android-sdcard

I'm looking to create a sqlite database on the sd card (don't want to use up the user's internal storage). I'm familiar with the OpenHelper pattern: public DatabaseFoo(Context context) { OpenHelper openHelper = new OpenHelper(context); mDb = openHelper.getWritableDatabase(); } private static class OpenHelper extends SQLiteOpenHelper { public OpenHelper(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); } ... so if we want to create on the sd card, I think instead we have to use: public static SQLiteDatabase openOrCreateDatabase (String path, SQLiteDatabase.CursorFactory

I want to save a json file with all the application data (something similar to preference) but im not sure what is the limit size, because if the app cant use this file it will not function probably. is this information known beforehand and the OS reserve some space for your app or its based on the size available.

I am creating android application which contains DB that needs to be hidden(not able to access by the user)in the SD Card. Can anyone tell me how to do this? Any file stored on the SD card is accessible both by applications running on the phone, and by users who have mounted the SD card (both while it's in the phone and otherwise). You can change the file properties to make it 'hidden', but it will still be easily found. There is no way to make a file on a public partition like an SD Card 'secure' in the manner you describe - users will always be able to copy, delete, and potentially change
