how to pass android activity context from typescript file to Java file in nativescript

Question

I have been doing InAppBrowser(Webview to load an url) in Nativescript. From nativescript, I want to use InAppbrowser native android webview code for some reason.
So I got one sample link to look out:

https://www.codeday.top/2017/10/23/52017.html

With the help of reference I tried to pass activity context from nativescript file to typescript.

Error : But I'm getting cannot convert object to context error in Command prompt.

Below I have posted the code what I have been tried so far:

app.component.ts:

var activity:any = android.app.Activity;

export class AppComponent {

    onTap(args: EventData) {     

        org.example.MyToast.showToast(activity);  --> Here I'm passing object.So it doesn't take activity context reference. That's why I'm getting error.
    }   

}

MyToast.java:

public class MyToast {

    public static void showToast(Context context) {  

        final Dialog openDialog = new Dialog(context);
   }
  }

I don't know how to pass activity context reference in nativescript to typescript file. Could anyone help me out.

instead of this var activity:any = android.app.Activity; use current class context var activity:any =this; — Hemant Parmar

android.app.Activity is not an instance of the Activity, it's a class descriptor.

You can find information on accessing the current foreground activity at the official {N} docs: https://docs.nativescript.org/cookbook/application#tracking-the-current-activity

import * as app from "tns-core-modules/application";
const androidApp = app.android;

if (androidApp.foregroundActivity === androidApp.startActivity) {
    ////console.log("We are currently in the main (start) activity of the application");
}

could you tell me what is the activity context instance here?

pkanev Over a year ago

I just did - androidApp.foregroundActivity is the activity instance, activity extends context - meaning the activity instance IS also a context instance.
