Why does getWritableDatabase crashes on some devices? (sqlite3_open_v2 ... Failed)

My application uses a database and works pretty well on all Android devices.

Recently some users pointed that it crashes on HTC Tattoo. I decided to give a try and got one in loan.

So, the error come when I call: this.getWritableDatabase();

09-27 18:26:22.292: ERROR/Database(1537): sqlite3_open_v2("/data/data/com.xxx.xxx/databases/radars.db", &handle, 6, NULL) failed
09-27 18:26:22.292: WARN/System.err(1537): android.database.sqlite.SQLiteException: unable to open database file

A开发者_高级运维nd I have checked, the Database is in the device:

I really cannot understand what happens....

Thank a lot for your help!

EDIT:

As noticed by LAS_VEGAS

# sqlite3 /data/data/com.xxx.xxx/databases/radars.db 

Gives this result:

sqlite3: not found 

Seem that the HTC Tattoo has serious SQL issues:

adb shell

# cd /system/xbin

# ls | grep sqlite3

//Nothing//

This is weird. I think this could happen when you try to access database file from multiple threads simultaneously. Could it be the case?

Also for testing purposes did you try getReadableDatabase(), maybe it gives a clue...

EDIT:
Can you access from remote shell?:

EDIT2:
So it seems that HTC tattoo has no sqlite3.
