Android热点、WiFi、蓝牙等功能开启和关闭

Android热点、WiFi、蓝牙等功能开启和关闭

1、需要添加权限，选择自己需要的添加，热点的开启和关闭可能还需要权限；

<!--设备(亮屏)权限-->
<user-permission android:name="android.permission.DEVICE_POWER" />
<!--息屏权限-->
<uses-permission android:name="android.permission.WAKE_LOCK" />
<!--蓝牙权限-->
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<!-- wifi和热点权限 -->
<uses-permission
    android:name="android.permission.WRITE_SETTINGS"
    tools:ignore="ProtectedPermissions" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE"/>
<!-- 网络权限 -->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CHANGE_NETWORKE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/>

2、下面是操作代码工具类：

import android.annotation.SuppressLint;
import android.app.admin.DevicePolicyManager;
import android.bluetooth.BluetoothAdapter;
import android.content.Context;
import android.net.wifi.WifiConfiguration;
import android.net.wifi.WifiManager;
import android.os.PowerManager;
import android.util.Log;
import com.example.txzvoicedemo.SDKDemoApp;
import java.lang.reflect.Method;
