android-1.5r3 for bc9 (bc9-android-sdk-release20090815 ver,) †
Checkout android-1.5r3 and modify it.
- android-1.5r3 is a tag branch, which is created right after android-sdk-1.5_r3
- android-1.5r3 is a tag brach, which is put fort cupcake-relase branch.
- The kernel source of android-1.5r3 is excluded from repo management. If the kernel is required, it can be obtain from git, separately.
Get Source †
android-1.5r3 branch †
Following the instructions below, obtain source code of android.
$ mkdir ~/android-1.5r3
$ cd android-1.5r3
$ repo init -u git://android.git.kernel.org/platform/manifest.git -b android-1.5r3
$ repo sync
ALSA †
android-1.5r3 branch is a tag branch of the cupcake-release branch, and this tag branch is created at a specific time during the
cupcake-release branch. Since this is not the master brach of cupcake branch, ALSA can not be included as writing the additional
information of ALSA in local_manifest.xml and ordering repo sync command. Including ALSA, get the ALSA files via git, and place
these files at the source tree of android-1.5r3. Then, build the android 1.5r3. Also, the error will be occur if it uses alsa_sound, which
is committed later then August 2009. alsa_sound used here is the last committed on July 2009. The instructions of how to include
ALSA is shown below.
$ cd ~android-1.5r3/external
$ git clone git://android.git.kernel.org/platform/external/alsa-lib.git
$ cd alsa-lib
$ git checkout 7d7fc0e
$ cd ~android-1.5r3/hardware
$ git clone git://android.git.kernel.org/hardware/alsa_sound
$ cd alsa_sound
$ git checkout a5cf8cc
Adjust the Contents of build †
Adjust alsa-lib †
Modify android-1.5r3/external/alsa-lib/Android.mk. The details are defined below.

Patch for power management †
Please apply the patch listed below before build the files. Without applying this patch, bc9 will not boot as the system is considered
as low level battery.

As changing android-1.5r3/hardware/libhardware_legacy/wifi/wifi.c, make USB Wi-Fi, which is compatible with rt73usb driver,
accessible from Android's GUI. To check progress of the process, the code below includes the log-outs. If all log-outs are not
necessary, please adjust the amount of log-outs by comment out.

sound source file †
AudioPackage2.mk is copied, and change its name to Android.mk. This will help that ringtone and other resource files are needed
to be copied to the right places when build the files.

build †
As these fixings and adjustments shown above are completed, execute build.
$ cd ~/android-1.5r3
$ make
Technically, build is completed, but the lib files of OpenWnn, which is located under the directory of
android-1.5r3/out/target/product/generic/system/lib, have not been built. OpenWin is needed to be
build separately.
Additional Build †
OpenWnn †
As bc9 is basically works inside landscape, turn off the comment out function of at the landscape configuration for OpenWnn, and let landscape visible.
android-1.5_r3/packages/inputsmethod/OpenWnn/src/jp/co/omronsoft/openwnn/JAJP/DefaultSoftKeyboardJAJP.java can be change to the code shown
below.

After the change is completed. OpenWnn can be built, separately.
$ cd ~/android-1.5_r3/build/
$ source envsetup.sh
$ cd ~/android-1.5_r3/packages/inputmethods/OpenWnn
$ mm
Finally, the lib files for OpenWnn are built under ~/amdroid-1.5r3/out/target/product/generic/syste/lib.
Create android-root †
Place the built android file †
The whole build process described above is completed, the built files are moved to specific locations where each file is suitable for booting.
$ cd ~/
$ mkdir android-root
$ cp -a ~/android-1.5r2/out/target/product/generic/root/* ~/android-root/
$ cp -a ~/android-1.5r2/out/target/product/generic/system/* ~/android-root/system/
Place kernel module †
The rt73usb related kernel module and the firmware of rt73 are placed under android-root. After Android is booted via chroot, let
users turn on/off Wi-Fi from GUI of android via applying insmod/rmmod commands on the driver, respectively. The instructions
are shown below.
Caution: As using kernel module, bc9 is needed to be booted from the same version of kernel and kernel module.
$ mkdir ~/android-root/system/lib/modules/
$ cp ~/kernel_work/linux-android-2.6.29-bc9-r6/drivers/net/wireless/rt2x00/*.ko ~/android-root-1.5r3-alsa-wifi/system/lib/modules/

Edit init.rc †
The confutations of android-root/init.rc is needed to change for adding alsa and Wi-Fi. The modified code is shown below.

Configure alsa file †
Copy the ALSA configuration files at /android-root/system/etc/. The configuration files are listed below.
 asound.conf & asound.state
asound.state †
asound.state is generated at OpenEmbedded's directory of /etc/ when OpenEmbedded environment is built from gumstix-oe.
asound.conf †
asound.conf is created for letting each control work correctly on asound.state.
vold configuration file †
For Android, SDcard is mounted as /system/bin/vold/ is executed.
vold works as its configuration file, which is located at android/system/etc/vold.conf is predetermined. The configuration file of vold'''
is defined as shown below.
## vold configuration file for bc9
volume_sdcard {
media_path /devices/platform/pxa2xx-mci.0/mmc_host/mmc0
media_type mmc
mount_point /sdcard
ums_path /devices/platform/usb_mass_storage/lun0
}
Because of this configuration, the first partition of microSD is mounted as saving media file.
Put the files pictures, audio, and videos on the first partition, these files are accessible from Android.
Configuration of button setting †
From the top, bc9's buttons are set for, HOME, MENU, and BACK.
bc9 has three buttons, which is connected via GPIO. The buttons are assigned as F1, F2, and F3 of keyboard, and these keys are
used for HOME, MENU, and BACK. To use the buttons, modify qwerty.kl located at android-root/system/usr/keylayout/qwerty.kl.

At the end of default.prop, set up the IP of OpenDNS as it is shown below.
(If the use of OpenDNS is prohibited, set up any available DNS server address in bc9's working environment)
net.eth0.dns1=208.66.222.222
net.dns1=208.67.222.222
Screen Timeout †
Since Power Management function is cancelled by application of the patch, once android turns into sleep mode via Screen Timeout, android
will not turn on again. Screen Timeout is needed to be turned off. As android is booted , please reconfigure the following section.
- [Menu] - [Settings] – [Sound & display] – [Screen timeout] – [Never timeout]
device_provisioned †
activation related setting affects on the Open Source version of android, too. After android is initially booted, a db file is generated.
Giving the command, shown below, on the file, android becomes activated. (This command is not executed in the userland of android.
This should be on Linux and applying sqlite3.)
# cd /data/data/com.android.providers.settings/databases
# sqlite3 settings.db
sqlite> insert into "secure" values(NULL,"device_provisioned", "1");
sqlite> .exit
Once android is activated, the key lock dialog will be added on HOME screen after android is booted.
Before android is activated, HOME
screen immediately appears after android is booted. After android is activated, the key lock dialog appears after booting android. Then,
pushing MENU button, reach HOME screen. On the key lock dialog, the message of No SIM Card appears, but it means that bc9 is not
capable of connecting to 3G communication. Ethernet can be usedfor communication.
As users fails to activate android, these issues are recognized.
- HOME key is cancelled.
- While android is booting, key dialog does not appears.
This ends the build and preparation process of android 1.5-r3 on bc9.
