这是我的代码：

            Intent i= getIntent(); // gets the previously created intent
            Log.d(LOG_TAG, "PodcastSong (1):"+i.getStringExtra("PodcastSong"));

  }

以下是错误：

这是ipod等应用程序...当我想在用户点击播放图标后播放播客时出现错误...但它不适用于某些文件/歌曲...我无法' t识别代码或数据库中的问题。

Answer 1

song.put("image_url", arrSong[7]);

它抛出java.lang.ArrayIndexOutOfBoundsException: length=7; index=7

由于有些歌曲没有任何图像，因此它不包含image_url。因此，在你的arrSong中，这个位置将为null。

您可以try/Catch使用ArrayIndexOutOfBoundsException。

e.g

    try {
                song.put("image_url", arrSong[7]);

        } catch (ArrayIndexOutOfBoundsException e) {
            // TODO: handle exception
                  song.put("image_url","No Image");
        }

媒体播放器无法在某些播客列表中使用
