Reason

My Xamarin project uses multiple languages and their translations are stored in Resource/.resx files. When I build the project in VS 2015 the android project not built successfully and it gave me an error…

Error

Multiple substitutions specified in non-positional format;
did you mean to add the formatted=”false” attribute?
Mobility_App.Droid F:\Mobility_App.Droid\Resources\Values-fr\AppResources.xml

Image 1 : Error

Reason

I search the error and I found the issue occurred because some <string> tags consists of percentage(%) symbol.

Solution

To fix this error we have to add a attribute “Formatted” to <string> tags which are consists of ‘%’ symbols. and Set “Formatted” attribute’s value to “false”.

Image 3 : add <string formatted=”false”>

Now the issue has fixed and to ensure, then rebuild the project and you can see the solution is success.
