Problem

Intellisense could not pick the attributes we type although those attributes are existing in android SDK and shows this Attribute is not declared.

Solution

I got this problem yesterday in Visual Studio 2015 and started searching about this, ultimately I found that these two files are missing in XML schema folder in Visual Studio, so download these files links given below,

1. https://github.com/atsushieno/monodroid-schema-gen/blob/master/android-layout-xml.xsd
2. https://github.com/atsushieno/monodroid-schema-gen/blob/master/schemas.android.com.apk.res.android.xsd

Just download and move files manually to C:\Program Files (x86)\Microsoft Visual Studio 14.0\Xml\Schemas or simply just add these schemas within Visual Studio. This error will be gone, I resolved this issue with this procedure.
