how can I extract a PDF stored in my app resources.raw directory to the working device

Issue

I have a pdf Form stored in my xamarin android app resources. I want that the app user can extract the Form from the resources and fill it.

I found some samples in nativ android, but I cannot adapt it to Xamarin. I need to get the resource file to an input stream, but do not succeed.

Solution

First, when you have a file in raw folder of the Resource folder of Android project, you could open a data stream for reading a raw resource.

I add a file named file1 in raw older for reference.

 var stream = Resources.OpenRawResource(Resource.Raw.file1);

If you want to read the string from the stream, you could use the code below.

BufferedReader reader = new BufferedReader(new InputStreamReader(stream));
        string line=reader.ReadLine();

And then, if you want to get this in Xamarin.Forms, you could use DependencyService. For more details, check the link below. https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/dependency-service/introduction
