There is no reference site for working with Cordova plugin in Android Studio,
I haven't had time to link plugins, so this is an Eclipse settings memo that I was told a little.

By the way, the download destination of SDK is here↓

The AAR package import procedure in Eclipse is roughly divided into the following procedures.
1. Extraction (decompression) of AAR package
2. Creating a new library project
3. Reflect the extracted package file in the created library project
4. Add the created library project to the target project
5. Add code that focuses on the view object of the target application screen (sample code)

[1. Deployment (decompression) of AAR package]

・The extension of the provided AAR package (UIEMultiAccess-densoRelease.aar)
Change to zip and unzip to any folder
・UIEMultiAccess-densoRelease
−aidl
−assets
−jni
−libs
−AndroidManifest.xml
−classes.jar
−R.txt
The above will be expanded

[2. Creating a library project]

1. Select "file>New>Android Application Project"
2. Input various setting items in the "New Android Application" wizard
The "New Android Application" window appears, and the Android project wizard
Will start
2-1: Enter each item on the "Creates a new Android Application" form and press "next>"
・Appication Name:UIEMultiAccess
・Project Name :UIEMultiAccess
・Package Name :uie.multiaccess
・Minimum Required SDK:API 18Android 4.3(Jelly Bean)
・Target SDK :API 19Android 4.4(KitKat)
・Compile With :API 19Android 4.4(Jelly Bean)
・Theme:none
* SDK version above is minSdkVersion and targetSdkVersion of AndroidManifest.xml extracted from AAR package.
Please set according to
2-2: Confirm the following check items on the “Configure Project” form and click “Finish” to complete.
・Uncheck "Create custom launcher icon"
・Uncheck "Create activity"
・Check "Mark this project as a library"
* Wizard items and screen transitions may differ depending on the version of eclipse (confirmed by Helios)

[3. Reflect the unzipped package file in the created library project]

1. Copy the contents of the unzipped AAR package below to the home directory of workspace of the library project.
−AndroidManifest.xml
−assets
-Res
−libs
−classes.jar
* Copy to the same libs/ as other jar files

[4. Add the created library project to the target project]

1. Right click the application project and press "Properties"
2. Press the "Android" tab of the project settings window
3. Press the "Add" button to the right of the "Library" item
4. "UIEMultiAccess" created earlier will be displayed in the project list of the library. Select it and complete the setting.
5. Confirm that the library project has been added
− Open “Android Dependencies” directly under the application project.
→It is OK if the "uiemultiaccess.jar" added earlier is present.
*If you can't refer to it, click Refresh or "Project>Clean..." of the project to refresh the project and check again.

[5. Code added to focus on the view object of the target application screen (sample code)]

See sample Activity and layout that focuses on a button
