我试着运行程序代码soundclouddroid https://code.google.com/p/soundclouddroid/source/browse/ 1.2.2.我有另一个问题之前，我解决了Stackoverflow，但现在我有一个，不明白为什么会发生。我的问题是：

java.lang.RuntimeException: Unable to start activity ComponentInfo {es.manu.sd122.soundCloudDroid/es.manu.sd122.soundCloudDroid.CustomTrackListsActivity}: java.lang.IllegalArgumentException: Unknown URI content :/ / is .manu.sd122.provider.soundCloudDroid/tracklists

该程序试图拉Souncloud数据。在Souncloud页面我创建了一个应用程序，我已经获得了客户端ID和客户端密码，我还添加了重定向URI字段，我已经设置为认证：http://es.manu.sd122.provider.soundCloudDroid。该网站添加了http：//声云网站。
你能帮帮我吗？谢谢

自定义跟踪列表活动

public class CustomTrackListsActivity extends ListActivity

        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.custom_track_lists);

        // Read uploads
        mCursor = getContentResolver().query(DB.TrackLists.CONTENT_URI, null, DB.TrackLists.RESOURCE + "<>\"\"", null, null);

        SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.track_list_item, mCursor,
                new String[] { DB.TrackLists.TITLE }, new int[] { android.R.id.text1 });
        setListAdapter(adapter);

        findViewById(R.id.use_menu).setVisibility(mCursor.getCount()<=2 ? View.VISIBLE : View.INVISIBLE);
    }

    public void onDestroy()
    {
        super.onDestroy();
        mCursor.close();
    }

    public boolean onCreateOptionsMenu(Menu menu)
    {
        super.onCreateOptionsMenu(menu);

        mArtistTracksMenuItem = menu.add("Search for Artists").setIcon(android.R.drawable.ic_menu_add);
        return true;
    }

    public boolean onOptionsItemSelected(MenuItem item) 
    {
        if(item == mArtistTracksMenuItem)
        {
            startActivity(new Intent(getApplication(), NewArtistTracksActivity.class));
            return true;
        }
        else return super.onOptionsItemSelected(item);
    }

    public void onListItemClick(ListView parent, View v, int position, long id)
    {
        mCursor.moveToPosition(position);
        Intent intent;
        if(id == 0)
            intent = new Intent(getApplication(), ViewTracksActivity.class);
        else
        {
            intent = new Intent(getApplication(), ViewOtherTracksActivity.class);
            intent.putExtra(DB.TrackLists.RESOURCE, mCursor.getString(1));
            intent.putExtra(DB.TrackLists.TITLE, mCursor.getString(2));
            intent.putExtra(DB.TrackLists._ID, id);
        }

        startActivity(intent);
    }

    private MenuItem mArtistTracksMenuItem;
    private Cursor mCursor;

}

我一直在寻找与Stackoverflow上的错误Unkown Uri Content相关的各种问题，但我仍然可以移动。
谢谢

我在其他开发人员身上也看到过同样的问题，但是LogCat中显示的错误消息中有

Caused by: java.lang.IllegalArgumentException: Unknown URI content://es.manu.sd122.provider.soundCloudDroid/tracklists
at es.manu.sd122.soundCloudBase.SoundCloudData.query(SoundCloudData.java:244)

未知的URI：

es.manu.sd122.provider.soundCloudDroid

因此必须更改为：

es.manu.sd122.soundCloudBase.SoundCloudData
