I have developed an Android app. Now I want to perform a few operations (i. e. - Reset the settings etc.. ) at the moment the app gets uninstalled from the phone. Is it possible to reigster a listener or a function that is called at the moment the app is removed?

I would like to perform a task just before the phone is shut down. I thought that Application#onTerminate would be called but that does not seem to be the case. Is there a broadcast intent when the phone is going to shutdown? If not, how to run a task just before the phone is turned off?

However I was told I should not have the listener in the adapter violating mvc. how I can remove a task in my TaskListItem class. I got the method removeTask() in the adapter, but don't how I can use it in the TaskListItem class.
Code:
public TaskListItem(Context context, AttributeSet attrs) {
super(context, attrs);
mContext = context;

Is there an app for choosing which apps you want to use that are already open or whatever. Or is there a button you can press to bring up a task list like you do with you blackberry when u hold the blackberry key and the list of open apps comes out.

View 18 Replies View RelatedI've been using Task Panel X and Advanced Task manager to kill unneeded tasks and keep memory at a maximum.
Recently, every time I open Task Panel X and then revert back to Home screen I get the HTC logo and then a loading screen while the device sets itself. This happens even if I kill NO tasks.
So my solution was to uninstall Task Panel X and then use just Advanced Task Manager. All the sudden, same result.
Everytime I open either of these apps and then go back to home screen I get a BLACK SCREEN WITH HTC LOGO, THEN A BRIEF (10 SECONDS) LOADING SCREEN. THEN ALL IS NORMAL.

View 1 Replies View RelatedI don't know how to elegantly solve the following task:
I have several blocks of code (operation) to execute. Each block can return true of false to indicate that further execution is possible. Inside of each block I have to use asyncronous methods calls (Because Android is completeley asynchronous).
Example of processing operations (not working now as expected):
CODE:.......
The problem is that inside of the operation I need, for example, display AlertDialog and wait for the input. But after I call dialog.show() my method execute finishes and it returns incorrect result.
Example of the button listener, registerd with AlertDialog is below:
CODE:..........
How should I modify processing of operations to support asynchronous model of Android?
I have done socket communication in a single application it is working fine.
But my requirement is i have opened two emulators and i am able to send sms between those two.
Now i want to run server in one emulator(myavd-5554) and client on another emulator(myavd1-5556)
I have used the following code on Serverside public class TCPServerActivity extends Activity
CODE:............................
I want to invoke the haptic feedback buzz when my ImageButton is pressed, but I am not sure the best way to do it. I first checked that my button was enabled for that, and isHapticFeedbackEnabled() returns true.
Then I am calling performHapticFeedback() with the constant FLAG_IGNORE_GLOBAL_SETTING, as the docs indicate that will be used to override any global settings.
The doc is a little ambiguous, but it does imply that this is something I can call at any time, so I am calling it in the OnClickListener():
CODE:..........
I appreciate that it would be better to call it when the finger first touches the button rather than on the Click event, but I wanted to get it working to start with, before refining it.
Am I barking completely up the wrong tree, or should the above work when I click on the button, because nothing happens?
I know this was talked about before at different times but I still have 3 questions.
1. what is the difference between a task killer and a task manager?
2. should we be using one of these apps or not?
3. when you look at the awake time if it is like 70% or 80% and you aren't using the phone a bunch I take it that means something is running,how can you find what is running.and is the awake time that big of deal?
Looking for a guide on how to use task killer. I had task killer on and deleted it. I think I was killing tasks that were needed to keep certain functions running that I use frequently. If someone would take the time to help me understand how to use one, I think I would be much more successful with it.
example - text messaging just stopped ( werrent receiving them ) . Once I took task killer off, everything started working again.
I am using this code to send an email (with no errors in eclipse), but when I run it in the emulator, I get the "No applications can perform this action." error.String[] mailto = {prefemail}; // Create a new Intent to send messages Intent sendIntent = new Intent(Intent.ACTION_SEND); //Write the body of the Email String emailBody = ""; // Add attributes to the intent sendIntent.setType("message/rfc822"); endIntent.putExtra(Intent.EXTRA_EMAIL, mailto); sendIntent.putExtra(Intent.EXTRA_SUBJECT, "TrackMe Password"); sendIntent.putExtra(Intent.EXTRA_TEXT, emailBody); startActivity(Intent.createChooser(sendIntent, "Email sent.")); Do I need to install some mail app from it? I tried the K9 email app, installed it with adb, but I don't see any changes. Do I need to do something other than installing? Or is there another good program for it?
View 6 Replies View RelatedI cant figure out how to perform an onClick on my ListAdapter.
Here is my code:
CODE:.....................
I want to be able to click on an item from the database, then go into a view that only contains info for that item. My class currently extends ListActivity. I've tried OnItemClickListener, but I dont know what else to use to make it work.
I don't exactly know how android updates the applications. As far as I've read around here it keeps the SQLite database. So, imagine this scenario: one application that uses SQLite database for persisting data. After a while I release v2 which contains some database changes and I need to update user data in database. How can I make this during the update process ?
View 1 Replies View RelatedI am trying to find a way to goto a database located on the web perform 1 query and close the connection. I have not had any luck with finding an answer, and I really don't know how to solve this.
Internet connection is not an issue, nor is any security issues. Also this cannot be solved with an internal database and this must go across the web.

