You are right.
I found my problem (which is not in the sample source code I posted first
(that's doesn't help !!!)
File f1 = Environment.getExternalStorageDirectory();
Log.v(TAG, f1.getAbsolutePath());
returns \sdcard under 2.1 and \mnt\sdcard unders 2.2
And I hardcoded "\mn
The following code just worked for me on the emulator (android 2.1):
File f1 = Environment.getExternalStorageDirectory();
Log.v(TAG, f1.getAbsolutePath());
String dbFilePath = f1.getAbsolutePath() + File.separator +
"extdir.db";
I made a mistake : the problem is under Android 2.1
The log cat under 2.1 Emulator is :
05-17 19:43:06.536: E/Database(245):
sqlite3_open_v2("/mnt/sdcard/chronogps.db", &handle, 6, NULL) failed
05-17 19:43:06.536: W/dalvikvm(245): threadid=15: thread exiting with
uncaught exception (group=0x400
Try in the 2.2 emulator and post the error log please.

As Mark says, if you're wanting to protect the data from access by

There is an open source SQLite-crypto package which I've used on

You could always encrypt the data in the database. See

It would be nice to be able to encrypt the enture DB, but that doesn't

What is Data Base Helper? There are a couple of them:
SQLiteOpenHelper; SQLiteQueryHelper and just the plain old database.
Your SQLiteOpenHelper can create stuff when you create your database,

Have you tried putting it on the sdcard? I have an app, used by

Hi Android-Berry:
Try:
insert into form values(null,11,22,33,44,55,66,77);
This would make sure that the _id gets automatically auto-incremented.
Hope it helps,
