I need to store data to use in my android program. Here are the details about the data: There will be one table. Each "row" of data will have a unique INT identifier. Other then that field, there will be four other INT fields and a text field. The string field will probably be a 2 or 3 sentences long. Each of the 4 INT fields will correspond to the ID of other rows.

I want to read data from database and displayed it in table layout form. table will contain n rows and 2 columns. But row size is not fixed then how to show them in table layout format?
View 5 Replies View RelatedHow do i efficiently copy a row data from one table to another table, where both of them are the same structure. i could go the much harder way of retrieving initial values from the row in the first table and then inserting to the second table. But i feel there is a more efficient way this can be done.

Create db ,table and insert data and retrieve it make it display in list.
I want my app to access database every hour and read next record from the table then update desctop widget and send notification. I know that there is AlarmManager which I can use to register my Intents but they are deleted when the phone is turned off or rebooted. Is there any other android class/service that I would update my application continuously even when I reboot my phone?

I have removed the news and weather widgets from my home screen and turned off "data enabled" and "background data" in settings/data delivery. I am around wifi all day so I can enable that if I want to download an app.Is there anything else anyone can recommend or will that stop the majority of back and forth data transfer from the phone?

View 6 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 2 Replies View RelatedThis is my first post. I've had a Moto Droid since day one, and I just love it. It is without a doubt better than any phone that I've had over the years, and that includes the iPhone, BB, etc.
However, there are 2 things that I don't understand - Font size and a spell checker. It is imposiible to read the small font size in emails or text messages.
1. Why has there not been an app to either change the font size or be able to zoom in? Picasy has incorporated multi-touch for zooming, so I've to assume that its doable! Why not have the same in an email client.
2. Why is there not an email client out there that allows for spell checking? There are many such apps for the BB! I am a terrible speller.
I am not complaining, I just want to understand the limitations from a developers prospective, as I am sure these isuues will eventually be addressed.

View 1 Replies View RelatedI'm getting hung up on how to handle the data for an app I'm designing. I want to pull a list of items from the net. The data is updated routinely, and I think it would be good to store all the data on the device so the app can load quickly and refresh the data in a background thread rather than have to wait for the network on every start-up.
I think I should make the data available in an XML and have a thread parse and save into a SQLite DB, but I'm not sure if that's the "best practice." Are there other ways that people go about handling this?

View 2 Replies View RelatedI have two files, one called "part1.txt" and another one called "part2.txt", which look like following
part1.txt part2.txt
lili like eating apple
lucy like playing football
Now i want to insert the contents of these two files into a single table with the schema
table_name(linefrompart1 varchar(100), linefrompart2 varchar(50))
My program reads the first file line by line and insert the data into the first column. But if it reads the second file and tries to insert the data line by line into the second column, it doesn't work the way i want. A table which i want should look like following
linefrompart1 linefrompart2
lili like eating apple
lucy like playing football
But instead i got the following table
linefrompart1 linefrompart2
lili null
lucy null
null like eating apple
null like playing football
Does somebody know how i can fix this problem?
I'm writing a content provider that returns data about game sessions. This data comes from an SQLite table. However, the client that consumes it will also want summary data: total wins, current/best winning streak, and so on. I'm not sure which approach to use.
* Possible Approach 1: Do nothing, let the client calculate what it needs.
The client could step through the whole table and calculate statistics itself. However, it's inefficient to send the entire database over the content provider link if the client only wants the summaries; this may also be prone to bugs because each client has to reimplement the summary calculations.
* Possible Approach 2: Separate content URIs for summary data.
The client could ask for a URI like content://myapp/summary/totalwins and get back a text/plain stream containing the number of wins. This seems like a big hassle to implement on both ends, though. Or it could ask for a URI like content://myapp/summary and get back an XML stream containing all the summary data, but this isn't much simpler.
* Possible Approach 3: A phony table.
The client could ask for a URI like content://myapp/summary and get back a cursor over a single row, with each summary value having its own column. This would not be an SQLite cursor but a custom in-memory cursor. It seems a little unnatural to use a table metaphor when there's always exactly one row, though.
* Possible Approach 4: The extras bundle.
Cursor has a getExtras() method that returns a bundle. The client could make a request for the main URI, content://myapp/sessions, and then just look at the extras bundle instead of reading any rows. However, there's no setExtras() method, so I'm stuck with whatever bundle object SQLite puts in there - and if it's Bundle.EMPTY, I'm out of luck.
