Try the following:

试试以下:

• Uninstall the application (just to make sure nothing is being cached)
• 卸载应用程序(确保没有缓存)
• Go to the application-descriptor.xml
• 去application-descriptor.xml
• Remove the JSONStore optional feature
• 删除JSONStore可选特性
• Build
• 构建
• 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.
• 确保armeabi / libdatabase_sqlite。所以,x86 / libdatabase_sqlcipher。所以,sqlcipher。jar从Android环境下的本机文件夹中删除。在你关心的文件下面看到图片。
• Go to application-descriptor.xml
• 去application-descriptor.xml
• Enable the JSONStore optional feature
• 启用JSONStore可选特性
• Build
• 构建
• Make sure armeabi/libdatabase_sqlite.so, x86/libdatabase_sqlcipher.so and sqlcipher.jar are back. Look at the FYI section for more details.
• 确保armeabi / libdatabase_sqlite。所以,x86 / libdatabase_sqlcipher。所以,sqlcipher。jar又回来了。有关更多细节，请参阅参考资料部分。
• Refresh the native Android project on Eclipse.
• 在Eclipse上刷新本机Android项目。
• Run on an emulator or device.
• 在模拟器或设备上运行。

Still not working?

还不工作吗?

• Create a new Worklight Project with v6.1 (won't work with other versions).
• 使用v6.1创建一个新的Worklight项目(不会与其他版本一起使用)。
• Create a new Hybrid Application.
• 创建一个新的混合应用程序。
• Create an Android environments.
• 创建一个Android环境。
• Go to the application-descriptor.xml
• 去application-descriptor.xml
• Enable JSONStore.
• 启用JSONStore。
• Build.
• 构建。
• Confirm JSONStore works there.
• 确认JSONStore作品。

Here's a quick example:

这里有一个简单的例子:

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());
  });
});

• 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.
• armeabi / libdatabase_sqlite副本。所以,x86 / libdatabase_sqlcipher。所以,sqlcipher。在Android v4.4中工作的新创建项目jar到您的现有项目。在将应用程序发送到设备或模拟器之前，请确保构建、卸载以前的应用程序版本并刷新本机项目。
