We have recently made a few changes in the master branch that requires dependencies that only Android Studio 3.5 Preview/Beta able to provide. Are you using 3.5 already?

Alternatively our Android build would also work with Gradle wrapper on CLI or with the latest release of InteliJ IDEA.

thank you！ weitjong , i will try it again.
