Hi @ada We solved the problem. we copied the proguard-rules.pro file from the sample app and it worked.  
add this to the packaging options in your gradle build:

```auto
packagingOptions {
    ...
    pickFirst '**/*.so'
}

```

add these to your proguard rules:

```auto

-keep class us.zoom**{
   *;
}
-keep interface us.zoom**{
   *;
}

-keep class org.webrtc**{
   *;
}

-keep class com.zipow**{
   *;
}

```

this fixed the initialization crash for me.  
good luck!
