当我尝试使用“CREATE liVE EVENT”按钮创建事件时.它会抛出一些跟随错误.我认为这是由于相机许可问题而发生的.

错误：

任何人请建议.我该如何解决这个问题.

解决方法 在调用发生的活动代码中,用一个检查包装它：

int hasCamPermission = checkSelfPermission(cameraPermission);int hasMicPermission = checkSelfPermission(microphonePermission);

首先将以下方法添加到StreamerActivity：

private boolean shouldCheckForPermission() {  return Build.VERSION.SDK_INT >= Build.VERSION_CODES.M;}

将这些行更改为：

int hasCamPermission = shouldCheckForPermission() ? checkSelfPermission(cameraPermission) : PackageManager.PERMISSION_GRANTED;int hasMicPermission = shouldCheckForPermission() ? checkSelfPermission(microphonePermission) : PackageManager.PERMISSION_GRANTED;

为此,您需要使用SDK 23进行编译和定位,如上面的答案中所述.
