Show notification from background started service

So i'm using asmack library to listen for incoming xmpp packets. I've got the service implemented. It's started, bound, a method is run and then it's unbound. The service creates a PacketListener to get incoming messages, and displays a notification when a new message comes in. This all works while the app is the active activity, but doesn't work when it's fully closed (swiped away in the window list) and it's just the service running, the PacketListener doesn't fire. It fires as soon as the app is reopened though, firing off all notifications. I'm looking to get those notifications fired as they come in, instead of the service being suspended, if you will. The code for the service is here:

message.setRecipient(Preferences.Account.getUsername() + "#"

String fullSender = m.getFrom();
String address = fullSender.substring(0, fullSender.indexOf('/'));
message.setSender(address);
message.setContents(m.getBody());
Program.showMessageNotification(message, 9127);
}
}
}
}
and the code for the starting/binding the service is here:
public static void init() {
if (!initialized) {
// Call other portions of init code first
SmackAndroid.init(context);
Preferences.init();
// Set up our variables
contacts = GlazedLists.threadSafeList(new BasicEventList<Contact>());
// Start up the xmpp connection
Intent ixmpp = new Intent(context, XMPPService.class);
context.startService(ixmpp);
context.bindService(ixmpp, xmppConnection, Context.BIND_AUTO_CREATE);
initialized = true;
}
}
So as I said, i want to receive notifications from the service running in the background when the foreground activity is closed. Is there any way of doing this? Maybe have it in it's own process? Something else?
EDIT: the ongoing notification sticks around and works when clicked, in case you're wondering

use startforeground method
http://developer.android.com/reference/android/app/Service.html#startForeground%28int,%20android.app.Notification%29
in onCreate of service
public void onCreate() {
startForeground (int id, Notification notification)
}

Browser.BOOKMARKS_URI is no more?

I am trying to add content observer for AOSP Browser's history provider i.e., with Uri Browser.BOOKMARKS_URI. If I attach an observer, the onChange(boolean) gets called on my ICS running my Samsung GT-S7562, my JB running Samsung GT-I8262 or HTC Desire X but I don't get any notifications for AOSP Browser provider on my friend's Android 4.3 running Samsung SM-G7102. However for Google Chrome's provider, i.e., residing at content://com.android.chrome.browser/bookmarks, I get notified for changes on all android releases. Also if I query the AOSP Browser database & scan for entries, it only returns those opened in Chrome (I mean it returns Chrome's history in Browser.BOOKMARKS_URI provider).
Below is the sample service I tested for reference which is not actually required (don't mind but I think everything is quite clear above already):
package vpz.hp;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.database.ContentObserver;
import android.net.Uri;
import android.os.Handler;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;
public class Watcher extends Service {
private Provider Browser;
private Provider Chrome;
#Override public IBinder onBind(Intent intent) {
return null;
}
#Override public void onDestroy() {
if (this.Browser != null)
this.Browser.Stop();
if (this.Chrome != null)
this.Chrome.Stop();
super.onDestroy();
}
public final int onStartCommand(Intent Intention, int StartId, int Flags) {
this.Browser = new Provider(super.getApplicationContext(), android.provider.Browser.BOOKMARKS_URI);
this.Browser.Start();
if (Search(getApplicationContext(), "com.android.chrome")) {
this.Chrome = new Provider(super.getApplicationContext(), Uri.parse("content://com.android.chrome.browser/bookmarks"));
this.Chrome.Start();
}
return START_STICKY;
}
private static final boolean Search(Context Sender, String Package) {
try {
return Sender.getPackageManager().getPackageInfo(Package, PackageManager.GET_ACTIVITIES) != null;
} catch (NameNotFoundException Error) {
return false;
}
}
private static class Provider extends ContentObserver {
private Context Sender;
private Uri URI;
public Provider(Context Sender, Uri URI) {
super(new Handler());
this.Sender = Sender;
this.URI = URI;
}
#Override public void onChange(boolean Self) {
String Message = this.URI.toString() + " onChange(" + Self + ")";
Toast.makeText(this.Sender, Message, Toast.LENGTH_SHORT).show();
Log.e("VPZ", Message);
}
public final void Start() {
this.Sender.getContentResolver().registerContentObserver(this.URI, true, this);
}
public final void Stop() {
this.Sender.getContentResolver().unregisterContentObserver(this);
}
}
}
I have added below permission(s) already in the manifest:
<uses-permission android:name="com.android.browser.permission.READ_HISTORY_BOOKMARKS" />
Is content observer on AOSP Browser has been deprecated?

