在禁用了主机GPU的情况下运行Android 5.0.1 x86虚拟设备 [英] Running Android 5.0.1 x86 virtual device with host GPU disabled

问题描述

我正在为我的一个应用程序自动化截图捕获.

I am working on automating screenshots capture for one of my apps.

由于我想捕获一些活动和窗口小部件的屏幕截图，这些活动和窗口小部件会根据系统区域设置而有所不同，因此，我针对每种所需的语言启动了一个新的Android虚拟设备(模拟器)，该虚拟设备具有用于设置系统区域设置的正确属性.然后，使用 uiautomator 模拟特定的用户交互.

Since I want to capture screenshots of some activities and widgets that differ according to the system locale, I start for each desired language a new Android virtual device (emulator) with the correct properties for setting the system locale. Then, specific user interactions are simulated with uiautomator.

我的工作流程按预期工作，但是截图捕获存在问题.实际上，使用 UiDevice.takeScreenshot(File storePath) 或 screencap 在模拟器上始终会创建一个空文件.

My workflow is working as expected but I have an issue with screenshots capture. Indeed, using UiDevice.takeScreenshot(File storePath) or screencap on the emulator always creates an empty file.

运行AVD似乎是一个已知问题启用了主机GPU(我就是这种情况).建议的解决方法是在禁用主机GPU的情况下启动仿真器.不幸的是，当我在禁用Host GPU的情况下启动虚拟设备时，仿真屏幕仍保持黑色.

It seems to be a known issue with AVD running with Host GPU enabled (which is my case). The proposed workaround is to start the emulator with Host GPU disabled. Unfortunately, when I start the virtual device with Host GPU disabled, the emulated screen remains black.

我已经使用-verbose选项和abd -e logcat命令查看了模拟器的输出( logcat输出 >).在logcat输出中，我已经确定了以下错误，但是我无法找出原因:

I have taken a look at the output of the emulator with the -verbose option and abd -e logcat command (emulator output, logcat output). In logcat ouput I have identified the following error but I cannot figure out the cause of it:

E/SurfaceFlinger(  929): hwcomposer module not found
E/SurfaceFlinger(  929): ERROR: failed to open framebuffer (No such file or directory), aborting

下面是我用来启动模拟器的命令:

Below is the command I use to start the emulator:

LD_LIBRARY_PATH=$ANDROID_HOME/tools/lib:$LD_LIBRARY_PATH emulator -avd screenshots -skin nexus_6 \
    -skindir $ANDROID_STUDIO_HOME/plugins/android/lib/device-art-resources -no-audio \
    -prop persist.sys.language=en -prop persist.sys.country=en -verbose -qemu -m 512 -enable-kvm &

我正在使用Nvidia GPU运行Fedora 21.

有人成功启动了具有禁用主机GPU的最新系统映像的Android虚拟设备吗?欢迎任何帮助或建议.

Does someone has succeeded to start an Android virtual device with a recent system image with Host GPU disabled? Any help or suggestion is welcomed.

推荐答案

圣牛！我面临的问题是已知问题.解决方法是使用屏幕分辨率较低的皮肤(例如nexus_4).

Holy cow! The problem I am facing is a known issue. Workaround is to use a skin with lower screen resolution (e.g. nexus_4).
