The parseInt error thing has resolved last time so thanks a lot. Now, this time, the problem is with running the app. Though I find no errors in the code, I can't run the program and it force close saying "Unfortunately, has stopped"
Is there something I did wrong or is there something missing from my system? I'm using (again) the 1.1.0 version of AndroidStudio. I'll be providing my MainActivity, Contact class and DBHandler class to help you guys out and please do try to run it. I hope you could help me resolve this issue. Thank you.
