ActivityNotFoundException: Unable to find explicit activity class {com.example.prod/com.zipow.videobox.JoinByURLActivity};  
getting this error while integrating android SDK in application.

SDK initializes properly.

Found one solution on devforum for this issue i.e. set compile version 29 but it does not work for me.

Also tried with cleaning the project and rebuilding it.  
Also done with reintegrating it.

I am sharing my build.gradle fine

**build.gradle(module:app)**

```
apply plugin: 'com.android.application'

    mavenCentral()

    }
    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
    buildTypes {
        debug {

Hi @ehiddenbrain,

Thanks for the post. We have followed the configurations you have here with our demo app and we did not encounter any issues. Would you mind providing a demo apk that has this issue for us to further investigate this issue?

Thanks!
