how to call data from activity to another without the button only display the data inside the database<>
This question already has an answer here:
Uninstall and reinstall your app
This is because, once your app is deployed in the emulator or testing device, and after that if you make any changes to the structure of the database, it wont be reflected and you get an error. when you reinstall it, the database is created as a new one and thus no error..!!!
@DerGolem mentioned a valuable comment above
If you modified the database since it's original creation, then be sure you have an onUpgrade() method. And that you set the DATABASE_VERSION constant to a higher number.
Thanks @DerGolem for pointing out that as I was really unaware about that fact..
