+ * 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
