Android :: How To Stop Service Method Of Calling Activity Class?
Jul 2, 2010I am trying to call my service class's stopService() method from my activity. But I don't know how to access stopservice method from my activity class. I have the below code but its not working. This is HomeScreen class:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
enablecheck = (CheckBox)findViewById(R.id.enablecheck);
enablecheck.setOnCheckedChangeListener(new OnCheckedChangeListener(){
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
// TODO Auto-generated method stub
if(enablecheck.isChecked()){
startService(new Intent(HomeScreen.this, AutoService.class));
} else {
stopService(new Intent(HomeScreen.this, AutoService.class));
} } });
}
This is Service Class:
public class AutoService extends Service {
private static final String TAG = "AutoService";
private Timer timer;
private TimerTask task;
@Override
public IBinder onBind(Intent intent) {
return null;
} @Override
public void onCreate() {
Toast.makeText(this, "Auto Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
int delay = 5000; // delay for 5 sec.
int period = 5000; // repeat every sec.
timer = new Timer();
timer.scheduleAtFixedRate(task = new TimerTask(){
public void run() {
System.out.println("done");
} }, delay, period);
}
@Override
public boolean stopService(Intent name) {
// TODO Auto-generated method stub
timer.cancel();
task.cancel();
return super.stopService(name);
} }
Android :: Can Service Report Back To Calling Activity With Status
Jun 29, 2010Is there a way that a Service can report back to the calling activity when the Service has reached a particular stage of processing? Consider a music player activity that initiates the actual music playing in the background as an Android Service. I want to detect and inform the Activity when the Service has reached the Mediaplayer's onPrepared. Is there a way that the Service can tell the calling Activity when the MediaPlayer's onPrepared is called, to let the Activity know that the audio is prepared and ready to play?I am basically looking to see if there is work around, rather than having a thread in the activity, pinging constantly to check if the Service has reached onPrepared.

View 6 Replies View RelatedAndroid :: Get Calling Context In Service
Aug 30, 2010So I'm working on a service that will handle requests to send data to a socket.I've done socket programming in a service before, but only within the same application. I'd like this to just sit and do nothing until any application wants to give it data to send. That's all well and good.I have register an intent filter and the usual stuff and can process the data. But I want to process the data coming from different activities in different threads (subsequent calls from the same application will be computed on the same thread).Is there a way to get the calling package or app or whatever? I'd prefer not to require passing in an identifier as an extra to prevent spoofing. (It's not a serious security concern, it's just each application needs its data processed in the order that it's received.)

Android :: Calling Method From Service Immediately
Sep 3, 2010I'm pretty sure that android services are going to be the end of me.I have almost no hair left after the last few days.At first I was having a heck of a time getting the service to bind on an onclick of a button, got that straightened out from help here yesterday. Now I actually want the service to bind in the onCreate() method of the activity. That part is no problem, works as intended.My service is actually a socket service to connect TCP sockets to a socket server that I wrote.If I put the call to the method from the bound service mBoundService.StartSocketServer() inside a button click, bingo, works great. But I need this to fire up immediately when the activity loads, so directly under my bindService() call within my onCreate() method of the activity.When I place the call to start the socket inside my onCreate() I get a force-close.
This method (StartSocketServer()) spawns a new thread then opens the socket on that thread to my remote machine.I'm guessing that the problem lies with the new thread generation before the activity fully loads not sure.LogCat is fairly cryptic here. It does say something about thread attach failed, then shows an uncaught handler exception that has "Caused by: java.lang.NullPointerException" within it.Again, if I put this call to the method inside a button click, I"m in business, if it's in the onCreate() it fails. Is there some way inside an activity (presuming that my assumption is correct that it needs to fully load before spawning a new thread) to call the StartSocketServer() after it's loaded: ala body.onLoad() in html?
Android :: No Value Being Returned With Ksoap Calling Web Service
Jun 3, 2010I have a .Net Web Service which returns a single integer value. When i call upon it from my application, no value is returned. Nothing at all really happens. I set up breakpoints and watched it's progress and it seems the problem is coming from when i get to this line:androidHttpTransport.call(SOAP_ACTION, envelope);
I have a hunch that my URL string is the problem. I've tried replacing the "localhost" in my URL string with my local and network ip with no luck. Whenever i replace the localhost with the ip in my browser i get Server Cannot Access or Unable to Connect pages. Does anyone know a solution to this problem?
Android :: Service Dies Without Calling OnDestroy
Dec 15, 2009A service is setup by an activity with startService(service_intent). This service is meant to run 24 hours a day. After some amount of time, 5 or 6 hours sometimes but its not predictable, the service is killed.In the database log, the destroyed message does not show up and the notification #1 is not cancelled. Android makes no attempt to restart the service. The database log will show the startup of the replacement service if I trigger it by visiting the activity. What can I do to keep this service running or at least get it restarted by android automatically?

Android :: Need To Take Into Account When Repeatedly Calling Same Activity?
Oct 28, 2010I am developing an app where a single activity is instantiated multiple times by itself. I guess you could think of it like a book where each activity is a page. At the end of the page (activity) the user presses a button to go to a new page. I fire off an Intent for the same Activity, but I push different data into the Bundle so that a different page is loaded. This works fine, and I like the fact that the user can back up to a previous point, but my question is whether this will eventually be a problem? What happens if this activity is instantiated 10 times, or 50, or 100? Will the device run out of memory, will GC come along and clean up old activities, or what? If GC does clean them up, what happens when the user presses Back and the previous Activity is no longer on the stack? Is it better to keep track of the user's path, finish() the activity, and override the Back button so that whether the user is moving forward or backwards, I only load a single Activity? Another approach I could take is to refresh all the data on the page so that it's still the same activity, but with new data. The Back button would not work as expected in this case.

Android :: Calling StartActivity From Outside Of An Activity Context
Oct 12, 2010I have implemented a ListView in my Android application.
I bind to this ListView using a custom subclass of the ArrayAdapter class. Inside the overridden ArrayAdapter.getView(...) method, I assign an OnClickListener. In the onClick(View v) method of the OnClickListener, I want to launch a new activity.
I get the exception:
Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?
How can I get the context that the ListView (the current Activity) is working under?
Android :: Calling Finish() After Starting A New Activity
Apr 26, 2010The first Activity that loads in my application is an initialization activity, and once complete it loads a new Activity. I want to ensure if the user presses 'Back' they go straight to the Launcher, and not the initialization screen. Side note, is this even the best approach, or would this be better done with some kind of Intent Flag?
Is it correct to call finish() after calling startActivity() on the new activity?
CODE:...................
I'm still taking in the whole 'Message Queue' method of doing things in Android, and my assumption is that calling startActivity() and then finish() from my first Activity's onCreate() will log each respective message in the message queue, but finish execution of onCreate() before moving on to starting the next Activity and finishing my first one. Is this a correct understanding?

Android :: Translucent Activity Not Calling OnStop On Exit
Dec 3, 2009I'm having this strange issue where upon exiting a subactivity that is translucent (android:theme="@android: style/Theme.Translucent" ) the onStop() method doesn't appear to be called. have a TimerTask that runs and is supposed to be terminated when the subactivity ends in the onStop() method, but I'm instead left with an orphaned thread running in the background. It go particularly bad when I ran the subactivity several times. When I revert to no theme, the onStop() method is called and the activity behaves properly. Is there something I missed about how Translucent activities'lifecycles differ from standard activities?
