안드로이드 50메가가 넘어가는 파일 다운로드
생각 없이 쭉 따라 하면 됩니다.
확장 파일은 안드로이드 콘솔에다 업로드 하는데 .. 누구는 압축을 안한 압축파일을 하라고해서 그렇게 하니 됐습니다.
알집에 보니 압축률 없이 압축하는 방법이 있습니다.
안드로이드에서 샘플이 제공되고 있습니다.
D:\adt-bundle-windows-x86_64\sdk\extras\google\play_apk_expansion\downloader_sample
파일이 저장되면 아래의 경로에 저장 됩니다.
Environment.getExternalStorageDirectory() + "/Android/obb/" + thePackageName + "/main."
+ Def.EXTENSION_FILE_VERSION + "." + thePackageName + ".obb";
시작합니다.
아래의 두개의 프로젝트를 import한다
D:\adt-bundle-windows-x86_64\sdk\extras\google\play_apk_expansion\downloader_library
D:\adt-bundle-windows-x86_64\sdk\extras\google\play_apk_expansion\zip_file
downloader_library여기서 에러 나는데 library라이센스를 다시 정해 주면된다
라이센스는 D:\adt-bundle-windows-x86_64\sdk\extras\google\play_licensing 여기 있습니다.
downloader_library,zip_file 둘을 작업 중인 프로젝트에서 프로젝트>안드로이드>library에 add한다

요건 파일 가져오는거 2가지 방법
public AssetFileDescriptor getAssetFileDescriptor(String filePath) {
PackageManager manager = this.getPackageManager();
PackageInfo info;
try {
info = manager.getPackageInfo(this.getPackageName(), 0);
} catch (NameNotFoundException e) {

return null;
}

// int thePackageVer = info.versionCode;
String zipFilePath = Environment.getExternalStorageDirectory() + "/Android/obb/" + thePackageName + "/main."
+ Def.EXTENSION_FILE_VERSION + "." + thePackageName + ".obb";
ZipResourceFile expansionFile = null;
AssetFileDescriptor afd = null;
try {
expansionFile = new ZipResourceFile(zipFilePath);
afd = expansionFile.getAssetFileDescriptor(filePath);
} catch (IOException e) {
e.printStackTrace();
}
return afd;
}
public InputStream getAssetFileInputStream(String filePath) {

try {

} catch (NameNotFoundException e) {

라이센스 에러 나고 페치 url 실패 나고 하는데요
확장 파일 버젼 잘 맞추고 사이닝된 apk파일과 콘솔에 올린 버젼이 같으면 됩니다.
일단은 저는 알파테스트로 apk를 올리고 거기다 확장 파일 올리고
다음 부터는 싸이닝된 apk파일 만들어서 폰에 넣고 설치하고를 반복 하면서 테스트 했습니다.
그런데 확장 파일콘솔에 올리고 난뒤에 디버깅으로 앱 설치해도 확장 파일 다운로드가 되네요 디버깅이 더 쉬워 졌어요
처음에 콘솔에 올리고 언제 업데이트 되서 테스트 하나 막막했음 ....
