Hello I've downloaded and installed the latest version of Drive REST API for java and want to get the metadata of a public file from Google Drive by the fileID - I have the following code:
private static final String APPLICATION_NAME = "test";
private static final String FILE_ID = "theFileId";
public static void main(String[] args) {
HttpTransport httpTransport = new NetHttpTransport();
JacksonFactory jsonFactory = new JacksonFactory();
Drive service = new Drive.Builder(httpTransport, jsonFactory, null).setApplicationName(APPLICATION_NAME).build();
printFile(service, FILE_ID);
}
private static void printFile(Drive service, String fileId) {
try {
File file = service.files().get(fileId).execute();
System.out.println("Title: " + file.getTitle());
} catch (IOException e) {
System.out.println("An error occured: " + e);
}
}
But I get the error message: "Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."
I've tried it on https://developers.google.com/drive/v2/reference/files/get which worked out just fine.
Do I have to authenticate with an API key when the file is public and how would I do that if so.
Thanks for your time.
Yes, you need to authenticate with an API key. See the documentation here: https://developers.google.com/drive/web/about-auth

I'm working on some improvement on our google drive integration.
Current state:
There is already implementation of saving files into Google Drive folders using hard-coded folderId. This works with no problems.
Now: I want to extend this logic and I need for this list of all folders.
So I followed this guide:
https://developers.google.com/drive/api/guides/search-files
And the problem is that I receive only **one** folder but in google drive there is 10.
Can anyone has any idea what I missed or overlooked? Why result doesn't contain nextPageToken? Spent whole day on it and this drives me crazy.
This is my method (i'm using service account for connection):
#Override
public List<File> getAllFolders() throws IOException {
Drive service = googleDriveProvider.getService();
List<File> files = new ArrayList<>();
String pageToken = null;
do {
FileList result = service.files().list()
.setQ("mimeType='application/vnd.google-apps.folder'")
.setSpaces("drive")
.setSupportsAllDrives(true)
.setIncludeItemsFromAllDrives(true)
.setFields("nextPageToken, files(id, name, parents)")
.setPageToken(pageToken)
.execute();
for (File file : result.getFiles()) {
System.out.printf("Found file: %s (%s)\n",
file.getName(), file.getId());
}
files.addAll(result.getFiles());
pageToken = result.getNextPageToken();
} while (pageToken != null);
return files;
}
And this is GoogleDriveProvider:
#Service
public class GoogleDriveProvider {
private static final JsonFactory JSON_FACTORY = GsonFactory.getDefaultInstance();
private static final Set<String> SCOPES = DriveScopes.all();
private static final String GET_DRIVE_SERVICE_ERROR_MESSAGE = "Getting instance of Google drive has failed, error: [%s]";
#Value("${google.drive.service.account.auth.json}")
private String authJson;
#Value("${info.app.name}")
private String appName;
public Drive getService() throws GoogleDriveException {
try {
final NetHttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
GoogleCredentials credentials = GoogleCredentials.fromStream(
new ByteArrayInputStream(authJson.getBytes())).createScoped(SCOPES);
credentials.refreshIfExpired();
HttpRequestInitializer requestInitializer = new HttpCredentialsAdapter(credentials);
return new Drive.Builder(httpTransport, JSON_FACTORY, requestInitializer)
.setApplicationName(appName)
.build();
} catch (IOException | GeneralSecurityException e) {
throw new GoogleDriveException(
format(GET_DRIVE_SERVICE_ERROR_MESSAGE, e.getMessage()), e);
}
}
}
Problem solved. Folders must be created by the service account or must be shared with service account first.
I making an app using google drive to store files for user to their google drive
I followed google developer guide in https://developers.google.com/drive/api/guides/about-sdk
and when i press the button to upload my files i got the err in title
this is
my code :
try {
// Load pre-authorized user credentials from the environment.
GoogleCredentials credentials = GoogleCredentials.getApplicationDefault()
.createScoped(Arrays.asList(DriveScopes.DRIVE_FILE));
HttpRequestInitializer requestInitializer = new HttpCredentialsAdapter(
credentials);
Drive service = new com.google.api.services.drive.Drive.Builder(new NetHttpTransport(),
GsonFactory.getDefaultInstance(),
requestInitializer)
.setApplicationName(getString(R.string.app_name))
.build();
File fileMetaDate = new File();
fileMetaDate.setName(getString(R.string.db_name_lists));
File file1 = service.files().create(fileMetaDate, fileContent)
.setFields("id")
.execute();
Toast.makeText(this, file1.getId() + " has been created", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
e.printStackTrace();
}
error
The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise - java android
To use
GoogleCredentials credentials = GoogleCredentials.getApplicationDefault()
You must have the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials.
Other wise you can do it like shown in the Google drive java quickstart
private static final String CREDENTIALS_FILE_PATH = "/credentials.json";
InputStream in = DriveQuickstart.class.getResourceAsStream(CREDENTIALS_FILE_PATH);
if (in == null) {
throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
}
GoogleClientSecrets clientSecrets =
GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
I am trying to learn the usage of Google Analytics API. I am following the tutorial provided by "https://developers.google.com/analytics/devguides/config/mgmt/v3/quickstart/service-java" and have copy pasted their code.
I have used the following dependency:
<groupId>com.google.apis</groupId>
<artifactId>google-api-services-analytics</artifactId>
<version>v3-rev20190807-1.32.1</version>
But I am facing three problems:
Cannot resolve method 'initializeAnalytics' in 'HelloAnalytics'
Cannot resolve symbol 'AnalyticsReporting'
Incompatible types. Found: 'com.google.api.services.analytics.Analytics', required: 'AnalyticsReporting'
The problems are bring faced in following areas:
private static AnalyticsReporting initializeAnalytic() throws GeneralSecurityException, IOException {
HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();
GoogleCredential credential = GoogleCredential
.fromStream(new FileInputStream(KEY_FILE_LOCATION))
.createScoped(AnalyticsScopes.all());
// Construct the Analytics service object.
return new Analytics.Builder(httpTransport, JSON_FACTORY, credential)
.setApplicationName(APPLICATION_NAME).build();
}
and
public static void main(String[] args) {
try {
Analytics analytics = initializeAnalytics();
String profile = getFirstProfileId(analytics);
System.out.println("First Profile Id: "+ profile);
printResults(getResults(analytics, profile));
} catch (Exception e) {
e.printStackTrace();
}
}
Kindly let me know if I am making any mistake or if there is any solution available.
I'm trying to save a file to Google App Engine and following their documentation, but constantly getting the NullPointerException on the CreateOrReplace method line. Already figured it out that gcsService is created. Any ideas?
public String getFileUrl(MultipartFile file) throws CustomException {
String unique = UUID.randomUUID().toString();
String fileName = unique + ".jpeg";
GcsFilename gcsFilename = new GcsFilename("MY_BUCKET", fileName);
try {
GcsOutputChannel outputChannel = GcsServiceFactory.createGcsService().createOrReplace(gcsFilename, GcsFileOptions.getDefaultInstance());
copy(file.getInputStream(), Channels.newOutputStream(outputChannel));
} catch (IOException e) {
e.printStackTrace();
}
ImagesService imagesService = ImagesServiceFactory.getImagesService();
ServingUrlOptions options = ServingUrlOptions.Builder
.withGoogleStorageFileName("/gs/MY_BUCKET/" + fileName)
.secureUrl(true);
return imagesService.getServingUrl(options);
}
Included dependency:
<dependency>
<groupId>com.google.appengine.tools</groupId>
<artifactId>appengine-gcs-client</artifactId>
<version>0.7</version>
</dependency>
And getting the:
RetryHelper(32.34 s, 6 attempts, com.google.appengine.tools.cloudstorage.GcsServiceImpl$1#74c3f0b0): Too many failures, giving up
With the exception in the log:
c.g.a.tools.cloudstorage.RetryHelper : RetryHelper(1.386 s, x attempts, com.google.appengine.tools.cloudstorage.GcsServiceImpl$1#6bd1dbe9): Attempt #x failed [java.io.IOException: java.lang.NullPointerException], sleeping for x ms
Thanks in advance!
Edit:
Found that ApiProxy class in com.google.apphosting.api on
public static ApiProxy.Delegate getDelegate() {
return delegate;
}
returns NULL.
Any ideas?
I am trying to implement Watson API for visual recognition. I encounter the following error message:
Here is the code:
public class VisualRecognizer {
private VisualRecognition service;
public VisualRecognizer() {
this.service = new VisualRecognition(VisualRecognition.VERSION_DATE_2016_05_20);
this.service.setApiKey("ourkey");
this.service.setEndPoint("https://gateway-a.watsonplatform.net/visual-recognition/api");
}
public String classifyImage(String filePath) throws FileNotFoundException {
InputStream imageStream = new FileInputStream(filePath);
ClassifyOptions classifyOptions = new ClassifyOptions.Builder()
.imagesFile(imageStream)
.build();
ClassifiedImages result = service.classify(classifyOptions).execute();
Any suggestions on how to solve this would be greatly appreciated.
Please mention a file name.
ClassifyOptions classifyOptions = new ClassifyOptions.Builder()
.imagesFile(imageStream).imagesFilename("xyz.jpg")
.build();
For me it worked
