How To Check The Internet Connectivity Within The Network In Android (using Internet Of Some Other Device Through Hotspot)

I have a requirement where I want to check whether there is any internet connectivity when I am connected with the network. For example, I have device A and device B. Device A is c

Solution 1:

It can be a ridiculous solution but i think also it could be real solution:

publicbooleanisOnline() {
    ConnectivityManagercm= (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfonetInfo= cm.getActiveNetworkInfo();
    if (netInfo != null && netInfo.isConnected()) {
        try {
            URLurl=newURL("http://www.google.com");
            HttpURLConnectionurlc= (HttpURLConnection) url.openConnection();
            urlc.setConnectTimeout(3000);
            urlc.connect();
            if (urlc.getResponseCode() == HttpURLConnection.HTTP_OK) {
                returnnewBoolean(true);
            }
        } catch (MalformedURLException mue) {
            // TODO Auto-generated catch block
            mue.printStackTrace();
        } catch (IOException ie) {
            // TODO Auto-generated catch block
            ie.printStackTrace();
        }
    }
    returnfalse;
}

Solution 2:

Try the below function to check your internet connection:

publicstaticbooleanisInternetConnected(Context mContext) {

        try {
            ConnectivityManagerconnect=null;
            connect = (ConnectivityManager) mContext
                    .getSystemService(Context.CONNECTIVITY_SERVICE);

            if (connect != null) {
                NetworkInforesultMobile= connect
                        .getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

                NetworkInforesultWifi= connect
                        .getNetworkInfo(ConnectivityManager.TYPE_WIFI);

                if ((resultMobile != null && resultMobile
                        .isConnectedOrConnecting())
                        || (resultWifi != null && resultWifi
                                .isConnectedOrConnecting())) {
                    returntrue;
                } else {
                    returnfalse;
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        returnfalse;
    }

Add the following permissions to your manifest file,

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