🚧: Support KVM Emulating

[WindSekirun]

== IN-PROGRESS ==

• Plugin Site: https://plugins.jenkins.io/android-emulator/
  • It seems to search environment variables follow ANDROID_SDK_ROOT / ANDROID_SDK_HOME / ANDROID_HOME / ANDROID_SDK
  • So, adding 'ANDROID_SDK_ROOT' into environment variables will not help to this problem

Test after setting up the development environment locally

• Showing [android] Outdated SDK Tools found. Upgrading from '26.1.1' to 'build 6609375' warning

  • Use newer version of SDK Tools, commandlinetools-linux-6609375_latest.zip
  • Sdkmanager should handle current state of Dockerfile, but it doesn't.
  • After some googling, I find work-around of this. https://stackoverflow.com/a/60454207
  • RUN echo yes | sdkmanager --sdk_root=${ANDROID_SDK_ROOT} "platform-tools" "build-tools;30.0.2"

• SDK_ROOT problem is gone, but emulator: ERROR: x86_64 emulation currently requires hardware acceleration! is came out

  • KVM is needed in emulate Android emulator in Linux
  • But, some host doesn't support kvm on there host
  • It seems that version separation is necessary.
