View 1 Replies View RelatedAndroid :: Need To Store _ Retrieve Vector In Sqlite Database
Sep 1, 2010I 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 RelatedAndroid :: Converting Byte Rgb_565 Array Into Argb Or Rgb Array
Jan 12, 2010I have Picture data in byte rgb_565 array, and I want convert it in a productive way into argb array. Right now I have found only one (little slow) way to do this: Bitmap mPhotoPicture = BitmapFactory.decodeByteArray(imageData, 0 , imageData.length);
where imageData is my byte[] array in rgb_565, and then: int pixels[] = new int[CameraView.PICTURE_HEIGHT*CameraView.PICTURE_WIDTH]; mPhotoPicture.getPixels(pixels, 0,PICTURE_WIDTH, 0, 0, PICTURE_WIDTH, PICTURE_HEIGHT);
The point is I believe creating a Bitmap object is exacting and not necessary in this case. Is there any other faster way to convert rgb_565 array into argb array? I need this because making image processing on rgb_565 array seems to be a little annoying. Or maybe it is not so hard?
Android :: Converting Short Array To Byte Array
Feb 16, 2010I am trying to make an application that would be able to send the user's voice over the network using RTP. I am using the ported stack from hsc (JLIBRTP) and I am able to record user's voice in a saperate thread. the problem is that jlibrtp uses has a class named RTPSession that is responsible for the session and has the sendData method that takes a byte [] as argument and the AudioFormat class I am using to record user's voice is in AudioFormat.ENCODING_PCM_16BIT wich is short. I have tried using 8bit audioformat but I get an illigalargument exception in my htc magic and in my emulator. So is there any way I can convert the short [] to byte [] ? would that be acceptable in order of voice quality?, is the above error a known bug for htc magic or the platform doesn't support 8bit audio format?

Oct 2, 2009I'm working on an Android application that stores data in a SQLite database. My question is, where does this database file get stored on the filesystem when you're using an emulator?
I have seen that it's stored in /data/data/package_name/databases
But I need to know where on my local machine's hard drive that actually maps to. The database persists on multiple runs of the emulator, even after having shut down the machine, so it can't just reside in RAM...

Aug 14, 2010I am an android application developer. I am developing an application which requires of me to use Sqlite database. I have implemented fetching the data, but i am facing problems when i try to insert data into the Sqlite database. The problem that i am having is that the new data i enter is not fetched, i.e nothing is new is being entered into the database.
this is the method i wrote in Data.java
myDataBase is an object of SQLiteDatabase
public void insertTitle(String Recipe)
ContentValues initialValues = new ContentValues();
initialValues.put(COLUMN_NAME,value);
myDataBase.insert(ZRECIPE, null, initialValues);
}
and i create an object "d" of it in Add.java, where i call the "insertTitle()" method. But nothing is inserted.

Dec 16, 2009I want to store location data in sqlite. A latitude coordinate is a double, with 15 point precision. As far as I can tell this corresponds with the 'REAL' datatype which is 8 bytes. The alternative I suppose would be to store it as a String, and simply convert it back into a double later. Does it make any odds which way I go? Are there differences in storage capacity / efficiency?
