Hello Michael,

You are using a very old version of Android SDK. There have been a significant number of fixes and enhancements to the Android SDK since Android v3 Beta-02 SDK ( Jan 27, 2017) was released. We strongly recommend that you upgrade to the latest version of the Android SDK v3.0.3. It can be found at the following URL.

You will note that in the Android 3.0.0 Beta-05 release there was a fix made to correct a problem with checking that a username exists.

Please let us know once you have completed the upgrade.

Hi Billy,

Sorry, typos. We are using Android 3.0.1 SDK, but experiencing the same issue.


Can you please upgrade to the latest Android SDK v3.0.3? This might not fix the issue but we strongly recommend customers to use the latest version of the SDK.



Hi Michael,

I can confirm that you should be able to check the username exists with following code. I have tested it with the latest Kinvey sdk (v3.0.3) and it is working for me:

                         UserStore.exists("Username", MyKinveyClient, new KinveyClientCallback<Boolean>() {


                             public void onSuccess(Boolean aBoolean) {

                                 System.out.println(" If Username already Exist :"+aBoolean);



                             public void onFailure(Throwable throwable) {

                                 System.out.println(" something went wrong: "+throwable);



Please try this code and make sure you are using correct credentials for initialising your KinveyClient. The exception you are getting usually occurs because of the incorrect credentials. Please get back to us if the problem persists.
