Android SQLiteOpenHelper: Why onCreate() method is not called?

Question

I am trying to make my first Android app. I noticed that the SQLiteOpenHelper.onCreate() method is not called to create tables if the database not exists. Howev

Answer 1

I was having a similar problem with onCreate() not executing when the app was very first run, so my database never got created. This is NOT the same as when onCreate() is not executing because the database already existed, because the database did not yet exist. Specifically, my DataProvider onCreate() was not executing, so the OpenHelper never got called either.

I verified I had everything set up the way that everyone described in the previous answers, but nothing resolved my problem. Posting this answer in case anyone else forgets one small detail like I did.

What resolved the problem for me was adding a entry in AndroidManifest.xml for my Data Provider, nested inside the tags, along with all of my entries. The only attributes I needed were:

• android:name=".DataManagement.DbDataProvider"
• android:authorities="com.example.myApplicationName.DataManagement.DbDataProvider"
• android:exported="false"

(Make sure to change the values for the above attributes to match your project)

I cleaned, built, ran, and onCreate() methods for the data provider and open helper classes executed properly, and the database was created on first application launch!
