<h1>Short Answer:</h1>

See the detailed gradle output using <code>gradle assemble</code> and
note the files that are duplicate and exclude them using:

<pre><code>android {
 packagingOptions {
 exclude 'META-INF/notice.txt'
 }
}
</code></pre>

<h1>Long Answer:</h1>

Run the <code>assemble</code> gradle task from command line for detailed output:

<code>./gradlew assemble || gradle assemble
</code>

This automatically shows what to exclude:

<pre><code>studioWorkspace/CCDroid git:(master) ✗ ± ./gradlew assembleDebug

It's more than one error, you are right.

Under <code>apply plugin: 'android-library'</code>

add this ::
<code>
android {
 packagingOptions {
 exclude 'META-INF/ASL2.0'
 exclude 'META-INF/LICENSE'
 exclude 'META-INF/NOTICE'
 }
}
</code>

1st error is by file duplicates, 2nd is by LICENSE and NOTICE files.
It will work after

I had to play around a bit to find the right location for the packagingOptions. Solving the duplicate file problem for a conflict between jackson-core:2.2.2 and jackson-databind:2.2.2
Also the DSL seems to have changed recently 
So in the recent Android Studio 1.4.1 with buildTools 23 you have to put android.packaging options on the same level as compileOptions AND NOT inside any model { android { braces !

<pre><code>model { 
 android {
 compileSdkVersion = 21
 buildToolsVersion = "23.0.1"

 defaultConfig.with {
 applicationId = "com.android.sensorgraph"
 minSdkVersion.apiLevel = 21
 targetSdkVersion.apiLevel = 22
 }
 }

 android.packagingOptions {
 exclude 'META-INF/LICENSE'
 exclude 'META-INF/NOTICE'
 }
 compileOptions.with {
 sourceCompatibility = JavaVersion.VERSION_1_7
 targetCompatibility = JavaVersion.VERSION_1_7
 }
} 
</code></pre>

Android Studio. I'm getting this kind of error during application run.

<code>Error:Execution failed for task ':app:packageDebug'. Duplicate files copied in APK META-INF/notice.txt</code>

build.gradle

<pre><code>apply plugin: 'android'

How can I fix this error?

EDITED

These exclude options solved my problem:

<pre><code>packagingOptions {
