Confirm Internet Data Connection Before Making Firestore Query

I have the following situation: The application has the option to like the posts of a user. And also has a Dislike option. It is working properly when it is on a wifi or mobile net

Solution 1:

A simple approch will be use the following method:

publicbooleanisInternetAvailable() {
    Runtimeruntime= Runtime.getRuntime();
    try {
        Processprocess= runtime.exec("/system/bin/ping -c 1 8.8.8.8");
        intexitValue= process.waitFor();
        return (exitValue == 0);
    } catch (IOException | InterruptedException e) {
        e.printStackTrace();
    }
    returnfalse;
}

Solution 2:

There are two ways to do this thing one is check at a instance and another is making a broadcast receiver

publicstaticbooleaninternetAvailable(Context context) {
    ConnectivityManagerconnectivityManager= (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfoactiveNetworkInfo=null;
    if (connectivityManager != null) {
        activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
    }
    return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}

And the other one is

publicclassNetworkChangeReceiverextendsBroadcastReceiver {
publicstaticfinalStringTAG="NetworkChangeReceiver";
publicstatic ConnectivityReceiverListener connectivityReceiverListener;

publicNetworkChangeReceiver() {
    super();
}

@OverridepublicvoidonReceive(Context context, Intent intent) {
    ConnectivityManagercm= (ConnectivityManager) context
            .getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfoactiveNetwork=null;
    if (cm != null) {
        activeNetwork = cm.getActiveNetworkInfo();
    }
    booleanisConnected= activeNetwork != null
            && activeNetwork.isConnectedOrConnecting();

    if (connectivityReceiverListener != null) {
        connectivityReceiverListener.onNetworkConnectionChanged(isConnected);
    }
}

publicinterfaceConnectivityReceiverListener {
    voidonNetworkConnectionChanged(boolean isConnected);
}

}

Happy Coding :)
