SQLite database creation fails, documentation is unclear

When I add this code to my Android 2.1 Java app, it fails:

db=SQLiteDatabase.openOrCreateDatabase("Locations", null);

Do I need a special permission to create a database, or can 开发者_如何学编程anybody provide a suggestion how to find out what goes wrong?

Here is the LogCat output:

Any app can make a SQLiteDatabase without any special permissions.

I'm a little thrown by your code snippet because in my documents/SDK openOrCreateDatabase (on Context) takes three parameters: name, operating mode and factory. https://developer.android.com/reference/android/content/Context.html

It will be very revealing to see the output of your 'adb logcat'. Either run the adb application from a console, or bring up the LogCat window in Eclipse (it might help to switch to the DDMS Perspective). Run the app, get the failure and paste the later lines here.
