I also have a problem with sqlite3_open_v2.

but after searching for this problem, I found a link, and I changed my code to match that link, and the modified code looks like this:

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

Hope this also helps solve your problem. :)

 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, hope this helps you. Also check out the dadabase version supported by Android 2.2. all the best.
