Is there an intent that is fired when a user unlocks their screen? I want my app to adjust the brightness when the screen turns on, but the problem im running into is that the screen on intent is fired on the lock screen and it does not adjust the display on that screen.

I have a service which starts at boot up time, the service code needs the intent of following scenarios.
1) When the phone locks(after time out)
2)When the user unlocks the screen (by dragging the screen lock object)
There doesn't appear to be an API available where an application can be notified when the device is locked or unlocked. It is important the this application be notified of these events, since the service utilizes the proximity sensor which does not shutdown when the device goes into suspend. The app will need to unload the prox sensor manually to save battery when the device gets locked, and reload the prox after the device is unlocked again.
I was wondering if anyone understood how to make your application be displayed when you unlock the screen. I have an application where the user turns on a Bluetooth device, it connects to the phone, and the user should be presented with a UI. Having them hunt for the app or using the notification menu is not a workable option (too much work and not the obvious behavior).
The problem is that:
When the screen is unlocked:
- you can popup the activity from the background service when Bluetooth connects to a device
- User is happy because the UI is right there
When the screen is locked:
- The application gets started but is destroyed
- User unlocks the phone and nothing is there but the homescreen
One work around would be to disable the keyguard when the application gets woken up but the nuclear option is a pretty bad option. I know the standard Android assumption is that you shouldn't do this. In the normal case this behavior is fine, but in this case I explicitly did something I want the phone to respond without adding more work for the user to do. As per Google's guidelines if you don't like this behavior there can be an option for you to turn this off or you can not use the application.
A few more details, so after looking at this a bit more the problem isn't necessarily that you can't have an activity running when the screen is locked, unlock and expect it to be waiting. That does work if you do something like the following: lock your device run an app through Eclipse while the phone is locked/off unlock and it will be waiting for you.
But in the case the Activity is already running and I'm brining up a new window (which happens to be a transparent one, saying you're connected and asking what they want to do).
The problem is that it gets killed
CODE:..................
The setup here is as follows:
MyBackgroundService is a serivce that handles Bluetooth state (waits for connections, turns on Bluetooth if the user starts the app, etc.). It triggers a popup BackgroundPOPUP activity that runs a ViewFlipper.
MyBackgroundService starts BackgroundPOPUP through an intent.
BackgroundPOPUP is an activity with a Translucent theme (Theme.Translucent to be precise), it shows a ViewFlipper with some instructions and presents some options.
I have an already built application and I want to add a feature that has to be started when a call ends.
How can I achieve that?
I thought that declaring in my manifest something like this
CODE:............
Could be enough, but what kind of intent I have to put on the filter?
Looking in the documentation I found only the intents that detects when a call is started.
In my desperation with trying to get LiveFolders working, I have tried the following in my LiveFolder ContentProvider:Which, in all normalness, should launch the Browser and display the Google homepage when clicking on an item in the LiveFolder. But it doesn't. It gives a Application is not installed on your phone error. No, I'm not defining a base intent for my LiveFolder.logcat says:I/ActivityManager( 74): Starting activity: Intent { act=android.intent.action.VIEW dat=Intent { act=android.intent.action.VIEW dat=http://www.google.com/ } flg=0x10000000 }It seems it embeds the Intent I give it in the data section of the actually fired Intent. Why is it doing this? I'm really starting to believe it's a platform bug.update: I have filed an issue and removed the LiveFolders feature. I will include it in my app when I'll get a response either here or there that clarifies this thing. If I get the time I think I'll upload a demo app to that issue. Update: I have received a notification that the bounty is expiring in 3 days. No one wants it? Update 04/25/2010: I have updated the issue on the Android project and uploaded a test application. It would be nice if someone could test this application on a device, maybe it's such a subtle problem that it only appears on the emulator.

I have a user's twitter handle. Right now I'm opening it through a web page like:
String url = "http://www.twitter.com/" + "example_handle";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
If the user has the Twitter android app installed, is there a different intent I can use which gives the user the option to view that user's twitter feed in the Twitter app, instead of forcing them directly to a browser? I'm not sure if the author's of the Twitter app have exposed any such intent.
As in android, after inactvity of screen off timeout, android screen goes off. So here android itself uses some activity observer, to know whether user is currently active or not. I need not every keystroke or touch event with details, just knowing that user is active and getting a broadcastreceiver after some timeout value. Does anybody know something related to activity observing ? I got the code from in frameworks where it broadcast, but I am still figuring out code in android that monitors user activity.I am open to modify code frameworks too. || Hare Krishna Hare Krishna Krishna Krishna Hare Hare || || Hare Rama Hare Rama Rama Rama Hare Hare ||

I'm trying to configure proximity alerts that will be feed from a Database and webservice provider; but I have a problem configuring a simple proximity alert for testing. I manage to create the alert but it never gets fired, I'm only trying in the emulator for now and donīt know if I need some extra code to trigger the alerts. I've read somewhere that the GPS provider to disabled so the network provider can be used in order to trigger the alerts on the emulator.
My code looks like this:...................
Our app starts out with a tab activity. But, before the user can get into the tab activity to do work, we have to check to see if they're logged in. This login is required for all activities within the tab activity. So, instead of having this security check within all the activities, we created our own abstract "activity" and have the tab activities extending our custom activity. Our "security check" (just see if they have a login key and login token in Preferences) is put within the onResume() of the Abstract activity. If either of these checks come back false, we fire off the login activity and use dialog's within that screen.
(We're doing this because we don't want the user to be able to see the data on the tabs if they're not logged in, so this login activity is a black background with dialogs for username/password). The issue is, the onResume() of the abstract activity is being called numerous times, and starts the Login Activity multiple times. We've tried setting the "singleInstance" and singleTask flags on the xml for the login activity, but the activity ends up calling onActivityResult before it is even displayed on the screen.
implicit intent with class name as action defined in intentfilter. is not working. Only it it is defined as "android.intent.action." it is picked up ? is it so ?

I need to capture the absolute positions of some ImageViews to use as drop targets. I can't seem to find what event I need to put my code in to read the screen and get the Left(), Top() .. positions. I do not want monitor the inflation of each individual view. There must be some sort of onScreenFinsihed type of event, but I can't find it. onMeasure and onDraw seem to fire at the start of their work, I need to know when they are done.

The password screen locks and when it asks for the user name and password it states invalid user name / password!
Is this a known problem since when I called and talked to both Verizon and HTC the only thing they could tell me was to do a hard reset and they weren't aware of this problem?
I have a variation of the LG Ally called the Shine Plus. The swipe gesture on the main screen which unlocks the phone is completely bypassed when you open the slide-out keyboard. No matter how it's locked, anyone can access the phone by sliding out the keyboard. Does anyone else have this problem, and is there a fix for it?

This allows to trigger a custom Activity when this specific preferences item is triggered. Copying from the documentation, I'm using an implicit intent, and it's working. But I'd solve a problem if I could use an explicit intent, that is writing the fully qualified class name of the target Activity. I didn't find documentation about this, so I don't know whether it's possible and how to do that.
when a user leaves the current activity by pressing the home screen button, how can i make this trigger a method? This doesn't seem to call onResume(), onPause(), or onDestroy().

I'm new to android development. Is it possible for a view (with a particular layout) to "appear" at the location where the user "touches"? If so, how? Like the idea of right-clicking on your computer - a menu pops down wherever you right-click and when you navigate away, it disappears.
