Android FragmentTransaction Custom Animation (Unknown Animator Name: Translate)

I'm trying to get a custom animation to work with my fragment.

I've followed the online tutorials but I've been getting the below error:

java.lang.RuntimeException: Unknown animator name: translate

The XML for the animation is below:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
    android:fromXDelta="100%"
    android:toXDelta="0"
    android:duration="300" />
</set>

The Java file is shown below:

public void goCategory(View v) {		
	FragmentTransaction ft = fm.beginTransaction();		
	ft.setCustomAnimations(R.animator.anim_in_left, R.animator.anim_out_left);				
	ft.show(fragment);
	ft.commit();
}

I'm having trouble understanding the solutions in the other threads. If someone could dumb it down for me, I'd really appreciate it.

Probably you are mixing two apis. There are two cases:

• If targeting below 3.0 or using support v4 fragments: You have to use the old animations api, that is, the one you are using (they go into anim/, and are R.anim.thing)

• If you are targeting above 3.0 and using native fragments: You have to use the new animation apis, that is, ObjectAnimators (they go into animator/ and are R.animator.thing).

It will not work, you should use object animator

animator/slide_in_left.xml

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

    <objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="500"
        android:propertyName="x"
        android:valueFrom="1000"
        android:valueTo="0"
        android:valueType="floatType" />

</set>

animator/slide_out_right.xml

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

    <objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="500"
        android:propertyName="x"
        android:valueFrom="0"
        android:valueTo="-1000"
        android:valueType="floatType" />

</set>

Class Subcategory

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
    			Bundle savedInstanceState) {
    		// TODO Auto-generated method stub
    		// return super.onCreateView(inflater, container, savedInstanceState);
    
    		View view = (ViewGroup) inflater.inflate(R.layout.product_frame, null);
    		getFragmentManager().beginTransaction()
    				.replace(R.id.sub_header, new Sub_Header()).commit();
    		getFragmentManager()
    				.beginTransaction()
    				.setCustomAnimations(R.animator.slide_in_left,
    						R.animator.slide_out_right, 0, 0)
    				.replace(R.id.product_frame, new Sub_Catagory_Grid()).commit();
     
    		view.getWidth();
    		return view;
    
    	}

As @minivac replied you are mixing two APIs. Please, take a look to Display Card Flip Animations example from Android training guides to get a further understanding about how to add custom animations to fragment transactions. It solves exactly your issue.
