Answer 1

It depends how big your bitmap is, Android seems to allocate a little more space than the size of the image when you read the size on your computer. So...

• You could just use a smaller image.
• Google have actually published a guide on avoiding OutOfMemoryErrors here which will help a lot, though I had to use a smaller image size as well.
• One method that will almost definitely work is to set android:largeHeap="true" in your manifest, between your application tags. This will increase your heap size, but may make your app lag a little.

Maybe for you, a combination of these ideas will work.
