Android: Check network and real internet connectivity

Question

Below is the piece of Android code which works fine to check if network is connected or not.

public static boolean isNetworkAvailable(Context context) 
{
            


        

Answer 1

Issue #1:
Android device connected to a Wi-Fi, which turns out to be a private network.
So isNetworkAvailable will return that network is connected, but could not be connected to any other service.

Issue #2:
Sometimes the phone signal shows it is connected to service provider data plan. so network connectivity is true , but still cannot access google/yahoo.

I'm not sure about Issue #1 but I'm sure that following approach will solve Issue #2.

Ultimately, you will need to Monitor the change in Network connection,

Step 1:

Just register a BroadcastReceiver for following action

Step 2:

when you get callback on onReceive(Context context,Intent intent) method ,check for connectivity status.

i.e: boolean isConnected = getIntent().getExtras().getBoolean(ConnectivityManager.EXTRA_NO_CONNECTIVITY);

//apart from EXTRA_NO_CONNECTIVITY, there are other parameters also which will be useful to monitor
