I see errors in logcat, what do they mean?

org.infobip.mobile.messaging.api.support.ApiException: UNAUTHORIZED, Invalid login details If you see this error in logs, then device will never register in the system. This error means that invalid Application Code was provided to the library. Check that valid code is set in strings.xml or via MobileMessaging.Builder#withApplicationCode, MobileMessaging.Builder#withApplicationCodeProvider.

org.infobip.mobile.messaging.mobile.InternalSdkError$InternalSdkException: SDK_ERROR, 20006, There is no valid registration This error is printed to logcat log when device is not yet registered in the system. Under normal circumstances this error should disappear once registration is created.
