我有一个类似的应用，其代码非常相似，可以播放YouTube视频，但不会。我试图从Google获得一个不同的API KEY，但这没有什么不同。 当我单击启动YouTube播放器的按钮时，该应用程序便崩溃了。
这是java类：
package xxxxxxxxxxxxxxxxxxx;
import android.os.Bundle;
import android.widget.Toast;
import com.google.android.youtube.player.YouTubeBaseActivity;
import com.google.android.youtube.player.YouTubeInitializationResult;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayer.Provider;
import com.google.android.youtube.player.YouTubePlayerView;
public class Level_1_Training extends YouTubeBaseActivity implements
YouTubePlayer.OnInitializedListener{
public static final String API_KEY = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
public static final String VIDEO_ID = "Bm7WMvpjDec";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video);
YouTubePlayerView youTubePlayerView = (YouTubePlayerView)findViewById(R.id.youtubeplayerview);
youTubePlayerView.initialize(API_KEY, this);
}
@Override
public void onInitializationFailure(Provider provider,
YouTubeInitializationResult result) {
Toast.makeText(getApplicationContext(),
"onInitializationFailure()",
Toast.LENGTH_LONG).show();
}
@Override
public void onInitializationSuccess(Provider provider, YouTubePlayer player,
boolean wasRestored) {
player.setPlayerStyle(YouTubePlayer.PlayerStyle.MINIMAL);// it's a simple style that doesn't show the YouTube logo and it prevents users to find the real source of the YouTube video
if (!wasRestored) {
player.cueVideo(VIDEO_ID);
}
}
}
并显示：
