Android :: UI Blocking On Intent Service?
Sep 14, 2010
I'm launching an IntentService using startActivity from inside the onClickListener of a button. startActivity returns immediately. No blocking there. But the button stays "pressed" until the IntentService finishes its work. In addition, the screen does not respond to rotation while the IntentService thread is running. I can see that it's a separate thread in the debugger but the UI seems to be coupled to it. As soon as the IntentService thread finishes, the UI is unblocked. Any idea how I can prevent this and let the UI continue?

I'm starting a service with an intent where I put extra information. How can I get the intent in the code of my service? There isn't a function like getIntent().getExtras() in service like in activity.

My IntentService is blocking my UI thread and I wanted to find out why. So I turned on profiling in the onStartCommand method of the IntentService and turned it off at the end of the onStartMethod. The working being done in between is web access with the Apache HTTP client.According to the profiler, the onStartCommand method of the IntentService is running on the main thread, not in a worker thread. Any idea what could cause this behavior?

Suppose that I installed app A and app B, app A has a main activity, and app B wants to show that activity by sending a intent. My question is that how android knows I have installed app A and is able to map the intent to its activity? Is there any windows-registry-like store saving such information?

Sorry for the newbie question, but does anyone know how I can check whether an IntentService is already running? I'm starting an IntentService from onCreate within a normal Activity, and that means that if the user minimises and maximises the application, it gets called twice. I'm wondering if I need to use something like the solution here http://bit.ly/du3VW5 or whether there's a simpler way.

I want to receive Intent "android.intent.action.SEND" in a Service. Is it possilbe to register for this Intent via registerReceiver() and get the Intent in Broadcast receiver in the Service?
Or is there any restrictions that "android.intent.action.SEND" can only be registered via Manifest.xml of an Activity and not in a Service?

Are there general advices when to use service and when to use intents?

Having trouble with permissions. The error I get is this: Not allowed to start service Intent { comp= {com.commonsware.android.service/ com.commonsware.android.service.WeatherPlusService} } without permission private to package I installed the WeatherPlus app from Mark Murphy's dev book. I'm trying to call his weather service from a different app. I think I have an issue with permissions, not really sure how they work. I thought that you could just make your own, and then check against it. With that in mind, listed below is the client manifest, followed by the service manifest. I called my permission "mypermission". Code...

Is is possible to send an object to an Android Service through an Intent without actually binding to the service? Or maybe another way for the Service to access Objects...

I'm posting this to share the lessons I learned while working with IntentService. IntentService has a single constructor that takes a string argument "name". The documentation has no description of what name is used for. In looking at the sources, I found that its only use is in naming the worker thread for the IntentService. This thread is named IntentService [name].
I initially implemented the constructor of the derived class to also take a String argument and passed it along to the derived class. This is wrong. This will cause the startService() call to generated a java.lang.InstantiationException in the application containing the service i.e. you don't get the exception in the application calling startService(). A clue to the actual problem is a little further up in the logs:"newInstance failed: no <init>()"
The derived class must have a Default constructor and that constructor must call super() passing a string for the name component of the worker thread name.
public class MyIntentService extends IntentService {
public MyIntentService() { super("MyIntentService");
} @Override
protected void onHandleIntent(Intent intent) {
// Handle events on worker thread here }

I have a Service defined in the manifest with an intent filter that refuses to match when specified as a String resource but works when the literal action is entered in the manifest. Is there any reason I should not be able to use a String resource with an action in an intent filter?

But i am getting the error i mentioned during the bindService call.

I am developing a call blocking application for android. What I've achieved so far is that my application gets informed whenever there is some incoming call. Now i want my application to handle the incoming call instead of default android application. So for this, i am trying to kill the android phone process. Please tell me can i do so. If not, then how can i reject the incoming call.

On the market, there's an application called App Protector, which seems to effectively block the launching of configured activities until a password is correctly provided. By default, it blocks access to itself (not very interesting), Settings, and a few others. I wrote my own app to launch settings (rather than doing so through the home screen) and App Protector continued to do the job it claims to do.
When an activity that is protected is started, App Protector's password input activity is shown instead. Once the correct password is provided, the activity that was started comes to the front.
First -- does anyone know how this app is able to get between the rest of the system and the activities it protects? I would like to do something along these lines in my own application as well. Perhaps this app is receiving a broadcast about other activities coming to the foreground, and when the foreground activity is protected, it forces itself to the foreground?
Second -- does anyone know how well this technique will stand up to attack? Are there other ways to circumvent, where start Activity(...) fails to? It seems that one could use adb to un install it, thus removing its protection easily, but if I pursue my plans here, the app will be a part of a device's firmware (which, I assume, offers some protection against its apps being installed?)

I'm trying to use the Mail client on my Hero to send emails, but it seems that Three is blocking port 25. I've asked my hosting company if they can allow me to use port 587, but in the meantime, does anybody know of how else I can send email from my Hero?

Is there a API for intercepting and blocking a call? What I want to do is to create app that autometically detect incoming call and based on the caller it either alert the user or don's alert the user. Like, if the number is stored in the phone book then alert the user other wise just send a message to the caller that the person is busy.

I have an Activity that implements a Gesture Detector to catch the user fling input for navigation to other screens. That was working fine - but - I recently updated a class that derives from my BaseActivity to add an onClick function and now that click event seems to block the onFling from being hit. The onClick is tied to a TextView area (in a LinearLayout) I have on my screen. The resultsClick method is wired to the TextView using its onClick property in the XML layout.
I've tried changing the return values in onSingleTapUp and onDown without luck. I've also tried adding log statements to all the functions below as well. None of them fire when I fling in the TextView area but they do on other areas of the screen.
Maybe I am using the wrong search terms, but I couldn't seem to find an example that addressed this - yet I'm sure this problem has been solved before.

I have someone who's calls I wish to block. No I don't want to forward him to voice mail (even though I already have). I want the phone's caller ID to recognize the caller and simply bloc the call (I don't want the phone to ring and I don't want it to accept any voice mails from this guy). I know google voice has this feature, but I don't want to activate the single number version of GV (I'm not ready to have only one number. I read a similar thread that was posted here some time ago, but there were no definitive answers on it: http://androidforums.com/support/6077-caller-id-based-blocking-call-forwarding.html. I was wondering if anyone was aware of any apps that could be used to block a specific incoming number, which could be installed without having to root the phone.

I would like not to read the messages from some preselected numbers. Some person is annoying me (as it always happens in life), and I dislike receiving stupid and incongruous messages from that person. How could I achieve this? I found apps for blocking calls, mostly for WM, but I here look a tool for my Android, and, moreover, for messages. (A call blocker would be nice too, though, but I did not find one, even by looking in older posts in this forum.
