How to connect your activity to its fragment


Often you will want one Fragment to communicate with its Activity also all Fragment-to-Fragment communication must be done through the associated Activity. Two Fragments should never communicate directly.

Define an Interface
To allow a Fragment to communicate up to its Activity, you can define an interface in the Fragment class and implement it within the Activity.

public class HeadlinesFragment extends ListFragment {
    OnHeadlineSelectedListener mCallback;

    // Container Activity must implement this interface
    public interface OnHeadlineSelectedListener {
        public void onArticleSelected(int position);

    public void onAttach(Activity activity) {
        // This makes sure that the container activity has implemented
        // the callback interface. If not, it throws an exception
        try {
            mCallback = (OnHeadlineSelectedListener) activity;
        } catch (ClassCastException e) {
            throw new ClassCastException(activity.toString()
                    + " must implement OnHeadlineSelectedListener");

Now the fragment can deliver messages to the activity by calling the onArticleSelected() method (or other methods in the interface) using the mCallback instance of the OnHeadlineSelectedListener interface.

Implement the Interface
In order to receive event callbacks from the fragment, the activity that hosts it must implement the interface defined in the fragment class.

public static class MainActivity extends Activity
        implements HeadlinesFragment.OnHeadlineSelectedListener{
    public void onArticleSelected(int position) {
        // The user selected the headline of an article from the HeadlinesFragment
        // Do something here to display that article

How to manage your Android Application Settings


Here is my best practice for managing your Android application settings using AppSettings class. by using this class you can save your different variables in shared preferences and also load them to ram when ever needed and use them in memory.

String methods sample:

AppSettings.setValue(this, KEY_NAME, name);
AppSettings.getString(this, KEY_NAME, "");
AppSettings.clearValue(this, KEY_NAME);
