I see this has been mentioned before, but with no answers, so ive decided to make my own thread. I will be swapping my phone very shortly as it is damaged but I would like to save certain data from applications, such as game saved data and text messages from chompSMS.

i build application....and i want to back up my database when user click "clear data" in manage application... because data is lost...some data is very critical for process in my application...how can i solved this?
View 2 Replies View RelatedI'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.
View 3 Replies View Relatedto start with I've gone through the entire notepad tutorial, I'm a professional game programmer who has some extra time. (though most of my time has been in C++, I did take a year or two of Java classes in college, and remember some of it). I'm not sure the site is a good site to ask questions like this.. If someone has a Forum that might be a good place to ask these newbie questions, please feel free to point me in the direction. I've examined a few of the samples, and think I've a grasp of what I want to do. I've a three to four project plan for some Android releases to sharpen my skills, but since this is my first project and I have never really developed for a mobile phone or the android before, I'd like to make sure I have a solid plan.The first project is an example of the license plate game, however I want to do a few things to change it. Heck maybe when I'm done it'll become a bingo style game, with bluetooth connectivity, you never know. The base idea is I want to offer a list of states, with checkboxes next to them. so to do this, I'll be starting with a Linear List layout similar to the note pad example, and then have a row that is only a Checkbox. I can use text and call strike through if it's been checked off. Perhaps offer an option to not show them if they are checked.
But I want the list to be generated from a set of lists. Maybe all of America's states, maybe reasonable American states (no Hawaii, no Alaska) maybe a North American list, (add in Mexico and some Canadian provinces), a European list, who knows. I'd probably have to have a pop up window that lists all of the lists I suppose using a radiogroup of some sort. So then as far as the data, after weighing options I think best solution is to make a database with two fields, "checked" and "name".I figure I can use the menu for most of the user interaction (aside from clicking on stuff we want to check off) with maybe a few context menu items, I understand how to make all of those already so I should be good. The question I have is what is the best way to populate the lists? Should I create raw data, and have different files for all the lists? Or is there some other way to do this? I've seen this done on the searchable dictionary, but I'd like to hear what people who have actually generated the data like this before. In addition is there an easy way to look at the sql database these applications create, or do you have to run searches on them and output the data? Finally any other suggestion or advice? I definitely want to try to get something like this on the market so I can see the full life cycle and see if anyone actually likes it. (luckily there's not a plethora of them already) but I also want a few people to look over my code if they're willing when I'm done to make sure I've done this right or at least not missing any basic mistakes.
I want to add a flag that will tell how much time my application is running. This flag will have to stay even after the application is removed. And, if its installed back, i must have a way to recover this flag. What's a way to implement this?
View 8 Replies View RelatedI have created an activity that calls a service. This service receive an XML feed and parse the info. Each time I get the info for a new station i want to send the details (Name,Id,Location all as string) back to my main activity so it can load it inside a list view. When I run my code inside the main activity it works. When I move it to a service I cant send the data back. This is what I have tried. After getting the current station info from I do this: submit Station(namer, loc, ids, dis, types); then: private void submit Station(String names, String loca, String idss, String diss, String typess){Intent intent = new Intent(NEW_STATION_LISTING); intent.putExtra("Station Name",names); intent.putExtra("Sid", loca); intent.putExtra("StationLoc", idss); intent.putExtra("Distance", diss); intent.putExtra("Types", typess);send Broadcast(intent);}

View 2 Replies View RelatedI have a message application so that on view 1 is displayed a list of messages and when you go to view 2 (subactivity) you can send a message. I want the program to work so that when you hit the android back button, you can go back to view 1 and see the list of messages including the new message. Right now only the old data is displayed, and I noticed that displayContent() is not called when going back which I assumed it would. Is there any way to specify that when the back button is hit, to call displayContent() again on the previous activity?

How can I make it happen to retain data in all three cases (orientation is changed, HOME is pressed, Back is pressed) in a feasible way?

View 2 Replies View RelatedI am a bit new to Android. What I need to do is send data back and forth between an activity and a service locally. The information sent is sensitive and must not be able to be picked up by other apps. This excludes using broadcast and the onBind() function if I understand things correctly? So the activity needs to send some string parameters to the service. Also it somehow needs to tell the service which activity started it so the service can reply to the correct class since many different activities will use this service.
Once the service has fetched the information via a http request it is suppose to send that data (just a long string which will later be parsed) back to the activity that started it. How do I go about doing this? Using static variables/functions is not an option since again many actives will be using this service. Sure it would be possible to use a static array to hold the classes but that just seems ugly. It's only possible to send simple variables (not objects) via the intent? There must be a better way to do this.

