Android Database will not delete but does on IOS

I am using the same code on both ios & android ... it works perfectly on ios but android wont delete the database .... we count the the lines in the database and send the data to our server ... once the number is zero it erases the database... 1) the database is not being erased so we are sending alot of duplicate data and an enormous amount the next time user runs our program... as a side note can someone send me a tutorial of how to view the android database ... a really basic one for people new to android. using adb i was able to locate the databasefile, but not view it or copy the file out of adb to my desktop
