  1. Do you use our Android library in your app?
  2. Can you login with the same account in REST Console (see here for an example)

No, i used rest api because my min sdk is 19 and min sdk for android library is 21; as you see in response Login done successful because i get back user-token, but in my app i failed because response not match with our Model i set to response; but i do not know where is the problem exactly: in my model, in response, in schema of table?

my problem solved. Model had a property with int type but response had same property with String type, so model could not match with response and i got this error, thank you.
