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.content.Context;
import android.net.ConnectivityManager;
import android.net.wifi.WifiConfiguration;
import android.net.wifi.WifiManager;
import android.os.Build;
import android.os.Handler;

import android.util.Log;
import com.android.dx.stock.ProxyBuilder;
import java.io.File;
import java.lang.reflect.InvocationHandler;
import java.lang.reflect.Method;
@RequiresApi(api = Build.VERSION_CODES.O)
public class TestOreoWifiManager {

mContext = c;
mWifiManager = (WifiManager) mContext.getSystemService(Context.WIFI_SERVICE);
mConnectivityManager = (ConnectivityManager) mContext.getSystemService(ConnectivityManager.class);
}
/**

* Call this before {@code startTethering} if app is a system/privileged app

*/
public void configureHotspot(String name, String password) {
WifiConfiguration apConfig = new WifiConfiguration();
apConfig.SSID = name;
apConfig.preSharedKey = password;
apConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);

Log.d(TAG, "setWifiApConfiguration - success? " + status);
} catch (Exception e) {
Log.e(TAG, "Error in configureHotspot");
e.printStackTrace();
}
}
/**
* Checks where tethering is on.
* This is determined by the getTetheredIfaces() method,
* that will return an empty array if not devices are tethered
*
* @return true if a tethered device is found, false if not found
*/
/*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);
Log.d(TAG, "getTetheredIfaces invoked");
Log.d(TAG, Arrays.toString(res));
if (res.length > 0) {
return true;
}
}
} catch (Exception e) {

e.printStackTrace();
}
return false;
}
*/

*/
public boolean startTethering(final TestOnStartTetheringCallback callback) {
// On Pie if we try to start tethering while it is already on, it will
// be disabled. This is needed when startTethering() is called programmatically.
/*if (isTetherActive()) {
Log.d(TAG, "Tether already active, returning");
return false;
}*/
File outputDir = mContext.getCodeCacheDir();
Object proxy;
try {
proxy = ProxyBuilder.forClass(OnStartTetheringCallbackClass())
.dexCache(outputDir).handler(new InvocationHandler() {
@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
switch (method.getName()) {

break;

break;
default:

}
return null;
}
}).build();
} catch (Exception e) {

e.printStackTrace();
return false;
}
Method method = null;
try {

if (method == null) {
Log.e(TAG, "startTetheringMethod is null");
} else {

Log.d(TAG, "startTethering invoked");
}
return true;
} catch (Exception e) {

}
return false;
}
public void stopTethering() {
try {

} catch (ClassNotFoundException e) {
Log.e(TAG, "OnStartTetheringCallbackClass error: " + e.toString());

}
return null;
}
}
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();
}
}
