Invalid access token
I generated an access token while creating my project on dropbox app console, and used that token to let my user's to fetch data from my drobox using my android app, everything worked fine for months...
I got the information while generating the access token that i should use standard auth process to generate access tokens for my users. What does that mean then
This is sample code which iam using to make my user a client through access token.. am i making some mistake which can cause to my access token invalid?
public class Main { private static final String ACCESS_TOKEN = "<ACCESS TOKEN>"; public static void main(String args[]) throws DbxException { // Create Dropbox client DbxRequestConfig config = DbxRequestConfig.newBuilder("dropbox/java-tutorial").build(); DbxClientV2 client = new DbxClientV2(config, ACCESS_TOKEN); }
FullAccount account = client.users().getCurrentAccount();
ListFolderResult result = client.files().listFolder(""); while (true) { for (Metadata metadata : result.getEntries()) { System.out.println(metadata.getPathLower()); } if (!result.getHasMore()) { break; } result = client.files().listFolderContinue(result.getCursor()); }

No, there's nothing in this code that would invalidate the access token.
Please refer to my earlier comment for a list of things that can disable an access token.
- I have read them all and i didnot use any code which could lead my user to invalidate access token, my app was working fine for 10 months without any trouble but this month i have got two times invalid token exceptions and i do not know what could cause it, i have to update my app with new token each time

While you yourself may not have revoked the token, it's possible someone who downloaded your app did. Since you embedded your access token in the app, someone could extract it from the app and then use /2/auth/token/revoke (or any other API endpoint) themselves. This is one of the reasons we don't recommend distributing your own access token like this.
