"[android]模拟器似乎没有开始;放弃"

Question

Jenkins无法启动模拟器.这是jenkins的控制台输出:

First time build. Skipping changelog.

如果我输入

/usr/local/android-sdk/tools/emulator -snapshot-list -no-window -avd hudson_en-US_160_WXGA720_android-15_x86

要么

/usr/local/android-sdk/tools/emulator -no-boot-anim -ports 60491,34583 -prop persist.sys.language=en -prop persist.sys.country=US -avd hudson_en-US_160_WXGA720_android-15_x86 -no-snapshot-load -no-snapshot-save -wipe-data

我明白了

PANIC: Could not open: hudson_en-US_160_WXGA720_android-15_x86

我在ubuntu 12.04上运行jenkins.

错误"SDL init failure,原因是:没有可用的视频设备"表明模拟器未在图形环境中运行.

然而,你的日志显示,VNC服务器是正在启动.但也许VNC服务器在仿真器启动时还没有完全启动.

您可以通过将模拟器启动延迟几秒来检查是否是这种情况.

从Android Emulator插件文档:

虽然Android Emulator插件的设计是为了确保它始终在Xvnc服务器启动后运行,但Xvnc插件不会等待Xvnc服务器完全启动并运行,然后再将控制权交给Android Emulator插件.

出于这个原因,您可能希望将模拟器启动延迟几秒钟(例如三到五秒),从而使Xvnc服务器有时间在尝试启动Android模拟器之前完成启动.为此,请在"高级"选项下的"启动延迟"字段中输入所需的秒数.

或者,您可以取消作业配置中的"显示仿真器窗口"选项,该选项不会显示仿真器,并且无需运行VNC服务器.
