How to import javax.smartcard library in android studio? - java

I am currently using javax.smartcardio in a spring project using eclipse. I added the library in eclipse by going to Build Path > Configure Build Path > Module Dependencies and then selecting the javax.smartcardio from the list then Apply and Close.
Now I am working on an android project which is using the same hardware that I used in spring project. As of my current knowledge, I know that javax.smartcardio is present already in Java SDK. Now I need to import the same module in Android Studio to use in my android project but don't know from where to add the javax.smartcardio library into my android studio project.
Looking forward to hearing soon. Thanks

Include existing source from Eclipse into Android Studio

I am trying to setup a project in Android Studio which includes several source files from an Eclipse project.
The Eclipse project has the following structure:
Library Project
It has a reference to several folders with java classes in them (included by link source)
Now I'd like to have these resources in my project/module in Android Studio too, but I can't find any possibility to achieve this other than copying them directly.
I'd like to avoid this because these files are part of a self written Java framework which is used in combination with GWT too. So copying these files instead of linking them means all changes have to be done twice.
Is it possible to include these sources similar to link source from Eclipse or is there another solution?
You could build your Eclipse project and reference it as a library in Android studio project. Then you would be able to access/use the required classes in the Android studio project.

How to add Gradle to an existing project in Android Studio?

I have an existing project in Android Studio that I originally imported from Eclipse.
I haven't been using any specific build system to build my project other than the one provided by default with the Android Studio IDE (though the project was originally created with Eclipse.
I haven't been able to find a good tutorial of the steps. What's the recommended approach to add Gradle to this project?
Any help would be greatly appreciated.
Thanks!
I would recommend creating a new project in android studio as the folder structure used by gradle is different than the one used by eclipse. Then copy the files into their matching folder.
Here is a detailed description about the folder structure: https://developer.android.com/tools/projects/index.html

How to add exisiting java source project to Android Studio

I have an existing git repository of pure Java code that I would like to add to my Android project.
I don't want to change any of the existing files. I want to keep my existing package names to simplify the maintenance of my legacy code.
In Eclipse, you can simply add the root of the existing project to your Java Build Path.

How to import eclipse project from git to Android Studio?
My solution to this was to Export my Java project to a JAR.
And then, I added the JAR to the Android Studio project.
File > Project Structure leads to this window:
That way, I could use my files untouched as such.
I am not so happy with this solution because it breaks my revision control system.

What steps do I need to take to convert my Eclipse Android project into a Gradle project?

I was wondering if it is an easy or worthwhile effort to convert my current Android project in Eclipse into a Gradle Project. Is there a generic build.gradle file I could start with that has common build tasks for Android? Would I just need to download a Gradle plugin for Eclipse or would I need to download Gradle by itself? Are there available tasks to run the project on a connected device like the Eclipse Android plugin can already do? Any input is appreciated.
Any project with build.gradle is Gradle project.
You can add build.gradle via File -> Export -> Android / Generate Gradle build file
or use build.gradle template for classic Android project check
gh.c/N/n-1/b/m/o.n.e.e.g/docs/android/build.gradle.
see http://www.nodeclipse.org/projects/gradle/ for info about Gradle support in Eclipse
Are there available tasks to run the project on a connected device like the Eclipse Android plugin can already do?
there is android-command plugin referenced in template.
Be aware that all Android-Gradle related is currently beta, including Android Studio.
I recommend to read docs well
http://tools.android.com/tech-docs/new-build-system
http://www.gradle.org/
I don't know of any standalone Gradle tools, but if you install Android Studios, and import your eclipse project, it elegantly converts it to Gradle for you. This is what I did.
If your target IDE is android studio.I use android studio 0.8.9 and from experience when I am moving my eclipse projects I simply go over to android studio,under the file menu and import the eclipse project.Android studio uses the latest version of the gradle plugin to do the job of proper conversion.Note:Make sure your gradle plugin option is turned on to work online.
