<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.FLASHLIGHT" />

public void surfaceDestroyed(SurfaceHolder holder) 
    {
        /* 停止预览 */
        mCamera.stopPreview();
        mCamera.release();
        mCamera = null;
    }

Canvas canvas = null;
try {
mHolder = getHolder();
canvas= mHolder.lockCanvas();
canvas.drawBitmap(CameraBitmap, 0, 0, null);
mHolder.unlockCanvasAndPost(canvas);
} catch (Exception e) {
if(canvas!=null){
mHolder.unlockCanvasAndPost(canvas);
}
}
