myFirstApp android app

之前作为业余时间的兴趣，玩过android app。近期学习ros发现rosjava早晚要用到。因此，把android app和java的经验也要攒起来。

重新玩下这个。

adb devices 阶段

ddms配置阶段

在仅有apk情况下，可以使用如下命令行方式adb

1. 安装程序 adb install ebook.apk

2. 重安装程序 adb install -r ebook.apk

3. 卸载程序 adb uninstall net.blogjava.mobile.ebook

只卸载应用程序，保留缓冲和数据 adb uninstall -k net.blogjava.mobile.ebook

4. 指定具体机器

如果机器上有多个模拟器或真机实例，需要使用-s命令行参数指定具体的模拟器或真机。

5.直接运行程序。

A. 在emulator-5554模拟器上运行ebook.apk

adb -s emulator-5554 shell am start -n net.blogjava.mobile.ebook/net.blogjava.mobile.ebook.Main

B. 在真机上运行ebook.apk

adb -s HT9BYL904399 shell am start -n net.blogjava.mobile.ebook/net.blogjava.mobile.ebook.Main

其中Main是ebook.apk的主Activity。（记得输入包名前面是路径，后面还要再输入全称）相当于Windows应用程序的主窗体或Web应用程序的主页面。am是shell命令。

To get started, you’ll need to install OpenJDK or Oracle Java JDK. The OpenJDK version comes with Ubuntu and it’s very easy to install.
