Description sperauer 2015-07-15 10:04:34 UTC
I added the v7 Support GridLayout Library to my project.

When I try to use the GridLayout class I get at runtime the following errors:
 * a classnotfoundexception when I instantiate the class in code
 * a layoutinflater error when I use the class in xml

I used the correct spelling and casing when I added the class in XML.
The project compiles fine when I instantiate the class in code

I missed the target framework settings as stated here, so this is resolved:

NOTE: Using this support library requires that your app have its Target Android Version (targetSdkVersion) set to Lollipop (5.0 - API Level 21) or higher, or you will have aapt related compile errors. You can still set the Target Framework which your app is compiled against as low as Android 4.0.3 (API Level 15).

sorry - this is not resolved.
I created a blank project added the support library and set the SDK settings as follows in visual studio:
 - Compile using android version: API level 19 (also tried with 21)
 - Minimum android to target: API level 19
 - Target android version: API level 21

the error is the same as stated in the original message

I cannot reproduce this behaviour, so I suspect it may have something to do with a corrupt download of the libraries.

Please try deleting all Android.Support* folders inside of C:\Users\YOUR-USER\AppData\Local\Xamarin

Then delete any obj/ and bin/ folders in your project, restart Visual studio, and try again!

Thanks

thanks, I did what you suggested. 

visual studio showed the following compile error:
 > The type or namespace name 'Support' does not exist in the namespace 'Android'

I also tried removing and adding the support libraries again, that didn't help.

I will close this issue as invalid as this is not reproducible for you and I unfortunately don't have time to look further into this.
