Answer 1

In onCreate() write

AppKeyPair pair = new AppKeyPair(ACCESS_KEY, ACCESS_SECRET);
    session = new AndroidAuthSession(pair, AccessType.APP_FOLDER);
    dropbox = new DropboxAPI(session);

    SharedPreferences prefs = getSharedPreferences(DROPBOX_NAME, 0);
    String key = prefs.getString(ACCESS_KEY, null);
    String secret = prefs.getString(ACCESS_SECRET, null);
    if (key != null && secret != null) {
        Log.d("key secret", key + "    " + secret);
        AccessTokenPair token = new AccessTokenPair(key, secret);
        dropbox.getSession().setAccessTokenPair(token);
    }
    if (key == null && secret == null)
            dropbox.getSession().startAuthentication(DropboxActivity.this);

And in onResume() write

if (dropbox.getSession().isLinked()) {
        try {
            loggedIn(true);
            doAction();
        } catch (IllegalStateException e) {
            Toast.makeText(this, "Error during Dropbox authentication",
            Toast.LENGTH_SHORT).show();
        }

        } else if (dropbox.getSession().authenticationSuccessful()) {
            try {
                session.finishAuthentication();
                TokenPair tokens = session.getAccessTokenPair();
                SharedPreferences prefs = getSharedPreferences(DROPBOX_NAME, 0);
                Editor editor = prefs.edit();
                editor.putString(ACCESS_KEY, tokens.key);
                editor.putString(ACCESS_SECRET, tokens.secret);
                editor.commit();

                loggedIn(true);
                doAction();

            } catch (IllegalStateException e) {
                Toast.makeText(this, "Error during Dropbox authentication",
                        Toast.LENGTH_SHORT).show();
            }

        }

It worked fine for me
