本篇文章给大家分享的是有关Android中怎么实现一个手机管理工具类，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。
工具类内的方法：
getInstance : 单例对象
getSDKVersionNumber : 获取手机系统版本号
getPhoneModel : 获取手机型号
getPhoneWidth : 获取手机宽度
getPhoneHeight : 获取手机高度
getPhoneImei : 获取手机imei串号 ,GSM手机的 IMEI 和 CDMA手机的 MEID
getPhoneSim : 获取手机sim卡号
getPhoneNum : 获取手机号
isSDCardMount : 判断sd卡是否挂载
getSDFreeSize : 获取sd卡剩余空间的大小
getSDAllSize : 获取sd卡空间的总大小
isTablet : 判断是否是平板
isApkInstalled : 判断一个apk是否安装
getAppPermissions : 获取应用权限 名称列表
getInstalledApp : 获取手机内安装的应用
getUserInstalledApp : 获取手机安装非系统应用
getInstalledAppInfo : 获取安装应用的信息
startAppPkg : 打开指定包名的应用
unInstallApk : 卸载指定包名的应用
callPhone : 直接呼叫指定的号码
toCallPhoneActivity : 跳转至拨号界面
sendMessage : 直接调用短信API发送信息(设置监听发送和接收状态)
toSendMessageActivity: 跳转至发送短信界面(自动设置接收方的号码)
