How to upload a file to GoogleDrive in android

I refer from this code
AccountManager am = AccountManager.get(activity);
am.getAuthToken(am.getAccounts())[0],
"oauth2:" + DriveScopes.DRIVE,
new Bundle(),
true,
new OnTokenAcquired(),
null);
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...
}
}
}
In jsonHttpRequestInitializer i get an issues. [GoogleClient$Builder cannot be resolved. It is indirectly referenced from required .class files] please suggest me what i have to do...

You have two different APIs you can use on Android, the REST and the GDAA.
REST is the 'barebones' API that gives you the full functionality of Google Drive. You also have an interactive playground to test everything (see the bottom of this page). But you have to manage the network delays, failures, etc... yourself. Ideally you would delegate that work to sync adapter service.
GDAA is built on top of REST, resides in Google Play Services and behaves as a local API with delayed promotion of objects (folders/files) to the Drive. Has only limited functionality compared to REST (forget thumbnail link, etc...). Essentially, you talk to GDAA and GDAA talks to the Drive on it's own schedule. So, you don't have to worry about on-line / off-line situations. Be careful though, this may also cause synchronization issues, since you don't have direct control over object promotion timing. The demos for GDAA can be found here and here.
I've also created a simple CRUD demo app that you can step through. The upload you're asking resides in create() method there. It is not fully up-to-date, since GDAA has implemented the 'trash' functionality already (in Google Play Services 7.00 / Rev. 23).
Good Luck

Create GoogleCredential by Access Token

I want to design an Android file viewer for Google Drive.
At first, I implemented the app by using of the Google Android API, as follows,
private void retrieveNextPage(){
if(mHasMore == false)
return;
Query query = new Query.Builder().setPageToken(mNextPageToken).build();
com.google.android.gms.drive.Drive.DriveApi.query(getGoogleApiClient(), query).setResultCallback(metadataBufferResultResultCallback);
}
However, the Android Drive API only allows the app to view and fetch the files that created by itself. I cannot access other files on the drive through the app.
Therefore, I turned to another option, directly manipulate the Java Drive API.
According to the example on developer guide for Java,
https://developers.google.com/drive/web/quickstart/quickstart-java
The users have to manually copy and paste the "Authorization Code" between the browser and app, which is not a practical way to acquire the Access Token in Android.
To come out a new way, I used the GoogleAuthUtil in Android API to acquire the Access Token, coincided with the GoogleCredential and Drive in Java API to fetch the file list, as follows,
private static List<File> retrieveFiles(Drive service) throws IOException{
List<File> result = new ArrayList<File>();
Files.List request = service.files().list();
do {
try{
FileList fileList = request.execute();
result.addAll(fileList.getItems());
request.setPageToken(fileList.getNextPageToken());
}catch (IOException e){
Log.d(dbgT + "JavaRetrieveFiles", "Retrieved Failed");
request.setPageToken(null);
}
}while (request.getPageToken() != null && request.getPageToken().length() > 0);
return result;
}
private class RetrieveTokenTask extends AsyncTask<String, Void, String>{
#Override
protected String doInBackground(String... params){
String accountName = params[0];
String scopes = "oauth2:" + "https://www.googleapis.com/auth/drive";
String token = null;
try{
token = GoogleAuthUtil.getToken(getApplicationContext(), accountName, scopes);
}
catch (IOException e){
Log.e(excpTAG, "IO Exception: " + e.getMessage());
}
catch (UserRecoverableAuthException e){
startActivityForResult(e.getIntent(), REQ_SIGN_IN_REQUIRED);
}
catch (GoogleAuthException e)
{
Log.e(excpTAG, "GoogleAuthException: " + e.getMessage());
}
return token;
}
#Override
protected void onPostExecute(String s){
super.onPostExecute(s);
//Get Access Token
Log.d( dbgT + "Token", s);
EditText tokenText = (EditText) findViewById(R.id.tokenText);
tokenText.setText(s);
EditText fileNameText = (EditText) findViewById(R.id.editTextMeta);
GoogleCredential credential = new GoogleCredential().setAccessToken(s);
HttpTransport httpTransport = new NetHttpTransport();
JsonFactory jsonFactory = new JacksonFactory();
Drive service = new Drive.Builder(httpTransport, jsonFactory, null).setHttpRequestInitializer(credential).build();
List<File> fileList;
try{
fileList = retrieveFiles(service);
for(int i=0; i< fileList.size(); i++)
fileNameText.append(fileList.get(i).getTitle());
}catch(IOException e){
Log.d(dbgT + "RetrieveFileList", "IO Exception" );
}
}
}
Unfortunately, the app always crashes by the causing of NetworkOnMainThreadException when request.execute() in retrieveFiles is invoked.
I checked my access token s, it is usually in form of ya29.xxx...etc., and it can also be passed to my other .NET program for retrieving files from Google Drive. Therefore I can certain the access token is correct.
So my question is, how to create a correct GoogleCredential by using of access token, instead of applying authorization code in setFromTokenResponse ?
Thanks in advance.

