invaild access token? what's problem? When you run into here in the access token 403, and returns the invalid access token. You will know what is the problem? plz help me. my application ===================== private final String[] APP_SCOPES = {"profile"}; public AmazonAuthorizationManager getAmazonAuthorizationManager() { if (amazonAuthorizationManager == null) amazonAuthorizationManager = new AmazonAuthorizationManager(getApplicationContext(), Bundle.EMPTY);
