How to get data from other activity in android?

Question

I have two activities such as Activity A and B and I\'m trying to pass two different strings from A to B using Bundle and startActivity(inten

Answer 1

Here's another way to pass data between Activities. This is just an example from a tutorial I was following. I have a splash screen that runs for 5 seconds and then it would kill the sound clip from:

@Override
protected void onPause() {
    super.onPause();
    ourSong.release();
}

I decided I wanted the sound clip to continue playing into the next activity while still being able to kill/release it from there, so I made the sound clip, MediaPlayer object, public and static, similar to how out in System.out is a public static object. Being new to Android dev but not new to Java dev, I did it this way.

import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;

public class Splash extends Activity {

    public static MediaPlayer ourSong; // <----- Created the object to be shared
                                        // this way

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);
        ourSong = MediaPlayer.create(Splash.this, R.raw.dubstep);
        ourSong.start();
        Thread timer = new Thread() {
            public void run() {
                try {
                    sleep(5000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                } finally {
                    Intent openStartingPoint = new Intent(
                            "expectusafterlun.ch.androidtutorial.MENU");
                    startActivity(openStartingPoint);
                }
            }
        };
        timer.start();
    }
}

Then from the next activity, or any other activity, I could access that MediaPlayer object.

public class Menu extends ListActivity {

    String activities[] = { "Count", "TextPlay", "Email", "Camera", "example4",
            "example5", "example6" };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setListAdapter(new ArrayAdapter(Menu.this,
                android.R.layout.simple_expandable_list_item_1, activities));
    }

    @Override
    protected void onPause() {
        super.onPause();
        Splash.ourSong.release(); // <----- Accessing data from another Activity
                                    // here
    }

}
