Synchronous calls not working

[jzitkovic]

I have an issue with synchronous login when I call it from the main thread. I wanted to make my login synchronous because I use it in Rx chain and I don't want to have callbacks.

Response<ResponseZerokitLogin, ResponseZerokitError> r = Zerokit.getInstance().login(zerokitId, mPasswordET.getPasswordExporter(), true).execute();

Here is my log:

java.lang.IllegalStateException: Sync method call from the main thread is only possible after the initialization was finished.You can call sync method from background thread any time, or from main thread after the initialization is done. You can call async method from any looper thread any time

I have also tried to do initialize zerokit again with: Zerokit.getInstance().initMain(); but then I get ANR when I try to login.

Hi,
The Zerokit.getInstance().initMain(); is not enough, because this call only returns a Call instance, so you need to call enqueue(new Action<Void>() {...} on it, because it is an async call.
The initMain() can only be called async, but after it has finished, you can call sync methods from main thread also. (From background thread you can call sync methods any time without the init restriction)

[jzitkovic]

Yes, of course I have done that:

Zerokit.getInstance().initMain().enqueue(new Action<Void>() {
                    @Override
                    public void call(Void aVoid) {...}
                });

I have tested other methods like getIdentityTokens(String clientId).execute() synchronous and it worked.
But synchronous login Zerokit.getInstance().login(zerokitId, PasswordET.getPasswordExporter(), true).execute() method is not working. I always get ANR or this message: Sync method call from the main thread is only possible after the initialization was finished. You can call sync method from background thread any time, or from main thread after the initialization is done. You can call async method from any looper thread any time.
