In my android studio project want to use existing java project code

I tried this way:

  1. Click File > New Module. Select Java Library and click Next.

  2. Filled the required fields and clicked Finish.

A new empty Java project library was created in my Android project.

I need to use existing(java project) code to my android studio project, how can I do that?

It is not possible to access with out gradle file,

you can use these steps if your Java project in eclipse

1.Right Click on project select export a new window appears

2.Select generate gradle build file then the select project click finish

It will create your project with gradle file,then you can easily import

File -> New -> Import module.....

    This is applicable for only android eclipse project.But what i asked above is, importing java project (java project is not having manifest file so it won't allow to import) in android studio. – Nageswara Rao.CH Aug 25 '15 at 08:22

You can import a java project if it is a Gradle build project. Otherwise android studio not allow to import other java projects.

File >> New >> Import Project and select the Gradle build java project

Importing a Gradle-based IntelliJ project

If you are already using Gradle with your IntelliJ project, you can open it in Android Studio using the following steps:

Click File > New > Import Project.
Select your IntelliJ project directory, and click OK. 
Your project will open in Android Studio.

On Android Studio 2.3.3

File -> New -> Import Project

Easiest way to do this is to choose the 'open an existing project' option, find your project, and then find the 'app' folder. Click on this to highlight it and then click 'Ok'. This will then import your complete project

I have had issues before with this so I normally just create a new project and just copy all the classes, drawables, etc from the old project into the new project.
