We’ve been using the Android Zoom SDK v5.10.1.5184 for our native Android app, and yesterday when JCenter went down, we decided to change out jcenter() for mavenCentral().
One of the dependencies used in the Zoom SDK in :mobilertc's build.gradledependencies.add("default","com.google.android:flexbox:2.0.1") does not exist on mavenCentral.
I am not aware of any plans to update this dependency to a version hosted on Maven Central. That being said, JCenter is still planned to stay alive indefinitely as a read-only repository. We cannot guarantee that it won’t have any outages as we do not own JCenter, but it should still be possible to download this artifact from that repository under normal circumstances.
Since this dependency is used by the Zoom Meeting SDK, I would not recommend using a different version. The SDK is built and tested with the version used in the sample app, so we cannot make any guarantees that the SDK will work correctly if you integrate mismatched versions in your project.
