conver from Java files to Apk

I first tried using a lot of tutorials and the questions that I read on this site, so I tried to make the application a little change. I got a decomplie using apktool Then I got the jar file with dex2jar and got the java files using jdx Now I edited the java file I wanted to edit and the changes made Now I have a folder that has two other folders named sources and resources, including class and Java files. Now, how can I turn this harrow into a apk so I can install it? see the picture below i have these files

i need to know how to use this files and combine them together to build an apk
