app cresh when click on chat button.

The application functions properly, but when attempting to initiate a chat by clicking on the chat button, the application crashes immediately. I attempted to diagnose the issue using Android Studio, and it generated the following error.

it looks like it is the issue of proguard, but i don't enabled the proguard in my application. i am using the following configuration

"dependencies": { "jsrsasign": "^10.9.0", "jsrsasign-util": "^1.0.5", "react": "18.2.0", "react-native": "0.72.4", "react-native-zoom-us": "^6.19.4" },

Please let me know if any suggestion.
Thanks in advance.

I am also experiencing the crash. @mieszko4 The app is crashing with the following error:

java.lang.NoClassDefFoundError: Failed resolution of: Lio/reactivex/disposables/CompositeDisposable;
                                                                                                    	at us.zoom.zmsg.fragment.MMChatInputFragment.<init>(MMChatInputFragment.java:224)
                                                                                                    	at us.zoom.proguard.l83.<init>(ZmMeetingChatInputFragment.java:1)
                                                                                                    	at us.zoom.proguard.p93.<init>(ZmMeetingNormalChatInputFragment.java:1)

I'm am currently stuck on trying to fix it. Any ideas? I don't think it's a proguard issue.

Hi @wilkinson4,

I have successfully identified the root cause of the issue. It appears that a crucial library, namely 'reactivex', is absent. To rectify this, kindly include the following dependency in the node_modules\react-native-zoom-us\android\build.gradle -> dependencies :

implementation 'io.reactivex.rxjava2:rxjava:2.1.13'

Thanks

That did it! PR is up. Thank you!
