更新

我正在开发一个需要相机许可的小型应用程序。我可以处理运行时权限，但真正的问题是，当我中继到Sinchpayload并进入来电活动时。此活动应请求权限（相机和其他2个权限）。但是，由于没有安全例外，它没有显示权限对话框，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-不会发生其他权限，并且仅在带有相机“ 2” Api的Android 9上运行-Android 8.1及更低版本可以正常使用。 此问题仍然发生在示例采样推上。权限对话框将显示是否像往常一样启动活动。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();

Answer 1

应用程序权限对话框仅显示在前景中。
