Docker Gitlab错误运行Android Emulator:无法决定主机位.假定32位

Question

我正在尝试自动化Android构建和测试。仪器测试由于我在docker Runner中启动Android Emulator 时会遇到以下错误：

Running with gitlab-ci-multi-runner 9.4.2 (6d06f2e) ...
Using Docker executor with image kmindi/android-ci:latest ...
...
$ chmod +x ./gradlew
$ echo no | avdmanager -v create avd --force --name test --abi google_apis/x86_64 --package 'system-images;android-25;google_apis;x86_64'
Do you wish to create a custom hardware profile? [no] $ export SHELL=/bin/bash && echo "no" | emulator -avd test -noaudio -no-window -gpu off -verbose -qemu
sh: 1: file: not found
sh: 1: file: not found
WARNING: Cannot decide host bitness because $SHELL is not properly defined; 32 bits assumed.
ERROR: 32-bit Linux Android emulator binaries are DEPRECATED, to use them
    you will have to do at least one of the following:
    - Use the '-force-32bit' option when invoking 'emulator'.
    - Set ANDROID_EMULATOR_FORCE_32BIT to 'true' in your environment.
    Either one will allow you to use the 32-bit binaries, but please be
    aware that these will disappear in a future Android SDK release.
    Consider moving to a 64-bit Linux system before that happens.

我创建了以下dockerfile（https://hub.docker.com/r/kmindi/kmindi/android-ci/）

https://stackoverflow.com/a/37604675/455578（bash/sh的chaning）在https://stackoverflow.com/a/a/37604675/455578中提出的解决方法不起作用（在Dockerfile中应用）。还设置壳变量也无济于事。如果我使用emulator64-x86代替emulator，则会获得错误command not found。

我缺少什么？

我必须通过APT安装其他软件包吗？

也许它起源于二手OpenJDK-8/Debian Stretch Docker Image？

谢谢：）

Answer 1

带有SDK修订版25.3.0（2017年3月）的模拟器与SDK工具分开发布（https://developer.android.android.com/studio/releases/releases/emulator.html#25--25--25--25--3）。

实际上，这意味着现在有一个新的${ANDROID_HOME}/emulator文件夹，您必须添加到路径中。（注意：必须在工具文件夹之前添加，因为无论出于何种原因，旧的tools/emulator仍然存在）。示例：

ENV PATH ${ANDROID_HOME}/emulator:${ANDROID_HOME}/tools:${ANDROID_HOME}/tools/bin:${ANDROID_HOME}/platform-tools:${PATH}
