Android 模拟器 360 秒后无法启动答案

【问题标题】：Android emulator failed to start after 360 secondsAndroid 模拟器 360 秒后无法启动
【发布时间】：2014-06-27 19:19:52
【问题描述】：

我在运行Ubuntu 14.04 的Macbook Air 上安装了Jenkins 1.568。我安装了 android 模拟器插件，并且我设置的配置在开始每个构建之前以 -no-window 模式运行模拟器。

大约一半的构建很好，但另一半，我在控制台上得到以下信息：

很明显，模拟器有大约 50% 的时间会失败。不过，我不确定为什么，或者如何解决它。欢迎任何关于我如何让它运行而不必使用 naginator 重新启动失败的构建的建议。

【问题讨论】：

问题解决了吗？我面临的情况完全一样
不，抱歉佩德罗。我还没有解决这个问题。我还在等一个答案。同时，如果构建失败，我已经通过再次运行构建（最多 5 次尝试）来缓解它。不是最佳解决方案，但总比让它失败并一直失败要好。
谢谢，我一直在寻找解决方案，但一无所获，所以我用 java 测试构建了一个不依赖于仿真器的模块化事物和另一个仅用于测试的工作，其中我在需要的时候启动它。所以现在我从 jenkins 下载了我的发布版本，唯一不好的是我所有依赖于模拟器的测试用例都必须在不同的工作中启动。如果我找到解决方案，我会发布它！
这个错误再次咬我们。 issues.jenkins-ci.org/browse/… 。请在那里投票和评论
@LyndseyFerguson 我的目标是 android 19.1.0，带有最新版本的构建工具。我使用的 sysimage 是一个模拟器版本，旨在模拟一个 nexus 5（所以 android 4.4.4）。

【解决方案1】：

尝试更新 Java。我过去遇到过 android 模拟器问题，Java 更新修复了这些问题。

【解决方案2】：

超时问题。

DdmPreferences.setTimeOut 是全局 adb 读/写数据包超时设置。在 'at com.android.ddmlib.SyncService.doPushFile(SyncService.java:671)' 中，调用了 DdmPreferences.getTimeOut() 并用于设置超时。

在 build.gradle 中：

android{
...
   adbOptions {
        timeOutInMs 10 * 60 * 1000 // 10 minutes
    }
}

对于 Eclipse（首选项 -> Android -> DDMS）。

此外，这是您在 build.gradle 之外设置的环境变量。例如在 Ubuntu 上：

$ export ADB_INSTALL_TIMEOUT=5
$ ./gradlew installDebug

运行之间：

sudo adb kill-server

和

sudo adb start-server

【解决方案3】：

以下是一份可提供帮助的清单：

1) android list 和 android update sdk 都需要 --all 标志，否则将无法安装某些包：ex for SDK 24

1a)$ANDROID_HOME/tools/android list sdk --all

1b)

(for i in {1..100}; do echo y; sleep 1; done) |
$ANDROID_HOME/tools/android update sdk --no-ui --all --filter 
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,20,21,22,23,24,25,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,79,80,81,82,82,84,85,101,102,103,112,113,117,118,119,120,121,122,123,124

如果您遇到可怕的 /home/jenkins/android-sdk-linux/platform-tools/adb -s emulator-XXXX shell getprop dev.bootcomplete 错误：设备脱机错误，您可能在步骤 1b 中丢失了一个包

2)忽略可怕的 Failed to Initialize backend EGL 显示错误，这是一条红鲱鱼

3)一定要使用高级模拟器选项：

Emulator Options: -no-audio -gpu off
Emulator executable: emulator64-arm
Startup delay: 10  -- this *may* help

4) 预构建脚本${ANDROID_HOME}/platform-tools/adb kill-server 不会受到伤害查看詹金斯网站https://issues.jenkins-ci.org/browse/JENKINS-27456 https://issues.jenkins-ci.org/browse/JENKINS-11952 你也可以检查这个https://code.google.com/p/android/issues/detail?id=209955和http://www.yzjingying.net/4855150152.htm 祝你好运！

【解决方案4】：

我刚刚找到解决方案Android Emulator Plugin Failed to Initialize backend EGL display

将您的作业配置与https://partnerdemo.ci.cloudbees.com/job/Android-dev/job/stockfish-android-cloud/ 进行比较，特别注意以下设置：

Inject env var: LD_LIBRARY_PATH=/opt/android/android-sdk-linux/tool/lib
Target ABI: armeabi-v7a
Advanced -> Emulator Options: -no-audio -gpu off
Advanced -> Emulator Executable: emulator64-arm

希望对你有帮助。

这个答案已经在不同的问题上。配置链接失效。我没有看到我的配置有任何问题。它调用模拟器，但无法启动模拟器
