import android.app.Activity;

// 播放

}

最后因为播放是网络视频千万不要忘了添加访问网络权限，

<uses-permission android:name="android.permission.INTERNET" />

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

<uses-permission android:name="android.permission.READ_LOGS" />

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<uses-permission android:name="android.permission.WRITE_SETTINGS" />

<uses-permission android:name="android.permission.WAKE_LOCK" />
