This article mainly explains "the method of monitoring network state in Android". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "the method of monitoring network state in Android".

When the state of the network changes, the system will send out an android.net.conn.CONNECTIVITY_CHANGE broadcast

When the phone is unlocked, the system will issue an android.intent.action.USER_PRESENT broadcast. Here, in order to get it when the phone is unlocked, I add the cell phone unlock event broadcast.

After registering for Receiver, you can receive broadcasts of network status changes and mobile phone unlocking actions in ConnctionChangeReceiver.

Secondly, we deal with the received broadcasts by adding network state judgment to onReceive.

ConnectivityManager connectMgr = (ConnectivityManager) context.getSystemService (Context.CONNECTIVITY_SERVICE); NetworkInfo mobNetInfo = connectMgr.getNetworkInfo (ConnectivityManager.TYPE_MOBILE); NetworkInfo wifiNetInfo = connectMgr.getNetworkInfo (ConnectivityManager.TYPE_WIFI)

ConnectivityManager gets the current system service information

GetNetworkInfo acquires the information of two networking methods, MOBILE and WIFI, respectively.

The current networking status is determined by judging the Boolean Boolean values returned by mobNetInfo.isConnected () and wifiNetInfo.isConnected ().

If (! mobNetInfo.isConnected () & &! wifiNetInfo.isConnected ()) {/ / unconnect network} else {/ / connect network}

Only whether it is currently connected to the network is added here. If you need to distinguish between data connection and WIFI connection, you can judge separately.

Note here that Android permission access is added
