我应该在哪里调用代码上的close()？

LogCat返回此错误:

从未在数据库android.database.sqlite.DatabaseObjectNotClosedException上显式调用close():应用程序未关闭此处打开的游标或数据库对象

错误是这样的:

嗨我已将我的应用程序上传到Play商店,但到目前为止它已准备好发布状态.为什么我无法理解这一点？我在2013年9月13日上传了我的应用程序.在左侧的附加图片中,您可以在apk,商店列表和定价与分布上打勾绿色.如果我没有履行任何部分,那么它将不会是绿色

你可以在截图上看到它.知道为什么吗？

嘿大家我已经找了几个小时试图找到解决方案,我的目标是当它打开另一个活动时有一个Listview.实际上,我得到它可以在点击时打开另一个活动,但我如何得到它,以便每个列表项将打开自己的活动？我非常抱歉,如果这个问题已经得到解答,但我找到的链接并没有真正描述代码在做什么[是的,我是新手:)

这是我正在使用的代码

@Override
    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

      String[] countries = getResources().getStringArray(R.array.countries_array);
      setListAdapter(new ArrayAdapter<String>(this, R.layout.newfile, countries));

      ListView lv = getListView();
      lv.setTextFilterEnabled(true);

      lv.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
          // When clicked, show a toast with the TextView text
             Intent myIntent = new Intent(view.getContext(), Html_file.class);
             startActivityForResult(myIntent, 0);

        }
      });
    }
}

我正在尝试在Android中的活动之间传递数组列表.列表包含字符串.我读过很多关于Parcelable的文章.我是否需要创建一个Parcelable来传递一个String数组列表？截至目前,我使用putStringArrayListExtra()和getSringArrayListExtra()通过意图传递列表.

这是我的一些代码.

Intent load = new Intent(getApplicationContext(), HelloTabWidget.class);
        load.putStringArrayListExtra("albums", albums);  
        load.putStringArrayListExtra("songs", songs);  
        load.putStringArrayListExtra("artists", artists); 
        load.putStringArrayListExtra("fileName", fileName);  

这是我的onCreate方法,用于获取数组列表的acticity.

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.songlist); 

    Bundle extras = getIntent().getExtras();
    isArtists = extras.getBoolean("artists");   
    isAlbums = extras.getBoolean("albums"); 
    isSongs = extras.getBoolean("songs");   

        Intent get = getIntent();  
        songs = get.getStringArrayListExtra("songs"); 
        artists = get.getStringArrayListExtra("artists");
        albums = get.getStringArrayListExtra("albums");
        fileName = get.getStringArrayListExtra("fileName"); 



    if(isArtists == true)       
        updateArtistsList(); 
    else if(isAlbums == true) 
        updateAlbumsList();  
    else if(isSongs == true) 
        updateSongList();    
}

检索列表的类应该从列表中的数据创建listView.每当我运行代码时,我都会在尝试制作列表时获得nullPointerExceptions.我知道我的listView代码工作,所以我已经将问题缩小到通过数组列表的意图.

提前致谢.

编辑:以下是logcat的前几行.

亲爱的大家,

我已成功使用Sencha touch 2创建了一个应用程序,它在我的Android设备上工作正常,也在平板电脑和模拟器上工作.但问题是apk文件无法在Android Market上传,它显示错误:

.apk is not signed also validity year 50 Error in Google market -: 
Google Play does not accept apks signed with the debug certificate. 
Create a new certificate that is valid for at least 50 years.

我已经更改了我的证书"配置":"发布"但没有取得任何成功.亲爱的我也在分享我的整个配置文件.如果您在配置文件中发现任何错误,请告诉我.任何建议表示赞赏.预先感谢.

配置文件中的代码是 - :

{
"applicationName":"navi",
"applicationId":"com.amit.navi",
"versionString":"1.0",
"iconName":"resources/icons/Icon~ipad.png",
"inputPath":"build/native",

"certificateAlias":"alias_name",
"sdkPath":"C:/android-sdk",

"orientations": [
"portrait",
"landscapeLeft",
"landscapeRight",
"portraitUpsideDown"
]
}

String slctsummary = "select   Reminder_Id,Reminder_Type,Reminder_Date,Reminder_Time,Reminder_Alert from Reminder_Main where Car_ID="
                +summaryid
                +"AND"
                +Reminder_Date 
                +"="
                +currentdate1;

        Cursor c = sdb.rawQuery(slctsummary,null);  

我希望所有的记录都满足conditn,但它通过错误.PLZ帮助我摆脱thnx ...

我存储ArrayList<Double>在我的bean类中,

我的主要活动是bean类,

如何将ArrayList<Double>我的主要活动传递给另一项活动.

我的数组列表是双倍的.如何通过双arraylist？
