Android with Google Cloud Storage got Invalid Credentials

Question

I want to use Google Storage from my android device. I enable google storage service and google storage json api. I enable the billing too.

I got my SHA1 fingerprint from the following command line :

keytool -list -v -keystore  ~/.android/debug.keystore 

I set the "SHA1 key;com.mydomain" in the api console and I got my Simple API.

I am trying to get the content of the bucket but I am stuck with the following error:

 com.google.api.client.googleapis.json.GoogleJsonResponseException: 401 Unauthorized
    {
    "code" : 401,
    "errors" : [ {
    "domain" : "global",
    "location" : "Authorization",
    "locationType" : "header",
    "message" : "Invalid Credentials",
    "reason" : "authError"
    } ],
    "message" : "Invalid Credentials"

    }

    private Storage getStorageService() {

    public void doImport() {

            if( account == null) {
                GoogleAccountManager googleAccountManager = new GoogleAccountManager(activity);
                Account[] accounts = googleAccountManager.getAccountManager().getAccountsByType(GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE);
                account = accounts[2];
            }


            new BucketTask().execute(account);

        } catch (Throwable t) {
            Log.e(TAG, "Error while trying to import images from server",  t);
        }
    }

    private Bucket getBucket() {

        Log.i("Getting bucket " + settings.getBucket() + " metadata");
        Bucket bucket = null;
        try {
            Storage.Buckets.Get getBucket = storage.buckets().get(settings.getBucket());
            getBucket.setPrettyPrint(true);
            bucket = getBucket.execute();
            Log.i(bucket.toPrettyString());
        } catch (UserRecoverableAuthIOException e) {
            activity.startActivityForResult(e.getIntent(), StartupActivity.REQUEST_AUTHORIZATION);
        } catch (IOException e) {

            try {

                    credential.setSelectedAccountName(account.name);
                }

                if( storage == null && credential != null) {
                    storage = getStorageService();
                }

            //Do something with result
            if (result != null)
                result.getId();
        }
    }
}

I followed the Drive sample.

Any advice ?

Answer 1

I found out the issue.

Don't use the Simple API Access coming from the API console but you have to setup the Client ID for installed applications (see the Drive SDK link above)

So instead of :

private Storage getStorageService() {

        StorageRequestInitializer storageRequestInitializer = new StorageRequestInitializer(ClientCredentials.API_KEY);

        return new Storage.Builder(transport,
                                    JSON_FACTORY,
                                    credential)
                                    .setApplicationName(APPLICATION_NAME)
                                    .setStorageRequestInitializer(storageRequestInitializer)
                                    .build();
    }

you should use it like this:

private Storage getStorageService() {

        return new Storage.Builder(transport,
                                    JSON_FACTORY,
                                    credential)
                                    .setApplicationName(APPLICATION_NAME)
                                    .build();
    }

Hope that help !
