这里面也写了获取本机手机号码的代码，但是测试之后发现只有华为nove3 才可以获取到，不过其他一些重要的信息都可以拿到，MAC，IMEI，IMSI，ICCID。

想测试的话，这个是Apk包地址   百度云链接：https://pan.baidu.com/s/1_L2oc0PDORzdy72j5o-K1w  密码：ldq8 

上代码吧

这是一些权限

    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
    <uses-permission android:name="android.permission.SYSTEM_OVERLAY_WINDOW" />

这里Main2Activity是程序入口

                Log.d(TAG, "未授权,去授权");
