/**
* 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.
*
* project.ext.react = [
* // the name of the generated asset file containing your JS bundle
* bundleAssetName: "index.android.bundle",
*
* // the entry file for bundle generation
* entryFile: "index.android.js",
*
* // whether to bundle JS and assets in debug mode
* bundleInDebug: false,
*
* // whether to bundle JS and assets in release mode
* bundleInRelease: true,
*
* // whether to bundle JS and assets in another build variant (if configured).
* // See http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Build-Variants
* // The configuration property can be in the following formats
* // 'bundleIn${productFlavor}${buildType}'
* // 'bundleIn${buildType}'
* // bundleInFreeDebug: true,
* // bundleInPaidRelease: true,
* // bundleInBeta: true,
*
* // whether to disable dev mode in custom build variants (by default only disabled in release)
* // for example: to disable dev mode in the staging build type (if configured)
* devDisabledInStaging: true,
* // The configuration property can be in the following formats
* // 'devDisabledIn${productFlavor}${buildType}'
* // 'devDisabledIn${buildType}'
*
* // the root of your project, i.e. where "package.json" lives
* root: "../../",
*
* // where to put the JS bundle asset in debug mode
* jsBundleDirDebug: "$buildDir/intermediates/assets/debug",
*
* // where to put the JS bundle asset in release mode
* jsBundleDirRelease: "$buildDir/intermediates/assets/release",

*
* // where to put drawable resources / React Native assets, e.g. the ones you use via
* // require('./image.png')), in release mode
* resourcesDirRelease: "$buildDir/intermediates/res/merged/release",
*
* // by default the gradle tasks are skipped if none of the JS files or assets change; this means
* // that we don't look at files in android/ or ios/ to determine whether the tasks are up to
* // date; if you have any other folders that you want to ignore for performance reasons (gradle
* // indexes the entire tree), add them here. Alternatively, if you have JS files in android/
* // for example, you might want to remove it from here.
