View 2 Replies View RelatedI need to store an retrieve a vector of an unknown number of objects in an android sqlite database. Essentially, the setup is this: I am developing a task management app, where the user can add as many notes as they like to their tasks. My current setup uses one database, with one row per task. This presents a problem when I need to associate multiple notes and their associated information with one task. I can see two approaches: try to store an array of notes or a vector or something as a BLOB in the task's row, or have another notes database in which each row contains a note and it's info, as well the id of the task which the note belongs to. This seems a little easier to implement, as all I would have to do to retrieve the data would be to get a cursor of all notes matching a particular id and then iterate through that to display them to the user. However, it seems a little inefficient to have a whole new database just for notes, and it makes syncing and deleting notes a little more difficult as well. What do you think? Is it worth it to have a separate notes database? Should I use a BLOB or go for the separate database? If a BLOB, are there any good tutorials out there for storing and retrieving objects as BLOBs?

View 1 Replies View RelatedI have some reference data in a text file (~5MB) that I want to use with might android application.The file is of the format:
1|a|This is line 1a
1|b|This is line 1b
2|a|This is line 2a
2|b|This is line 2b
2|c|This is line 2c
What I want to know is the most efficient way (less memory, fast, size etc.) to use this file within my application.
a.) Should I save the file as a raw resource and open and read the whole file whenever I need a certain line.
b.) Should I convert the file to XML and use XPath to query the file when ever I need to look up a value
<!--sample XML -->
<data>
<line number="1">
<entry name="a">This is line 1 a</entry>
</line>
</data>
c.) Should I just copy & paste the whole file as a static string array in the application and use that.
[EDIT] I will also need to search this file and jump to arbitrary keywords e.g. "line 1a".

View 1 Replies View RelatedI have been facing problems to manage statics variables used in my android application. If we exit the application against a particular event (touch or key event -which is must for my app), all the statics variables are retaining the values when I am launching it again. I am invoking Activity.finish() method for termination . I know there is a collection type class available called Bundle and we can use it to save the states of all the statics and get those back when again creating the same activity during relaunch, but it would be a hard task if we want to port some j2me applications to Android because of having thousands of statics variables. Is there any way to kill the application completely including all the statics variable used there?
I tried with System.exit(0) and it works well for Android G1 and G2 (tested in firmware 1.6). But in Android Robyn (prototype) the same causes a major defect ("Activity not responding" popup apears just after exit) and I came to know from android dev forum that calling System.exit(0) is not recommended for termination of an activity.
I want to refer to a static Java variable in my styles.xml, is that possible? Here's a pseudo-xml example:
<style name="Artwork">
<item name="android:background">@drawable/border_{Constants.MY_COLOR}</item>
</style>
I have used some static variable in my application, i want to clear static variable value when will i close my application.anybody know please give solution for that.

View 1 Replies View RelatedThat's a lot of code... no time to read it over now.. but off the top of my head: look into either using a database, an Application class (that will run the whole time your app is alive), or adding extras to the Intent bundle before starting your subactivity. These are all methods to pass data around between activities.
View 4 Replies View RelatedI am new to Android, and I haven't developed any app regarding databases on Android yet. So I have a few basic questions. I am after a good database class sample, that will let me to run the CRUD operations. I would like to use it as a static class

If I have a bunch of data that is never going to change (eg. an English language dictionary or the rgb values of a couple hundred color names), how do I use an SQLite database to store it? I know a database is faster than loading everything into memory when the app starts, but how do I make the database either the first time the app runs or "before" the apps ever runs?

View 2 Replies View RelatedI'd like to use an existing sqlite3 database created outside of the phone, on a computer reachable by Wifi. I know how to download the file using Socket. The problem I see is that android.database.sqlite classes access databases only in /data/data/<package_name>/databases and it does not seem to be possible to write files directly in there. Is there a way to write a file in /data/data/<package_name>/ databases or ask the android.database.sqlite classes to read a database from another place?
