Jenkins Android Emulator error: device 'localhost:7903' not found (the emulator starts but the connection to it fails)

Question

I have installed Jenkins with Android Emulator Plugin on my MacMini. But emulator does not work:

Here is the log:

[android] Starting Android emulator

The filesystem is already 51200 (4k) blocks long.  Nothing to do!

I have tried different emulators (API level 15,16,17,18,19,20). I have also tried different Android Emulator Plugin-Versions (2.13.1 and 2.10). Nothing seems to work. Please help.

Answer 1

Android emulator plugin中的{p> Jenkins非常稳定（可能是插件问题或我的Jenkins构建机器）。我发现有一种配置对我有用。

这是日志中的行（与您的行比较）： $/backup/android-sdk-linux/tools/emulator -ports 7379,7380 -prop persist.sys.language=en -prop persist.sys.country=US -avd hudson_en-US_160_WXGA800_android-17_x86_namshi -no-snapshot-load -no-snapshot-save -no-window -no-boot-anim -noaudio -verbose

这里的工作模拟器配置如何：

我的建议是使用不同的配置并找到一个稳定的。此外，如果端口繁忙，请尝试重新启动Jenkins计算机，看看它是否有帮助。

感谢您的帮助。在我的情况下，解决方案是将android模拟器插件降级到版本2.12。最新版本（2.13.1）在我的案例中不起作用。
