但当Camera横竖切换时程序运行起来时，抛出如下异常：
android.app.SuperNotCalledException: Activity Camera did not call through to super.onConfigurationChanged()
分析了Android2.3 Camera源码后，是由于在调用重写onConfigurationChanged未立即调用父类方法导致。
public void onConfigurationChanged(Configuration config) {
super.onConfigurationChanged(config);//这个出了问题，必须在重写后立即调用。
Log.e(TAG, "onConfigurationChanged() config="+config.toString());
PreviewFrameLayout frameLayout =
(PreviewFrameLayout) findViewById(R.id.frame_layout);
frameLayout.setWindowOrientation(config.orientation);
if(config.orientation == WINDOW_ORIENTATION_HORIZENTAL){
if (!mPreviewing && !mStartPreviewFail) {
Log.e(TAG, "!mPreviewing && !mStartPreviewFail onConfigurationChanged");
// resetExposureCompensation();
if (!restartPreview()) return;
}
changeHeadUpDisplayState();
if(!isBusyingNow){
Animation a = mShowZoomBarAnimation;
a.setDuration(300);
rootView.startAnimation(a);
rootView.setVisibility(View.VISIBLE);
}
isScreenLocked=false;
}
// super.onConfigurationChanged(config);//这个出了问题，必须在重写后立即调用，注释掉，然后移动到方法开始。
}
LOG如下：
