It can be used to display page or when we have app open then it will shown status of work being complete.Progressbar class provide method to work on progress bar like setProgress(),setMessage,setProgressStyle(),show() etc. Below example will described you how to make Animated Progressbar in android.

Step(1)-Main.Layout-

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity"
    android:background="#006699">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Inder"
        android:id="@+id/textView"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true"
        android:textColor="#ffffff" />

    <ProgressBar
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/progressBar"
        android:layout_alignBottom="@+id/textView"
        android:layout_centerHorizontal="true" />

</RelativeLayout>

Step(2)-MainActivity-

public class MainActivity extends Activity {

    private static final String TAG ="buckyMessage";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Log.i(TAG,"onCreate");
    }
    @Override
    protected void onStart(){
        super.onStart();
        Log.i(TAG,"onStart");
    }
    @Override
    protected void onResume(){
        super.onResume();
        Log.i(TAG,"onResume");
    }
    @Override
    protected void onPause(){
        super.onPause();
        Log.i(TAG,"onPause");
    }
    @Override
    protected void onStop(){
        super.onStop();
        Log.i(TAG,"onStop");
    }
    @Override
    protected void onRestart(){
        super.onRestart();
        Log.i(TAG,"onRestart");
    }

    @Override
    protected  void onSaveInstanceState(Bundle outState){
         super.onSaveInstanceState(outState);
        Log.i(TAG,"onSaveInstanceState");
    }
    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState){
        super.onRestoreInstanceState(savedInstanceState);
        Log.i(TAG,"onRestoreInstanceState");
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}
