Auth redirect url

[eyra]

Why does the redirect url after the Authorization process look like "#access_token=IuAX.........".

The # at the start prevents my server code from getting the url parameters. Using

.request().queryString()

in java

That's the OAuth 2 "token" flow, where the access token is returned on the redirect URI fragment. That's meant more for client-side apps. For server-side apps, you should use the "code" flow. You can find more information here:

How would a native mobile client get access to this value?

[Greg-DB]

@david48 Exactly how this works will depend on your particular scenario. For instance, for a locally running native mobile client, it can use a custom local URL scheme in its redirect URI. The app would register for that local URL scheme, so the redirect would be sent directly to the app (i.e., not a remote web server), where the app can parse the token from the fragment of the URL.

We recommend using one of the official SDKs, if possible, as they do most of the work for you:

Hello,

Auth.startOAuth2Authentication(this, "55556756765765756");

@schrettinger in your startOAuth2Authentication function are you providing the correct app key taken from your App Console? The example you provided with "55556756765765756" does not seem to be a valid app key format.

[schrettinger]

Hello,

thanks for your answer.

I'm using the correct app-key. DropBox recommends the real app-key not to public.

After

Auth.startOAuth2Authentication(this, "4534hkzhxc8hj" - is not the real app-key) 

the redirect Url

db-4534erter45646://1/connect?oauth_token=oauth2:&oauth_token_secret=sl.BE4JfDiYMLV2GSkHe-f-TkpxD1-n0EcIIqBbPhQGH5ACISVsMB_AUznLC1weqvQWqsgQEAMgiWQmtXmbGZQ4Wfg2QvbBl1qVImRkJECSWV8sbxharzhk50b9jUfbOsPF_VseA9wgj45R&uid=422345066&state=oauth2%3Ae803b8143706e7ecd2603b2213e1c5a7&expires_in=14400

I tried to generate an Access Token with

private void getAccessToken() {
String accessToken = Auth.getOAuth2Token();
if (accessToken != null) {
SharedPreferences prefs = getSharedPreferences(App_User.userName, Context.MODE_PRIVATE);
prefs.edit().putString("access-token", accessToken).apply();}
} 

The return is always null, because the redirect URL (s. above) to the app from DropBox is not valid.

Hello,

no answer helped me. Nobody told me what's the reason for the invalid URL.

@schrettinger I understand you're attempting to integrate with the Dropbox API in your Android app. To do so, please make sure you're following the instructions here exactly:

https://github.com/dropbox/dropbox-sdk-java/tree/master/examples/DropboxAndroid

That will guide you through using the right methods and setting your app key correctly.
