How do I pass data between two activities in Android?

Question

VIDEO ACTIVITY

with the code that you gave me to be included in videoactivity me an error on the url at the line private String VIDEO = url; tells me that url can not be resolved to a variable

public class VideoActivity extends YouTubeBaseActivity implements
YouTubePlayer.OnInitializedListener {

static private final String DEVELOPER_KEY = "AIzaSyBR-QH8hCO8U_WE_sIPGhEQIGmBEYCi7pQ";

private String VIDEO = url;

   @Override
    protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.videoactivity);
          YouTubePlayerView youTubeView = (YouTubePlayerView)
                  findViewById(R.id.youtube_video);
       youTubeView.initialize(DEVELOPER_KEY, this);
       Bundle bundle = getIntent().getExtras();
       final String url = bundle.getString("url1");

   }


   public void onInitializationFailure(Provider provider,
YouTubeInitializationResult error) {
            Toast.makeText(this, "Oh no! Errore di Connessione, provi a rientrare"+error.toString(),
Toast.LENGTH_LONG).show();
   }
   @Override
   public void onInitializationSuccess(Provider provider, YouTubePlayer player,
boolean wasRestored) {
          player.loadVideo(VIDEO);
   }

}

@john : `"key"` can be any string it can also be `"url"` and your `"value"` is supposed to the actual `url` — Sagar Pilkhwal, Sep 07 '14 at 19:12

Use:

Intent video = new Intent(EpisodiActivity.this,VideoActivity.class);
video.putExtra("url", "value");
startActivity(video);

so likewise in you class:

mylist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
        Intent video = new Intent(EpisodiActivity.this,VideoActivity.class);
        String urlFromListView=(String)arg0.getItemAtPosition(position);
        video.putExtra("url",urlFromListView);
        startActivity(video);
    }
});

To Retrieve it in VideoActivity:

inside onCreate(Bundle savedInstanceState) after setContentView(R.layout.videoactivity);

Bundle bundle = getIntent().getExtras();
final String url = bundle.getString("url");

and the url where should I put them? – john Sep 07 '14 at 20:16
url of youtube video – john Sep 07 '14 at 20:20
so u have a list of youtube video `url`, when you click on any list item, see my answer it will start `VideoActivity` answer send the `url` and in `VideoActivity` use `Bundle bundle = getIntent().getExtras(); final String key = bundle.getString("key");` – Sagar Pilkhwal Sep 07 '14 at 20:24
sorry but you have not answered my earlier question, where do I insert the url? – john Sep 07 '14 at 20:28
in `video.putExtra("url",urlFromListView);` `urlFromListView` is your url – Sagar Pilkhwal Sep 07 '14 at 20:30
excuse me but I'm trying, but is full of mistakes, could you show me a example with 2 url in case please? – john Sep 07 '14 at 20:36
no are more than 2, is a random number :) – john Sep 07 '14 at 20:43
`video.putExtra("url1",urlFromListView);` and `video.putExtra("url2",urlFromListView);` and in `VideoActvity` `Bundle bundle = getIntent().getExtras();` `final String url1 = bundle.getString("url1");` and `final String url2 = bundle.getString("url2");` – Sagar Pilkhwal Sep 07 '14 at 20:43
you can directly pass the string array object and then in `VideoActivity` `bundle.getStringArray("url")` – Sagar Pilkhwal Sep 07 '14 at 20:46
ok let's see if I understand if for example the url are 10 I have to do ten of these lines video.putExtra ("url1" urlFromListView); , Changing only the number of the url? and the same thing I have to do it well in videoactivity? – john Sep 07 '14 at 20:46
you can pass `url[]` remember `"urlArray"` this is just a name you give its not a keyword `video.putExtra("urlArray",urlArray);` – Sagar Pilkhwal Sep 07 '14 at 20:50
sorry I do not understand a thing but I have to put the url in place of url2 or urlFromListView? – john Sep 07 '14 at 20:50
sorry I'm doing a bit of confusion you show me an example of code please, so I can vote you the answer :) – john Sep 07 '14 at 20:52
try [this link](http://www.androidbegin.com/tutorial/android-custom-listview-texts-tutorial/), its very simple and self explanatory. – Sagar Pilkhwal Sep 08 '14 at 06:26
ok I miss only one thing to understand now, in videoactivity if I write the code that you gave me tells me that the local variable url is not used. what do I do? but here, VIDEO private String = ??? I have to put this "url" or without quotes – john Sep 08 '14 at 09:32
use `private String VIDEO = "";` & `VIDEO = bundle.getString("url1");` – Sagar Pilkhwal Sep 08 '14 at 09:52
