我正在尝试从Android Studio运行应用程序，但AVD无法启动。它挂在"等待目标设备联机"上，尽管模拟器加载部分已完成(模拟器未打开，但进度条完成(。
从终端输出：

我运行在 Ubuntu 17.04 和 Android Studio 2.3.3 上
我搜索了类似的问题，并试图按照建议启用 adb 集成，但没有成功。
有同样的问题，ubuntu 和 android studio 2.3.3 上的版本，我做的 1 种方式帮助了我，我搜索并最终在 stackoverflow 上找到了解决方案 方法是找到 lib64 文件夹，因为我运行的是 ubuntu 64 位。就我而言，它位于~/Android/Sdk/emulator/lib64下并运行命令终端：
首先在终端中编写以下命令
$ sudo apt-get install lib64stdc++6：i386
$ sudo apt-get install mesa-utils
导航到 ~/Android/Sdk/emulator/lib64 文件夹
$ mv libstdc++/libstdc++.bak
$ ln -s/usr/lib64/libstdc++.so.6 libstdc++
