Error : Attribute already defined with incompatible format in "attrs.xml" in Xamarin.Android

I'm using Xamarin for developing my application. I've no problem with other platform such as UWP and iOs.

But when I try to build Android app I receive these errors:

Errors shown in Visual Studio 2017

All these errors refers to "attrs.xml" file shown belowe : 

    <?xml version="1.0" encoding="UTF-8"?>
<resources>
   <declare-styleable name="DrawableStates">
      <attr name="state_indeterminate" format="boolean" />
   </declare-styleable>
   <declare-styleable name="SfCheckBox">
      <attr name="isthreestate" format="boolean" />
      <attr name="cornerradius" format="float" />
      <attr name="checked" format="enum">
         <enum name="unchecked" value="0" />
         <enum name="indeterminate" value="1" />
         <enum name="checked" value="2" />
      </attr>
   </declare-styleable>
   <declare-styleable name="SfSegmentedControl">
      <!--        The selected index of SfSegmentCondrol-->
      <attr name="segmentSelectedIndex" format="integer" />
      <!--        The backcolor of SfSegmentCondrol-->
      <attr name="segmentBackColor" format="color" />
      <!--        The border color of SfSegmentCondrol-->
      <attr name="segmentBorderColor" format="color" />
      <!--        The border thickness of SfSegmentCondrol-->
      <attr name="segmentBorderThickness" format="string" />
      <!--        The color of SfSegmentCondrol-->
      <attr name="segmentColor" format="color" />
      <!--        The segment padding of SfSegmentCondrol-->
      <attr name="segmentedPadding" format="string" />
      <!--        The segment height of SfSegmentCondrol-->
      <attr name="segmentedHeight" format="string" />
      <!--        The segment width of SfSegmentCondrol-->
      <attr name="segmentedWidth" format="string" />
      <!--        The stroke thickness of SfSegmentCondrol-->
      <attr name="segmentStrokeThickness" format="string" />
      <!--        The corner radius of SfSegmentCondrol-->
      <attr name="segmentCornerRadius" format="string" />
      <!--        The position of SfSegmentCondrol-->
      <attr name="segmentPosition" format="enum">
         <enum name="top" value="0" />
         <enum name="bottom" value="1" />
         <enum name="fill" value="2" />
         <enum name="border" value="3" />
      </attr>
      <!--        The displaymode of SfSegmentCondrol-->
      <attr name="segmentDisplayMode" format="enum">
         <enum name="image" value="0" />
         <enum name="text" value="1" />
         <enum name="imagewithtext" value="2" />
      </attr>
   </declare-styleable>
</resources>

Is there any problem for my "attrs.xml" file? I already tried to clean and rebuild solutions. Remove and adding again every package but errors persists.

Thanks for your help.

Did you used the SfSegmentedControl from the Syncfusion like this link? https://help.syncfusion.com/xamarin-android/sfsegmentedcontrol/getting-started

Based on your error message, there are two issues.

Issue1 is related to segmentPosition segmentDisplayMode. I cannot find these attributes in SfSegmentedControl, you can refer to the following screenshot.If you want to define attributes in attrs.xml, SfSegmentedControl must have these attributes. enter image description here Solution: you could custom SfSegmentedControl to add these attributes.

Issue2 is related to SfCheckBox, the format of checked attribute is bool not enum like this screenshot.

enter image description here Solutions: change the format of checked
