Answer 1

Try using the sampleSize of BitmapFactory.Options, this will reduce the size in memory of your image (and the quality)

But if your image is really too big, I think that's there no miracle solution, the image is simply too big...

Answer 2

Your problem is exactly what stated in error message: your image is too big to be loaded into memory.

Answer 3

Try with any other image. As this image is exceding the size of ur folder.

R u using Emulator to test it?

Answer 4

Just a idea, it could be this piece of code throws sometime a exception. This will causes that the InputStream will not release rthe asigned resources (memory leak).

if you close the Input stream in a finaly block this issue should be solved
