-Because We need to allow 64-bit machines to run Android's 32-bit tools, so we need to execute:
-```shell
-- apt-get --quiet install --yes wget tar unzip lib32stdc++6 lib32z1

-This command needs to be executed in amd64 architecture machine,
-so we should config the runner both size and arch tag below at `.gitlab-ci.yml` to ensure the architecture is right to execute.

-default:
-  image: openjdk:8-jdk
-  tags:
-    - size:2xlarge
-    - arch:amd64
