Dear good morning, I am quite a novice in the development of mobile applications, I am learning and I need to be able to show a loading after launching my first image of the app in a Splash.

That is, I have an app that launches a Splash, it lasts approximately 2 seconds, while loading a url that contains the streaming that I must play when I start the app, it takes a while to load this url and during that moment I want to show a loading, how can I do it?

This is my final code.

public class MainActivity extends Activity implements OnClickListener {
  static MediaPlayer mPlayer;
    ImageButton buttonPlay;
    ImageButton buttonStop;
    String url = "url";
    Button btn_politica, btn_deportes, btn_espectaculo, btn_entretencion;
    ProgressBar progressbar;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);//analiza el archivo XML, traduce a objetos cada componente,
        progressbar = (ProgressBar) findViewById(R.id.mi_loading);
        onPrepared(mPlayer);
        //le asigna los atributos, establece contenedores y todas las relaciones
        //padre e hijo necesarias.

        //Bloque de coding para el streaming al cargar el activity
        mPlayer = new MediaPlayer();
        mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
        try {
            mPlayer.setDataSource(url);
        } catch (IllegalArgumentException e) {
            Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
        } catch (SecurityException e) {
            Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
        } catch (IllegalStateException e) {
            Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
        } catch (IOException e) {
            e.printStackTrace();
        }
        try {
            mPlayer.prepare();

        } catch (IllegalStateException e) {
            Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
        } catch (IOException e) {
            Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
        }
        mPlayer.start();
       //Finaliza bloque de codigo para cargar el streaming al inicio de la aplicacion+

        initialize();

        //Bloque de codigo para el streaming al presionar play
        buttonPlay = (ImageButton) findViewById(R.id.play);
        buttonPlay.setOnClickListener(new OnClickListener() {


            public void onClick(View v) {
                mPlayer = new MediaPlayer();
                mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
                try {
                    mPlayer.setDataSource(url);
                } catch (IllegalArgumentException e) {
                    Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
                } catch (SecurityException e) {

If you want to show a progressbar ("loading") while uploading your video, simply add it within a RelativeLayout and center it, you will make it invisible when it is ready or start playing the video.

setVisibility(View.INVISIBLE) or setVisibility(View.GONE)

This is an example layout:

<RelativeLayout
    android:id="@+id/Load_rly_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <VideoView
        android:id="@+id/streamingVideoView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        />

    <ProgressBar
            android:id="@+id/mi_loading"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true" />

</RelativeLayout>

When the video is ready to play is when you can make the ProgressBar invisible:

...
...
//Bloque de coding para el streaming al cargar el activity
    mPlayer = new MediaPlayer();
    mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    mPlayer.setOnPreparedListener(new OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer mp) {
            progressbar.setVisibility(View.INVISIBLE);
        }
    });
...
...
