When a user presses Enter in the username or password field of the LoginActivity (possible in Swiftkey, can't speak for AOSP keyboard), he is directed to the redirect URL of his API with an access denied info in the URL params.

This triggers the parsing of the TokenURL but crashes the Matcher (because obviously, there are no tokens to be found).

Surrounding the matching parts with try/catch and setting the WebView URL to the original one in the catch part - together with a Toast for the user reminding him to click on allow - is a hacky but quick way to solve the problem.

As this part will probably the most copied one, a fix would be great. Another question: Is the API actually working as it should if it redirects the user even when access is denied?

Other than that, I really enjoy working with your API, keep the great work up!

Cheers,

When trying to login, I get a force close no matter what I do:

• run app, substituting real ID and Secret before compilation
• Click on overflow icon to Login
• select any of the four options, and click Allow -> FC
  or
• enter a user/pass combination, and click Allow -> FC

A similar stack trace for each try:

I'm trying to authenticate using Scribe in my app, but having a bit of trouble understanding the workflow (I assumed I'd get a response directly, rather than requiring a webview or something).
