如何从活动返回上一个Webview页面

Question

I have a WebView and it will open another activity code in my Webview client

if (Uri.parse(url).toString().contains(".mp3")) {

    Intent intent = new Intent(MainActivity.this,Download.class);
    intent.putExtra("Link",Uri.parse(url).toString());
    intent.putExtra("Link2",myWebview.getOriginalUrl().toString());

    startActivity(intent);
    finish();
}

Now As this intent extra will pass the value of the url from where the next Download.class is started

what I need is on onBackPressed() it will open the url from where Download .class was opened

This is my onBackPressed() code in Download.class

Intent i = new Intent(Download.this, MainActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
finish();
