Android适配全面总结（三）----ROM适配

找到手机设置 ---> 最后的开发人员选项 ---> 在调试模块,打开USB调试。 
还是调试模块内,找到日志记录器缓冲区大小,改为1M(也可选择更大)，
然后进入拨号界面输入：*#*#2846579#*#*  ----> 选择USB端口设置 ----> 选择Google模式。

进入拨号界面输入：*#*#2846579#*#*
依次选择：后台设置 ---> LOG设置 ---> AP 日志，重新启动手机。

- 问题1. 测试的签名和你正式出包的签名如果不一致就不能安装，卸载应用也没用。
- 问题2. 用as安装过应用，卸载后安装正式的apk就安装不了，用adb命令卸载后就行了。