ending call in android using telephonyserivce.endcall()

I am working on app where i want to end outgoing call.
this is the main class
import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
public class phonecalls extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
call();
}
private void call() {
try {
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:123456789"));
startActivity(callIntent);
} catch (ActivityNotFoundException activityException) {
Log.e("dialing-example", "Call failed", activityException);
}
}
}
and outgoingclass is this
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.widget.Toast;
import com.android.internal.telephony.ITelephony;
import java.lang.reflect.Method;
public class OutgoingCallReceiver extends BroadcastReceiver {
private final String TAG = "CallControl";
Context context;
String incomingNumber;
ITelephony telephonyService;
#Override
public void onReceive(Context context, Intent intent) {
TelephonyManager tm = (TelephonyManager) context .getSystemService(Context.TELEPHONY_SERVICE);
try {
// Java reflection to gain access to TelephonyManager's
// ITelephony getter
Bundle bundle = intent.getExtras();
if(null == bundle)
return;
String phonenumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.i("OutgoingCallReceiver",phonenumber);
Log.i("OutgoingCallReceiver",bundle.toString());
String info = "Detect Calls sample application\nOutgoing number: " + phonenumber;
Toast.makeText(context, info, Toast.LENGTH_LONG).show();
Log.v(TAG, "Get getTeleService...");
Class c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
m.setAccessible(true);
telephonyService=(ITelephony) m.invoke(tm);
telephonyService.endCall();
} catch (Exception e) {
e.printStackTrace();
Log.e(TAG,
"FATAL ERROR: could not connect to telephony subsystem");
Log.e(TAG, "Exception object: " + e);
}
}
}
But the call is not ended even though i am able to print no. when outgoing call starts which show broadcasting receiver is working right .
Any suggestion

Yes definately there is two way to do it either using airplane mode or internal telephony for this . I used internal telephony and code I developed is uploaded here https://github.com/deependersingla/end_calls.
If you need anything more tell me , will be happy to help.

JmDNS Error - The method getInetAddresses() is undefined for the type ServiceInfo

For some reason it doesn't like the getInetAddresses() method in the lines:
Enumeration additions = (Enumeration) ev.getInfo().getInetAddresses();

});
serviceInfo = ServiceInfo.create("_test._tcp.local.", "AndroidTest", 0, "plain test service from android");
jmdns.registerService(serviceInfo);
} catch (IOException e) {
e.printStackTrace();
return;
}
}

Try download and use latest version of JmDNS from Maven Central Repository, apparently there are some issues related to the jar file downloaded from their SourceForge home page. jar file from SourceForge doesn't play quite nice with Android.
Check out this SO question for more details. Hope this help.

Can Android's ServiceTestCase<MyService> send Messages to my service?

