    Yes, OAuth 2 access tokens only have one piece. That is, each OAuth 2 access token is just one long string.

    In your API v1 code, you're storing that via the access_token variable under DROPBOX_PREFS_SECRET.

    In your API v2 code, you're storing that via the access_token variable under DROPBOX_PREFS_TOKEN.

    (Part of the confusion may be that API v1 supported both OAuth 1 and OAuth 2. OAuth 1 access tokens are comprised of two pieces, a key and secret. API v2 only supports OAuth 2. OAuth 2 access tokens only have the one piece.)

Thanks Greg, sounds simple.  I was using OAuth2 and storing the token in SharedPrefs with API v1 (see below)

String access_token = session.getOAuth2AccessToken();
SharedPreferences prefs = getSharedPreferences(DROPBOX_PREFS, MODE_PRIVATE);
prefs.edit.putString(DROPBOX_PREFS_KEY, "oauth2:").commit();
prefs.edit.putString(DROPBOX_PREFS_SECRET, access_token).commit();

and in API v2 I'm using...

 

String access_token = Auth.getOAuth2Token();
SharedPreferences prefs = getSharedPreferences(DROPBOX_PREFS, MODE_PRIVATE);
prefs.edit().putString(DROPBOX_PREFS_TOKEN, access_token).apply();

So to get the token from API v1, I should be able to simply use the following .ine below?  Sorry I'm getting a bit confused - is the APIv1 "secret" the same as APIv2 "token"?

 

String api1_token = prefs.getString(DROPBOX_PREFS_SECRET, null);

 

Many thanks,

M.
