Android Memory Leaks Issue

Question

I was experiencing a memory leak problem with one of my apps, and after many hours, I instead decided to create a new project as a dumbed down version of the app:

• The app contains 2 activites
• The first page xml has 3 ImageViews with src and formatting. The code listens for clicks on one of those and opens a new activity (second activity).
• The second just has 2 ImageViews and 2 EditTexts. The .java does nothing
• I only have 4 images in drawable
• It's a new project with only these two added activities and a new style (just made it full screen)

The problem:

• Clicking on the listend-to ImageView gives an OOM exception.
• the heap size is about 45 MB, 91% full

More Details:

• I tried Memory Analyzer. I only have 1 instance of my class. The problem suspects (1 & 2 which account > 75%) is byte[] loaded by <system class loader>
• I also found the Error 'A resource was acquired at attached stack trace but never released' in my Log, which makes no sense based on the above.

I've spent all day on this, and created countless new projects just to test it, and I'm still lost. I know most people can't provide an answer based on the given information, but if you can tell me the next steps, or some things to try to figure out the problem, that counts as an answer too.

Answer 1

Add in your AppManifest.xml in your application tag this code:

android:largeHeap="true"

This will try to prevent your app from causing OutOfMemoryError.

Documentation: http://developer.android.com/guide/topics/manifest/application-element.html#largeHeap

Although this is not a very recommended solution, it should still work...

You can also try to decrease your images' resolution if they are so large.