Many thanks for Andy's tips, this problem is simply caused by the network operations occurs on the main thread, which is a very basic newbie error.
The Drive in Google Drive SDK for Java, using network libraries without any background/thread worker, and now it is functional after I put the retrieveFiles() into background.
Applying the GoogleAuthUtil in Google Play Android SDK to acquire the access token, and followed by GoogleCredential+Drive in Java SDK that use the token to do the file operation in Google Drive.
This is a right way to avoid the scope restriction in Android SDK for Google Drive, allowing the developers to acquire the full permissive of accessing Google Drive.

facebook integration in android , post photos from all accounts

i have added facebook to my android app to share images and now the thing is that sharing can be done only from my facebook account, whenever i try and login from another account i cannot post any image this is the code snippet that i use . any help is appreciated
`
Request uploadRequest = Request.newUploadPhotoRequest(
Session.getActiveSession(), bmp, new Request.Callback() {
#Override
public void onCompleted(Response response) {
Toast.makeText(FacebookUpload.this,
"Photo uploaded successfully",
Toast.LENGTH_LONG).show();
`
there is a part lyk this
`public void postImage() {
if (checkPermissions()) {
Bitmap bmp = null;
String filename = getIntent().getStringExtra("image");
try {
FileInputStream is = this.openFileInput(filename);
bmp = BitmapFactory.decodeStream(is);
is.close();
} catch (Exception e) {
e.printStackTrace();
}
Request uploadRequest = Request.newUploadPhotoRequest(
Session.getActiveSession(), bmp, new Request.Callback() {
#Override
public void onCompleted(Response response) {
Toast.makeText(FacebookUpload.this,
"Photo uploaded successfully",
Toast.LENGTH_LONG).show();
File dir = getFilesDir();
File file = new File(dir, "bitmap.png");
file.delete();
}
});
// post on user's wall.
Bundle params =uploadRequest.getParameters();
Random rand = new Random();
int rndInt = rand.nextInt(3)+1;
if(rndInt==1)
params.putString("name", "download Chummi-Lalli Mobile App from https://play.google.com/store/apps/details?id=com.interactive8.readmestories");
else if(rndInt==2)
params.putString("name","Send gifts to your loved ones from www.ekhudol.com");
else if(rndInt==3)
params.putString("name","Chummilalli brought to you by www.3leafsolutions.co.in");
else
params.putString("name","Chummilalli brought to you by www.3leafsolutions.co.in");
uploadRequest.setParameters(params);
uploadRequest.executeAsync();
}
else
requestPermissions();
}`
n whenever i use another account i my code always goes to this else part requestPermission(), why am i redirected here always, everything works fine when i use my own facebook account

it was really simple, i had to do nothing but just submit my app to fb, i didnt know about this step on the developer website, i figured it out and now my app works just fine, thanks though

