I just have a scenario where catching an OutOfMemoryError seems to make sense and seems to work.

Scenario: in an Android App, I want to display multiple bitmaps in highest possible resolution, and I want to be able to zoom them fluently.

Because of fluent zooming, I want to have the bitmaps in memory. However, Android has limitations in memory which are device dependent and which are hard to control.

In this situation, there may be OutOfMemoryError while reading the bitmap. Here, it helps if I catch it and then continue with lower resolution.
