How to check that app have internet connection or not in android

This post is to "Detecting internet connection status in your app"  its  very easy to do , below is the code how to do this:-

1. Open your manifests file and take following permission  :-

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

2. Open your class where you wants to check the internet connection and write one method like following this method will return true or false :-

private boolean amIConnected() {
    ConnectivityManager connectivityManager = (ConnectivityManager) 

getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
    return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}

3. Now call this method in onCreate of class like following :-

if(amIConnected()) {
    Log.d("supriya","..user is connected"+amIConnected());
} else {
    Log.d("supriya","not connected");
}

4. Full code like following :-

public class MainActivity extends AppCompatActivity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        if(amIConnected()) {
            Log.d("supriya","..user is connected"+amIConnected());
        } else {
            Log.d("supriya","not connected");
        }
    }

    private boolean amIConnected() {
        ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService

(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
        return activeNetworkInfo != null && activeNetworkInfo.isConnected();
    }
}
