[Android] Expansion file 이용하기 - 2

이전 포스트에서 간단하게 확장 파일을 저장해서 테스트 해보는 것 까지 작성 해보았다.

http://gogorchg.tistory.com/entry/Android-Expansion-file-%EC%9D%B4%EC%9A%A9%ED%95%98%EA%B8%B0-1

이번 포스트에선 직접 google play console에 APK와 확장 파일을 올려보고

앱을 설치하여 결과를 확인 하는 것 까지 해보겠다.

우선 확장 파일 다운로드를 위한 Service와 Receiver를 Sample에서 가지고 오겠습니다.

android-sdk/extras/google/market_apk_expansion/downloader_sample/src/com/example/expansion/downloader 에 있는

SampleAlarmReceiver.java 와 SampleDownloaderService.java 두 파일을 복사 해서 프로젝트에 붙여 넣습니다.

그런 후, 아래 형태로 소스를 만드세요.

## AndroidManifest.xml
