Android :: Service Callback To Activity
Jan 13, 2010Our application will expose a Service that can be called by Activities in other people's applications.In many cases, the parent applications calling Activity may be paused before our Service completes. I am looking for the best way for a Service to communicate back to the calling Activity that may have been paused.These are the known options:
(1) Require calling Activities to have a registerReceiver() with a custom action and broadcast to that from our Service. The only way to secure this registerReceiver() is with a signature-based permission.As our Service communicates with any number of unknown 3rd party apps,we can't sign our Service's parent app with all these unknown certificates. These apps would therefore be exposing an unsecured registerReceiver() on their Activity. Would ideally like to avoid requiring this.
(2) Create a PendingIntent to send results back to the activity and give it to our Service. Our Service would send data to calling Activity's onActivityResult(). Each time the result is delivered, the calling Activity will go through onPause() and onResume() but this should be OK.
(3) The calling Activities could create a Handler. The Activity would then create a Messenger pointing to that Handler and send it to our service. Our Service can then use the Messenger to deliver our message back to the calling Activity.
Android :: Starting An Activity From Callback Class
Aug 18, 2010I have an activity class(Application Class ) which calls a service class(Service Class) and closes. The service class takes about 5 seconds to complete its task and calls a method which is present in another class(Callback Class). Now according to the result, the callback needs to notify the Application class.Once i get the callback from the service, I tried calling a method defined in the Application class. In this method i create a new intent of Application class and call startActivity(Application Class). But this is not working. Can anyone tell where i am going wrong and what can I do to solve this issue.

Jun 3, 2009I want to find the dimensions of the various views in my layout. My understanding is this can only be done after layout is completed since layout is somewhat dynamic. So, after the activity calls setContentView() and then returns control on the main thread to the OS so that layout can occur, how do I get a notification that layout has completed so I that I can query the views for their dimensions? On a related topic, can I find out the status bar's height or least the screen's full size (from which the status bar's height can be calculate by subtracting my window's height)?

Dec 2, 2009I have an Activity which has no window (but it has a view). I'm using: getWindowManager().addView(view, params);I've attempted to call takeKeyEvents(true), however I see that takeKeyEvents first retrieves the Window and then calls takeKeyEvents on that Window.In my case, the Window is null.What this means is that I never receive onKeyUp and onKeyDown calls, which I need in order to intercept some key presses from external input devices (similar to a handsfree set for example).

May 31, 2013My goal was to find an android app similar to PC Internet Download Manager.I have found some good apps that can capture and download streaming media files from the browser.Some of them require Adobe Flash Player. These apps can download flv, mp3, mp4, etcThe apps in this list has their own integrated browser to be able to capture media files while streaming.
Here is the list:
-Media Grabber - Good but has little features.
-AVD Download Video Downloader - Great but can't capture every files.
-Flash Browser - It's in public beta, so it won't work for all devices, mine included.
-Vget - It can only download flash videos and not stream.
Are there any other similar apps that you know? Plugins? Other methods to download streaming files?

Aug 12, 2010I'm working on an app that launches the browser activity to perform a Twitter OAuth authorization. This process uses a callback url which will re-launch the activity that started the browser activity in the first place.My problem is that the browser pages remain in the history stack and when the user then clicks back from the preferences activity that launched the browser in the first place, they don't go back to the app's main activity, but instead are brought back to the browser. I've tried adding flags to the launching intent to prevent history and reset on clear, but it doesn't seem to work when running on my phone, only on the emulators.

Sep 21, 2009So I read through the SDK docs and I thought that calling a new activity(browser) as part of a task (myTask) will mean that activity* (browser) will close when a user closes the task (myTask) But I am left with a browser window.
Here is my scenario (in sudo code);

Question 1: What is the cleanest way to ensure that when a user closes my app, any outside activities called will be closed to.
Question 2: Does a callback URl start a new Task, or use one in the stack if available?

Android :: GPS Callback Off UI Thread?
Jul 6, 2010I'm having trouble getting the GPS's onLocationChanged to run on a different thread. I understand how to manage UI thread when I'm calling a function but with the GPS, I don't actively call the function.
My intent is to have a light flash every time the GPS receives a reading. I have put this function in a Runnable. I passed this function to a class that implements LocationListener. Then in the main class, I started a new thread that calls requestLocationUpdates. I was hoping that onLocationChanged of the LocationListener would run in a different thread, post to the callback and make the necessary UI effects in the UI thread. Unfortunately, the program crashes every time it tries to call requestLocationUpdates. What's the proper way of doing it?
Right now it looks something like this
Main class:
CODE:................
LocationListener class:
CODE:...............
The exception says Can't create handler inside thread that has not called Looper.prepare()
Android :: What Is A Binder Callback
Aug 31, 2010I have been watching the Google I/O presentation by Virgil Dobjanschi on the correct way to implement REST on Android with services and content providers. http://code.google.com/events/io/2010/sessions/developing-RESTful-android-apps.html
Based on the video I'm doing things the wrong way, which is not surprising given how hard the right way is. Anyway, having been shown the promised land in the video I'm having a bit of a problem figuring out how to get there.
I have most of it nailed but the one thing that's defeating me is the Binder Callback that Virgil references in the slides (see link above), on page 43 it shows step 2 as starting the service with startService( intent ) and step 10 as returning status information using a Binder Callback. There is no example code anywhere in the presentation which is rather frustrating. There is talk of open sourcing the Twitter client which apparently uses this approach but nothing yet and the announcement was in April.
In the video he states: "What is a binder callback? A binder callback, think of it as an interface that was passed in the request intent."
I have searched all over the place but have not been able to find any doc or examples that show how to pass a callback as part of an intent. Nor can I figure out any other way of passing in a callback.
I thought he may be referring to binding to the service and implementing the callback that way. However, he is specifically referring to a local service and using strarSerice() and not bindService(). Also with bindService() the service will be destroyed if the activity is destroyed which defeats the idea. The workaround is to use startService() and then bindService() and leave the service running for the duration. The other problem with bindService() is that the callback can not be use until onServiceConnected() completes which complicates the code even further as the action instructions can not be passed in the intent because the return callback may not be in place in time to return the results.