Drive SDK for Android AuthIntent is null

I'm trying to integrate Google Drive into my Android app so that I can store files in a user's Drive. I've enabled both Drive SDK and Drive API in the App Console and set up my Oauth 2 ClientIDs with my SHA1 fingerprint. As far as I can tell, everything looks good on Google's end.
Here's the code that initializes my Drive object.
private boolean initializeService(String accountName) {
if(service != null) {
return true;
}
GoogleAccountCredential credential = GoogleAccountCredential.usingOAuth2(mContext, DriveScopes.DRIVE);
mAuthIntent = null;
if(accountName != null) {
try {
credential.setSelectedAccountName(accountName);
Log.d("DriveHelper", credential.getToken());
service = getDriveService(credential);
} catch(Exception ex) {
if(ex instanceof UserRecoverableAuthException) {
UserRecoverableAuthException authException = (UserRecoverableAuthException)ex;
mAuthIntent = authException.getIntent();
mErrorCode = CloudHelper.CONNECTION_AUTHENTICATE;
((Activity)mContext).startActivityForResult(mAuthIntent, REQUEST_AUTHORIZATION);
} else {
Log.e("DriveCloudHelper", "Error retrieving auth token", ex);
}
return false;
}
getAppFolder();
return mFileLocation != null;
}
Activity activity = (Activity)mContext;
activity.startActivityForResult(credential.newChooseAccountIntent(), REQUEST_ACCOUNT_PICKER);
return false;
}
private Drive getDriveService(GoogleAccountCredential credential) {
return new Drive.Builder(AndroidHttp.newCompatibleTransport(), new GsonFactory(), credential)
.setApplicationName("Drive Helper")
.build();
}
These methods are called on a background thread and work just fine, the Account Picker appears, the Authorization window appears, all good. My getAppFolder method looks for a specific folder and creates it if not present without any issue (on the same background thread).
However, when I go to upload a file to Drive, the first operation I try on a new background thread causes a UserRecoverableAuthException, but a new exception occurs when I call getIntent because there's no Intent provided, and the detail message is AppDownloadRequired.
Here's the method that's generating the exception.
private String getIdFromFolder(String location, String name, boolean create) {
try {
String maskedName = name.replaceAll("/", "");
String query = "title contains '" + maskedName + "' and '" + location + "' in parents";
FileList list = service.files().list().setMaxResults(1).setQ(query).execute();
List<File> files = list.getItems();
if (files.isEmpty()) {
return create ? createSubFolder(location, name) : null;
}
return files.get(0).getId();
} catch (IOException e) {
// Eat the exception here
Log.w("DriveCloudHelper", e);
}
return create ? createSubFolder(location, name) : null;
}
And here's the stacktrace:

Try using mContext.getApplicationContext() in your GoogleAccountCredential.usingOAuth2 call rather than mContext as that seems to have fixed similar issues elsewhere.

