Android :: Storing Double Values In SQLite / How To Ensure Precision?
Jun 21, 2010i have a problem with double values i need to store in an android homed sqlite database. since these double values represent gps values (lat & lng), i really NEED an absolute precision down to the 9th number after the comma.when reading lng from this table into some (java) double variable, i get a value like "0.999956837" - this renders the values pretty useless to me.is there a way to enforce the precision i need other than storing the values as "text" fields (what would make expensive casts neccessary) or storing them as integers (meaning i need to multiply/divide at each write/read-op)?

Jan 11, 2010I want to have some static numeric and text values as an application resource. For example my data is like this:
Levels 5 First_Level 500 60 1 Second_Level 500 80 1 Third_Level 200 60 1 Fourth_Level 130 30 2 Final_Level 100 30 3... and another 300 lines...
The format and order of the data is predefined and guaranteed to be valid.
I could read it with java.util.Scanner, but it's extremely slow in Android, reading a 10 KB file takes minutes. It's slow because of the regular-expression-based pattern matching inside (when I traceview'ed it).

Android :: How To Deal With Storing Bookmarks
Oct 13, 2009I am essentially using a listview but am looking at providing a bookmark functionality. I am thinking that I should store the item attributes in a file when bookmarked and retrieve when required to populate a bookmark listview.
I was wondering if there is a de facto standard used in achieving this or do I follow just the "writing into a file" and "reading from a file" when necessary style?
Android :: Utility For Storing A Static Map?
Feb 19, 2010I've got a common use-case wherein a user selects one item out of many (say, on a spinner or autocomplete list), then enters the data. For example, let's say the user selects a country. Ultimately, the data I want is the country code, not the country name; but the users will want to select based on name, not code. To put it another way, user's will select "United States", but I ultimately want that to translate into "US".
There are a lot of countries. Is there an easy way to setup a mapping in Android to hash from the name to the code? I've thought of a few solutions, none of them are quite satisfactory in my mind:
A database containing country/code, which I can query on. Setting up all countries as strings in strings.xml, then retrieving the resource by name. Creating a huge Map in code and using that. (This is the least satisfactory answer).

View 1 Replies View RelatedAndroid :: Storing Object Into SQLlite Database
Nov 16, 2010I would like to store an object into a SQLlite database. I am looking for how to best do it in order to ensure that if I need to updata/change this object in the future that users of the new and old object layout will be minimally impacted. In other words I want to ensure that making changes to the object will have minimum affect on clients that do not update their software on the old database format.
I want to also ensure an easy update from the old record style to the new format. I was thinking that I could add an element in the SQL row to identify the object type with a unique name, and to identify the object version number. That way I could read the row and use the object number to control the deserializer to use the correct version of the class.

View 1 Replies View RelatedAndroid :: Storing A Bitmap Into A ContentProvider From A BroadcastReciever
Aug 17, 2010I'm working on an app that, upon instillation of certain apps will send a message to them to register with a content provider. It all works fine, the strings are stored, but I can't get the byte[] blob (a bitmap .png file) to convert properly from within onRecieve() in the broadcastreciever.
CODE:.................
I hijack the context so that I can get a hold on the image from the getAppIcon() call (You extend this class which is an abstract class extending BroadcastReceiver) i.e.
CODE:......
But my understanding of the context is limited and I think this is what is causing it to be stored incorrectly.
I've also tried getting the bitmap from the resources when onRecieve() is called and that doesn't work either.

Jun 1, 2010I have about twenty pages of information that is stored in tables that needs to be stored in my Android application. Each column is a designated stop on a bus route and the column is filled with times that the bus will be at the stop. There is also certain information that needs to be associated with some times, such as if the bus is handicap accessible at a certain time.
Here is an example of one of the tables: Bus Times
I have thought about using a SQL lite as that seems as though it would be able to store these tables quite easily; but when I think of using SQL I think of dynamic data storage and this shouldn't be changing more than once a year.
Is SQL appropriate for this application? Is there a better way to do this?

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.

View 1 Replies View RelatedAndroid :: Storing A User Selection That Stores Itself For Use On Reload In App
Aug 2, 2010I've built a dialog that asks the user to pick a city from the list provided when the application first opens. The dialog works perfectly, however I want to store the user's choice so that when the app is opened a second time, it checks to see if the user has already made a selection previously. If they have, it doesn't display the dialog and defines the city variable as their previously chosen preference. And obviously, if they haven't made a selection previously (because its their first time opening the app or for some reason the app couldn't read the stored preference), it displays the dialog.
