Android – Where to get database error information in Android SQLite (e.g. failed insert due to violation of not null)

An update mentioned in the comments below:

You don't need to be on the DDMS perspective anymore, just open the File Explorer from Eclipse Window > Show View > Other... It seems the app doesn't need to be running even, I can browse around in different apps file contents. I'm running ADB version 1.0.29

Or, you can try the old approach:

Open the DDMS perspective on your Eclipse IDE

(Window > Open Perspective > Other > DDMS)

and the most important:

YOUR APPLICATION MUST BE RUNNING SO YOU CAN SEE THE HIERARCHY OF FOLDERS AND FILES.

Then in the File Explorer Tab you will follow the path :

data > data > your-package-name > databases > your-database-file.

Then select the file, click on the disket icon in the right corner of the screen to download the .db file. If you want to upload a database file to the emulator you can click on the phone icon(beside disket icon) and choose the file to upload.

If you want to see the content of the .db file, I advise you to use SQLite Database Browser, which you can download here.

PS: If you want to see the database from a real device, you must root your phone.

The problem, as it turns out, is that the PDO SQLite driver requires that if you are going to do a write operation (INSERT,UPDATE,DELETE,DROP, etc), then the folder the database resides in must have write permissions, as well as the actual database file.

I found this information in a comment at the very bottom of the PDO SQLite driver manual page.
