            android:entries="@array/sizes"
            />


    </LinearLayout>

</android.support.constraint.ConstraintLayout>

But when I try to populate the Spinner list by changing the contents of the strings.xml file, I get the error "android resource linking failed"

strings.xml

<resources>
    <string-array name="sizes">
        <item>5</item>
        <item>10</item>
        <item>15</item>
    </string-array>
</resources>

And it throws me into the AndroidManifest.xml file

AndroidManifest.xml

Build

When I try to create a list, through the "ListView" widget, it throws the same error. How to fix this problem?

Answer 1

In strings.xml, there must also be all those parameters that are accessed by the resource in other xml files of the interface. In this case AndroidManifest.xml
