Android: How to solve Bitmap java.lang.OutOfMemoryError?

Question

I'm getting java.lang.OutOfMemoryError when using bitmap to show large images.
For resizing the bitmap, I referred following link Save Bitmap and BitmapFactory.decodeFile.

My logcat is as follows:

Since you have not posted your code it is hard to know whether there is a bug or probably ineffective code that can be improved.

But generally the JVM memory is limited, so loading of big image can cause OutOfMemoryError. You can try to increase the JVM memory using -Xmx option. This is the first and the simplest way.

Other way is to decrease your image (if it is possible). Or probably use format other than BMP (e.g. JPG). It guarantees good quality and requires less memory.
