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?

I'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.

Currently my mobile is running on android-1.6 and i have installed so many applications, some of them are dealing with the databases. If i update my mobile with android 2.1 version, will the data still remains same? What about the Preference variables information that are saved in the android phone memory if i do FACTORY RESET?
View 11 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.
Briefly, I need ONLY ONE of my apps to access the data mobile network while the other ones remain blocked but when I connect to a Wi-Fi I need them all to be connected, how can I do this?

View 1 Replies View RelatedI'm developing an application which downloads a file from FTP server. The code first checks if file is present on local system . If it is not present on local system then it downloads it from FTP server. Application must download file from FTP server when it executes first time after getting installed.
If we reinstall the application , android preserves the data of old application .So now application finds the file on local system and does not download it from FTP server. But it should always download the file on first execution after fresh install. Is there any way to completely wipe out the previous application data on fresh install? Is there any registry or some location where an application can store data and it gets automatically wiped out when application is uninstalled?
talk about limited information! I'm trying to get my Android application to connect to an online database to access information. There's quite a bit of info including geotags and these are going to be mapped on my app. The developer site has the very informative piece of information:You can use the network (when it's available) to store and retrieve data on your own web-based services.

View 10 Replies View RelatedI have an AppWidget which provides a summary of some data stored and controlled by my main Application. (In a similar way to a Calendar AppWidget showing the next event from the main Calendar application). I want to know the best practice for retrieving the data to update my widget. I have followed the example, and I have extended AppWidgetProvider and have a working widget, onto which I can update. I would expect to read the data from my main application and then update it via my AppWidgetProvider's onUpdate() routine.
Now, is the best practice here for my separate main application to provide the data via a ContentProvider? I assume so, as my Appwidget is not part of the same application. Is it possible to access a ContentProvider inside my onUpdate() routine? Before writing my main application content provider I started to test out retrieving some available data like Contacts information, and showing say a contact name in my widget, to show I can extract data from an existing ContentProvider. When accessing the Contacts contentprovider, the examples talk about:
1) Activity.managedQuery(), but my AppWidget is not an activity. 2) ContentResolver.query(), but I can't work out how to get a valid ContentResolver so I can access the Contacts. getContentResolver() does not appear to be defined for AppWidgetProviders. Am I approaching this the correct way?
There is no solution for this?

How do I find out if the activity is running and send data to it if it is?

View 4 Replies View RelatedI'm working on a widget that will change the data it is displaying when a user taps on it. This would normally be easy to deal with, but my app widget provider is handling multiple widget instances that have different sets of data. With that being said, when a user taps on the widget, a PendingIntent is launched that calls the changeData() method. Inside the intent that is launched is where I store the widget ID so changeData() knows which data set to use. At first I was storing widget IDs in the intent's extras, but I found out that there is a bug in how Android widgets handled widget intent extras so now I am trying to store the widget by passing a URL using the setData() method(formatted like content:widgetId I.E. content:24, etc.).
This is how I am setting the data for the PendingIntent:
Intent changeData = new Intent("com.tonycosentini.mintdroid.CHANGE_DATA");
changeData.setData(Uri.parse("content:" + currentWidgetId));
PendingIntent changeDataPendingIntent = PendingIntent.getBroadcast(this, 0, changeData, 0);
However once I try to test this, the onRecieve() method that is usually called when a widget is tapped is no longer called. Is there something I need to setup in my Android Manifest file for this work properly or is there something I'm doing completely wrong?
In Android can application send location data as MMS or SMS or any other means (e.g. email)?
View 2 Replies View RelatedI've noticed lately that some app recommender programs seem to get data off the android market. I'm wondering how I could retrieve information, such as screen shots, description, developer, number of downloads, rating, etc...
I've done many searches and I haven't found any solutions. It would be nice to be able to use that info to be able to see a rating for an app inside an app chooser, for example. Or perhaps be able to track changes and rating over time and version history, etc...
Is there an API to access that information? Is there a way to parse the data from a website? Or is there a complicated hack involved?
How to upgrade Android app without losing data ? e.g. I have a game which is using some preferences or sqlite data. which is associated with the android app. If app is already installed on device, it is not allowing the same app to install again. and one need to uninstall then reinstall app again.
so, if one wants to upgrade app with the older data then how will he be able to do it ?

I have an application that allows the user to "drill-down" into data. At each level of data the user can choose a Tableview item or a Listview item. This will result in a startActivity() call for display of new data.
I can get back to the top (Parent activity) by using the Back button, which can take a while. Is there a way to "POP" back to the Parent activity and dismiss all previously allocated activities, and not have to go back through all the activities previously created?
