I have tried the following links
http://developer.android.com/intl/es/tools/building/multidex.html
UNEXPECTED TOP-LEVEL EXCEPTION: com.android.dex.DexException: Multiple dex files define
com.android.build.transform.api.TransformException
Java finished with non-zero exit value 2 - Android Gradle
com.android.build.transform.api.TransformException
My gradle build file is as below.
apply plugin: 'com.android.application'
android {
    compileSdkVersion 23
    buildToolsVersion '23.0.1'
    defaultConfig {
        applicationId "appId"

    }

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

    }
}

    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile files('libs/rt.jar')
    compile 'com.android.support:multidex:1.0.0'
}
My manifest is as below.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="packageName">
    <application
        android:name="android.support.multidex.MultiDexApplication"

        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

            </intent-filter>
        </activity>
    </application>
</manifest>
My activity file is as below.
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}
After all this, I still get the following error.
Error:Execution failed for task
