推荐答案

请尝试以下操作：

• 卸载应用程序（只是为了确保没有任何内容）缓存）


• 转到application-descriptor.xml


• 删除JSONStore可选功能


• Build


• 确保 armeabi / libdatabase_sqlite.so ， x86 / libdatabase_sqlcipher.so 和 sqlcipher.jar 将从Android环境下的 native 文件夹中删除。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 又回来了。请查看 FYI 部分了解更多详情。


• 刷新Eclipse上的原生Android项目。


• 在模拟器上运行或者设备。

• Uninstall the application (just to make sure nothing is being cached)
• Go to the application-descriptor.xml
• Remove the JSONStore optional feature
• Build
• Make sure armeabi/libdatabase_sqlite.so, x86/libdatabase_sqlcipher.so and sqlcipher.jar are removed from the native folder under your Android environment. See the picture below under Files you care about.
• Go to application-descriptor.xml
• Enable the JSONStore optional feature
• Build
• Make sure armeabi/libdatabase_sqlite.so, x86/libdatabase_sqlcipher.so and sqlcipher.jar are back. Look at the FYI section for more details.
• Refresh the native Android project on Eclipse.
• Run on an emulator or device.

FYI

我的机器上的大小和MD5哈希值（Mac OSX 10.9）用于工作库。大小是用 ls -al 确定的，MD5哈希是用 md5 [file] 生成的。

The size and MD5 hashes on my machine (Mac OSX 10.9) for the working libraries. Size was determined with ls -al and the MD5 hash was generated with md5 [file].

sqlcipher.jar

您关注的文件：

仍然无效？

• 使用v6.1创建一个新的Worklight项目（赢了不能与其他版本一起使用。）


• 创建一个新的混合应用程序。


• 创建一个Android环境。


• 转到application-descriptor.xml


• 启用JSONStore。


• 构建。


• 确认JSONStore在那里工作。

• Create a new Worklight Project with v6.1 (won't work with other versions).
• Create a new Hybrid Application.
• Create an Android environments.
• Go to the application-descriptor.xml
• Enable JSONStore.
• Build.
• Confirm JSONStore works there.

以下是一个简单示例：

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());
  });
});

• 复制 armeabi / libdatabase_sqlite.so ， x86 / libdatabase_sqlcipher.so 和 sqlcipher.jar 来自Android中新创建的项目v4.4到你现有的项目。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。


• Copy armeabi/libdatabase_sqlite.so, x86/libdatabase_sqlcipher.so and sqlcipher.jar from that newly created project that works in Android v4.4 to your existing project. Make sure you build, uninstall a previous version of the app and refresh the native project before you send it to the device or emulator.
