横屏扫描问题 about android-zxing

[yangy996]

有个办法可以解决下，在androidmanifast中加入这条语句 android:configChanges="screenSize|keyboardHidden|orientation"
但又出现另一个问题，解锁过快，扫描界面会崩掉。。。

[mylhyl]

扫描页面生命周期是否加入

 @Override
    protected void onResume() {
        mScannerView.onResume();
        resetStatusView();
        super.onResume();
    }

    @Override
    protected void onPause() {
        mScannerView.onPause();
        super.onPause();
    }

可参考https://github.com/mylhyl/Android-Zxing/blob/master/sample/src/main/java/com/mylhyl/zxing/scanner/sample/ScannerActivity.java

只是扫描界面崩溃，这个日志有点看不懂
