How to stop folder access prompt appearing every time?

Question

Is it possible to configure or code my Android app so that the below prompt doesn't appear every single time I restart my app?

I only have the one API call below and yet I see the above prompt every single time I start my app.

Auth.startOAuth2Authentication( gContext, APP_KEY );

Surely there must be a way to code or configure an app so that this doesn't appear every single time?

I've solved this problem myself. I don't need to call the below line every startup:

Auth.startOAuth2Authentication( gContext, APP_KEY );

Once I get an access token, I can store that for subsequent program restarts and create a DbxClientV2 by using that saved token.

DbxRequestConfig config = new DbxRequestConfig( "dropbox/sample-app" );
DbxClientV2 client = new DbxClientV2( config, savedToken );

No more auth screen, yay!
