This is the Android device configuration for Xperia (shinano platform).
To setup a tree and build images for the device do the following:
repo init as described by Google over at:
http://source.android.com/source/downloading.html
Put the following snippet in .repo/local_manifests/shinano.xml:
<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<remote name="sony" fetch="git://github.com/sonyxperiadev/" />
<remove-project name="platform/hardware/qcom/media" />
<remove-project name="platform/hardware/invensense" />
<remove-project name="platform/hardware/akm" />
<project path="device/sony/aries" name="device-sony-aries" groups="device" remote="sony" revision="master" />
<project path="device/sony/leo" name="device-sony-leo" groups="device" remote="sony" revision="master" />
<project path="device/sony/sirius" name="device-sony-sirius" groups="device" remote="sony" revision="master" />
<project path="device/sony/shinano" name="device-sony-shinano" groups="device" remote="sony" revision="master" />
</manifest>Download the zip file with vendor binaries from: http://developer.sonymobile.com/knowledge-base/open-source/android-open-source-project-for-xperia-devices/
In the root of your Android code tree unzip the corresponding vendor zip.
You should now have vendor directories named in your tree.
repo syncsource ./build/envsetup.shlunch aosp_xxxx-userdebugmake
To flash the images produced make sure your device is unlocked, as described on http://unlockbootloader.sonymobile.com/
Enter fastboot mode on the device by pressing volume up while inserting the USB
cable or execute adb reboot bootloader.
fastboot flash boot out/target/product/<device>/boot.imgfastboot flash system out/target/product/<device>/system.imgfastboot flash userdata out/target/product/<device>/userdata.img
Reflashing userdata is not necessary every time, but incompatibilities with previous content might result in a device that doesn't boot. If this happens try to reflash just the userdata again.
