Question

I have written a small Android project that shows some (image)buttons. It works fine on my phone ( Galaxy S ), but when I try to run it on emulator, it gives the following error:
Caused by: java.lang.OutOfMemoryError: bitmap size exceeds VM budget

Please note, first activity, has 8 image buttons, and it gives out of memory exception. When I remove 3 buttons, it works fine. Actually, it works fine as long as scrollView is inivisble and If I add those 3 removed buttons ( so, scrollView is going to be visible ), it gives out of memory error. I think, this “out of memory” exception is not related to the number of (image) buttons, but is related to background image. Here is my XML file:

Would you please help me?

Your running low on memory, and the best way to remedy that will be to use less memory, loading smaller images will help a great deal here, and googles android team have been kind enough to put up a short description on how to do this 🙂
