How can we check that Google Tag manager works

Question

I am developing an android application, and I used google tag manager to collect data. When I run the project, the project work correctly and I have this in the console

V/GoogleTagManager﹕ Attempting to load a container from the resource ID 2131099648 (testconverteo.ismail.converteotag:raw/container_test)
V/GoogleTagManager﹕ The container was successfully loaded from the resource (using JSON file format)
V/GoogleTagManager﹕ Deleted 0 expired items
V/GoogleTagManager﹕ Attempting to load resource from disk

D/GoogleTagManager﹕ Setting previous container version: Nw$0

V/GoogleTagManager﹕ PowerSaveMode initiated.
V/GoogleTagManager﹕ PowerSaveMode terminated.
V/GoogleTagManager﹕ Dispatch running...
V/GoogleTagManager﹕ sent 1 of 1 hits

It seems that data are sent, but I have nothing in the interface of google analytics.
