Please find my code a below..
---------------------------------------------------------------
Activity Code
public class Launcher extends Activity {
private IMainService mService = null;
TextView tView1 = null;
String testvar1 = "";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.status_display);
tView1 = (TextView)findViewById(R.id.feed_service_status);
bindService(new Intent(IMainService.class.getName()), serCon,
Context.BIND_AUTO_CREATE);
Button refresh_button =
(Button)findViewById(R.id.refresh_button);
refresh_button.setOnClickListener(new
View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
fill_vals(); ////--->Can access from here
}
});
fill_vals(); ////---- Cannot Access from here...
mService goes null and throw nullpointerexception.
}
private void fill_vals() {
String tets = "";
try {
tets = mService.ServiceStatus();
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
tets = e.getMessage();
}
}
public ServiceConnection serCon = new ServiceConnection() {
@Override
public void onServiceDisconnected(ComponentName name) {
// TODO Auto-generated method stub
}
@Override
public void onServiceConnected(ComponentName name, IBinder
service) {
// TODO Auto-generated method stub
mService = MainServiceImpl.asInterface(service);
}
};
}

I have tried setting intents all the ways, by this method, by method
as i mentioned in code, tried by calling setClassName. but i dont
think that does make difference.
