I am trying to work on new app on android studio, i used to work on e

 UNEXPECTED TOP-LEVEL EXCEPTION:
  com.android.dex.DexIndexOverflowException: method ID not in [0,

What could this error be?

i have moved some jar files to my eclipse. and my build.gradle is like this

   apply plugin: 'com.android.application'
     android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
    applicationId "com.netvariant.heinz"
    minSdkVersion 14
    targetSdkVersion 21
    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:design:23.1.1'
compile 'com.google.android.gms:play-services:8.4.0'}

I think your dex file is reached to its maximum method count. Try to use

multiDexEnabled true

in your deafault config or try to minmize your playservices from your dependencies. Use only required packages. Try changing your version or exclude unwanted packages
