Hello,​

Welcome to our Microsoft Q&A platform!

There is no "absolute path for a file existing in the asset folder". The content of your project's assets/ folder are packaged in the APK file. Use an AssetManager object to get an StreamReader on an asset as Jessie's answer.

For WebView, you can use the file Uri scheme in much the same way you would use a URL. The syntax for assets is file:///android_asset/... (note: three slashes) where the ellipsis is the path of the file from within the assets/ folder.

I think you have to use AssetManager

Hello,

Welcome to our Microsoft Q&A platform!

Yes, to access fille in Assets folder in android , you can use AssetManager to achieve this, just as alessandrocaliaro mentioned.

Suppose I put a google-services.json in folder Assets, then we can use the following code to access it:

    mTextView = FindViewById<TextView>(Resource.Id.mText);  

    string content;  
    AssetManager assets = this.Assets;  

    using (StreamReader sr = new StreamReader(assets.Open("google-services.json")))  
    {  
        content = sr.ReadToEnd();  
    }  

    mTextView.Text = content;  

For more detail , you can check: Reading Assets .
