Answer 1

  Intent shareIntent = new Intent(Intent.ACTION_SEND);
  shareIntent.setType("text/plain");
  shareIntent.putExtra(Intent.EXTRA_TEXT, "URLyouWantToShare");
  startActivity(Intent.createChooser(shareIntent, "Share..."));

Use the ACTION_SEND Intent, add the URL you want to share. User will be given a selection of apps to accept the share intent such as facebook etc.
