Why my Android App is being rejected

First: The initially upload response is “you are nearly there” to remove commented code and resubmit.
Second: After I removed all the commented codes than the upload response is “remove all your breakpoints”
Third: After I removed all the breakpoints in the project than the quick response less than an hour is " your app is rejected"

Don’t understand why this is happening… Please anybody can help.

There may be some reasons for getting your app rejected such as;
Crashing of App
Data Breach
Cloning of App
Design Quality Issues
Inappropriate App Content
Suspicious Products
Improper App Rating

You need to find out the appropriate reason for rejection and try to find the solution.
