Camera2问题

在6.0.1系统做定制相机开发,调用系统API CameraManager.getCameraList()。获取的cameraId数组为空。事实上设备是有一个摄像头的。为什么会拿不到?请教下是什么原因?有没有其他手段避开这个问题顺利完成相机定制?

在未获取相机权限的情况下,真机上显示了 0Non-removable cameras use integers starting at 0 for their identifiers) 和 1 两个值(前后两个摄像头);
官方文档上显示的是 CameraManager.getCameraIdList(),而不是CameraManager.getCameraList(),
这个 API 是 Android 21 添加的,检查下 targetSdkVersion 是否低于 21。
