我使用Jenkins构建我的项目之一。Android模拟器插件会自动使用以下配置启动模拟器：
每次作业运行时，都会得到以下输出：
Erasing existing emulator data... $ /ci/home/tools/android-sdk//tools/emulator -no-boot-anim -ports 64470,64471 -prop persist.sys.language=de -prop persist.sys.country=DE -avd hudson_de-DE_240_480x720_Google_Inc._Google_APIs_8 -no-snapshot-load -no-snapshot-save -wipe-data . . shell input keyevent 4 [android] Giving the system some time to settle before creating initial snapshot... $ . . localhost:64471 shell log -p v -t Jenkins "Creating snapshot..." [android] Creating snapshot... $
完整日志如下。
似乎该插件每次都在创建一个新的模拟器，并且不 使用快照。这需要2到4分钟，具体取决于 模拟器的配置。
该插件 在作业文件夹内的.android / avd目录中创建.avd和.ini文件。运行过程之后，不会删除avds。
如果我禁用了使用快照配置，则模拟器需要不到一分钟的时间来 启动。
这是模拟器插件的问题，还是 由于我的配置而无法创建快照？
我希望使用快照可以大大加快我的构建过程。

SDK工具r20中引入 了一个错误 ，试图通过emulator -snapshot-list 命令列出可用的快照会导致崩溃。
由于该命令在未列出可用快照的情况下崩溃了，因此AndroidEmulator Plugin认为不存在现有快照，这会 在每个版本中创建一个新快照。
我发现这些崩溃仅在某些版本的emulator应用程序中发生，即可以避免崩溃。
幸运的是，Jenkins插件使您可以选择emulator要运行的二进制文件。
因此，您可以通过进入作业配置，按下Advanced…仿真器配置并选择“ emulator-arm”（或另一个）二进制文件来解决此问题。