View 1 Replies View RelatedI want to be able to perform live demos of an app I've been working at conferences. There doesn't seem to be an easy way to get a video feed of what's going on onscreen onto a big screen. We've hooked up the screen capture utility of DDMS and keep hitting refresh. Its not ideal. I'm aware that there are more automatic solutions that continuously cause a refresh, but these don't really provide video, and I'd also like an audio feed. I can frame grab within my app pro grammatically, but the Android SDK's video encoder only supports capturing video feed from the camera. Any ideas? What's the best way to live demo Android apps to large audiences?

I looked around a bit on android's development site but haven't had anything that points me in the right direction. Does anyone have any ideas on where I should start with this or have any good links that might help?

View 1 Replies View RelatedI have an application that is performing HTTP Requests (specifically calling the FogBugz API) when the user clicks certain buttons. Right now, I am just creating a service when the application starts, and then calling different methods in that service to complete requests. However, when I do this, there is the usual hang in the UI thread. I have looked at AsyncTask, but am not sure it will do what I want to accomplish. Because I need to instantly parse the XML that the HTTP Request returns, I need to have a process that is able to return this data to the UI thread. Will ASyncTask be able to accomplish this, or is there some other way.
View 1 Replies View RelatedI am creating a program which requires me to change a setting in the program when the video reaches specific points (at 1/3 of the video's completion, 2/3's and on completion). Android has a built in callback method for completion so performing an action at that point in time is not difficult. However, I don't know how to go about checking when the video has reached 1/3 and 2/3's of completion.

View 1 Replies View RelatedWhat implications does upgrading an app have on stored data i.e. Preferences and database? Does the system perform a clean install of the new version(i.e. remove the older version and then install the new) or something else? What if the user wants to retain the stored data- say values in the shared preference or a sqlite database? How can I emulate this app-update-install scenario? If I have a version 'x' installed on my emulator and I do a adb install of version 'x+1' I am getting INSTALL_FAILED_ALREADY_EXIST error. Should I try hosting the new apk on a Web server, will the Package Manager take this as an update and do the needful?
View 2 Replies View RelatedAnyway, I just wanted for everyone to post their favorite Task Manager/Killer, and why, and if there are any flaws. I personally use Advanced Task Killer Free. It has a simple UI, and the when you select or unselect apps it remebers it so next time you launch the app you can only remove the apps that you usually do, and keep ones that always run. It doesn't slow down or break the system.
