Gluon CompleteableFuture在设备上拒绝不安全访问

Question

我最初编写了一个名为backendMethodCall的函数来使用旧的python WSGI网关。一切正常，直到我决定检查胶子为Android移动设备开发一些东西。我在桌面上测试时使用代码成功调用远程服务器，但是当我使用androidInstall任务将应用程序安装到我的Android设备（LG G4,6.0）上并拨打电话时，应用程序崩溃。

我使用adb logcat > test_log来获取以下错误：

我不确定为什么会这样。我最初的想法是代码需要一些权限才能运行，但我没有看到任何可能的许可的迹象。
