我得到一个眨眼和不正确的相机预览图像（有关更多详细信息，请参阅此问题）。我从 MIUI (Android 5-7) 用户那里得到了类似的评论，但我没有带有 MIUI 的设备进行测试。感谢一位用户的帮助，我从他的设备中获得了一份日志。但是，不幸的是，我无法确定失败的确切原因。

MIUI 用户，您也可以在Google Play中测试我的应用程序（请不要留下差评）或创建自己的新项目以检查错误发生在哪个阶段。该项目应：

  • 使用 android.hardware.Camera （我知道它已被弃用，但我想支持 android 4 上的用户）。
  • 使用 TextureView 进行输出（我在 onSurfaceTextureUpdated 方法中使用位图来确定颜色。）

我不知道为什么会这样。我希望您能帮助我确定错误的原因。

刚刚在运行 MIUI 9 Global 7.9.22 的小米 MI4 (LTE) 上测试了您的应用程序 | Beta（对应安卓版本：6.0.1 MMB29M）。应用程序运行良好，没有闪烁/不正确的图像，并且日志没有吐出任何相关错误这是 logcat 的片段：
