct? 2.) If I start another activity from the current activity, what context should I pass to the constructor of Intent? Currently I've been either using the current activity instance, or the view who's onclicklistener has been triggered. 3.) If I set a reference to a new object, the previous object it held should be ready for GC, assuming nothing else is holding it, correct? Any other thoughts or ideas around my problems would be appreciated as well. I have been finding the DDMS tool to be difficult to use to trace back leaks to their origins.
