问题 Please correct me If I am wrong : 1) A Service is used to perform long tasks in background. A service runs in the UI thread so if there comes a long task then it may freeze our UI. A service will continue to run independent of application as long as we tell it to stop. 2) An IntentService on the other hand is used to perform short tasks in separate thread. It automatically terminates when it finishes its task. What I have to do : 1) check for location every 5 seconds 2) if there is a change

My sample code is as follows package com.example.deneme; public class AndroidNotifyService extends Activity { /** Called when the activity is first created. */

问题 I want to develop an Android Service app that dispatches KeyEvents to the foreground application. Somehow, it would be like this I cant seem to find a way how, I am only familiar with the activity dispatches KeyEvents to itself, like this: @Override public boolean dispatchKeyEvent(KeyEvent event) { if (event.getAction() == KeyEvent.ACTION_DOWN) { if (event.getKeyCode() == KEYCODE_1) { // Do something } else if (event.getKeyCode() == KEYCODE_2) { // Do something } } else if (event.getAction()

问题 I have an application, that has a main.java file that sets up an alarm to call a recurring service. However when I close the application the service is no longer called for some weird reason. So I was reading around what I should be doing for my application (basically what I want is something like Twicca, where the twitter app continues to run even if you close it from your "task manager"). And it looks like what I need to do is deploy my entire application as a service, so that it will keep
