inner MainActivity:
class Receiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(
android.net.ConnectivityManager.CONNECTIVITY_ACTION)) {
} else if(intent.getAction().equals(android.net.WifiManager.SCAN_RESULTS_AVAILABLE_ACTION)) { //here is the error
}
}
} <receiver android:name=".ConnectionBroadcast" >
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
</intent-filter>
<intent-filter>
<action android:name="android.net.wifi.SCAN_RESULTS" />
</intent-filter>
</receiver>回答1:
Just try this The best that worked for me:
AndroidManifest
<receiver android:name="com.AEDesign.communication.WifiReceiver" >
<intent-filter android:priority="100">
<action android:name="android.net.wifi.STATE_CHANGE" />
</intent-filter>
</receiver>
BroadcastReceiver class
public class WifiReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
NetworkInfo info = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
if(info != null) {
if(info.isConnected()) {
// Do your work.
// e.g. To check the Network Name or other info:
WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
String ssid = wifiInfo.getSSID();
}
}
}
}
