Android 4.4 上的 IBM Worklight 6.1 JsonStore 问题

Question

我已升级到 Worklight 6.1，我期待我在此处提到的问题 IBM Worklight Android 4.4 issue, JSON Store stopped working 将得到解决，并且我的应用程序现在应该可以正常工作了。但仍然面临 Android 4.4 中的 JSONStore 初始化问题。请检查以下日志。

Answer 1

尝试以下方法：

• 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
• 确保从您的 Android 环境下的 native 文件夹中删除 armeabi/libdatabase_sqlite.so、x86/libdatabase_sqlcipher.so 和 sqlcipher.jar。请参阅您关心的文件下的图片。
• 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 回来了。查看仅供参考部分了解更多详情。
• 在 Eclipse 上刷新原生 Android 项目。
• 在模拟器或设备上运行。

仅供参考

我的机器 (Mac OSX 10.9) 上工作库的大小和 MD5 哈希值。大小由ls -al 确定，MD5 哈希由md5 [file] 生成。

sqlcipher.jar

Size: 103300 
MD5 Hash: 8d7f4d682994158096763c24e3d79fb2 

armeabi/libdatabase_sqlite.so

x86/libdatabase_sqlcipher.so

您关心的文件：

还是不行？

• 使用 v6.1 创建新的 Worklight 项目（不适用于其他版本）。
• 创建一个新的混合应用程序。
• 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 armeabi/libdatabase_sqlite.so、x86/libdatabase_sqlcipher.so 和 sqlcipher.jar 从在 Android v4.4 中工作的新创建项目复制到现有项目。确保在将应用程序发送到设备或模拟器之前构建、卸载应用程序的早期版本并刷新本机项目。

我正在运行一个过时版本的库。使用 2.2.2 对我来说适用于 4.4。 从here下载
