Hi ,
I get an issue when i am adding switch camera function in RtcActivity.java
java.lang.RuntimeException: Fail to connect to camera service
at android.hardware.Camera.(Camera.java:545)
at android.hardware.Camera.open(Camera.java:385)

videoCapturerAndroid.switchCamera(new Runnable() {
        @Override
        public void run() {
        }
    }); // or  videoCapturerAndroid.switchCamera(null);

这两种方式都是可以的，需要注意videoCapturerAndroid 为全局唯一变量
