I have found next issue: I would like activate my midlet from background and paused state. I have tried to use Timer (and call mymidlet.resumeRequest() in it), but midlet still stay in bakground mode (it have no focus). I would like to use threads, not javax.microedition.io.PushRegistry . Is it possible or not? Please, advice.
If you are using a Nokia phone, the "paused" state is not implemented but you can put the app to background. You can not use a "requestResume()" to bring the app to the front. You can, however, call "Display.setyCurrent()" with a new screen to bring it back.
