Android Permission 权限 工具类

【导读】
为了方便Android 6.0的权限申请，记录两个工具类的使用。一是通过单独的activity去申请，一是通过BaseActivity去申请。

【步骤】

    <!--AndroidManifest.xml 申请需要的权限-->
    <uses-permission android:name="android.permission.CAMERA"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission android:name="android.permission.RECORD_AUDIO"/>
    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
    <uses-permission android:name="android.permission.CALL_PHONE"/>
    <uses-permission android:name="android.permission.READ_CALL_LOG"/>
    <uses-permission android:name="android.permission.WRITE_CALL_LOG"/>
    <uses-permission android:name="android.permission.USE_SIP"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.BODY_SENSORS"/>
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
