Android Question Can not init sqlite database

[Ioannis Poulianitis]

Hello to all. I am just learning how to use vb4android. I wrote a litle app to open a database of another app in it's data folder in internal storage.

My phone is rooted. But always getting error.

I have access to data folder. I can read databases size as i can verify that exists as file.

Can you take a look???

Thank you.

It is probably a permission error. You process will not run as a super user even if the device is rooted. You can use a solution such as this one to create a super user process: Running shell commands as SuperUser
This will allow you to copy the database to a different location.
