Question

I am stuck with following problem.I want my application to exit if it detects no network connection.My application starts with splash screen.Is it possible to show splash screen followed by toast if no network connection is on device.and then terminate the application

I have something like this in my splash screen code :

Inside onCreate()

ConnectivityManager connectivitymanager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkinfo = connectivitymanager.getActiveNetworkInfo();
        connected = networkinfo != null && networkinfo.isAvailable()
                && networkinfo.isConnected();
        Log.v("Network state : ", connected + "");

        Thread splashThread = new Thread() {
            @Override
            public void run() {
                try {
                    int waited = 0;
                    while (waited < 5000) {
                        sleep(100);
                        waited += 100;
                    }
                } catch (InterruptedException e) {
                    // do nothing
                } finally {
                    Looper.prepare();
                    if (connected == false) {
                        Toast.makeText(
                                splashscreenActivity.this,
                                "No Network Connection is available on device.",
                                Toast.LENGTH_LONG).show();
                        finish();
                        System.exit(0);
                    } else {
                        finish();
                        startActivity(new Intent(splashscreenActivity.this,
                                mainActivity.class));
                    }
                    Looper.loop();
                }
            }
        };
        splashThread.start();

1.Please see my code and guide me how can i show up that toast.
2.Or suggest me some other better way to do this

Thanks

EDIT :

Thank you everybody for replying :

I opted Dharmendra’s way of showing toast via splashscreen activity :

The code that worked for is :

if (connected == false) {
            splashscreenActivity.this.runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    Toast.makeText(splashscreenActivity.this,
                            "No Internet Connection.", 3000).show();
                }
            });
            finish();
        } else {
            //migrate to main activity from splashscreen
        }

You are creating and showing Toast from Thread so it may be not called

You have to write this code

splashscreenActivity.this.runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    Toast.makeText(c, "Internet connection not currently available.", 3000).show();
                }
            });
