MIUI上的相机预览故障（需要帮助MIUI用户/开发人员）
问题描述：
我得到一个眨眼和相机的一个不正确的预览图像（更多详细信息请参阅this问题）。我得到了来自MIUI（Android5-7）用户的类似评论，但是我没有用于测试的MIUI设备。感谢一位用户的帮助，我从他的设备中获得了一条日志。但不幸的是，我无法确定失败的确切原因。MIUI上的相机预览故障（需要帮助MIUI用户/开发人员）

MIUI的用户，您还可以在Google Play测试我的应用程序（请不要留下负面评论）或创建自己的新项目，以检查在什么阶段发生错误。该项目应该：
- 使用android.hardware.Camera（我知道它已被弃用，但我想支持Android 4用户）。
- 使用TextureView输出（I采取在onSurfaceTextureUpdated方法颜色判定的位图。）
我不知道为什么会这样。我希望你能帮助我找出错误的原因。

刚刚在运行MIUI 9 Global的小米MI4（LTE）上测试了您的应用程序7.9.22 | Beta（相应的Android版本：6.0.1 MMB29M）。应用程序运行正常，无闪烁/不正确的图像，以及记录不吐任何相关的错误 下面是logcat的一个片段是这样的：
