无法使用Google Downloader Sample下载APK扩展

Question

I am trying to get the Downloader Sample to download APK expansion files running. I have carefully gone through the instructions from Google docs on APK Expansion Files and also the very detailed intructions here Steps to create APK expansion file

I've

• Changed the sample code to include my BASE64_PUBLIC_KEY
• Uploaded the APK and expansion file to Google Play, and saved the application
• Changed the source code of the sample to reflect the file's size in bytes

Still, when I run the sample on my device I get the message

Download failed because the resources could not be found

Any help would be greatly appreciated.

Answer 1

它突然工作了，我的猜测是原因是对上载的应用程序所做的更改需要时间才能传播。

Answer 2

(Sorry.. this is Question) Can we use this Dowloader sample in our App? If used, is there any license related requirements? because every SDK samples are shipped with apache license 2.0
