Android Studio XML does not recognize objectAnimator

Question

I have been trying to animate a transition between two fragments. I had originally placed them a property animations in xml (and that didn't really work), then changed it to objectAnimator. For some reason Android Studio is not recognizing the objectAnimator tag.

here is my AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.example.nick.randomapplication" >      <application         android:allowBackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/Theme.Base.AppCompat.Light" >         <activity             android:name=".MainActivity"             android:label="@string/app_name" >             <intent-filter>                 <action android:name="android.intent.action.MAIN" />                     <category android:name="android.intent.category.LAUNCHER" />             </intent-filter>         </activity>     </application>  </manifest> 

my build.Gradle:

apply plugin: 'com.android.application'  android {     compileSdkVersion 20     buildToolsVersion "20.0.0"      defaultConfig {         applicationId "com.example.nick.randomapplication"         minSdkVersion 19         targetSdkVersion 20         versionCode 1         versionName "1.0"     }     buildTypes {         release {             runProguard false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     } }  dependencies {     compile fileTree(dir: 'libs', include: ['*.jar'])     compile "com.android.support:appcompat-v7:20.0.+" } 

and the xml file:

<?xml version="1.0" encoding="utf-8"?> <objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"> </objectAnimator> 

Thank you for taking your time to look at this. I'm not sure what to do anymore.

I think you have placed the xml file in a wrong folder.

valueAnimator objectAnimator and animatorSet resources should be in the folder res/animator, not in res/anim.
