You have to instantiate an object of type Apppreference in order to access its methods (unless they are static)

checkInternet() is non-static you need an instance of AppPreferences in your activity and use the method on this instance:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.lo_loading);
    AppPreferences appPrefs = new AppPreferences()
    appPrefs.checkInternet()
}

Another solution is to make checkInternet() static.
