java - Android pei 的sinch视频通话摄像头权限问题(9)

Question

更新

我正在开发一个需要相机权限的小应用程序。我可以处理运行时权限，但真正的问题是当我中继到 Sinchpayload 并转到传入调用 Activity 时。此 Activity 应请求权限(相机和其他 2 个权限)。但它没有显示权限对话框，而是由于安全异常而使我的应用程序崩溃。 仅当我请求相机权限时才会发生这种情况 - 其他权限不会发生这种情况，并且仅在具有相机“2”Api 的 Android 9 上 - Android 8.1 及更低版本工作正常 。 使用 SINCH 示例推送时仍然会出现此问题。权限对话框将显示是否像往常一样有意开始 Activity 。这是错误:

这是我请求权限的代码:

if (Build.VERSION.SDK_INT>=23)
    {
 if (GlobalConstants.isAllPermissionsGrantedBefore_Video_Call(this)==false)
            ActivityCompat.requestPermissions(
                    Video_incomming_call.this,
                   GlobalConstants.mPermissions_Video_Chat,
                    GlobalConstants.VIDEO_RECIEVE_CODE);
        else {
            Start_Calling();
        }

    } else Start_Calling();

应用程序权限对话框仅显示在前台。
