If you check the Messages tab there should be a more descriptive message explaining why it failed.

You might be experiencing the same problem as I am since the new androids release. I used the SDK manager to download the latest stable sdk (Which was 25 at the time) and set that as my compile and target sdk inside the build.gradle (Module:App) file. Now after you change that the palette and recycler view dependencies will be throwing an error, This is because their 'Major' number needs to be the same as the compileSdkVersion, and the other 2 version numbers need to not exceed the latest version. Sync the project with your compile version and then 2 0's afterwards (25.0.0 for example) and the IDE will recommend the correct version. If you do not download the newest sdk from the sdk manager you will get an error asking you to install these versions from a repo. THEN you need to visit https://github.com/JakeWharton/butterknife and find out the correct import lines for the butterknife api that needs to be in your gradle files, and last but not least, you need to change the annotation of @Bind to @BindView for every butterknife binding, also change the imports within those java classes to import butterknife.bindview

Below are the examples of all of this

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.jimulabs.googlemusicmock"
        minSdkVersion 19
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    lintOptions {
        disable 'InvalidPackage'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

    //Dependencies that needed to be changed
    compile 'com.android.support:recyclerview-v7:25.1.0'
    compile 'com.jakewharton:butterknife:8.4.0'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'
    compile 'com.android.support:palette-v7:25.1.0'

    compile 'com.jimulabs.mirrorsandbox:mirror-sandbox:0.2.1'

}

The GitHub documentation also told me to add a line to the Project gradle file as well

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

        //Line that was required to be added by butterknife
        classpath 'com.jakewharton:butterknife-gradle-plugin:8.4.0'

    }
}

allprojects {
    repositories {
        jcenter()
    }
}

Your version numbers WILL be different, so if this doesn't work for you then you will need to read the error messages provided by the IDE to find out what is wrong

Clean and Rebuild the project.....if it's failing for the SDK version lower the min SDK in the build.gradle Module from 24 to 23

To anyone having trouble using a physical device like me, I have android sdk 16 on my cell. (my emulator never works)

As of Oct 2016 update your gradle project file classpath to 'com.android.tools.build:gradle:2.2.1' then sync

then go to gradle module:app and input in minSdkVersion 15 then sync

it might say building for a long time, if it does this too long just restart your computer and open Android Studio again and everything should work fine.

15 is the minimum version supported by default as of Oct 2016....but now the app runs fine on my mobile device.

Hope that helps the emulator-less like me haha.
