Hi Orhan Abi,

Espresso is waiting for AsyncTask on network calls. Is it possible to do it on Wasp? There is same problem on Retrofit link below.

Retrofit can do it.
The most straightforward solution for this: is to basically swap out Retrofit's Thread-pool executor with an AsyncTask one.

new RestAdapter.Builder()
.setEndpoint(LOCLSET_SERVER_URL)
.setExecutors(AsyncTask.THREAD_POOL_EXECUTOR,
new MainThreadExecutor())
.build();
