Not working on Android 8.0 Oreo

[ujeenator]

Facebook login fails with "Sorry something went wrong" message

Google login just hangs after entering the password

[SailingSteve]

With 8.0, for me in OAuthManagerModule.java

private WritableMap accessTokenResponse()

receives a OAuth2AccessToken that looks more like a payload from a URL separated by ampersands (not Json) and the GSON parser crashes on receiving it in about line 404. Even if it were properly formatted Json, it would not contain the "user_id" that we need.

Map accessTokenMap = new Gson().fromJson(accessToken.getRawResponse(), Map.class);

I backed down to 7.1 and avoided this crash.

I'm seeing possibly the same issue on Android 6.0. Logcat:

I don't think it's Android-version specific. The code in question is:

    Map accessTokenMap = new Gson().fromJson(accessToken.getRawResponse(), Map.class);

and accessToken.getRawResponse() looks like this (from a Twitter transaction, and with newlines added for ease of reading):

auth_token=9999999999-AAAAAAAAAAAAAAAAAAAAAAA&
oauth_token_secret=AAAAAAAAAAAAAAAAAAAAAA
&user_id=9999999999
&screen_name=mytwittername
&x_auth_expires=0

so the issue is as @SailingSteve reports that the code is expecting JSON back and it's getting a querystring (x-www-form-urlencoded) instead. What I don't understand is how this ever worked -- https://developer.twitter.com/en/docs/basics/authentication/api-reference/access_token is clear that oauth tokens are returned as a querystring. So I must be missing something.

(I think that https://github.com/fullstackreact/react-native-oauth/commit/2a1c0fbb13dc43d09bde267c3ff969034b60a559#diff-9fc211ef231ecaa3ee7613d9696db4a1 is the commit which changed code to parse the response as JSON, instead of as a querystring.)
