添加appium依赖关系后出现Gradle构建错误

Question

I wish to use appium for automation testing (I'm using Android Studio for dev).
I added a gradle dependency for appium.
However, I am unable to run the app due to following warnings and non zero exit errors.

Warning:Dependency org.apache.httpcomponents:httpclient:4.4.1 is ignored for debug as it may be conflicting with the internal version provided by Android.
         In case of problem, please repackage it with jarjar to change the class packages

And error as:

> Error:Execution failed for task ':app:preDexDebug'.
> java.lang.IllegalArgumentException: Source
> D:\Learning\GDLearning\app\build\intermediates\pre-dexed\debug\websocket-client-9.2.11.v20150529-344b13c53e6f4871f43101e675dc9239cd9ab46b.jar
> and destination
> D:\Learning\GDLearning\app\build\intermediates\pre-dexed\debug\websocket-client-9.2.11.v20150529-344b13c53e6f4871f43101e675dc9239cd9ab46b.jar
> must be different

My build.gradle file is:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.example.gdlearning"
        minSdkVersion 11
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
                    'proguard-rules.pro'
        }
    }
    packagingOptions{
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
    }
}


dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile('com.google.api-client:google-api-client-android:1.20.0') {
        exclude group: 'org.apache.httpcomponents'
    }
    compile('com.google.apis:google-api-services-tasks:v1-rev41-1.20.0') {
        exclude group: 'org.apache.httpcomponents'
    }
    compile 'com.google.android.gms:play-services-ads:8.3.0'
    compile 'io.appium:java-client:3.2.0'
}

Any suggestion/ help would be great!
I explored on SO , tried a few things but it didnt worked.

You don't need to push appium dependencies to your app Build.gradle files. All you need to do is follow the instructions at official page.

http://appium.io/slate/en/master/?ruby#quick-start

Maybe you should:

1) Download Appium
2) Setting Evironment variables (ANDROID_HOME, JAVA_HOME, ..)
3) Play with the Appium 
4) Write some test code
