如何从另一个模块调用Java类

Question

I have a project with the structure

android/src/com.xy/A.java

core/src/com.xy/B.java

I want to call a method from A.java in B. java. I have searched the internet for solutions i have added the lines

implementation project(path: ':core', configuration: 'default')

in android's build.gradle and

implementation project(path: ':android', configuration: 'default')

in core's build.gradle file.

It builds with success but i cannot call the class from B. java

Answer 1

Import the statement

import android.src.com.x.y.A.*;

Then make an object of A.java as follows:

A a = new A();

Then use it's methods in class B wherever you want.

a.pqr()
