Can I download an SQLite db on /sdcard and access it from my Android app?

Question

I already found out that there is no way to bundle files in an .apk and have them on /sdcard, the best option so far being to download the large files upon first run. I came

Answer 1

Try this:

String dir = Environment.getExternalStorageDirectory().getPath()
File dbfile = new File(dir+"/mydb.sqlite"); 
SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(dbfile, null);
System.out.println("Its open? "  + db.isOpen());

Answer 2

Just an idea:

• you can put your database.db into the assets folder.

• if your database.db file is larger than 2Mb the system is unable to compress it, so you need other one options

• you can rename your database.db for example database.jit or database.mp3 - which are not compressed, than at the first run you can rename it to database.db

Answer 3

Sure you can. The docs are a little conflicting about this as they also say that no limitations are imposed. I think they should say that relative paths are to the above location and dbs there ARE private. Here is the code you want:

File dbfile = new File("/sdcard/mydb.sqlite" ); 
SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(dbfile, null);
System.out.println("Its open? "  + db.isOpen());

Answer 5

I share next code. Declare opcionesMenu Vector<String>

Vector < String > opcionesMenu = new Vector< String >();
// the database is SDCard. I saw  the code to Blackberry (net.rim)
String rutaDB = "/storage/extSdCard/Android/databases/Offshore.db";


    SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(rutaDB, null);

    Cursor cursor = db.rawQuery("SELECT Codigo, Nombre FROM Ruta ORDER BY Codigo, Nombre", null);

    if (cursor.moveToFirst())
    {
        do
        {
            opcionesMenu.add(cursor.getString(0) + " - " + cursor.getString(1));
        } while(cursor.moveToNext());
    }

    db.close();
