How to store image files from android app using mobile backend starter?

[Kevin Fan]

Hi,

I read we we use cloud storage with mobile backend starter by creating url

// get a secure URL for uploading a private file
URL url = blobEndpoint.getUploadUrl("receipts",  
                             getReceiptFileName(),"PRIVATE")
                       .execute().getShortLivedUrl());

but example is lacking.

Could you please provide a simple example of uploading a simple image file to cloud store using mobile backend starter?

Thank you.

The only mobile backend starter tutorial is located here: https://developers.google.com/cloud/samples/mbs/deploy_backend

But if you specifically want to experiment with the image upload capability, the best way would be to run both the mobile backend starter and the Android client. You can see the README files for the mobile backend starter and the Android client to understand how they're deployed.

Hi
I have already generated the client library and trying the get upload url like this:

try {
            BlobEndpoint blobEndpoint = new BlobEndpoint();
            String url = blobEndpoint.getUploadUrl("profileImages","images","PRIVATE").execute().getShortLivedUrl();
        } catch (IOException e) {
            e.printStackTrace();
        }

But its giving this error:
No enclosing instance of type Mobilebackend is accessible. Must qualify the allocation with an enclosing instance of type Mobilebackend (e.g. x.new A() where x is an instance of Mobilebackend).

Did you get this code snippet from http://googlecloudplatform.blogspot.com/2013/11/connecting-mobile-developers-to-the-cloud-with-google-cloud-endpoints.html ? If so, did you copy the original example endpoint code at https://github.com/GoogleCloudPlatform/solutions-mobile-backend-starter-java/blob/master/src/com/google/cloud/backend/spi/BlobEndpoint.java or did you write your own endpoint?
