Hi Evan, Thanks for your reply. The following is the "Error." message

(1) Error:duplicate files during packaging of APK /Users/CDLIM/AndroidStudioProjects/Stormy/app/build/outputs/apk/app-debug-unaligned.apk

(2) Error:Execution failed for task ':app:packageDebug'.

Duplicate files copied in APK LICENSE.txt File 1: /Users/CDLIM/.gradle/caches/modules-2/files-2.1/junit/junit/4.11/4e031bb61df09069aeb2bffb4019e7a5034a4ee0/junit-4.11.jar File 2: /Users/CDLIM/.gradle/caches/modules-2/files-2.1/org.hamcrest/hamcrest-core/1.3/42a25dc3219429f0e5d060061f71acb49bf010a0/hamcrest-core-1.3.jar

I was following Ben Jakuben's "Build an App Weather" course. I am only at the first few videos and *I have not alter anything in Android Studio except in Build.gradle(module app) *

the following are the codes in build.gradle(module app) 

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "23.0.0 rc2"

    defaultConfig {
        applicationId "com.example.cdlim.stormy"
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.squareup.okhttp:mockwebserver:2.7.0'
}

Thanks again for looking into it and for your time.

Regards CD Lim

Hi CD,

Try adding the following to your build.gradle after your closing bracket for buildTypes:

packagingOptions {
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/DEPENDENCIES'
}

At this point I'd recommend downloading the project files (which we know should work) and running that; if it works, compare the code in the working project to your own code to see what's different.
