Login on android opens up browser with an invalid Redirect URI

[Paramesh-C]

On making the login request, the app opens up browser with the following URL returns a response which mentions the redirect_uri doesn't match the registered URIs. (Happens when Pinterest Android APP is not installed)

https://api.pinterest.com/oauth/?client_id=+4926105309897833856&scope=read_public&redirect_uri=pdk+4926105309897833856%3A%2F%2F&response_type=token

{ status: "failure", message: "You are not permitted to access that resource.", code: 7, data: "The provided redirect_uri pdk 4926105309897833856:// does not match any of the registered redirect URIs." }

The pinterest currently allows only the redirect URIs which uses https:// protocol. While the redirect URI from the below request has something like pdk+4926105309897833856%3A%2F%2F. So the login is not working.
