Change the Host File of an Android Emulator

A step-by-step guide for editing the hosts file on an Android emulator to support local development with custom subdomains. Covers setting up an Android Studio AVD using an older non-Google API Android 7.1.1 x86_64 image (required for root access), launching the emulator with the -writable-system flag, using adb commands to pull the hosts file, mapping the host machine's IP (10.0.2.2) to a custom domain, and pushing the modified hosts file back to the emulator.
