 * Set this to true to create two separate APKs instead of one:
 *   - An APK that only works on ARM devices
 *   - An APK that only works on x86 devices
 * The advantage is the size of the APK is reduced by about 4MB.
 * Upload all the APKs to the Play Store and people will download
 * the correct one based on the CPU architecture of their device.
def enableSeparateBuildPerCPUArchitecture = false

 * Run Proguard to shrink the Java bytecode in release builds.
def enableProguardInReleaseBuilds = false

 * The preferred build flavor of JavaScriptCore.
 * For example, to use the international variant, you can use:
 * `def jscFlavor = 'org.webkit:android-jsc-intl:+'`
 * The international variant includes ICU i18n library and necessary data
 * allowing to use e.g. `Date.toLocaleString` and `String.localeCompare` that
 * give correct results when using with locales other than en-US.  Note that
 * this variant is about 6MiB larger per architecture than default.
def jscFlavor = 'org.webkit:android-jsc:+'

 * Whether to enable the Hermes VM.
 * This should be set on project.ext.react and mirrored here.  If it is not set
 * on project.ext.react, JavaScript will not be compiled to Hermes Bytecode
 * and the benefits of using Hermes will therefore be sharply reduced.
