What is the right technique to automate Android builds from command line with gradlew command?

[Prahlad Yeri]

I want to build my Android Studio project from command line as opening it consumes too much RAM. Besides, my app is "WebView heavy", most of the work happens in HTML/JS/CSS inside of the webview, so it makes sense to build the APK/AAB directly from command line for testing. So far, I'm able to generate bunlde with the below command after setting the JAVA_HOME to `\path\to\android-studio\jre\jre` gradlew bundle However, this generates only the bundle file (*.aab) and that too the unsigned or debug version. What I want to generate is: 1. Signed *.aab to release on Play Store. 2. Unsigned *.apk for testing. When I list the tasks using `gradlew tasks` command, it gives me the below. What should I do to achieve these objectives? I already tried some other tasks (build and assemble) as parameters but they result in error. **EDIT:** OK, found some helpful information [here](https://developer.android.com/build/building-cmdline). The second one (debug APK) I managed with the `assembleDebug` task. The first one (signing the aab) is still a constraint.
