Strange synchronization error while update (native Android)

Hi friends,

Yesterday update works fine, but today it throws some strange error. I can catch it and update is delivered in SAP and application continue to work but what causing this error? Deivce's protocol version is incompatible with the server's protocol version. (4 > 0) ???
