That's the way all APK files are built and that's how legacy hybrid apps are assembled. There's nothing wrong with the build system, all APK files are ZIP files that you can open. You can minify and obfuscate the code before you submit it for build to minimize the ability to inspect the source. IPA packages for iOS have the same characteristic, as do APPX files for Windows. This is standard practice.
