I’ve installed android on my freerunner. I’ve to say that it works ! very nice and functional interface, finger friendly, voice, sms, wifi work out of the box. I’m very impressed.
Following the lead from http://lackingrhoticity.blogspot.com/2010/02/how-to-build-adb-android-debugger.html I’ve decided to build adb to connect to my phone without downloading the precompiled sdk and without checking-out the entire android git repository. It’s actually very easy, and I’m sure with a minimal effort, it should be possible to create a debian package. The android instructions give some hints regarding the cross-compilation of android on a x64 machine.
Cutting and pasting from Lacking Rhoticity blog you need to :
$ sudo apt-get install build-essential libncurses5-dev
$ git clone git://android.git.kernel.org/platform/system/core.git system/core
$ git clone git://android.git.kernel.org/platform/build.git build
$ git clone git://android.git.kernel.org/platform/external/zlib.git external/zlib
$ git clone git://android.git.kernel.org/platform/bionic.git bionic
$ echo "include build/core/main.mk" >Makefile
Now edit build/core/main.mk and comment out the parts labelled
# Check for the correct version of java
and
# Check for the correct version of javac
Since adb doesn’t need Java, these checks are unnecessary.
Also edit build/target/product/sdk.mk and comment out the “include” lines after
# include available languages for TTS in the system image
Now, since we are one a x64 machine we need to install the rest of the libraries to cross compile abd. I think this is the minimum you need to successfully build adb
sudo apt-get install libc6-dev-i386 lib32ncurses5-dev ia32-libs g++-multilib
The result should be something like this :
$make out/host/linux-x86/bin/adb

Now something very important that made me wonder for a while. By default android does not allow any connection with adb. To use it you must enable it on the phone. Then go Applications then Development. Under here you want to switch on Stay awake so that your screen stays visible while connected to your main system.
Finally, you can talk to your phone. Success !
