## Description We use the flavors into our apps to use different version. We have dev, test and prod. When we have upgraded to 0.63, to classpath("com.android.tools.build:gradle:3.5.3") and distributionUrl=https\://services.gradle.org/distributions/gradle-6.2-all.zip, we cannot use the appbundle. when we run ./gradlew bundleDevRelease -> we cannot find into the app-dev-release.aab the index.android.bundle. This cause a crash when open the app. If we run this command : ./gradlew bundleRelease -> it build all variants app-dev-release.aab -> missing app-test-release.aab -> index.android.bundle present app-prod-release.aab -> index.android.bundle present it seems that the first time not set the index.android.bundle into assets ## React Native version: System: OS: macOS 10.15.2 CPU: (4) x64 Intel(R) Core(TM) i5-7360U CPU @ 2.30GHz Memory: 382.96 MB / 16.00 GB Shell: 5.7.1 - /bin/zsh Binaries: Node: 11.10.0 - /usr/local/bin/node Yarn: 1.13.0 - /usr/local/bin/yarn npm: 6.7.0 - /usr/local/bin/npm Watchman: 4.9.0 - /usr/local/bin/watchman Managers: CocoaPods: 1.9.2 - /usr/local/bin/pod SDKs: iOS SDK: Platforms: iOS 13.2, DriverKit 19.0, macOS 10.15, tvOS 13.2, watchOS 6.1 Android SDK: API Levels: 23, 27, 28, 29 Build Tools: 26.0.2, 27.0.3, 28.0.3, 29.0.2 System Images: android-19 | Google APIs Intel x86 Atom, android-23 | Google APIs Intel x86 Atom_64, android-27 | Intel x86 Atom_64, android-28 | Google APIs Intel x86 Atom Android NDK: Not Found IDEs: Android Studio: 4.0 AI-193.6911.18.40.6514223 Xcode: 11.3/11C29 - /usr/bin/xcodebuild Languages: Java: 1.8.0_201 - /usr/bin/javac Python: 2.7.16 - /usr/bin/python npmPackages: @react-native-community/cli: Not Found react: 16.13.1 => 16.13.1 react-native: 0.63.0 => 0.63.0 npmGlobalPackages: *react-native*: Not Found ## Steps To Reproduce 1.Create a new project: npx react-native init AppName --template react-native-template-typescript 2. Add to gradle.build : productFlavors { prod { } dev { applicationId 'com.appname.dev' resValue "string", "build_config_package", "com.appname" } test { applicationId 'com.appname.test' resValue "string", "build_config_package", "com.appname" } } 3. run into android folder : ./gradlew clean && ./gradlew bundleDevRelease ## Expected Results Obtain an .aab file into android/build/outputs/bundle/devRelease. when i open the .aab i expect to find the folder base and into the base the folder assets that contain the index.android.bundle.
