When developing an Android application that requires internet connectivity, it is important to check whether the device is connected to the internet or not. In this tutorial, we will show you how to check the Internet connection in Android using Java.
The following code snippet checks whether the device is connected to the internet or not:
public boolean isInternetConnected() {
ConnectivityManager connectivityManager = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}
This code snippet checks whether the device is connected to the internet or not by checking the active network information. If the active network information is not null and is connected, it returns true indicating that the device is connected to the internet.
To implement this code in your Android application, simply copy and paste the code snippet into your Java class. You may call the isInternetConnected()
method wherever you need to check for the internet connection.
In conclusion, checking for internet connectivity is an important aspect of developing Android applications that require internet connectivity. We hope that this tutorial has been helpful to you in understanding how to check the internet connection in Android using Java.
