Uploading image from Android to GCS

阅读更多关于 Uploading image from Android to GCS

I am trying to upload an image from Android directly to Google cloud storage. But the API does not seem to work. They have some Java samples which are tied to the App engine. I don't see any sample which is proven to work on Android. On Android, I tried using the json api to upload an image. I am able to upload an image object but it seems to be corrupt. Moreover generating the authentication token seems to be tricky too. I am struck with this right now. Did anyone on this earth ever tried uploading an image/video from Android using Java client or Json API and succeeded? Can someone point me

To access Google APIs we store username and password in configuration file, which is a security risk and customer does not like that. So we would like to use OAuth2 long-living access token instead. what`s default expiration time for Google OAuth2 access tokens ? As we will have only access token in application, app itself cannot refresh it when access token expires...
