Java SDK - No refresh token?
Hey,
i try to get the refresh token with the Java SDK (Android App).
I start authentication with this:
Auth.startOAuth2Authentication(getContext(), "abc");
And then in onResume:
@Override
public void onResume() {
super.onResume();
if (_isCloudAuthFlow) {
_isCloudAuthFlow = false;
String token = Auth.getOAuth2Token();
String refresh = Auth.getDbxCredential().getRefreshToken();
_businessLogic.getSharedPreferences().edit().putString(getString(R.string.all_settings_dropbox_authtoken), token).apply();
}
}
I get a authToken but the refresh token is always null.
Can you help?
The startOAuth2Authentication method uses the old flow, which currently gives legacy "long-lived access tokens", which don't expire by themselves. Note that starting September 30th, 2021 Dropbox will no longer return new long-lived access tokens, so you should switch to the new flow.
The startOAuth2PKCE uses the new flow, which gives "short-lived access tokens", which do expire by themselves, as well as "refresh tokens", which don't expire by themselves.

You should use the startOAuth2PKCE method instead of startOAuth2Authentication now. You can find an example here:

Yes, with the startOAuth2PKCE - Method i get a refresh token. Does the authToken with startOAuth2Authentication - Method never expire?
