How to build this app?

This app using 3rd party's free api for backend. So you need to register this api to get accesskey and secretkey :(

If you get your accesskey and secretkey, create secret.properties file in project root like following.

accesskey={your access key comes here}
secretkey={your secret key comes here}

Then these values are read in compiltime and used when this app calling api.

If you want to try login-needed feature (ex. like/unlike photo, edit user info), Go your app page and edit "Redirect URI & Permissions" section

1. add ishikota://mysite.com/callback to "Redirect URI" section
2. check all items (ex. "Public access", "Write likes access")
