2. 開始前
需要申請API Key
需要SHA-1碼

3. 透過packagename與SHA-1碼申請金鑰

4. UI Design

5. <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_marginTop="10dp"
android:layout_height="wrap_content"
android:gravity="center"
android:text="YouTubePlayer"/>
<com.google.android.youtube.player.YouTubePlayerView
android:layout_marginBottom="10dp"
android:layout_height="wrap_content"/>
</LinearLayout>

6. 引用JAR函式庫

7. YouTubeAndroidPlayerApi.jar

8. Add as library

9. build.gradle(app)

10. Code

11. 繼承YouTubePlayer.OnInitializedListener並implement method

12. 修改成使用YouTubeBaseActivity

13. 設定API KEY與VIDEO ID // 設定API Key
public static final String API_KEY = “xxxxxxx";
// 設定youtube video id
private String VIDEO_ID = "gd38-X3HpbM";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// 取得youtube顯示物件
YouTubePlayerView youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);
// 初始化youtube物件
youTubeView.initialize(API_KEY, this); }

14. 初始化成功開始撥放影片 @Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
if (!b) {
// loadVideo() will auto play video
// Use cueVideo() method, if you don't want to play it automatically
youTubePlayer.loadVideo(VIDEO_ID);
// Hiding player controls
//youTubePlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.CHROMELESS); }

15. 初始化失敗 private static final int RECOVERY_DIALOG_REQUEST = 10; @Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
if (youTubeInitializationResult.isUserRecoverableError()) {
youTubeInitializationResult.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
} else {
String errorMessage = String.format("YouTube Error (%1$s)",
youTubeInitializationResult.toString());
Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show(); }

16. 取得啟動失敗的回應
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == RECOVERY_DIALOG_REQUEST) {
// Retry initialization if user performed a recovery action
getYouTubePlayerProvider().initialize(API_KEY, this); }
protected YouTubePlayer.Provider getYouTubePlayerProvider() {
return (YouTubePlayerView) findViewById(R.id.youtube_view);

17. 加入網路使用權限
<uses-permission android:name="android.permission.INTERNET" />