Google Calendar API OAuth2 Troubles on Android Honeycomb

I am working on an Android Honeycomb (v3.0) application that has a requirement of communicating with the Google Calendar API. I would like to allow my application to access a particular Google account's Calendar data in order to read and create events.
Unfortunately, I ran into a problem with authorization using OAuth2. Here's what I have so far:
1) The Google account whose calendar I would like to access is registered within the Android device I am working with.
2) I enabled the Calendar API within the Google APIs Console on the account.
3) I am able to access this account using the following code:
AccountManager accountManager = AccountManager.get(this.getBaseContext());
Account[] accounts = accountManager.getAccountsByType("com.google");
Account acc = accounts[0]; // The device only has one account on it
4) I would now like to obtain an AuthToken for use when communicating with the calendar. I followed this tutorial, but converted everything to work with Google Calendar instead of Google Tasks. I successfully retrieve an authToken from the AccountManager with the account I would like to use by using getAuthToken with AUTH_TOKEN_TYPE == "oauth2:https://www.googleapis.com/auth/calendar".
5) Here's where the problems begin. I am now at this point:
AccessProtectedResource accessProtectedResource = new GoogleAccessProtectedResource(tokens[0]); // this is the correct token
HttpTransport transport = AndroidHttp.newCompatibleTransport();
Calendar service = Calendar.builder(transport, new JacksonFactory())
.setApplicationName("My Application's Name")
.setHttpRequestInitializer(accessProtectedResource)
.build();
service.setKey("myCalendarSimpleAPIAccessKey"); // This is deprecated???
Events events = service.events().list("primary").execute(); // Causes an exception!
6) Here's the exception returned by the last line:
com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden
{
"code" : 403,
"errors" : [ {
"domain" : "usageLimits",
"message" : "Daily Limit Exceeded. Please sign up",
"reason" : "dailyLimitExceededUnreg",
"extendedHelp" : "https://code.google.com/apis/console"
} ],
"message" : "Daily Limit Exceeded. Please sign up"
}
7) According to this Google API Video (wait a minute or so to get to the applicable content), a reason for this exception may be the fact that I did not enable the API access within the Google APIs Console for the account. However, if you look at 2), you can see that I did do so.
8) To me, it seems that the problem is that I was unable to set the Simple API Access Key correctly, because the Calendar.setKey method is deprecated. Within the Google Tasks tutorial that I previously linked, the key is set using Tasks.accessKey = "key". I'm not sure how to get this working with the Calendar API, though. I have tried multiple Google accounts, which all came up with the exception from 5).
9) I would like to point out that the traditional method of using OAuth2 did work for me. Here's the code I used for that:
HttpTransport TRANSPORT = new NetHttpTransport();
JsonFactory JSON_FACTORY = new JacksonFactory();
String SCOPE = "https://www.googleapis.com/auth/calendar";
String CALLBACK_URL = "urn:ietf:wg:oauth:2.0:oob";
String CLIENT_ID = "myClientID";
String CLIENT_SECRET = "myClientSecret";
String authorizeUrl = new GoogleAuthorizationRequestUrl(CLIENT_ID, CALLBACK_URL, SCOPE).build();
String authorizationCode = "???"; // At this point, I have to manually go to the authorizeUrl and grab the authorization code from there to paste it in here while in debug mode
GoogleAuthorizationCodeGrant authRequest = new GoogleAuthorizationCodeGrant(TRANSPORT, JSON_FACTORY, CLIENT_ID, CLIENT_SECRET, authorizationCode, CALLBACK_URL);
authRequest.useBasicAuthorization = false;
AccessTokenResponse authResponse = authRequest.execute();
String accessToken = authResponse.accessToken; // gets the correct token
GoogleAccessProtectedResource access = new GoogleAccessProtectedResource(accessToken, TRANSPORT, JSON_FACTORY, CLIENT_ID, CLIENT_SECRET, authResponse.refreshToken);
HttpRequestFactory rf = TRANSPORT.createRequestFactory(access);
AccessProtectedResource accessProtectedResource = new GoogleAccessProtectedResource(accessToken);
HttpTransport transport = AndroidHttp.newCompatibleTransport();
Calendar service = Calendar.builder(transport, new JacksonFactory())
.setApplicationName("My Application's Name")
.setHttpRequestInitializer(accessProtectedResource)
.build();
Events events = service.events().list("primary").execute(); // this works!
10) Finally, my question: I would like to use the account from the AccountManager on the device itself in order to retrieve a working OAuth2 token for use with the Google Calendar API. The second method is not useful for me, because the user will have to manually go to their web browser and get the authorization code, which is not user friendly. Anyone have any ideas? Apologies for the long post, and thanks!

Try adding a JsonHttpRequestInitializer to the builder and setting your key there:
Calendar service = Calendar.builder(transport, new JacksonFactory())
.setApplicationName("My Application's Name")
.setHttpRequestInitializer(accessProtectedResource)
.setJsonHttpRequestInitializer(new JsonHttpRequestInitializer() {
public void initialize(JsonHttpRequest request) {
CalendarRequest calRequest = (CalendarRequest) request;
calRequest.setKey("myCalendarSimpleAPIAccessKey");
}
}).build();

To answer no 10 : I've basically had to do what you had to do working with the TaskSample and then use the Android GData Calendar Sample available here : http://code.google.com/p/google-api-java-client/source/browse/calendar-android-sample/src/main/java/com/google/api/client/sample/calendar/android/CalendarSample.java?repo=samples
to get the AuthToken from the AccountManager itself:
accountManager = new GoogleAccountManager(this);
settings = this.getSharedPreferences(PREF, 0);
gotAccount();
private void gotAccount() {
Account account = accountManager.getAccountByName(accountName);
if (account != null) {
if (settings.getString(PREF_AUTH_TOKEN, null) == null) {
accountManager.manager.getAuthToken(account, AUTH_TOKEN_TYPE,
