[Android] Android.mkでapkファイルを作ってみる

Androidのソースツリー内のツールを使って、SDKで配布するapkパッケージを作ってみる。
まずは、サンプルのHelloActivityを参考に、Android.mkを作成する。

$ pwd
/home/kinami/mydroid/development/samples
$ mkdir HelloAndroid
$ cd HelloAndroid/
$ activitycreator jp.hews.hello.HelloAndroid
Package: jp.hews.hello
Output directory: /home/kinami/mydroid/development/samples/HelloAndroid
Activity name: HelloAndroid
...
$ cp ../HelloActivity/Android.mk .
$ vi Android.mk
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := samples

# Only compile source java files in this apk.
LOCAL_SRC_FILES := $(call all-java-files-under, src)

LOCAL_PACKAGE_NAME := HelloAndroid  <== ここを変更

LOCAL_SDK_VERSION := current

include $(BUILD_PACKAGE)

# Use the following include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))

この状態で、makeしてみる

$ mm
make: ディレクトリ `/home/kinami/mydroid' に入ります

make: *** [out/target/common/obj/APPS/HelloAndroid_intermediates/src/R.stamp] エラー 1
make: ディレクトリ `/home/kinami/mydroid' から出ます

ということで、Viewに直接テキストを書いているとローカライズできないのでだめよというチェックが入っている。正しいチェック！
strings.xmlとmain.xmlを変更

strings.xmlに以下を追加
    Hello, Android
main.xmlで以下を変更
    android:text="@string/hello"

これで、再度make。showcommandsで何をやっているのかをチェック

$ mm showcommands
make: ディレクトリ `/home/kinami/mydroid' に入ります

これで、とりあえず、パッケージは作成さえた。
