Before publishing an Android application, it is imperative to utilize a code obfuscation tool, such as ProGuard, to prevent individuals from getting unhindered access to your source code by utilizing various means, such as decompilation. ProGuard is prepackaged included within the Android SDK, and, as such, no dependency inclusion is required. It is automatically included in the build process if you specify your build type to be a release. You can find out more about ProGuard here: https://www.guardsquare.com/en/proguard .
