Answer 1

You can use startActivityForResult method

try 
{
  Intent viewIntent = new Intent("android.intent.action.VIEW",
  Uri.parse("https://play.google.com/store/apps/details?id=your.app.id.here"));
  startActivityForResult(viewIntent, 1);
}
catch(Exception e) 
{
  Toast.makeText(getApplicationContext(),"Unable to Connect Try Again...",Toast.LENGTH_LONG).show();
  e.printStackTrace();
}

Use onActivityresult method to get result

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) 
{
   super.onActivityResult(requestCode, resultCode, data);
   switch (requestCode) {
        case (1):
            if (resultCode == Activity.RESULT_OK) 
            {
               //Do your stuff here
            }
}

Answer 2

You'll want to use

market://details?id=<package_name>

Rather than

http://play.google.com/store/apps/details?id=<package_name>

As a url linking to an app.
