Spotify Android Intent Play on Launch

Question

我试图让 Spotify 在从意图启动时恢复播放，但运气不佳。我想我已经很接近了，我可以让 Spotify 启动，如果我指定搜索艺术家，它将自动播放，但实际上我只是希望它恢复我上次播放的内容，但我还没有开始工作。这个网站使它看起来成为可能，但到目前为止，Spotify 刚刚启动并进入搜索屏幕。 http://developer.android.com/guide/components/intents-common.html#PlaySearch

到目前为止，这是我的代码：

        final Intent intent1 = new Intent(MediaStore.INTENT_ACTION_MEDIA_PLAY_FROM_SEARCH);
        intent1.setComponent(new ComponentName("com.spotify.music", "com.spotify.music.MainActivity"));
        intent1.putExtra(MediaStore.EXTRA_MEDIA_FOCUS, "vnd.android.cursor.item/*");
        intent1.putExtra(SearchManager.QUERY, "");
        intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        if (intent1.resolveActivity(getPackageManager()) != null) {
            startActivity(intent1);
        }

我花了一段时间才弄清楚这一点，所以我想我会发布我使用的解决方案。我遍历了所有订阅 Intent.ACTION_MEDIA_BUTTON 的包，这时我找到了让它工作所需的组件名称：

private void playPlayMusic() {
    Intent i = new Intent(Intent.ACTION_MEDIA_BUTTON);
    i.setComponent(new ComponentName("com.spotify.music", "com.spotify.music.internal.receiver.MediaButtonReceiver"));
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PLAY));
    sendOrderedBroadcast(i, null);

    i = new Intent(Intent.ACTION_MEDIA_BUTTON);
    i.setComponent(new ComponentName("com.spotify.music", "com.spotify.music.internal.receiver.MediaButtonReceiver"));
    i.putExtra(Intent.EXTRA_KEY_EVENT,new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PLAY));
    sendOrderedBroadcast(i, null);
}

这是按艺术家搜索并在 Spotify 中播放的例程：

public void playSearchArtist(String artist) {
    Intent intent = new Intent(MediaStore.INTENT_ACTION_MEDIA_PLAY_FROM_SEARCH);
    intent.setComponent(new ComponentName("com.spotify.music", "com.spotify.music.MainActivity"));
    intent.putExtra(MediaStore.EXTRA_MEDIA_FOCUS, MediaStore.Audio.Artists.ENTRY_CONTENT_TYPE);
    intent.putExtra(MediaStore.EXTRA_MEDIA_ARTIST, artist);
    intent.putExtra(SearchManager.QUERY, artist);
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent);
    }
}
