[zeromq-dev] Zyre on Android (JNI)

[Arnaud Loonstra]

I have hardly any experience either but I asked a colleague.

We just created a simple app with

     zyre = new Zyre("android_test");
     zyre.start();

in the constructor and

     zyre.stop()

in the destructor.

The lib you provided is 64bit so it doesn't work on a 32bit device :(
