Android 6.0 打开WIFI 热点问题

6.0手机，开启WiFi热点报错InvocationTargetException。把targetSdkVersion 改成22 可以打开  23不行    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
权限都加了，而且位置权限也给了，GPS也打开了，23还是不行。打开WIFI代码    targetSdkVersion 22 是可以运行的，我就想知道targetSdkVersion 23要怎么样才能运行呢
