/**
* 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.

* // "index.android.js" exists, it will be used. Otherwise "index.js" is
* // default. Can be overridden with ENTRY_FILE environment variable.
