Answer 1

Installing isn't too hard. You can put the second .apk file in the assets or raw resources folder of your first app. Then, when the first app runs, it can copy the .apk file to a temporary location and install the second app with something like this (lifted from this thread):

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(
    new File(Environment.getExternalStorageDirectory() + "/download/" + "app.apk")),
    "application/vnd.android.package-archive");
startActivity(intent);

Uninstalling is a little more complicated. You can't actually do what you want directly; you'll probably need a third app. It can register itself to receive ACTION_PACKAGE_REMOVED broadcasts and when it receives a broadcast that the first app is being removed, can remove the second app.

See this blog post for more details, including some settings that might be needed on the phone for non-market apps.

Answer 2

It won't be an .apk rather you can create your another Application as Android Library. You can keep your Project as Library and can put in or use into Another Applications.
