Emulator
Get the pre-built emulator
- Install android-emulator package in Trusty
- Copy out emulator to read/write directory
- Generate sdcard
- Run the emulator
$ sudo apt-get install android-emulator $ cp -r /usr/share/android/emulator/ ~/ $ cd ~/emulator/ $ ./build-emulator-sdcard.sh $ ./run-emulator.sh
Use the emulator
After starting the emulator with the wrapper script following should be available
- Adb
Emulator will appear in the output of $ adb devices, and will, once fully booted allow
$ adb shell
access into ubuntu.
- Serial console
The terminal where the wrapper script is started from should eventually give one console into Android container
- Telnet access
Once launched graphical window title will show a port number, e.g. 5554. Connect to that over telnet, to send hardware events to the emulator
$ telnet 127.0.0.1 5554 Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'.

Building from scratch
To build
$ sudo apt-get install phablet-tools git bzr $ # install android build-dependencies $ sudo apt-get build-dep android $ # if we're on amd64, we need to pull in certain 32-bit packages explicitly $ sudo apt-get install libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dev:i386 zlib1g-dev:i386 $ # and then work around the fact that libgl1-mesa-dev isn't Multi-Arch: same yet $ sudo ln -s /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1 /usr/lib/x86_64-linux-gnu/libGL.so $ mkdir -p emulator/ $ phablet-dev-bootstrap emulator $ cd emulator $ . ./build/envsetup.sh $ lunch cm_goldfish-eng $ make -j12
To generate sdcard with the ubuntu rootfs
$ ./build/tools/build-emulator-sdcard.sh
Launch emulator with serial console:
$ emulator -verbose -gpu on -system $OUT/system.img -memory 512 -show-kernel -shell -no-jni -qemu -cpu cortex-a8
As of 2013/11/05 there is a bug in the goldfish kernel wrt AppArmor, so you may want to launch with AppArmor disabled until this issue is resolved:
$ emulator -verbose -gpu on -system $OUT/system.img -memory 512 -show-kernel -shell -no-jni -qemu -cpu cortex-a8 -append 'apparmor=0'
You can also use the run-emulator script:
$ ./build/tools/run-emulator.sh
