在Ubuntu 17.04上从Android Studio运行AVD

Question

我试图在Android Studio中运行一个应用程序，但是AVD没有启动。 虽然模拟器加载部分完成（模拟器没有打开，但进度条完成），但它卡在“等待目标设备上线”的状态。

终端输出：

[Idea.Log]

我正在运行 Ubuntu 17.04 和 Android Studio 2.3.3。

我搜索了类似的问题，并尝试根据建议启用了 adb 集成，但没有成功。

你能添加你的 idea.log 尾部吗？它在 ~/.AndroidStudioPreview3.0/system 上。 - Martin Revert

我的第一个猜测是你的项目针对的是API 19，而该API级别不适用于即时运行构建。我建议将minSdkVersion升级到21并使用相匹配的API模拟器。如果由于任何原因无法实现这一点，则可以从“文件”->“设置”->“构建、执行和部署”->“即时运行”中禁用“即时运行”，重新启动Android Studio，然后再次尝试。 - Martin Revert

同样失败了，下载了ARM x64 API 24（我使用的是AMD CPU）的镜像，但没有成功。:/ https://pastebin.com/eAWZqNsV (idea.log) - Brian

日志在模拟器非常开始时停止，没有错误和即时运行错误消息，这很好。现在问题是另一件事，也许与NDK依赖项有关，但没有错误证明这一点。很抱歉，我无法从这里提供帮助。 - Martin Revert

Answer 1

我遇到了同样的问题，使用的是ubuntu和android studio 2.3.3版本。我找到了一个方法来解决它，通过在stackoverflow上搜索，最终找到了解决方案。

解决方法是找到lib64文件夹，因为我使用64位的ubuntu。在我的情况下，它位于~/Android/Sdk/emulator/lib64文件夹下，然后在终端中运行以下命令：

//首先在终端中输入以下命令

$ 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++
