POAndroid: How to communicate and exchange objects with a Local Service?
text
Body
copied!<p>So far I've a class for a simple local service. What I want to do is to <strong>send requests</strong> to this local service <strong>from different activies</strong> in my application. Depending on the parameters of these requests the service will connect via HttpClient to a webserver and receive a JSONObject and return it to the activity. All the HTTP communication is already working within my activity, but I'd like it to <strong>run in a separate thread in my local service</strong> now.</p> <p>The source code of my very simple local service looks like this so far:</p> <pre><code>// BackgroundService.java package com.test.localservice; import android.app.Service; import android.content.Intent; import android.os.IBinder; import android.util.Log; public class BackgroundService extends Service { @Override public void onCreate() { super.onCreate(); Log.i("BackgroundService", "onCreate()"); Thread thr = new Thread(null, new RunThread(), "BackgroundService"); thr.start(); } class RunThread implements Runnable { public void run() { Log.i("BackgroundService", "run()"); /* Here the HTTP JSON communication is going to happen */ //BackgroundService.this.stopSelf(); } } @Override public void onDestroy() { Log.i("BackgroundService", "onDestroy()"); super.onDestroy(); } @Override public void onStart(Intent intent, int startId) { Log.i("BackgroundService", "onStart()"); super.onStart(intent, startId); } @Override public IBinder onBind(Intent intent) { Log.i("BackgroundService", "onBind()"); return null; } } </code></pre> <p>The problem I'm facing now (due to a lack of knowledge) is the communication part <strong>Activities <--> Local Service</strong>. I found some communication and object exchange examples for a <strong>Remote Service</strong> using <a href="http://developer.android.com/guide/developing/tools/aidl.html" rel="nofollow noreferrer">AIDL</a> (Android Interface Definiton Language). However, I'm not sure if I've to go this path. I would simply like to exchange either my own defined objects or if that is not possible then just a JSONObject or if it makes things much easier even just simple String Arrays would work (for now).</p> <p>Can someone please point me in the right direction and if possible give a simple example of an Object exchange (both ways) with a local service.</p> <p>Thanks in advance.</p>
