I have done this using webView.

webview = (WebView) findViewById(R.id.webView1);

WebSettings settings = webview.getSettings();
settings.setBuiltInZoomControls(true);
settings.setUseWideViewPort(false);
settings.setJavaScriptEnabled(true);
settings.setSupportMultipleWindows(false);

settings.setLoadsImagesAutomatically(true);
settings.setLightTouchEnabled(true);
settings.setDomStorageEnabled(true);
settings.setLoadWithOverviewMode(true);

WebView webview = (WebView) findViewById(R.id.webview);
WebView.enableSlowWholeDocumentDraw();

String RESULTDATA = "<html><body><h1>It's working</h1></body></html>";
if (!RESULTDATA.equals(null)) {
    Log.e("info", RESULTDATA);
    webview.loadData(RESULTDATA, "text/html", null);
}

circleButton.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {

        shareResultAsImage(webview);
    }
});

And shareResultAsImage(WebView) method need to define.

private void shareResultAsImage(WebView webView) {
    Bitmap bitmap = getBitmapOfWebView(webView);
    String pathofBmp = MediaStore.Images.Media.insertImage(getContentResolver(), bitmap, "data", null);
    Uri bmpUri = Uri.parse(pathofBmp);
    final Intent emailIntent1 = new Intent(android.content.Intent.ACTION_SEND);
    emailIntent1.setType("image/png");
    emailIntent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    emailIntent1.putExtra(Intent.EXTRA_STREAM, bmpUri);

    startActivity(emailIntent1);
}

private Bitmap getBitmapOfWebView(final WebView webView) {
    Picture picture = webView.capturePicture();
    Bitmap bitmap = Bitmap.createBitmap(picture.getWidth(), picture.getHeight(), Bitmap.Config.RGB_565);
    Canvas canvas = new Canvas(bitmap);
    canvas.drawColor(Color.WHITE);
    picture.draw(canvas);
    return bitmap;
}

This is exactly what I needed, however, I noticed that there is a loss of quality in the image generated from the webview, the text contained in it becomes a bit blurred, any idea why this could be happening? — FabioR, Oct 20 '20 at 18:11

There can be many possible solutions. You can achieve it somehow by showing the full screen web view and programmatically capturing the screen shot of device and sending the data through a background service.
For capturing screenshot through program ; you can use following link:
