My app schedules an alarm,with the alarm scheduled, what happens if I release a new version of my app, and the user upgrades the app? Will this alarm be removed? Or will it be left untouched, and fired as expected?

I'm well aware of onSaveInstanceState(Bundle b) and the corresponding onCreate and onRestore. What I want to do is persist the bundle somewhere simple where I'll only ever have one at a time. The functionality is to be able to resume a game from its previously stored state - not to be confused with restoring the activity during its lifecycle. I want to restore it AFTER it's been destroyed (think of turning the phone on and having a button on the game that says, "resume last game". My thoughts are that if I can just persist the bundle that I normally use for the instance state, then I should be able to reload it later upon user request. I don't want to use a provider because they seem way too over the top for what I'm doing.
View 4 Replies View RelatedI am creating a file in my Android application as follows:
code:..........
And I write to the file during the running of the app as follows:
code:..............
This works fine but when my app closes the file gets deleted and when the app is run again all the information I wrote to it is gone.
How can I make sure the file persists even after closure of the app?
Update:I have changed MODE_PRIVATE to MODE_APPEND and the problem is fixed.
I am building an app which uses a WebView. This app runs at startup. Is there a way to maintain the app running(persists) even if the user presses the 'Home' or 'Back' button? In other words,pressing the 'Home', 'Back' or the other buttons shouldn't close the activity.
View 8 Replies View RelatedI've been searching around and can't seem to find a way to do this properly. I am doing some tracking where I want to draw dots on a map overlay recording previous positions. When onDraw of the overlay is called it seems the canvas is cleared so I have to redraw all of the history on every invocation. This could result in several thousands of dots being draw over time which seems to not be very efficient. Is there some flag somewhere that I have not found which tells a map overlay to be persistent? Or is there some way I can save and restore the canvas so I'm only maintaining/drawing the current point on each onDraw?
View 4 Replies View RelatedI have a WebView. I'm not quite sure how caching works for it. Ideally I'd like to load a web page from the network once (images included), then from then on only ever load it from the local cache. I'm not sure if we have this level of control over webview. Will it at some point just auto-clear the cache? How could I tell? I need to be sure that it's really keeping the page cached between different runs of my application.http://developer.android.com/reference/android/webkit/WebSettings.html.

It works fine, but stops flashing after a while so if I'm not staring at my phone, I could miss the LED indicator and not realize I got a new email. Using the Gmail application (not the HTC email program).
What causes the LED to stop flashing after a while? Is it because the phone is going into a deeper sleep mode that I could configure, or is it because the flashing LED indications stop and there is nothing you can do about it? I checked under notifications and didn't see any setting for "duration" of the flashing LED indicator for emails.
Just downloaded the latest version of Titanium off the market and it now offers scheduled backups (not sure if this is only for the paid version).

View 5 Replies View RelatedAre there any apps out there that would allow me to have both gmail and exchange switch from "as mail arrives" to "manual" certain times of the day?For instance, I sit in front of my work computer most of the day and don't require immediate email to my phone, same with gmail.So from say 8-5pm I don't really need instant mail. Also, from say 11pm - 6am I also don't need instant mail since I'm sleeping :-)it would be important that this would be controlled by days (for instance, I would like to be able to schedule the instant mail off on Monday, Tuesday, Thursday and Friday from 8am - 5pm.

View 10 Replies View RelatedIn the description of how to add a list of options to an AlertDialog the official Android documentation alludes to saving a users preferences with one of the "data storage techniques." The examples assume the AlertDialog has been spawned within an Activity class.
In my case I've created a class that extends ItemizedOverlay. This class overrides the onTap method and uses an AlertDialog to prompt the user to make a multi-choice selection. I would like to capture and persist the selections for each OverlayItem they tap on.
The below code is the onTap method I've written. It functions as written but doesn't yet do what I'd hope. I'd like to capture and persist each selection made by the user to be used later. How do I do that? Is using an AlertDialog in this manner a good idea? Are there better options?

I bought a few apps in the Market and in some cases I noticed that the developers charged for updates. I would like to know if this practice is admitted and fair. I also would like to know if it is possible to have a clear notice about how udates/upgrades FOR EACH APPLICATION are dealt with in terms of charges to your credit card when you buy in the Market. I think this is essential if we want to improve the Market, put some order and make sure you can control what you pay once you establish a relationship with third parties through the Market and eventually guarantee the success of the platform. Are there any rules for developers/sellers in the Market in this respect? Can we read them?

View 6 Replies View RelatedI am trying to execute a {public void} method in Service, from scheduled TimerTask which is periodically executing.This TimerTask periodically checks a condition. If it's true, it calls method via {className}.{methodName};However, as Java requires, the method needs to be {pubic static} method, if I want to use {className} with {.dot}.The problem is this method is for notification using Toast(Android pop-up notification) and Status Bar.But for this to work, the method must not have {static} modifier and resides in Service class.So, basically, I want background Service to evaluate condition from scheduled TimerTask, and execute a method in Service class.Can anyone help me what's the right way to use Service, invoking a method when certain condition is satisfied while looping evaluation?

View 2 Replies View RelatedI want to have a free version and a premium version of the same application. When people buy the application, I want them to be able to "upgrade" without losing their data, i.e. the premium version should install over the free version.I want to use the same code base and just switch a setting to build the premium version.
Andoid Market does not let me convert a free app to a paid app, so the trivial option is not available.I am curious if someone has tried this successfully. How does Android Market identify an application - will it think that the premium version is a different app and just install it in parallel?
I'm wondering if it is possible for a firmware update to increase the current 15fps video recording. (I believe it's 15fps) Don't get me wrong the quality is watchable, but I'm just wondering if it is potentially possible for the firmwares (or custom) to actually up the framerate a tad?
