    You mentioned this is for an Android app, but the DbxWebAuth you're using isn't meant for Android. The API v2 Java SDK does have specific support for Android though. There's an example Android app using it here.

     

    - To set that up, your AndroidManifest.xml should be set up as shown here.

    - You start the flow by calling startOAuth2Authentication as shown here.

    - You complete the flow by calling getOAuth2Token as shown here.

    - Your app can store and re-use the resulting access token for that user, as the example does here.

    - Once you have an access token, you can make a client as shown here.

     

    For the code you are currently using though, it looks like you're getting that 'invalid_access_token' error because you're supplying an authorization code, instead of an access token.

     

    When using DbxWebAuth, you get back an "authorization code", which is not an access token. You need to exchange that authorization code for an access token, as shown here.
