The problem is because your bitmap's size is too large than the VM can handle. For example from your code I can see that you are trying to paste an Image into imageView which you are capturing using Camera. So normally the camera images will be too large in size which will rise this error obviously.
So as others have suggested, you have to compress your image either by sampling it or convert your image into smaller resolution.
For example if your imageView is 100x100 in width and height, you can create a scaled bitmap so that your imageView gets filled exactly. You can do this for that,
Bitmap newImage = Bitmap.createScaledBitmap(bm, 350, 300,true);
or you can sample it in methods what user hotveryspicy have suggested.
