androidをビルトしてみる

- ビルドに必要なパッケージをインストールする。Get Android Source Code | Android Open Sourceの Setting up your machine の Ubuntu Linux のところ参照
# apt-get install git-core gnupg sun-java5-jdk flex bison gperf \
                  libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential \
                  zip curl libncurses5-dev zlib1g-dev 
注意、'libsdl-dev' の代わりに 'libsdl1.2-dev' を選択しています
E: パッケージ sun-java5-jdk が見つかりません

// sun-java-5-jdk は sun-java6-jdk になったがこれをインストールするにはレポジトリ追加をしないといけない 
// これからは openjdk-6-jdk らしい
# aptitude install openjdk-6-jdk


$ curl http://android.git.kernel.org/repo >~/bin/repo
$ chmod a+x ~/bin/repo
$ repo init -u git://android.git.kernel.org/platform/manifest.git
$ repo sync
... DL5GBくらい。timeコマンド付けて実行すればよかった・・・

仕方ないので Eclair (2.1) のブランチに切り替える
$ repo init -u git://android.git.kernel.org/platform/manifest.git -b eclair

あちゃー openjdk-6-jdk じゃだめだったかsun-java6-jdkやってみる。
レポジトリ追加してインストールできるようにする

$ sudo add-apt-repository "deb http://archive.canonical.com/ maverick partner"
$ sudo apt-get update
$ sudo apt-get install sun-java6-jdk
ライセンスに同意する。

java環境を切り替える
$ sudo update-alternatives --config java
$ sudo update-alternatives --config javac
There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                      優        Status
------------------------------------------------------------
* 0            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      auto mode
  1            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      manual mode
  2            /usr/lib/jvm/java-6-sun/jre/bin/java       63        manual mode

Press enter to keep the current choice[*], or type selection number: 2
update-alternatives: using /usr/lib/jvm/java-6-sun/jre/bin/java to provide /usr/bin/java (java) in manual mode.

うええ。やはりsun-java-5-jdkじゃないとダメ？
→　sun-java-5-jdk見つからない。

結局元に戻す。

$ ./emulator -wipe-dataemulator: ERROR: You did not provide the name of an Android Virtual Device
with the '-avd <name>' option. Read -help-avd for more information.

If you *really* want to *NOT* run an AVD, consider using '-data <file>'
to specify a data partition image file (I hope you know what you're doing).

Android仮想デバイス(AVD)というものが必要らしい。

・・なんか起動したけど・・・？

上記エミュレータを起動して仮想デバイスを作成。
作った仮想デバイスは ~/.android/に保存されるのでこれにビルドしたものを差し替えたりすればいいのかしらん。
