Application Will Crash When Taking Multiple Photos One After Another

[vigen-b]

Android system will throw error if yo try to take picture after stopPreview(). To decide take or don't take picture you are using mIsCapturing boolean which you change without synchronization with startPreview and stopPreview (see onShutter callback). This will throw error if you try to take picture multiple times one after another without short pause.
