Downloading and building
========================
-Building for Android requires full Android AOSP source tree. Sample Android-IA
-tree with all required components present is available at

+Building for Android requires full Android AOSP source tree. Sample Android
+4.4.2 tree with all required components present is available at
+http://code.google.com/p/aosp-bluez/
+
+This tree provides support for Nexus4 (target aosp_mako-userdebug) and
+Nexus 7 2013 (target aosp_flo-userdebug). Tree does not provide binary blobs
+needed to run Android on supported devices. Those can be obtained from
+https://developers.google.com/android/nexus/drivers. Binary blobs needs to be
+unpacked (EULA acceptance required) into 'vendor' directory of Android tree.
Downloading:
-repo init -u https://code.google.com/p/android-bluez.manifest/ -m topics/bluez
+repo init -u https://code.google.com/p/aosp-bluez.platform-manifest -b kitkat
repo sync
-Build for Intel ultrabook:
-'source build/envsetup.sh'
-'lunch core_mesa-eng'
-'make allimages -j8'
+Building:
+source build/envsetup.sh
+lunch aosp_mako-userdebug or lunch aosp_flo-userdebug
+make -j8
+
+Flashing:
+adb reboot bootloader
+fastboot flashall -w
After full build is done it is possible to rebuild only BlueZ:
'cd external/bluetooth/bluez/android/'
'mm' (or 'mm -B' to force rebuilding of all files)
'adb sync' to update target device.
