Android :: How To Inform Your - Not Started - App From A Boot_completed Receiver
Jan 12, 2010
I have registered a BOOT_COMPLETED Receiver in my application, i want to listen for changes on SMS Database.
The BroadcastReceiver starts a temporary Service which registers the ContentObserver.
Now i want to notify my main activity (which is not started) that the Observer was registered successful.
(I want to do this, because if a user installs the app for the first time he don't restart his phone but needs the ContentObserver too. If you have another idea how to do that you can post it. I just want the information that the observer is registered already)
My idea was to notify the activity with a static attribute:
CODE:........
But i think that is not good and doesn't work because the activity isn't started and this is ignored.

I just want to get numbers of times to be used for each Activity.
So the very straightforward method I thought is increasing the count for an Activity when it was started. But how can I get the information?

I want to receive a broadcast receiver whenever any app is started.
for example: I have an app which has the broadcast receiver which listens for the app started event .
I installed this app on the device.
Now I have opened the Phone or Contacts app. Now my app which is listening for this kind of event(app opened or started) has to be invoked.

I upgraded my phone to 1.6 and the BOOT_COMPLETED event isn't being sent to my application anymore.
There's nothing in the release notes related to changes in this intent.
Can anyone enlighten me as to what needs to change in my application for 1.6 so I can get this event.
This is a critical fix for a production application.

When publishing an update on the Android Market, is there any way to inform users of fixes & new features? I just published my first app and am still getting used to everything about the experience, including being taken aback by the types of comments that some people post. But I am definitely impressed with the error reporting capabilities!

Maybe it's easy, but I couldn't really figure this out right so far... I got a BroadcastReceiver waiting to get triggered by the AlarmMangager - this works fine.
Now: because the event, if it occurs, needs to refresh some elements on screen of the main Activity, I would like to send an Intent from that background BroadcastReceiver to my Activity - but only if it is currently in the foreground, aka active.
If it is not running or not visible, I don't care - and the last thing I want to do is start the Activity by my intent! I handle repainting of the views in my onResume method, so I don't care at all.
EDIT: my BroadcastReceiver is waiting for alarms that must be notified to the user. So, it must be there and declared in the manifest. The problem is: it will have to decide whether the mentioned Activity is currently up in front or not.

My app has a 1*4 icon size widget. When a user tries to add a widget I provide with a configuration screen. and some data is collected - it is verified by the server - it is added to the local DB with appWidgetID as the key - all is good. when user hits save, if there is not enough space, he is given a polite toast - "No more room on this home screen". Now my problem is that the application is not informed of this. Application still assumes the widget was created and sits back and wait for the broadcast to update the widget after certain amount of time.
Can anyone tell me if i can find out via a broadcast or a call back or any method possible to determine if the widget was not successfully created, so that i can mark that record in my DB as deleted. Or better if i can know the space available beforehand via some magic ninja code. my whole application design is disturbed because of this problem.

Getting random notifications on my EvoLTE and I'm trying to figure out what is causing them without reviewing miles of logcat files. Is there an app that will create a log entry to tell you what is causing notifications?

trying to create a broadcast receiver which responds to system events and change system settings. I don't need any interaction from the user so I don't need an activity and have been trying to do everything through the manifest file. I've put a log event into my onReceive method but it never logs anything so I'm presuming my method is never called. I've tried this with both the 1.5 and 1.6 SDKs. I was hoping somebody could have a look at my code please and let me know if there are any problems.

I'd like to create an app for iOS that does VOIP, presumably by interacting with a website. I can start with Android too.Does anyone know of any tutorials, suggestions or libraries that would be of any use.(The app would need to be rewritten for BB and android eventually, too.)

My application is background application.It uses WIFI lock and INTERNET permission. It is doing some socket communication with a Remote Host PC and as well as with a local android application. It will start based on incoming SMS. While my application is running, I tried to use the browser application. Within a minute my application is getting crashed.(in DDMS log, I found the application process has died) And again I restarted my application, it is always getting crashed within a minute. I could not find the reason from the DDMS log. Someone can help me to figure out the problem.

I want a countdowntimer to halt on a menu and also when the user goes from that menu to another activity. When the user comes back from that activity or when the menu is closed, the timer should still halt. However when the user went to the home screen and clicks on the icon again, I want the timer to restart. So my question is, is there a way to detect if the user has just opened your application, or if the user comes back from another activity or menu?

Is there a way to do this?
Can you access the activity stack in a way to grab what activity came before the one now in view?
I have a situation where an activity needs to know where it was started from, so it knows what data to display in that current activity.

There's already been some discussion of this, in various lists and blogs. I finally got an AnimationDrawable to work, but I cannot start it from onResume. I can start it from a timer that onResume starts, or an onClickHandler.
I've poked around the source a bit and I can't figure out, specifically, what state the view has to be in, in order for the background AnimationDrawable to start.
Can anyone enlighten me?

I'm looking for something to get up and running quickly with Android development. Perhaps a great tutorial covering the basics. I see a lot of posts on getting started but the ones I have looked over so far aren't great. What do people here recommend?

I would like my app to do something when another application is opened.
The current approach I have taken is to create a broadcast receiver that monitors all
android.intent.action.MAIN
events, but either I am not doing it correctly or the way I am going about it is incorrect. The section of the manifest looks like this code...
I included the launcher category just as a test. GetApp currently is only set to make a log entry when called.

How can I know what Activity has started the current Activity? Is there any specific method like, i.e. getIntent().getCallerActivity() or the only way is saving some information within the Intent using putExtra()?

I've got a HTC Wildfire and in the last couple of days the battery has started draining really quickly. Usually I could leave my phone overnight with wifi and mobile web etc switched off and the battery would drain by a maximum of a couple of percent but now it's losing 25% of its charge overnight with nothing running. Looking at the battery usages since unplugged 3% is phone idle, 4% cell standby and 93% maps!! I haven't even used the maps for a couple of days so what could be causing this? The only apps I've downloaded in the last couple of days are WordUp!, Air Control Lite and Shopping List manager.

I have a main activity and a sub activity.The main activity starts the sub activity using startActivity, and passes an object in the intent.The sub activity reads the object out of the intent in its onCreate action.The sub activity updates the object, then returns to the main activity using startActivity, again passing the updated object back.However, the main activities onCreate function is not called, so the code it contains to read the passed object does not run.Further investigation indicated that the main activity onPause event is firing, i.e. it is only paused when the sub activity runs, so when the sub activity starts the main activity again, it just on Resumes.Does anyone know if there would be any disadvantages if I moved my data restore/store activities to the onResume and onPause events?I'm not using the onCreate saved Instance State, should I be?

I have a service that will monitor location changes daily. What I know so far that to start a service at boot, I have to follow the linked tutorial. This way I can get the service started at boot, but to save battery I need it only between 9am-9pm.
Question is pretty simple, so I will repeat:
How can I ensure a service is started at 9am and stopped 9pm every day?

I have a central activity that can be launched from two separate classes. I was hoping that in this central activity I could have an IF statement like
if(this.getIntent() == MainMenu.class)
{
// Do something here
}
But obviously that isn't legal so how could I structure an expression to check from what class an intent was started.
