I am trying to use Retrofit+RxJava as http client in iOS, so I can keep compatibility with other android app, and dex2oat task always fails.
Execution failed for task ‘:digicash_ios_project:moeMainDebugX86Dex2Oat’.
Process ‘command ‘/Applications/Intel/multi_os_engine/tools/dex2oat’’ finished with non-zero exit value 134
I am not sure how to proceed or debug this, I am still too fresh with multi OS, is this library incompatibility? My libs are JAVA-only (I believe), heres my gradle dependency:
Thank you for your fast reply, here is full error log:

I cannot provide any code now, ill setup a github example with it asap if this log doesn’t help.
Looks like the problem comes from Retrofit library.
Also ProGuard will trim out some classes which retrofit requires. Please add a proguard.append.cfg file to your MOE module with the following contents:
The project compiles with that dependencies you mentioned, do you mind explaining me how did you find that these two were missing? So perhaps I can find it next time I thought everything was included in initial retrofit compile.
It works great, amazing!
Other question:
Ex:
RestClient.instance.getRandomTrivia()
.subscribe(new Observer() { @Override
public void onCompleted() {
}
@Override
public void onError(Throwable e) {
}
@Override
public void onNext(TriviaResponse triviaResponse) {
statusText.setText(text);
}
});
How do I set text to an UI label inside an observer callback?
statusText.setText(text); --> not working, I assume it is not being called in UI thread or something?
Explanation would not be so simple, but we already have plans for improving error messages for situations like this. However when you see this message Pending exception java.lang.NoClassDefFoundError: Class not found using the boot class loader; no stack trace available it mostly comes down to searching for missing classes, most likely from dependencies (sometimes from dependencies marked as optional).
This messages gives a good starting point: Unexpected failure to resolve a method: void retrofit.client.ApacheClient$GenericEntityHttpRequest.(retrofit.client.Request). You need to dig into the source code of this method and look for dependencies your IDE cannot correctly resolve, those are the dependencies you are most likely missing.
Regarding ReactiveX, we have a port and a sample project here.
thank you
