How to import class from another module in android studio?
提问by Palak
I created two modules in single android project, named it x and y.
我在单个 android 项目中创建了两个模块，将其命名为 x 和 y。
- Module x has a class Egg (Package: com.example.x)
- Module y has a class Foo (Package: com.example.y)
- 模块 x 有一个类 Egg（包：com.example.x）
- 模块 y 有一个 Foo 类（包：com.example.y）
Now I want to import class Foo in the class Egg, for which I wrote the statement mentioned below in class Egg
现在我想在类Egg中导入类Foo，为此我在类Egg中写了下面提到的语句
Import com.example.y.Foo;
Now, Foo is not recognized by android.
现在，Android 无法识别 Foo。
Questions,
问题，
Is it possible to import Class from a different module using just import statement?
Do I need to create library of Module y and then import created library into module x?
是否可以仅使用 import 语句从不同的模块导入 Class？
我是否需要创建模块 y 的库，然后将创建的库导入模块 x？
Or may the solution is something else.
或者可能解决方案是别的。

Make sure of the following:
请确保以下几点：
In settings.gradle, you should have: include ':x', ':y'.
在settings.gradle，你应该有：include ':x', ':y'。
In x/build.gradle, you should add y as a dependency:
在 x/build.gradle 中，您应该添加 y 作为依赖项：
dependencies {
compile project(':y')
// other dependencies
}

now when create new module,settings.gradle add automatically this module.after that u should add this line:
现在当创建新模块时，settings.gradle 会自动添加这个模块。之后你应该添加这一行：
dependencies {
implementation(
...,
..,
project(":y")
)
}

Combining and correcting two previous answers the best solution is to add this single line to x/build.gradle -> dependencies
结合并更正之前的两个答案，最好的解决方案是将这一行添加到 x/build.gradle -> dependencies
implementation project(':y')
compile project()- is deprecated and won't work anymore
compile project()- 已弃用，不再工作
If you want to implement just a single module there is no need to use implementation(..., .., project(":y")structure.
如果您只想实现单个模块，则无需使用implementation(..., .., project(":y")结构。
