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. :)

Answer 2

private boolean checkDataBase(){

    SQLiteDatabase checkDB = null;

    try{
        String myPath = DB_PATH + DB_NAME;
        checkDB = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY);

    }catch(SQLiteException e){

        //database does't exist yet.

    }

    if(checkDB != null){

        checkDB.close();

    }

    return checkDB != null ? true : false;
}

You can try it, hope this will be help you. And also check your dadabase version which support by Android 2.2. all the best.
