Android Question Dropbox v2 auth flow

[Gavins]

Hi DonManfred,

Sorry to trouble you. I'm having some issues with the authorisation flow using the v7 SDK.

Where as previously I could call auth.startOAuth2Authentication and all was right with the world, I'm having issues getting auth.startOAuth2PKCE to work.

is auth.startOAuth2PKCE(requestConfig as com.dropbox.core.DbxRequestConfig) correct?

There's a note to see Auth#startOAuth2PKCE(Context, String, DbxRequestConfig, DbxHost) in the XML but I can't find this to call?

If I call it as it is I get a an error:

java.lang.NoClassDefFoundError: Failed resolution of: Lkotlin/jvm/internal/Intrinsics;
at com.dropbox.core.android.Auth$Companion.startOAuth2PKCE(Unknown Source:2)
at com.dropbox.core.android.Auth.startOAuth2PKCE(Unknown Source:2)
etc.

Any guidance when you have time would be appreciated.

Many thanks
Gavin

There are two ways of authentification.

Both of them works. Thought startOAuth2PKCE is probably the most interestin one. If i remember correctly it works only if the official Dropbox-App is installed on the Device.
Using this method you get all the informations needed to do a token-refresh if it expires. Without userinteraction needed.

The other one is generating a Auth-URL and open a webbrowser for the user to accept the connection. You´ll get a token back in the webview which you need to copy manually and finalize the authflow in your app then using the copied token. The user need to be involved copying the token, pasting it in your app. This one should work even if there is no Dropboxapp installed on the Device.

I´ll post an Example soon showing both Techniques.

Thanks, I'll look forward the example.

Seems like it got more complicated with v7.

Seems like it got more complicated with v7.

Once you have startOAuth2PKCE working you´ll not miss it anymore cause of its simplicity.
