Android 4.4上的IBM Worklight 6.1 JsonStore问题

Question

我已升级到Worklight 6.1＆amp;我期待我在这里提到的问题IBM Worklight Android 4.4 issue, JSON Store stopped working将得到解决，我的应用程序现在应该可以正常工作。但仍面临Android 4.4中的JSONStore初始化问题。请检查下面的日志。

Answer 1

请尝试以下操作：

• 卸载应用程序（只是为了确保没有缓存任何内容）
• 转到application-descriptor.xml
• 删除JSONStore可选功能
• 构建
• 确保从Android环境下的armeabi/libdatabase_sqlite.so文件夹中删除x86/libdatabase_sqlcipher.so，sqlcipher.jar和native。请参阅下面的您关注的文件下的图片。
• 转到application-descriptor.xml
• 启用JSONStore可选功能
• 构建
• 确保armeabi/libdatabase_sqlite.so，x86/libdatabase_sqlcipher.so和sqlcipher.jar返回。请查看 FYI 部分了解更多详情。
• 在Eclipse上刷新原生Android项目。
• 在模拟器或设备上运行。

您关注的文件：

仍然无效？

• 使用v6.1创建一个新的Worklight项目（不适用于其他版本）。
• 创建新的混合应用程序。
• 创建Android环境。
• 转到application-descriptor.xml
• 启用JSONStore。
• 构建
• 确认JSONStore在那里工作。

这是一个简单的例子：

var collections = {
    customers : {
      searchFields : {
        'CUSTOMERCODE' : 'string'
      }
    }
  };

  WL.JSONStore.init(collections)

  .then(function () {
    return WL.JSONStore.get('customers').add({'CUSTOMERCODE' : '456'});
  })

  .then(function () {
    return WL.JSONStore.get('customers').findAll();
  })

  .then(function (res) {
    alert(JSON.stringify(res));
  })

  .fail(function (err) {
    alert(err.toString());
  });
});

• 将新版本的适用于Android v4.4的项目中的armeabi/libdatabase_sqlite.so，x86/libdatabase_sqlcipher.so和sqlcipher.jar复制到现有项目中。在将其发送到设备或模拟器之前，请确保构建，卸载以前版本的应用程序并刷新本机项目。

我正在运行一个过时的lib版本。使用2.2.2对我来说是4.4。 从here下载
