Useful Android app developers term of the day: NetworkReceiver

Android NetworkReceiver is a system-level component that allows apps to receive notifications when the device's network connectivity status changes. This includes changes in the type of network connection (such as switching from Wi-Fi to cellular), changes in network availability (such as connecting or disconnecting from a network), and changes in network quality (such as changes in signal strength).

The NetworkReceiver works by registering a broadcast receiver in the app's manifest file. When a network event occurs, the Android system sends an Intent broadcast, which triggers the registered receiver. The receiver can then handle the event and take appropriate action, such as updating the user interface or starting a network operation.

To use the NetworkReceiver in an app, you need to add the following permission to the manifest file:

php
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

You also need to register the receiver in the manifest file, like this:

php
<receiver android:name=".MyNetworkReceiver"> <intent-filter> <action android:name="android.net.conn.CONNECTIVITY_CHANGE" /> </intent-filter> </receiver>

In this example, the receiver class is named "MyNetworkReceiver", and it is registered to receive the "CONNECTIVITY_CHANGE" action.

Once the receiver is registered, you can override the onReceive() method to handle network events, like this:

public class MyNetworkReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { // Handle network event here } }

In the onReceive() method, you can use the ConnectivityManager class to obtain information about the current network connection, like this:

ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = connMgr.getActiveNetworkInfo(); if (networkInfo != null && networkInfo.isConnected()) { // Connected to a network } else { // No network connection }

With the NetworkReceiver, you can build apps that respond to changes in network connectivity, and provide a better user experience by adapting to changing network conditions.


In Android, a NetworkReceiver is a broadcast receiver that listens for network connectivity changes. It allows your app to be notified when the device's network connectivity state changes, such as when the device connects to a Wi-Fi network or when the device loses its mobile data connection.

To use a NetworkReceiver in your app, you need to first declare it in your AndroidManifest.xml file. Here's an example:

xml
<receiver android:name=".MyNetworkReceiver"> <intent-filter> <action android:name="android.net.conn.CONNECTIVITY_CHANGE" /> </intent-filter> </receiver>

In the example above, we're declaring a NetworkReceiver called MyNetworkReceiver and specifying that it should listen for the android.net.conn.CONNECTIVITY_CHANGE intent.

Once you've declared your NetworkReceiver, you can implement the onReceive() method to handle the network connectivity changes. Here's an example implementation:

public class MyNetworkReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo activeNetwork = cm.getActiveNetworkInfo(); boolean isConnected = activeNetwork != null && activeNetwork.isConnectedOrConnecting(); if (isConnected) { // Do something when the device is connected to a network } else { // Do something when the device is not connected to a network } } }

In the onReceive() method above, we're using the ConnectivityManager to check the network connectivity state and performing some action based on whether the device is connected to a network or not.

Remember to add the necessary permissions to your AndroidManifest.xml file to access the network information.

xml
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
