Problem with displaying data on android

Dear all,
I have a problem with displaying a long list of data from database to the android. When the data in the database has three rows, the device (phone) displays them but when I add new rows to database, the device doesn’t display anything.

what should I do so that all data from the database to be rendered on the phone screen?

Hi,
Please add some code.
What happens If you hardcode 4 rows and try display.
Does database return all 4 rows without error?
