I published my first application on Google Play. Is a simple mortgage calculator [yes, one more;-)] with which you can perform your calculations for loans and mortgages.
The only goal has been to learn to program with B4A and be aware of all the steps required to publish the application.
Here I leave the link:
If you were possible, I would like you to do suggestions for improving the application.
Thank you very much to all who have helped me solve my doubts. Now the real fun begins!!