View 4 Replies View RelatedIf apps offer updates that turn out to be crap can you get back your original app that worked better? For example handcent sms had new update that's getting a lot of people saying its "force closing", "slowing phone down", and adding cheeky "charges for some new crappy feature" when the app is meant to be free. I've seen this with many updates people not being to happy, so again, can I update an app and then get the previous version back if I'm not happy with it?

View 1 Replies View RelatedI've noticed that my mobile data is turning off by itself. Initially I thought it was JuiceDefender throwing a wobbly, but then I noticed that its event log was full of comments like "Mobile data is back under JD control" and something about reloading a profile. By watching the notification in the drop down menu I noticed that it was perpetually restarting itself.
I uninstalled it, and tried another app called 2x Battery and the same thing was happening. The data toggle in the setting menu of MIUI was greyed out to show data had been turned off, and 2x Battery stated that data had been toggled by the user.
It seems to be that a third party app is deactivating mobile data. Is there any app out there that can log when an app deactivates data, so I can find out the culprit?
Any application that switches the phone to silent and back again without having to press the on/off button please?
View 2 Replies View RelatedSay a user runs my app from the HOME screen. The app has 3 tabs. Say he/she selectes a different tab, so he/she is in a different screen (same task). Now - if the user presses BACK - the device returns to the HOME screen. If the user launches my app again - the default tab is shown. BUT - if the user presses HOME - the device returns to the HOME screen (same). If the user launches my app again - the OTHER tab is shown.
I understand (sort of) the logic - BACK returns to previous app, popping my app from the history stack, so when launched again - it is started from scratch. But this is confusing my customers - they say it's a bug ! They dont understand the different between two keys doing the same thing as far as they see (returning to HOME). Moreover - I see a different behavior with the built-in DIALER app - I change tabs, press HOME, launch the app again - and it starts with the default tab.
Does anybody have any insight as to why a game appliction would restart when exiting with the back button. It does not automatically restart when using the Home button to exit and this only occurs one time (after the second attempt to exit with the back button, it exits cleanly). Also, I can reproduce this consistently on the Motorola Droid, but have not been able to reproduce on the G1 or the emulator running 2.0. I've tried changing the launchMode of my activities, but have not found something that works. These are my activities:
1. Splash Screen, Single Instance, Main/Launcher 2. Help, Single Instance 3. High Score, Single Top 4. Preferences, Single Top 5. Options, Single Top 6. Game, Single Top, with SurfaceView
The steps to reproduce the problem are: 1. User starts application, launching Splash Screen Activity 2. User starts game, launching Game Activity 3. Game Activity launches Options Activity (for result) 4. Game Activity restarts with result and game begins. 5. Pressing Back Button returns to Splash Screen Activity 6. Pressing Back Button again, briefly shows home screen, then relaunches Game Activity which starts Options Acitivity 7. Pressing Back Button again finally shows the home screen
Either exit button or back button only can be implemented in my application. But i want both the implementations in my application
View 1 Replies View RelatedMy friend was talking to me about an application my friend has, or that it comes with the phone, but I can't seem to figure out a way to do it.
So the application basically sends the caller a customized SMS if you do not pick up the phone. Say you call me, and I didn't answer, the phone automatically sends the caller a text that you set up beforehand that could say 'I'm sleeping, I'll call you when I'm awake' or something along those lines.
Anyone know what it is or how to configure it if it comes with the phone?
I need to develop an application with downloads the data at the background and update about the progress in the front.
I guess this can be achieved using services and activity and passing data in between the. But, what I need to do is even if I hit back button and then start the activity again. It should check if the service is running or not. If service is not running it should start one else it should display the data from running service.
Something like music player where music is played by a service at a background and activity displays the information. Even on browsing through other activities of the application or hitting back, state of the music player is maintained.

View 2 Replies View RelatedFinally got Velocity installed and setup the way I like it. It's a tremendous improvement in overall performance compared to the stock. Kudos to Trident for taking the time to put this together for all of us. I only have one problem with it that I hope I can do something about or I may end up back on the stock ROM. Velocity comes with the latest Google maps version, which I hate because you can't clear the data so over time the app builds up more and more used space. Since I use the Google Maps Navigation pretty much everyday for work, that's going to be a small problem. Does anyone know if there is an app out there that allows you to clear the map data periodically? Or is there a way I can push the stock Map app into Velocity and do what I did before and simply ignore the update notices? I know I can just keep uninstalling it and reinstalling it periodically and i may end up doing that if there is no way to clear the data because I would really like to keep Velocity. I hope this doesn't come across as a knock on Velocity because it's not meant to be. I think it's a tremendous upgrade to the Ally and if it wasn't for my unique situation of using Google Maps so much, I wouldn't even be asking.
