Answer 1

I am also having same problem sqlite3_open_v2 failed

but After searching on this problem I found this link and I modified my code according to this link and the modified code is look like this:

public boolean databaseExist()
{
    File dbFile = new File(DB_PATH + DB_NAME);
    return dbFile.exists();
}

hope this also helps in solve your problem. 🙂
