copied!<p>I had a similar need in my project and ended up having to use both.</p> <p>The android.net.wifi.supplicant.CONNECTION_CHANGE action sends a broadcast when the network is connected, but usually before the device has an IP address, so I needed the android.net.wifi.STATE_CHANGE action for that.</p> <p>The android.net.wifi.STATE_CHANGE action receives a broadcast on disconnect only if the device is disconnecting from a network, but wifi is still enabled (when hotspot goes out of range, for example)</p> <p>So you should put both actions for the receiver in the manifest:</p> <pre><code><receiver android:name="net.moronigranja.tproxy.WifiReceiver"> <intent-filter> <action android:name="android.net.wifi.STATE_CHANGE"/> <action android:name="android.net.wifi.supplicant.CONNECTION_CHANGE" /> </intent-filter> </receiver> </code></pre> <p>and you put an if to check which action is being called in the intent. Here is the onReceive method of the BroadcastReceiver in my code:</p> <pre><code>public void onReceive(Context c, Intent intent) { if(intent.getAction().equals(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION)){ boolean connected = intent.getBooleanExtra(WifiManager.EXTRA_SUPPLICANT_CONNECTED, false); if(!connected) { //Start service for disconnected state here } } else if(intent.getAction().equals(WifiManager.NETWORK_STATE_CHANGED_ACTION)){ NetworkInfo netInfo = intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO); if( netInfo.isConnected() ) { //Start service for connected state here. } } } </code></pre>
