@override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);           // add custom view action bar         webview = (webview) findviewbyid(r.id.webview1);         webview.getsettings().setjavascriptenabled(true);         webview.getsettings().setbuiltinzoomcontrols(true);          if(build.version.sdk_int < build.version_codes.jelly_bean_mr2)                     webview.getsettings().setpluginstate(websettings.pluginstate.on);           webview.setwebviewclient(new webviewclient () {             @ override             public boolean shouldoverrideurlloading(webview view, string url) {             if (url.startswith("vnd.youtube")){                  startactivity(new intent(intent.action_view, uri.parse(url)));                  return true;             }             else return false;              }         });          webview.setwebchromeclient(new webchromeclient());         webview.getsettings().setusewideviewport(true);         //webview.getsettings().setusewideviewport(false);         webview.setscrollbarstyle(webview.scrollbars_outside_overlay);         webview.loadurl(url);      } 

1. go google developer console , select or create new project.

2. on left sidebar, select apis under apis & auth , turn status on youtube data api v3.

3. on left sidebar, select credentials , create new key under public api access.

4. when popup comes asking choose platform, select android key.

5. paste sha-1 key , project’s package name separated semicolon(;).

6. click on create. should see api key on dashboard.

create layout this

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent">  <com.google.android.youtube.player.youtubeplayerview     android:id="@+id/youtube_player"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="@color/black"     android:layout_centerinparent="true" />    </relativelayout> 

your activity should this

public class customyoutubeplayer extends youtubebaseactivity implements   youtubeplayer.oninitializedlistener{   private string api_key="your key"; private string video_id;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     /** attaching layout xml **/     setcontentview(r.layout.youtube_player);      /** initializing youtube player view **/     video_id = getintent().getextras().getstring(finalvariables.youtube_id);     youtubeplayerview youtubeplayerview = (youtubeplayerview) findviewbyid(r.id.youtube_player);     youtubeplayerview.initialize(api_key, this); }  @override public void oninitializationsuccess(provider provider, youtubeplayer player, boolean wasrestored) {      player.setshowfullscreenbutton(false);     /** add listeners youtubeplayer instance **/     player.setplayerstatechangelistener(playerstatechangelistener);     player.setplaybackeventlistener(playbackeventlistener);      /** start buffering **/     if (!wasrestored) {         player.loadvideo(video_id);     } } private youtubeplayer.playbackeventlistener playbackeventlistener = new youtubeplayer.playbackeventlistener() {      @override     public void onbuffering(boolean arg0) {     }      @override     public void onpaused() {     }      @override     public void onplaying() {     }      @override     public void onseekto(int arg0) {     }      @override     public void onstopped() {     }  };   private youtubeplayer.playerstatechangelistener playerstatechangelistener = new youtubeplayer.playerstatechangelistener() {      @override     public void onadstarted() {     }      @override     public void onerror(youtubeplayer.errorreason arg0) {     }      @override     public void onloaded(string arg0) {     }      @override     public void onloading() {     }      @override     public void onvideoended() {         finish();     }      @override     public void onvideostarted() {     } }; }  

just pass video id , that's simple that..

edit

if youtube link https://www.youtube.com/watch?v=rql_f8h3h9e video_id=rql_f8h3h9e extract video id youtube link , sent activity variable.
