Android :: Which Data Will Be Deleted If User Uninstalls Application

Mar 18, 2010

If a user uninstalls an app from his phone, which data is explicitly deleted? I know that preferences are deleted. What about files on the sd card and about databases created by this app? If the data on the sd card is not deleted how can I avoid cluttering the users phone if I write larger amounts of data, like images on the sd card?

Android :: Application That Allows The User To Drill-down Into Data

Apr 22, 2010

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?

Android :: Get Rid Of All User Data Of Application After Bigger Update

Apr 16, 2010

I completely revamped an app. Tested it for a while on my device and emulator. The app worked fine. However when I updated the app through the Android market, my users experienced crashes.Since there is no way to properly debug this procedure I asume the crash is caused by old data which is not being removed from the device (probably from the onsavedstate bundle?!).Is there a way to do a "clean/total" reinstall without having the user to do it manually?

Android :: Best Way To Store Application Data / When Data Stored / Data Format Could Change In Future Versions?

Mar 4, 2010

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.

Android :: Storing Data On SD Card In Froyo - Files Deleted When Upgrading

Jul 24, 2010

I have an application which resides on the phone memory but downloads large data to the SD card on first launch (the app needs to be able to work without an internet connection most of the time) When using the recommend directory given in Froyo it seems all files on the SD card are deleted when I install a newer version of the .apk. I'd preferably like the files removed on uninstall, but not on upgrade since the files on the SD card aren't going to change between application versions, and forcing the user to re-download a large file that is independent of the application version does not seem reasonable. At the moment it seems I'm forced to use a different directory to the recommended one in order to stop Froyo deleting all the files when the application is upgraded. Am I doing something wrong, or is this how it is supposed to work (I'm guessing it is)?

Android :: Can An End User Disable 2G Data / Or GSM Function?

Aug 9, 2009

Is there a way for end users to disable 2G data services (e.g. make the phone just a phone)?Or disable the GSM function as well (say, for a device used on a hiking trip as a GPS tracker, where there is no coverage)?
Is there enough control in the SDK to pursue writing an app with a control screen like: [x] Enable Voice (GSM) Enable 2G Data / Enable 3G Data (uses more battery than 2G) [ ] Enable Data When Roaming (may result in extra charges) [x] Enable WiFi [x] Enable WiFi even if device is sleeping [x] Enable Bluetooth [x] Enable GPS [ ] Airplane mode (disable all radios)

Android : Regarding Storing Of Data From User In Database

Aug 19, 2010

I am working on some sample programs, where i have to take the value from the user and store it in the database. I have used DroidDraw to create the XML code for UI.For now, I have just started with a textbox. So, I have to take the value from this textbox and store it in a database. I am using SQlite browser to create tables. I read in some forums, that one way of doing this.

1. Copy the db file in the asset folder of the android project and use the AssetManager class. But i am not able to figure out how to use the asset manager class here. Or if I could get some simpler suggestions on how to store the value from user into the database, it would be great.

Android : How To Add User Customized Data To Database?

May 9, 2010

I am trying to design a sqlite database that will store notes. Each of these notes will have common fields like title, due date, details, priority, and completed.

In addition though, I would like to add data for more specialized notes like price for shopping list items and author/publisher data for books.

I also want to have a few general purpose fields that users can fill with whatever text data they want. How can I design my database table in this case?

I could just have a field for each piece of data for every note, but that would waste a lot of fields and I'd like to have other options and suggestions.

Android :: Securely Store User Data On Device?

Apr 9, 2010

I'm writing an application wherein users will sometimes make orders through it. I want to give users the option to save their billing info (name, address, etc.) so that it can be quickly restored later if they want to make another order. The user will enter a password to secure the data. Obviously I can't just put this as a file on the device, as anyone can root/find the data. Is there a built-in Android method for storing secure data that is locked with a password? If not, what is a good place to start for storing this data securely using Java?

Android :: Advice On First Application (loading Data / Populating Data)

Jun 23, 2010

to 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.

Android :: Store User Settings In Application

I was trying to do it with Shared Preferences but am not sure if this is the best solution. I would appreciate any suggestion on how to store user values/settings in Android application.
