A function I drag between projects to easily manage Fragments in Android.

MyClass.java

	public class MyClass extends FragmentActivity {
		/**
		 *
		 * Simple Fragment management. Lets you easily add Fragments.
		 *
		 * @param fragment Fragments to be added on top of the stack
		 * @param tag The Fragments tag. Can be null.
		 * @param clearStack If true, it will clear all existing Fragments from the
		 *                   stack.
		 */
		public void addFragment (Fragment fragment, String tag, boolean clearStack) {
			final FragmentManager fm = super.getSupportFragmentManager();
			final FragmentTransaction transaction = fm.beginTransaction();

			if (clearStack) {
				for (int x = 0; x < fm.getBackStackEntryCount(); x++) {
					fm.popBackStack();
				}
			}

			if (fragment != null) {
				transaction.replace(R.id.container, fragment, tag);
				if (!clearStack) {
					transaction.addToBackStack(null);
					transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
				}

				transaction.commit();
			}
		}

		public void addFragment (Fragment fragment) {
			addFragment(fragment, null, false);
		}

		public void addFragment (Fragment fragment, String tag) {
			addFragment(fragment, tag, false);
		}
	}
