"Error: Attribute "size" already defined with incompatible format." when including library

[FranckRJ]

When i add the line compile 'com.takisoft.fix:preference-v7-colorpicker:26.1.0.2' in my build.gralde i got this error. When i click on it it show me these lines in a values.xml file :

<declare-styleable name="ColorPickerPaletteFlex"><attr format="reference" name="currentColor"/><attr format="reference" name="colors"/><attr format="boolean|reference" name="sortColors"/><attr format="reference" name="colorDescriptions"/><attr format="integer|reference" name="columns"/><attr format="enum|reference" name="size">
            <enum name="large" value="1"/>
            <enum name="small" value="2"/>
        </attr></declare-styleable>
    <declare-styleable name="ColorPickerPreference"><attr format="reference" name="currentColor"/><attr format="reference" name="colors"/><attr format="boolean|reference" name="sortColors"/><attr format="reference" name="colorDescriptions"/><attr format="integer|reference" name="columns"/><attr format="enum|reference" name="size">
            <enum name="large" value="1"/>
            <enum name="small" value="2"/>
        </attr></declare-styleable>

I use Android Studio 2.3.3.

Yes, this is a known "bug" due to the limitations of how Android handles the custom attributes. It's going to be fixed in the next release.

Thanks for the reply.

By the way, I think this error does not show up in Android Studio 3.0+. At least it seems to me that 2.3.3 makes the "size" attribute collide within the library, but Android Studio 3.0 does not have this problem. Probably the new gradle plugin is smarter.

Should be fixed since v26.1.0.3. All custom attributes must be prefixed with pref_.
