I have just found the solution.

I had to take the context with

Solution 2:

Try this

(YourActivityName)Forms.Context;

for example:

var activity = (YourActivityName)Forms.Context;

If you are in Activity.

You are casting Application context.

var context = Android.App.Application.Context; 

Replace it with below

var context = android.content.Context; 

If you are working in Service then you can ask for permission from where you are calling your service.
