I am developing an application that periodically sends information to an external server.I make a local copy of the data being sent, for backup purposes.What is the best option to store the data in terms of saving battery life? Each data submission is a serialized object (the class has 5 fields, including a date, numbers and strings) of about 5K-10K.Any other idea?

Please direct me to a description of the techniques that the ContentProvider employs to access data. I am trying to understand how it works as well as what is tunable or even if its meant to be tunable. It the memory management tiered, cached, virtual, flat? Is it file based, shmem based, stream based? Can there be a combination thereof?
Any information, suggestions, or references are welcome. The android fundamentals page says: "The data can be stored in the file system, in an SQLite database, or in any other manner that makes sense;" but the android ContenProvider page barely skins the onion.
Is there something like a FileDialog available? From previous threads, it appears there isn't one.
If not, has someone written one?

a) Specify a folder/filename on storage for creating an SQLite database.

View 1 Replies View RelatedI have an application with a lot of media data (images and videos) that were previously stored on the sdcard. With that, images and videos are displayed fine in my app.
Now, in order to secure the content more, I wanted to move the content to the internal storage / data dir of the app, which I did. I copied all media with a routine within my app to the data folder (/data/data/com.myapp/some/folders/video.mp4) and adjusted the path in my app so that it would look for the media in the internal storage data directory and not the sdcard anymore.
Everything works fine, images are being displayed (decoded) properly, but videos don't play. They files do exist though - I do not get a FileNotFound exception. But an IOException: java.io.IOException: Prepare failed.: status=0xFFFFFFFC
Why is that? Everything is handled within my one app and the videos have been copied with the same routine as the images, thus having the same permission settings. Looking at the stack trace, it all runs in process id 18060).
Why I cannot playback the video from internal storage? Or how can I?

View 1 Replies View RelatedI am preparing a new update of my application, in this version I need to insert lot of new rows (200) in my db.
Because I don't want to programatically add 200 insert code line for each row, I would like to know what is the best method to accomplish it just with a call to the file and dumping it into my db.
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 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?
View 3 Replies View RelatedI 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.
