使用CLI并使用以下命令运行模拟器：
./emulator -use-system-libs @Nexus5API25
仅显示错误，模拟器无法启动。
emulator: ERROR: There's another emulator instance running with the current AVD 'Nexus5API25'. Exiting...
和
当使用-verbose执行时，会打印更多详细信息，但我没有看到任何可以帮助我解决问题的内容：

我知道我可以删除AVD并创建新的AVD。但有没有办法解决现有AVD的问题，而无需重新创建它？
答案 0 :(得分：62)
我设法通过删除由avd manager创建的锁定文件来解决问题。
rm ~/.android/avd/Nexus_5_API_25.avd/hardware-qemu.ini.lock
删除文件后，模拟器一直运行正常。
答案 1 :(得分：2)
在Linux中，它也可能是由root创建的AVD引起的，而另一个用户试图运行模拟器。在这种情况下，更改avd文件夹内容的所有者应该有助于解决它。
null答案 2 :(得分：1)
即使没有其他模拟器正在运行，我也遇到了同样的问题。
在我的例子中，保存avd目录的文件系统是只读的。重新安装它rw解决了问题
mount -o remount,rw /path/to/avd/file/system

您是否曾尝试在运行脚本之前终止该进程？
首先找到PID
adb shell ps
然后你杀了进程
adb shell kill <PID>
