Android xml package format does not recognize aapt properties

Question

I tried using the xml package format for Android with the example provided in Android Docs , but Android Studio keeps saying that

'drawable' or 'animation' must be defined ( See screenshot )

What can be done in this case to fix the error?

<!-- drawable\some_anim.xml--> <animated-vector xmlns:android="http://schemas.android.com/apk/res/android" xmlns:aapt="http://schemas.android.com/aapt"> <aapt:attr name="android:drawable"> <vector android:width="64dp" android:height="64dp" android:viewportHeight="600" android:viewportWidth="600"> <group android:name="rotationGroup" android:pivotX="300.0" android:pivotY="300.0" android:rotation="45.0"> <path android:name="v" android:fillColor="#000000" android:pathData="M300,70 l 0,-70 70,70 0,0 -70,70z"/> </group> </vector> </aapt:attr> <target android:name="rotationGroup"> <aapt:attr name="android:animation"> <objectAnimator android:duration="6000" android:propertyName="rotation" android:valueFrom="0" android:valueTo="360"/> </aapt:attr> </target> <target android:name="v"> <aapt:attr name="android:animation"> <set> <objectAnimator android:duration="3000" android:propertyName="pathData" android:valueFrom="M300,70 l 0,-70 70,70 0,0 -70,70z" android:valueTo="M300,70 l 0,-70 70,0 0,140 -70,0 z" android:valueType="pathType"/> </set> </aapt:attr> </target> 

Answer 1

You need to add extra things to some tags.

at

 <android vector add android:drawable=""> 

and in target tags

  <target add android:animation=""> 

and finally added a prefix to some tags in

  <aapt android:name="android:animation"> 

this is a whole copy of the code and paste it and then check:

 <animated-vector xmlns:android="http://schemas.android.com/apk/res/android" xmlns:aapt="http://schemas.android.com/tools" android:drawable="@color/divider"> <aapt:attr android:name="android:drawable"> <vector android:height="64dp" android:width="64dp" android:viewportHeight="600" android:viewportWidth="600" > <group android:name="rotationGroup" android:pivotX="300.0" android:pivotY="300.0" android:rotation="45.0" > <path android:name="v" android:fillColor="#000000" android:pathData="M300,70 l 0,-70 70,70 0,0 -70,70z" /> </group> </vector> </aapt:attr> <target android:name="rotationGroup" android:animation="@android:anim/slide_out_right"> <aapt:attr android:name="android:animation"> <objectAnimator android:duration="6000" android:propertyName="rotation" android:valueFrom="0" android:valueTo="360" /> </aapt:attr> </target> <target android:name="v" android:animation="@android:anim/cycle_interpolator"> <aapt:attr android:name="android:animation"> <set> <objectAnimator android:duration="3000" android:propertyName="pathData" android:valueFrom="M300,70 l 0,-70 70,70 0,0 -70,70z" android:valueTo="M300,70 l 0,-70 70,0 0,140 -70,0 z" android:valueType="pathType"/> </set> </aapt:attr> </target> 

Answer 2

I had to remove the android “cordova rm android platform” and re-add “cordova” with this command
