如何将库导入 build.gradle

Question

I'm trying to resolve some problem and I found old solution: Gradle build null console object

the problem is, the solution includes importing something in the gradle.

How to import for eg: import javax.swing.JOptionPanel ?

I have never imported anything in the build.gradle and I can't find examples with it.

Swing (and JavaFX) are used for Java Desktop applications.

So you can't use Java Swing on Android because Java Swing is not supported on Android. Android System has its own UI API framework already inbuilt and doesn't use Swing Library at all.

That said to import a Library into gradle you can follow these steps.

1. In Android View, open build.gradle file (module app)

2. Find the dependencies section towards the bottom of the file: you will note there are other libraries already imported for you.

3. Add the library you need by following this format

implementation group: 'com.example.android', name: 'app-magic', version: '12.3'

4. You can use Google to find the Library group, name and version:
