Answer 1

there might be a conflict with your dependencies

try removing

compile project(':android-support-v4')

Answer 2

I had the same error and FULLY enabling multidex worked for me. here is what I did in gradle and manifest files

android {
compileSdkVersion 21
buildToolsVersion "21.1.0"

defaultConfig {
    ...
    minSdkVersion 14
    targetSdkVersion 21
    ...

    // Enabling multidex support.
    multiDexEnabled true
}
...
}

dependencies {
compile 'com.android.support:multidex:1.0.0'
}

also in my manifest file, I have add the MultiDexApplication class from the multidex support library to the application element like this

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.example.android.multidex.myapplication">
   <application
       ...
       android:name="android.support.multidex.MultiDexApplication">
       ...
   </application>
</manifest>
