I’m still alive, even if nothing here has been updated in a while.

Today I’ve got some notes about Android Virtual Devices…

Running AVD emulator from the Windows command line/Powershell/mingw32

This assumes you’ve got Android Studio installed.

First you need to have the tools path in your $PATH variable, to do this edit Path in Windows’ Environment variables to include for example:

C:\Users\Max\AppData\Local\Android\Sdk\tools

Then you can use emulator.exe from anywhere. The Android Studio docs fail to mention this.

$ emulator -no-boot-anim -accel auto -writable-system -no-snapshot -gpu host -avd K10_API_22

Installing Google Play Services

I’ve been messing around with older device profiles, and trying to run things in Chrome on Android 5.0 (API level 21).

You’ll need to sideload the Google Play services system APKs (from a gapps package for your target system, e.g. https://androidhost.org/BcyG7), but you might find that the /system partition is full.

No problem, you can sideload to /sdcard and symlink:

$ adb remount
# Fails...
$ adb push .\GmsCore.apk /system/priv-app
$ adb: error: failed to copy '.\GmsCore.apk' to '/system/priv-app/GmsCore.apk': No space left on device

# Works...
$ adb push .\GmsCore.apk /sdcard/system/priv-app
$ adb push .\GoogleLoginService.apk /sdcard/system/priv-app
$ adb push .\GoogleServicesFramework.apk /sdcard/system/priv-app
$ adb push .\Phonesky.apk /sdcard/system/priv-app

# Symlink them
$ adb shell ln -s /sdcard/system/priv-app/GmsCore.apk /system/priv-app/GmsCore.apk
$ adb shell ln -s /sdcard/system/priv-app/GoogleLoginService.apk /system/priv-app/GoogleLoginService.apk
$ adb shell ln -s /sdcard/system/priv-app/GoogleServicesFramework.apk /system/priv-app/GoogleServicesFramework.apk
$ adb shell ln -s /sdcard/system/priv-app/Phonesky.apk /system/priv-app/Phonesky.apk
$ adb shell stop
$ adb shell start

Messing around with /etc/hosts

It’s trivial to edit the /etc/hosts on your AVD, but it only works if you have blank new line at the end of the hosts file.

$ adb pull /etc/hosts hosts
$ nano hosts # make your changes to the hosts file locally...
$ adb push hosts /etc/hosts
