Risky Change

This is considered a risky change because it adjusts the sample app build.gradle, please review carefully.
We've seen issues in the past which resulted in failed builds for merchants. Please make sure the build.gradle change is intended.

By adding the label accept-risky-change to this PR, I acknowledge that I'm changing an example app and have verified that the SDK remains in a shippable state.

Re-doing this pull request here, as this one’s notify risk change check seems corrupted somehow.
