一、参考
1、Android 获取手机的厂商、型号、Android系统版本号、IMEI、当前系统语言等工具类
2、Android获取SD卡总容量，可用大小，机身内存总容量及可用大小的系统方法
3、android 安卓APP获取手机设备信息和手机号码的代码示例
4、Android 获取本机号码

三、权限
部分功能需要权限获得，补充下，android 6.0之后需要动态获取权限，具体查看权限管理的相关资料
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_PHONE_NUMBERS" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
