Android :: File Dialog - Allow User To Specify Folder/filename On Storage For Creating An SQLite Database

Jan 19, 2010

Is there something like a FileDialog available? From previous threads, it appears there isn't one.

If not, has someone written one?

I want to allow a user to

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

b) Specify an existing file/folder on storage card for opening as an SQLite Database.

Android : ContentProvider Storage/memory - Data Can Be Stored In File System - In An SQLite Database

Oct 20, 2010

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.

Android :: Thread-safety When Creating Methods - Activities Which Interact With SQLite Database

Sep 20, 2010

I am creating an app which allows for many different Activities to be started from a TabActivity(up to ~25). Most of the activities require data from the sqlite database, so when onCreate is run, an AsyncTask creates an SQLiteOpenHelper object(which will open a readable/writable database), runs a query, data is retrieved, and everything is then closed.

I was just testing messing around to see if i could break something, so i added every Activityto the TabActivity's TabHost. I then started mashing each tab as quickly as possible.

I noticed that very quickly i began to see in the LogCat: Caused by: android.database.sqlite.SQLiteException: database is locked: BEGIN EXCLUSIVE; and the app proceeded to die.

Typically there will only be about 4-6 tabs(i can just limit the user anyway) for the TabHost. I haven't been able to break anything with a small amount of tabs to mash, but i am still worried that maybe i am accessing the database in a poor way.

How can i prevent my SQLiteDatabase objects to cause a lock?

If i create a ContentProvider will that eliminate the possibility of database locking?

Do you have any suggestions for changes I could make for accessing data from an SQLiteDatabase?

I ended up taking the approach of using the Application class and storing 1 SQLiteOpenHelper and trying my best to keep it synchronized. This seems to be working great - i put all my 25 activities in the TabHost and mashed away on them with no errors.

I am calling ((SQLiteDbApplication)getApplication()).setDbHelper(new DBHelper(this, Constants.DB_NAME, null, Constants.DB_VERSION_CODE)); method(shown below) in every onCreate() in my activities

Any further suggestions to this approach or to the changes i made using this Application class?

Creating JPEG File In Internal Storage

Aug 14, 2012

I am writing a code for an android app in which I have to captures image and save it into internal storage of android. For this I have written the following code-

Code:

Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
String newPath = PATH+"/"+folderName+"/"+imageName+".jpg";
File file = new File( newPath );
file.mkdirs();

[Code]...

This code creates jpeg file but don't write the image into it.

Later I tried writing following code in onActivityResult-

Code:

protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 0, bos);
byte[] bitmapdata = bos.toByteArray();

[Code]...

But its still not working.

Android :: SQLite - Inserting String With New Lines Into Database From Csv File

Sep 9, 2010

I am trying to inject a long text entry into a SQLite database, in a TEXT field. This text has new lines in it (i.e. it spans multiple paragraphs). I can get the new lines to show up if I do the INSERT manually:

INSERT INTO "LOGENTRY" VALUES(5,40,'PLACE','line1
line2
line4
',1283990533315,'4A','TEXT','',NULL);

but if I have the equivalent text in a CSV file and attempt to .import it into the table, I get an error that it's expecting more columns than exist (as soon as the new line is encountered, the program assumes it's the end of the input and thus it's missing columns). Is this possible? Or is the only way to manually do each INSERT?

Android :: Read LARGE Sqlite File To Be Copied Into Emulator - Or Device From Assets Folder

I guess many people already read this article:

Using your own SQLite database in Android applications: http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/comment-page-2/#comment-12368

However it's keep bringing IOException at

CODE:.............

I'am trying to use a large DB file. It's as big as >8MB. I built it using sqlite3 in Mac OS X, inserted UTF-8 encoded strings (for I am using Korean), added android_meta table with ko_KR as locale, as instructed above.

However, When I debug, it keeps showing IOException at

CODE:..............

I suspect it's caused by trying to read a big file. If not, I have no clue why.
I tested the same code using much smaller text file, and it worked fine.

Can anyone help me out on this? I've searched many places, but no place gave me the clear answer, or good solution. Good meaning efficient or easy.

I will try use BufferedInput(Output)Stream, but if the simpler one cannot work, I don't think this will work either.

Can anyone explain the fundamental limits in file input/output in Android, and the right way around it, possibly?

Android :: Creating A Drawable From A SQLite Blob

The databases on both platforms report the exact same size for the same images. So I think, but can't guarantee, that the image data is getting into the database intact.But when I try to create a Drawable, the console prints out "DEBUG/skia(267):decoder->decode returned false".

Android : Creating App Database With Big Amount Of Data

Dec 23, 2009

The database of my application need to be filled with a lot of data, so during onCreate(), it's not only some create table sql instructions, there is a lot of inserts. The solution I chose is to store all this instructions in a sql file located in res/raw and which
is loaded with Resources.openRawResource(id).

It works well but I face to encoding issue, I have some accentuated caharacters in the sql file which appears bad in my application. This
my code to do this : Code...

The solution I found to avoid this is to load the sql instructions from a huge static final string instead of a file, and all accentuated characters appears well.

But Isn't there a more elegant way to load sql instructions than a big static final String attribute with all sql instructions?
