Hi @IvanKobzarev,
Please check the below build.gradle file content.I don’t have CMakeLists.txt.
apply plugin: “com.android.application”
import com.android.build.OutputFile
/**

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 debug mode
resourcesDirDebug: “$buildDir/intermediates/res/merged/debug”,


// 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.
inputExcludes: [“android/", "ios/”],


// override which node gets called and with what additional arguments
nodeExecutableAndArgs: [“node”],


// supply additional arguments to the packager
extraPackagerArgs: []
