[移动开发]在gitlab上实现CI的配置文件（.gitlab-ci.yml）

内容：
记录了目前使用过的项目的一些配置; 其内主要是通过实现apk的打包来校验代码正确性。

• react-native:

before_script:
   - yarn

cache:
  untracked: true
  key: "$CI_PROJECT_ID"
  paths:
    - node_modules/
    - android/.gradle/

buildapk:
  stage: build
  script:
    - cd android
    - chmod +x ./gradlew
    - ./gradlew assembleRelease
  artifacts:
    paths:
      - android/app/build/outputs/apk/release/app.apk

• flutter

test:
  stage: test
  image: "cirrusci/flutter:stable"
  script:
    - cd flutter_project/example
    - flutter build apk
  artifacts:
    paths:
      - flutter_project/example/build/app/outputs/flutter-apk/app-release.apk
