    - by RankoR
    I'm getting drawing cache of the view, that is set as contentView to the Activity. Then I set new content view to the activity and pass that drawing cache to it. But Android recycles my bitmaps and I'm getting this exception: 06-13 01:58:04.132: E/AndroidRuntime(15106): java.lang.RuntimeException: Canvas: trying to use a recycled bitmap android.graphics.Bitmap@40e72dd8 Any way to fix it?
