How to compile JAR with library to apk

Question

I get jar file with library from NetBeans and i cant convert it to apk. Converter ask JAD and JAR files.

I have one main jar and two more in lib folder.

Answer 1

You can't convert .jar file to .apk! inside a jar file we have .class files but inside the .apk we have .dex files which .dex files can convert to .class and after that .java. so you can see a jar file is one step behind the .apk file

Answer 2

将项目（模块）设置从库更改为应用程序。
