做了Android摄像头编程的测试，自己总结一下代码和其中的注意事项。

CameraTestActivity.java：

                       MainActivity  Activity        String Tag = "CameraTest"                                                                                     WindowManager wm =         Display display =                  screenWidth =         screenHeight =                  mSurfaceView =         mSurfaceHolder =          mSurfaceHolder.addCallback(                           Log.d(Tag, "resume"                               Log.d(Tag, "pause"                               Log.d(Tag, "stop"                               Log.d(Tag, "destroy"                      Log.d(Tag, "surface created"         mCamera =          (mCamera ==              Log.d(Tag, "camera null"                    }              Log.e(Tag, "IOException caused by setPreviewDisplay"           Camera.Parameters parameters =                   (.getResources().getConfiguration().orientation ==             parameters.set("orientation", "portrait"             mCamera.setDisplayOrientation(90         }              parameters.set("orientation", "landscape"             mCamera.setDisplayOrientation(0           previewWidth = 0          previewHeight = 0         List<Camera.Size> previewSizes =         Iterator<Camera.Size> iter =                      Camera.Size size =             Log.d(Tag, "" + size.width + " by " +              (size.width >= previewWidth && size.width <= screenHeight &&                     size.height >= previewHeight && size.height <= screenWidth) {                 previewWidth =                 previewHeight =            Log.d(Tag, "preivewWidth: " + previewWidth + " preivewHeight: " +         List<String> focusModes =          (focusModes !=  &&            previewSize =              surfaceChanged(SurfaceHolder holder,  format,  width,          Log.d(Tag, "surface changed"                                    mSurfaceView.setLayoutParams( LinearLayout.LayoutParams(width, ()(width * previewSize.width /                                 Log.d(Tag, "surface destroyed"          (mCamera !=              mCamera.autoFocus(              mCamera.setPreviewCallback(              mCamera =             Camera.AutoFocusCallback mAutoFocusCallback =             onAutoFocus(             Log.d(Tag, "AutoFocus: " +                                                            }                                Camera.PreviewCallback mPreviewCallback =             onPreviewFrame(                      }
