Answer 1

In Xamarin.Android project, Assets are read using an AssetManager. An instance of the AssetManager is available by accessing the Assets property on an Android.Content.Context, such as an Activity.

For example:

string content;
AssetManager assets = this.Assets;
using (StreamReader sr = new StreamReader (assets.Open ("zimbabwe.shp")))
{
    content = sr.ReadToEnd ();
}

And in Xamarin.Forms project,you could also add any file into the Assets folder in the Android project and mark the Build Action as AndroidAsset to use it with OpenAppPackageFileAsync.

using (var stream = await FileSystem.OpenAppPackageFileAsync(templateFileName))
{
  using (var reader = new StreamReader(stream))
  {
    var fileContents = await reader.ReadToEndAsync();
  }
}
