android, uninstall and install into the same activity?

I am trying to do an upgrade version process for apk files ...

How can i do to run uninstall and install Intent calls into the same activity?

If i do , uninstall intent,

Uri packageURI = Uri.parse("package:" + paqueteId);

    Intent uninstallIntent = new Intent(Intent.ACTION_DELETE,packageURI);

    startActivityForResult(uninstallIntent, RESULT_OK);

is there anyway to wait for the uninstall finish and then continue running the activity code ... and then launch the install intent ???

thank you
