android - 为什么 Jenkins Android 模拟器插件会在每个构建中重新创建我的模拟器快照？

我使用 Jenkins 来构建我的一个项目。 Android Emulator Plugin 会自动启动具有以下配置的模拟器:

emulator configuration

模拟器插件的配置:

emulator plugin configuration .

每次作业运行时，我都会得到以下输出:

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... $

下面的完整日志。

插件似乎每次都在创建一个新的模拟器，并且没有使用快照。这需要 2 到 4 分钟，具体取决于模拟器配置。

插件在作业文件夹内的 .android/avd 目录中创建 .avd 和 .ini 文件。运行过程后avds不会被删除。

如果我禁用使用快照配置，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，还是因为我的配置无法创建快照？

我希望使用快照能大大加快我的构建过程。

最佳答案

一个 bug was introduced在 SDK Tools r20 中，尝试列出可用快照(通过 emulator -snapshot-list 命令)会导致崩溃。

由于该命令在未列出可用快照的情况下崩溃，Android Emulator Plugin 认为没有现有快照，这会导致在每个构建中创建一个新快照。

我发现这些崩溃只发生在 certain versions 上。 emulator 应用程序，即可以避免崩溃。

幸运的是，Jenkins 插件允许您选择要运行的 emulator 二进制文件。

因此，您可以通过进入作业配置、在模拟器配置中按 Advanced… 并选择“emulator-arm”(或其他)来解决此问题二进制。
