Element must be declared error for tag shape

I'm using Android Studio I/O(Preview) 0.3.2

I'm using this example to define background gradient in my app. I get Element must be declared error.

I've checked and I'm not find any solutions. Can anyone help me how can I declare that tag in the xml

This problem was caused by my xml file. My gradient XML file was in the values folder, I solved this problem by moving gradient file to drawable folder

You could just right click

> res

and hit

> New

, to create a

> Android Resource File

, and choose

> Resource Type

to be

> Drawable

, and change whatever the default

> root element

to

> shape

Yeah it's kinda buggy in Android Studio to create a new XML file other than layout and values lol.

hope it can help you!!

I had the same problem with Android Studio , I created a directory "anim" under "res" then copied the xml file to that one then the error gone.

You need to use selector inside <set/> tags like that;

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_enabled="true" android:state_pressed="true">
            <objectAnimator
                android:duration="@android:integer/config_shortAnimTime"
                android:propertyName="translationZ"
                android:valueTo="15dp"
                android:valueType="floatType" />
        </item>
        <item>
            <objectAnimator
                android:duration="@android:integer/config_shortAnimTime"
                android:propertyName="translationZ"
                android:valueTo="5dp"
                android:valueType="floatType" />
        </item>
    </selector>
</set>

Had a similar problem with the selector tag used to create a state list animator.

My animation was in the anim resource folder. Had to move it to the animator folder.

Looking at that example, I think if you add the xmlns:android attribute (inside the shape tag, as in the example that you are following), it will work:

xmlns:android="http://schemas.android.com/apk/res/android"

I suspect that shape is declared there.