I want to test my bound service with ServiceTestCase.
The testing consists of binding to MyBindServer, and sending a Message.
Watching the logs, you can see the service is started when onBind() is called,
and a message is sent from testAHello(), but, the server's handleMessage() is never called.
From the logs:
I/TestRunner( 2099): started: testAHello(com.inthinc.mybindserver.test.MyBindServerTest)
I/MyBindServerTest( 2099): setUp()
I/MyBindServer( 2099): onBind, action=com.inthinc.mybindserver.START
I/MyBindServerTest( 2099): testAHello
I/MyBindServerTest( 2099): sending SAY_HELLO
[here is where I expect to see the output from handleMessage()]
I/MyBindServerTest( 2099): tearDown()
I/TestRunner( 2099): finished:testAHello(com.inthinc.mybindserver.test.MyBindServerTest)
I/TestRunner( 2099): passed: testAHello(com.inthinc.mybindserver.test.MyBindServerTest)
Here is the code for MyBindServer.java:
package com.inthinc.mybindserver;
import android.app.Service;
import android.content.Intent;
import android.os.Handler;
import android.os.IBinder;
import android.os.Message;
import android.os.Messenger;
import android.util.Log;
public class MyBindServer extends Service {
static final String TAG = "MyBindServer";
public static final int MSG_SAY_HELLO = 1;
final Messenger mMessenger = new Messenger(new IncomingHandler());
class IncomingHandler extends Handler {
#Override
public void handleMessage(Message msg) {
Log.i(TAG, String.format("handleMessage, what=%d", msg.what));
switch (msg.what) {
case MSG_SAY_HELLO:
Log.i(TAG, "hello");
break;
default:
super.handleMessage(msg);
}
}
}
#Override
public IBinder onBind(Intent intent) {
Log.i(TAG, String.format("onBind, action=%s", intent.getAction()));
return mMessenger.getBinder();
}
}
Here is the code for MyBindServerTest.java:
package com.inthinc.mybindserver.test;
import com.inthinc.mybindserver.MyBindServer;
import android.content.Intent;
import android.os.IBinder;
import android.os.Message;
import android.os.Messenger;
import android.os.RemoteException;
import android.test.ServiceTestCase;
import android.test.suitebuilder.annotation.SmallTest;
import android.util.Log;
public class MyBindServerTest extends ServiceTestCase<MyBindServer> {
private static final String TAG = "MyBindServerTest";
Messenger mServer = null;
public MyBindServerTest() {
super(MyBindServer.class);
}
public MyBindServerTest(Class<MyBindServer> serviceClass) {
super(serviceClass);
}
#Override
public void setUp() {
try {
super.setUp();
Log.i(TAG, "setUp()");
Intent bindIntent = new Intent("com.inthinc.mybindserver.START");
IBinder binder = bindService(bindIntent);
assertNotNull(binder);
mServer = new Messenger(binder);
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
public void tearDown() {
try {
super.tearDown();
Log.i(TAG, "tearDown()");
} catch (Exception e) {
e.printStackTrace();
}
}
#SmallTest
public void testAHello() {
Log.i(TAG, "testAHello");
assertNotNull(mServer);
Message msg = Message.obtain(null, MyBindServer.MSG_SAY_HELLO);
Log.i(TAG, "sending SAY_HELLO");
try {
mServer.send(msg);
} catch (RemoteException e) {
e.printStackTrace();
}
}
}

I was able to get this working using the procedure below..anyone is welcome to chime in if this is incorrect, but the example above works (i.e. MyBindServer's handler receives messages)
It seems as though ServiceTestCase's bindService() method intends to act like a local service. In this case, the goal is to test as a separate process, which means using the following instead of ServiceTestCase's bindService:
Intent bindIntent = new Intent(<registered intent>); //Where registered intent is declared in the manifest file
getContext().bindService(bindIntent,mConn,Context.BIND_AUTO_CREATE);
where mConn is a ServiceConnection object implemented to do whatever your test needs it to do, in the case above, set mServer.
With the above, MyBindServer's handleMessage() is called for the testAHello() test.
UPDATE: I have noticed that depending on how quickly the test processing is done, teardown() can be called before the binding is ready to use. In the case above adding control variables to throttle the program flow based on mConn's onServiceConnected being called provided consistent results.
E.g.
protected boolean bound = false;
protected boolean processed = false;
private ServiceConnection mConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className,
IBinder service) {
Log.i(TAG,"Service conn");
mServer = new Messenger(service);
if(mServer != null
&& mServer != null){
bound = true;
}
processed = true;
}
#Override
public void onServiceDisconnected(ComponentName name) {
// TODO Auto-generated method stub
Log.i(TAG,"Service Disconn");
}
};
Then add:
while(!processed){
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
to testAHello()
