android-service

I am building a music player that uses a service for playback. I have an Activity UI that controls (play, pause, next, ...) the service. I want to update the UI from my service when the next or previous button is pressed. I thought of passing an integer value. Here is my code: I have used a messenger for communication. The code in my service looks like: enum Event { NextSongChanged, CurrentPlayingSong }; public synchronized void registerHandler(Messenger m) { clients.add(m); } private void emit(Event e) { for (Messenger m : clients) { try { m.send(Message.obtain(null, e.ordinal())); } catch

I've a serious problem with android sqlite database and concurrent writing. For better explanations, I will give you a real life example: I've an desktop widget, where I'm showing a list of items from my database (and on background I have DataService, which in regular intervals collects fresh data from my remote server, and update my database with them). So - when i click on some item in list, i need to update clicked item (=do write operation) in database. BUT when i click on item exactly in moment, when DataService is updating fresh data in my database, it of course logs an error like this:

I've read similar questions here, but am still not clear on a couple of things. Using a Library Project means that my overall project will have two manifests -- one for the library and the other for the "main" app project -- and I'm not clear what goes in which or if there is some redundancy. I'm developing an app widget with "lite" and "paid" versions, so will have almost all code in a library project. Being a widget, the library will have at least a receiver, a service, a configuration activity, plus a couple of other activities. So where should the full declarations of these components --

I would like to know if it's possible to use Firebase jobdispatcher to schedule an url hit and get the response in order to update the db. I would like it to run once per day at night. Does anyone know if this is possible? I can't find any good example of doing this. I already read android documentation and https://github.com/firebase/firebase-jobdispatcher-android#user-content-firebase-jobdispatcher- . I need to use Firebase jobdispatcher because I'm targeting API 16. Thanks in advance. UPDATE This is what I did to schedule it once per day. final int periodicity = (int) TimeUnit.HOURS

I have this application that needs to run a service (background) that beeps periodically. The phone needs to beep the entire day for 5 seconds every one minute (used a handler in the service). I have implemented this service which does this perfectly, but when the phone goes into deep sleep mode, the execution stops of this handler stops. Using this answer from the question in SO, I managed to use wake locks and it works fine. But when I explicitly put the phone in deep sleep mode, the handler stops executing. Where do I place the wakelock in the service. Code snippet below. public class

I am trying to spawn a service that stays alive all the time, even if the user closes the application. According to these threads Keep location service alive when the app is closed Android Service Stops When App Is Closed Android: keep Service running when app is killed this can be accomplished with IntentServices or Service.START_STICKY Yet, I tried both types of services without success. In other words, my services get killed when the app is closed by the user. Can someone point out if this is can be done and how? Here is what I have tried without success: With IntentService: public class
