System Info

1. react-native: 0.59.8
2. android-studio: 3.3.1

Background

I'm making simple react-native app. I tried to upload my application on Google Play Store, but failed. I followed this documentation. As it said, I typed ./gradlew buildRelease on terminal. It results below.

> Configure project :react-native-voice
WARNING: Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'.
It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html
WARNING: Configuration 'testCompile' is obsolete and has been replaced with 'testImplementation'.
It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html
WARNING: The specified Android SDK Build Tools version (23.0.2) is ignored, as it is below the minimum supported version (28.0.3) for Android Gradle Plugin 3.3.1.
Android SDK Build Tools 28.0.3 will be used.
To suppress this warning, remove "buildToolsVersion '23.0.2'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.

Problem

Yes, it show BUILD SUCCESSFULL in 29s! but there is no android/app/build/outputs/bundle/release/app.aab or in any folder.
