Avoid drawing objects allocation during drawing operations

[00conan00]

Dear developers,
My analysis tool have found another issue. I found drawing object creation in storymaker's code. It could make UI appear sluggish.

As suggested by Android Developers,"Creating objects ahead of time is an important optimization. Views are redrawn very frequently, and many drawing objects require expensive initialization. Creating drawing objects within your onDraw() method significantly reduces performance and can make your UI appear sluggish."

We found the violations in this class:

Class name: info.guardianproject.mrapp.ui.BigImageLabelView
--Handler name: info.guardianproject.mrapp.ui.BigImageLabelView.onDraw(Landroid/graphics/Canvas;)V
--Avoid expensive drawing objects allocations during draw operations(preallocate and reuse instead):
----android.graphics.Rect.(IIII)V

The call hierarchy is as follows:
onDraw();
computeBounds();
