Using Hazelcast on Android gives random errors

Question

I'm trying to use Hazelcast on Android. I can include the dependency and the predefined "Hello World" will show up nicely without error. As soon as I put this code into my Activity (i.e. starting to use Hazelcast) it gives me an error:

Code:

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Config cfg = new Config();
        HazelcastInstance instance = Hazelcast.newHazelcastInstance(cfg);
    }

It can't seem to find some classes which are always working and are part of the Android Library. When I try to find the code I can find it. When I remove the instance creation of Hazelcast there is no problem either..

Anybody has an idea what this problem might be?

Thanks in advance!

The exception doesn't seem to be HZ related ' Caused by: java.lang.ClassNotFoundException: Didn't find class "android.view.View$OnUnhandledKeyEventListener" — pveentjer, Jun 21 '18 at 10:36

This is caused by an incompatibility with the android support library that changed to version 28.

I my case I solved the problem by changing from

implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'

to

implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'.

so try to use previous versions.

My project built successfully working after I changed this. Hope this might help you too.
