camera在切换前后摄像头时的异常
Process: com.test.wrapper, PID: 8923
java.lang.RuntimeException: Camera is being used after Camera.release() was called
at android.hardware.Camera.setHasPreviewCallback(Native Method)
at android.hardware.Camera.-wrap1(Unknown Source:0)
at android.hardware.Camera$EventHandler.handleMessage(Camera.java:1237)
at android.os.Handler.dispatchMessage(Handler.java:105)

at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:782)
原因:
缺少mCamera?.setPreviewCallback(null)
果然调试代码时候还是要小心翼翼点儿啊...
mCamera?.stopPreview()
mCamera?.setPreviewDisplay(null)
mCamera?.setPreviewCallback(null)
mCamera?.lock()
mCamera?.release()
mCamera = null
