如何导入的javax.swing在Android Studio中

I am trying to build my android project. I could not understand even if the **rt.jar** which contains classes of,

 **javax.sound.*.**
 **java.awt.*.**
 **java.awt.** 

is already there in the jdk1.7/jar folder and also it can be loaded seen under IDE librarie/java but it gives me the error of saying the library classes not found. When i imported the library to the project and build it it says,

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:packageAllDebugClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: javax/xml/XMLConstants.class

duplication error of classes. How come this happen?

Any help will be really appreciated to overcome this issue.

Please find the build.gradle file here,

apply plugin: 'com.android.application'

android {

    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "info.androidhive.sleepApp"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        // Enabling multidex support.
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.android.support:recyclerview-v7:22.2.0+'
}

This is the gradle error:
