I try to copy one file from one folder to other folder inside the same bucket. For copying the file i use CopyObjectRequest class. But i do not know how can i get the progress of copy operation?
So please help me in it , how can i get the progress status of copy operation.
For copy operation i followed this way-
try {
AmazonS3 s3Client =new AmazonS3Client(credentials,cc);
// Copy the object into a new object in the same bucket.
CopyObjectRequest copyObjRequest = new CopyObjectRequest(bucketName, sourceKey, "wedorias-new", "test/test111/logo.png"/*destinationKey*/);
s3Client.copyObject(copyObjRequest);
if (copyObjRequest.isRequesterPays()){
System.out.println("sadfbgnh==");
}
} catch (AmazonServiceException e) {
// The call was transmitted successfully, but Amazon S3 couldn't process
// it, so it returned an error response.
e.printStackTrace();
System.out.println("exception==!"+e.getErrorMessage());
System.out.println("exception==!"+e.getErrorCode());
System.out.println("exception==!"+e.getMessage());
} catch (Exception e) {
e.printStackTrace();
System.out.println("exception==!"+e.getMessage());
}
If you want to copy one object from one folder to another one (Or other Buckets if it's the case) and check the progress, you will have to use Amazon S3 Multipart Upload.
AWS docs have a nice example called Copy an Object Using the AWS SDK for Java Multipart Upload API, it shows you what you have to do to set it up and check the progress of the copy.
// Get the object size to track the end of the copy operation.
GetObjectMetadataRequest metadataRequest = new GetObjectMetadataRequest(sourceBucketName, sourceObjectKey);
ObjectMetadata metadataResult = s3Client.getObjectMetadata(metadataRequest);
long objectSize = metadataResult.getContentLength();
Notice
Multipart upload is a must when the object is greater than 5GB.
Multipart upload is recommended when the object is greater than 100MB.
Multipart upload doesn't work if the object is less than 5MB.
How to create File from Imageurl?
I know How to
Download Image from Url using AsyncTask
I want to know about how can I create File object without download Image from url.
I tried like below.
File file = new File("http://www.planwallpaper.com/static/images/Winter-Tiger-Wild-Cat-Images.jpg");
I want to use this file in status.setMedia(file)
StatusUpdate status = new StatusUpdate(twitterMessage);
status.setMedia(file );
try {
twitter4j.Status response = twitter.updateStatus(status);
return response.toString();
} catch (TwitterException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
But no success.
Please help me about create File direct from imageurl without download Image.
How to create File from Imageurl?
You don't. File is for local files. A URL is for something that is stored on a server, and particularly in this case, that server is not the device itself, and so the URL does not point to a local file... unless you download a copy of that content to a local file.
I want to use this file in status.setMedia(file)
See if that API offers other parameter types than File, like Uri, that the library would use to support network-based sources of the media. If not, you have no choice but to download the data and provide a File pointing to your local copy.
you means show the image with a default image,but not really download.
then,when click on it,download it.right?
you can request JSON info from server then store the ImagerUrls into a list.when the user click the imageView ,then you can take out the ImagerUrl and download the image with volley or AsyncTask.
I am using android-demos for implementing Google Drive integration in android. I successfully created a file in google drive. Now i want to delete that newly created file. I found the reference for this through https://developers.google.com/drive/v2/reference/files/delete Now files() method in this link is not found in Drive.
private static void deleteFile(Drive service, String fileId) {
try {
service.files().delete(fileId).execute();
} catch (IOException e) {
System.out.println("An error occurred: " + e);
}
}
Now please tell me how to delete file from Google Drive. I did research on this but found no solution. Some says use previous api of Google Drive. But that is obsolete now. Now Goole uses V2 for Drive.
Last time I checked, there is no delete in GDAA. See How to delete a file on google drive using Google Drive Android API
You can either wait for it to be implemented, or use the REST API https://developers.google.com/drive/v2/reference/files/delete
I suspect you are confusing two different APIs. GDAA is a purely local API, ie. your app is communicating with the Android Drive app. With the REST API, your app is talking over http to the Google Drive servers. Your app can use either, or a mixture of both (although you need to be pretty desparate to do that).
Deleting files from Google drive using core API is not yet supported. So you must use Restful API calls. To do restful API calls you need to add following jars to your lib folder
google-api-client-1.19.1.jar
google-api-client-android-1.19.1.jar
google-api-services-drive-v2-rev158-1.19.1.jar
google-http-client-1.19.0.jar
google-http-client-android-1.19.0.jar
google-http-client-gson-1.19.0.jar
google-oauth-client-1.19.0.jar
gson-2.1.jar
jsr305-1.3.9.jar
now you can do restful API call withing core API calls as follows
com.google.api.client.googleapis.extensions.android.gms.auth.GoogleAccountCredential crd = GoogleAccountCredential
.usingOAuth2(
ctx,
Arrays.asList(com.google.api.services.drive.DriveScopes.DRIVE_FILE));
crd.setSelectedAccountName(email);
_drvSvc = new com.google.api.services.drive.Drive.Builder(
AndroidHttp.newCompatibleTransport(), new GsonFactory(), crd).setApplicationName("SmsAndCallLogBackup")
.build();
remember i connected to Google drive using core API. and for deleting only I am using restful API
following method is used to delete file from Google drive
public void delete(DriveId dId) {
try {
String fileID = dId.getResourceId();
if (fileID != null)
_drvSvc.files().delete(fileID).execute();
} catch (Exception e) {
e.printStackTrace();
}
}
call this method in async task otherwise it gives error
it will work definitely
I have done it successfull
**
private GoogleApiClient api;
**
public void Update(DriveId dId) {
try {
DriveFile sumFile = dId.asDriveFile();
com.google.android.gms.common.api.Status deleteStatus =
sumFile.delete(api).await();
if (!deleteStatus.isSuccess()) {
Log.e(TAG, "Unable to delete app data.");
} else {
// Remove stored DriveId.
preferences_driverId.edit().remove("drive_id").apply();
}
} catch (Exception e) {
e.printStackTrace();
}
}
I am working on integrating Apache FTP server to my Android app.
Follow the instructions here ( Embedding FtpServer in 5 minutes): http://mina.apache.org/ftpserver-project/embedding_ftpserver.html.
However, with all the codes included and the jar files imported to my android project, I got two major errors:
1. App crash upon ftp server start claiming class not found
2. Dalvik error 1
Tried every method by researching all related problems and the solution is to keep the minimal subset of the jar files that are listed in the (Embedding FtpServer in 5 minutes) instruction and make the code compile. Since there are not many jar files so I just did some try and error to get my minimal subset.
After that I use some new code to start the ftp server(here is the link): writing a java ftp server
However I couldn't connect because it says missing user.properties file. I download ftpserver-1.0.6-src source code and put the user.properties file into my android sdcard to make the ftp start. I put the user.properties file in the assets folder first, then copy it to the sdcard by using some code.
Now everything seems to work. However, I am not able to use anonymous login as my user name and password is set using:
BaseUser user = new BaseUser();
user.setName("test");
user.setPassword("test");
If I don't set it, the code won't compile.
Log in as anonymous user is the last part I have to do.
Another trivial thing is when I ftp to my android server, it won't allow me to download the files as it returns no permission error.
Any suggestions are welcome. Thank you
I've have had the same problem, so I've created my custom new users.properties file.
Here it is the code:
File files=new File(filepath + "/users.properties");
if (!files.exists()) {
try {
files.createNewFile();
} catch (IOException e) {
Log.e(TAG, "Errore nella creazione del file di log", e);
e.printStackTrace();
}
}
userManagerFactory.setFile(files);
userManagerFactory.setPasswordEncryptor(new SaltedPasswordEncryptor());
UserManager um = userManagerFactory.createUserManager();
BaseUser user = new BaseUser();
user.setName("xxx");
user.setPassword("yyy");
user.setHomeDirectory("/mnt/sdcard");
List<Authority> auths = new ArrayList<Authority>();
Authority auth = new WritePermission();
auths.add(auth);
user.setAuthorities(auths);
try {
um.save(user);
} catch (FtpException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
I've spent the last six hours pouring over documents from Google and I still don't know how to get started with this. All I want to do is make it so my existing Android app can read files from Google Drive, upload new files to Google Drive, and edit existing files on Google Drive.
I've read that Drive SDK v2 was focused solely on making it easy for Android (and mobile in general) developers to use it, and yet there seems to be virtually nothing in their documentation about it.
Ideally, I'd like someone to point at some decent documentation, example, or tutorial covering how to do this (keep in mind I'm using Android. They have plenty of stuff on how to use Drive with the Google App Engine; I have already looked at it and I have no idea how to go from that to an Android app.)
I need to know which libraries I need to download and add to my project, what I need to add to my manifest, and how I can ultimately get a list of files from Google Drive, download one, and then upload a modified version.
Ideally, I'd like it to handle accounts automatically, the way that the officially Google Drive app does.
Edit: Claudio Cherubino says that Google Play Services is now available and will make this process a lot easier. However, there's no sample code available (yet, he says it's coming soon... they said Google Play Services was "coming soon" 4 months ago, so there's a good chance this answer will continue to be the only completely working example of accessing Google Drive from your Android application into 2013.)
Edit 2X: Looks like I was off by about a month when I said Google wouldn't have a working example until next year. The official guide from Google is over here:
https://developers.google.com/drive/quickstart-android
I haven't tested their methods yet, so it's possible that my solutions from September 2012 (below) are still the best:
Google Play Services is NOT REQUIRED for this. It's a pain in the butt, and I spent well over 50 hours (edit: 100+ hours) figuring it all out, but here's a lot of things that it'll help to know:
THE LIBRARIES
For Google's online services in general you'll need these libraries in your project: (Instructions and Download Link)
google-api-client-1.11.0-beta.jar
google-api-client-android-1.11.0-beta.jar
google-http-client-1.11.0-beta.jar
google-http-client-android-1.11.0-beta.jar
google-http-client-jackson-1.11.0-beta.jar
google-oauth-client-1.11.0-beta.jar
guava-11.0.1.jar
jackson-core-asl-1.9.9.jar
jsr305-1.3.9.jar
For Google Drive in particular you'll also need this:
google-api-services-drive-v2-rev9-1.8.0-beta.jar (Download Link)
SETTING UP THE CONSOLE
Next, go to Google Console. Make a new project. Under Services, you'll need to turn on two things: DRIVE API and DRIVE SDK! They are separate, one does not automatically turn the other on, and YOU MUST TURN BOTH ON! (Figuring this out wasted at least 20 hours of my time alone.)
Still on the console, go to API Access. Create a client, make it an Android app. Give it your bundle ID. I don't think the fingerprints thing is actually important, as I'm pretty sure I used the wrong one, but try to get that right anyways (Google provides instructions for it.)
It'll generate a Client ID. You're going to need that. Hold onto it.
Edit: I've been told that I'm mistaken and that you only need to turn on Drive API, Drive SDK doesn't need to be turned on at all, and that you just need to use the Simple API Key, not set up something for Android. I'm looking into that right now and will probably edit this answer in a few minutes if i figure it out...
THE ANDROID CODE - Set Up and Uploading
First, get an auth token:
AccountManager am = AccountManager.get(activity);
am.getAuthToken(am.getAccounts())[0],
"oauth2:" + DriveScopes.DRIVE,
new Bundle(),
true,
new OnTokenAcquired(),
null);
Next, OnTokenAcquired() needs to be set up something like this:
private class OnTokenAcquired implements AccountManagerCallback<Bundle> {
#Override
public void run(AccountManagerFuture<Bundle> result) {
try {
final String token = result.getResult().getString(AccountManager.KEY_AUTHTOKEN);
HttpTransport httpTransport = new NetHttpTransport();
JacksonFactory jsonFactory = new JacksonFactory();
Drive.Builder b = new Drive.Builder(httpTransport, jsonFactory, null);
b.setJsonHttpRequestInitializer(new JsonHttpRequestInitializer() {
#Override
public void initialize(JSonHttpRequest request) throws IOException {
DriveRequest driveRequest = (DriveRequest) request;
driveRequest.setPrettyPrint(true);
driveRequest.setKey(CLIENT ID YOU GOT WHEN SETTING UP THE CONSOLE BEFORE YOU STARTED CODING)
driveRequest.setOauthToken(token);
}
});
final Drive drive = b.build();
final com.google.api.services.drive.model.File body = new com.google.api.services.drive.model.File();
body.setTitle("My Test File");
body.setDescription("A Test File");
body.setMimeType("text/plain");
final FileContent mediaContent = new FileContent("text/plain", an ordinary java.io.File you'd like to upload. Make it using a FileWriter or something, that's really outside the scope of this answer.)
new Thread(new Runnable() {
public void run() {
try {
com.google.api.services.drive.model.File file = drive.files().insert(body, mediaContent).execute();
alreadyTriedAgain = false; // Global boolean to make sure you don't repeatedly try too many times when the server is down or your code is faulty... they'll block requests until the next day if you make 10 bad requests, I found.
} catch (IOException e) {
if (!alreadyTriedAgain) {
alreadyTriedAgain = true;
AccountManager am = AccountManager.get(activity);
am.invalidateAuthToken(am.getAccounts()[0].type, null); // Requires the permissions MANAGE_ACCOUNTS & USE_CREDENTIALS in the Manifest
am.getAuthToken (same as before...)
} else {
// Give up. Crash or log an error or whatever you want.
}
}
}
}).start();
Intent launch = (Intent)result.getResult().get(AccountManager.KEY_INTENT);
if (launch != null) {
startActivityForResult(launch, 3025);
return; // Not sure why... I wrote it here for some reason. Might not actually be necessary.
}
} catch (OperationCanceledException e) {
// Handle it...
} catch (AuthenticatorException e) {
// Handle it...
} catch (IOException e) {
// Handle it...
}
}
}
THE ANDROID CODE - Downloading
private java.io.File downloadGFileToJFolder(Drive drive, String token, File gFile, java.io.File jFolder) throws IOException {
if (gFile.getDownloadUrl() != null && gFile.getDownloadUrl().length() > 0 ) {
if (jFolder == null) {
jFolder = Environment.getExternalStorageDirectory();
jFolder.mkdirs();
}
try {
HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet(gFile.getDownloadUrl());
get.setHeader("Authorization", "Bearer " + token);
HttpResponse response = client.execute(get);
InputStream inputStream = response.getEntity().getContent();
jFolder.mkdirs();
java.io.File jFile = new java.io.File(jFolder.getAbsolutePath() + "/" + getGFileName(gFile)); // getGFileName() is my own method... it just grabs originalFilename if it exists or title if it doesn't.
FileOutputStream fileStream = new FileOutputStream(jFile);
byte buffer[] = new byte[1024];
int length;
while ((length=inputStream.read(buffer))>0) {
fileStream.write(buffer, 0, length);
}
fileStream.close();
inputStream.close();
return jFile;
} catch (IOException e) {
// Handle IOExceptions here...
return null;
}
} else {
// Handle the case where the file on Google Drive has no length here.
return null;
}
}
One last thing... if that intent gets sent off, you'll need to handle when it returns with a result.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 3025) {
switch (resultCode) {
case RESULT_OK:
AccountManager am = AccountManager.get(activity);
am.getAuthToken(Same as the other two times... it should work this time though, because now the user is actually logged in.)
break;
case RESULT_CANCELED:
// This probably means the user refused to log in. Explain to them why they need to log in.
break;
default:
// This isn't expected... maybe just log whatever code was returned.
break;
}
} else {
// Your application has other intents that it fires off besides the one for Drive's log in if it ever reaches this spot. Handle it here however you'd like.
}
}
THE ANDROID CODE - Updating
Two quick notes on updating the last modified date of a file on Google Drive:
You must provide a fully initialized DateTime. If you do not, you'll get a response of "Bad Request" from Google Drive.
You must use both setModifiedDate() on the File from Google Drive and setSetModifiedDate(true) on the update request itself. (Fun name, huh? "setSet[...]", there's no way people could mistype that one...)
Here's some brief sample code showing how to do an update, including updating the file time:
public void updateGFileFromJFile(Drive drive, File gFile, java.io.File jFile) throws IOException {
FileContent gContent = new FileContent("text/csv", jFile);
gFile.setModifiedDate(new DateTime(false, jFile.lastModified(), 0));
gFile = drive.files().update(gFile.getId(), gFile, gContent).setSetModifiedDate(true).execute();
}
THE MANIFEST
You'll need the following permissions: GET_ACCOUNTS, USE_CREDENTIALS, MANAGE_ACCOUNTS, INTERNET, and there's a good chance you'll need WRITE_EXTERNAL_STORAGE as well, depending on where you'd like to store the local copies of your files.
YOUR BUILD TARGET
Right click your project, go into it's properties, and under Android change the build target to Google APIs if you must. If they aren't there, download them from the android download manager.
If you're testing on an emulator, make sure its target is Google APIs, not generic Android.
You'll need a Google Account set up on your test device. The code as written will automatically use the first Google Account it finds (that's what the [0] is.) IDK if you need to have downloaded the Google Drive app for this to have worked. I was using API Level 15, I don't know how far back this code will work.
THE REST
The above should get you started and hopefully you can figure your way out from there... honestly, this is just about as far as I've gotten so far. I hope this helps A LOT of people and saves them A LOT of time. I'm fairly certain I've just written the most comprehensive set up guide to setting up an Android app to use Google Drive. Shame on Google for spreading the necessary material across at least 6 different pages that don't link to each other at all.
It's 2015, things have changed!
Get the 'Drive API for Android' with gradle:
compile 'com.google.android.gms:play-services-drive:7.8.0'
There's some new doco (although still lackluster IMO):
https://developers.google.com/drive/web/quickstart/android
And for those about to go caving...the biggest problem I encountered thus far is that there is absolutely no way of distinguishing folders that have been permanently deleted from folders that are normal...you can find them, you can create folders and files within them, only writing to the file DriveContents will always fail.
Check this video from Google I/O to learn how to integrate your Android app with Drive:
http://www.youtube.com/watch?v=xRGyzqD-vRg
Please be aware that what you see in the video is based on Google Play Services:
https://developers.google.com/android/google-play-services/
Take a look at Google's DrEdit Example, which has a folder called android/. Copy it, follow the readme, and it should work (works for me on an Android emulator with KitKat).
.
P.S.
Sorry for reviving this, but the new Google Drive Android API doesn't support full Drive access, only drive.file and drive.appdata authorization scopes, so if you need full access you have to go back to the good 'ol Google API's Client for Java (which the DrEdit example uses).
