/**

The react.gradle file registers a task for each build variant (e.g. bundleDebugJsAndAssets
and bundleReleaseJsAndAssets).
These basically call react-native bundle with the correct arguments during the Android build
cycle. By default, bundleDebugJsAndAssets is skipped, as in debug/dev mode we prefer to load the
bundle directly from the development server. Below you can see all the possible configurations
and their defaults. If you decide to add a configuration block, make sure to add it before the
apply from: "../../node_modules/react-native/react.gradle" line.
