Android 11 WiFi热点打开与关闭接口

Posted 2022-03-01 伟雪无痕

一.android11之前wifi Hotspot开启关闭方式

1.manfiest中添加权限

<!-- WiFi AP startTethering -->
<uses-permission android:name="android.permission.TETHER_PRIVILEGED" />

2. android8.0 Ap开启关闭方法

 public static void setWiFiApEnable(Context mContext, boolean value) 
        ConnectivityManager mConnectivityManager= (ConnectivityManager) mContext.getSystemService(Context.CONNECTIVITY_SERVICE);
        if (value) 
            mConnectivityManager.startTethering(ConnectivityManager.TETHERING_WIFI, false, new ConnectivityManager.OnStartTetheringCallback() 
                @Override
                public void onTetheringStarted() 
                    Log.d(TAG, "onTetheringStarted");
                    // Don't fire a callback here, instead wait for the next update from wifi.
                

                @Override
                public void onTetheringFailed() 
                  Log.d(TAG, "onTetheringFailed");
                  // TODO: Show error.
                
            );
         else 
            mConnectivityManager.stopTethering(ConnectivityManager.TETHERING_WIFI);
        
    

3.WiFiApReceiver广播接收

private static int isWiFiApState = WifiManager.WIFI_AP_STATE_FAILED;

    public static boolean isWiFiApOpened_O() 
        return (isWiFiApState == WifiManager.WIFI_AP_STATE_ENABLING || isWiFiApState == WifiManager.WIFI_AP_STATE_ENABLED);
    

    private final class WiFiApReceiver extends BroadcastReceiver 
        private boolean mRegistered;

        public void setListening(boolean listening) 
            if (listening && !mRegistered) 
                Log.d(TAG, "Registering receiver");
                final IntentFilter filter = new IntentFilter();
                filter.addAction(WifiManager.WIFI_AP_STATE_CHANGED_ACTION);
                mContext.registerReceiver(this, filter);
                mRegistered = true;
             else if (!listening && mRegistered) 
                Log.d(TAG, "Unregistering receiver");
                mContext.unregisterReceiver(this);
                mRegistered = false;
            
        

        public void onReceive(Context context, Intent intent) 
            isWiFiApState = intent.getIntExtra(
                    WifiManager.EXTRA_WIFI_AP_STATE, WifiManager.WIFI_AP_STATE_FAILED);
            String result = null;

            switch (isWiFiApState) 
                case WifiManager.WIFI_AP_STATE_DISABLED:
                    result = "DISABLED";
                    break;
                case WifiManager.WIFI_AP_STATE_DISABLING:
                    result =  "DISABLING";
                    break;
                case WifiManager.WIFI_AP_STATE_ENABLED:
                    result =  "ENABLED";
                    break;
                case WifiManager.WIFI_AP_STATE_ENABLING:
                    result =  "ENABLING";
                    break;
                case WifiManager.WIFI_AP_STATE_FAILED:
                    result =  "FAILED";
                    break;
            

            Log.d(TAG, "WiFi state : " + result);
        
    

二.android11的wifi Hotspot开启关闭方式，以proxy实现

1.定义回调接口

public abstract class TestOnStartTetheringCallback 
        /**
         * Called when tethering has been successfully started.
         */
        public abstract void onTetheringStarted();

        /**
         * Called when starting tethering failed.
         */
        public abstract void onTetheringFailed();

2.proxy类

import android.net.ConnectivityManager;
import android.net.wifi.WifiConfiguration;
import android.net.wifi.WifiManager;

import android.os.Handler;

    private static final String TAG = TestOreoWifiManager.class.getSimpleName();

    private Context mContext;
    private WifiManager mWifiManager;
    private ConnectivityManager mConnectivityManager;

    public TestOreoWifiManager(Context c) 
        mContext = c;
        mWifiManager = (WifiManager) mContext.getSystemService(Context.WIFI_SERVICE);
        mConnectivityManager = (ConnectivityManager) mContext.getSystemService(ConnectivityManager.class);
    

    /**
     * This sets the Wifi SSID and password

     */
    public void configureHotspot(String name, String password) 
        WifiConfiguration apConfig = new WifiConfiguration();
        apConfig.SSID = name;
        apConfig.preSharedKey = password;
        apConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
        try 
            Method setConfigMethod = mWifiManager.getClass().getMethod("setWifiApConfiguration", WifiConfiguration.class);
            boolean status = (boolean) setConfigMethod.invoke(mWifiManager, apConfig);
            Log.d(TAG, "setWifiApConfiguration - success? " + status);
         catch (Exception e) 
            Log.e(TAG, "Error in configureHotspot");
            e.printStackTrace();

    /*public boolean isTetherActive() 
        try 
            Method method = mConnectivityManager.getClass().getDeclaredMethod("getTetheredIfaces");
            if (method == null) 
                Log.e(TAG, "getTetheredIfaces is null");
             else 
                String res[] = (String[]) method.invoke(mConnectivityManager, null);

        // be disabled. This is needed when startTethering() is called programmatically.

                                    ProxyBuilder.callSuper(proxy, method, args);
                            
                            return null;
                        

                    ).build();

3.调用方法

@RequiresApi(api = Build.VERSION_CODES.O)
    public static void setHotspotOnPhone(Context mContext, boolean isEnable) 

        if (mTestOreoWifiManager ==null)
            mTestOreoWifiManager = new TestOreoWifiManager(mContext);
        


        if (isEnable)
            TestOnStartTetheringCallback callback = new TestOnStartTetheringCallback() 
                @Override
                public void onTetheringStarted() 
                

                @Override
                public void onTetheringFailed() 

                
            ;

            mTestOreoWifiManager.startTethering(callback);
        else
            mTestOreoWifiManager.stopTethering();
