如何在没有OOM（内存不足）异常的情况下进行屏幕捕获？

Question

I want to screencapture and save a view.

I think I can create a bitmap as big as the view and draw the view on this bitmap. In this situation, the view's width is the same as the screen's width, and its height may be more than the screen.

So it is easy to get an OOM problem. Is there any way to avoid this problem?

Answer 1

If you don't need transparency, you can use Bitmap.Config.RGB_565 instead of Bitmap.Config.ARGB_8888 :

Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);

This reduces memory usage by half.
