i have multiple places where my app should upload files to Dropbox. when i try to upload a file the app is falling back to browser. if i use the DropboxApi object globally it says DropboxUnlinkedException.
I am posting my code
Dropbox.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// We create a new AuthSession so that we can use the Dropbox API.
AndroidAuthSession session = buildSession();
AJ_Constant.mApi = new DropboxAPI<AndroidAuthSession>(session);
// Basic Android widgets
// setContentView(R.layout.main);
if (mLoggedIn) {
logOut();
} else {
// Start the remote authentication
AJ_Constant.mApi.getSession().startAuthentication(DropBox.this);
}
}
#Override
protected void onResume() {
super.onResume();
if (session.authenticationSuccessful()) {
try {
// Mandatory call to complete the auth
session.finishAuthentication();
// Store it locally in our app for later use
TokenPair tokens = session.getAccessTokenPair();
storeKeys(tokens.key, tokens.secret);
} catch (IllegalStateException e) {
showToast("Couldn't authenticate with Dropbox:"
+ e.getLocalizedMessage());
Log.i(TAG, "Error authenticating", e);
}
}
}
The code for uploading file is :
(this code is in another file _someX.java)
com.dropbox.client2.DropboxAPI.Entry response = AJ_Constant.mApi.putFile(
AJ_Constant.ReportfileName, inputStream, file.length(),
null, null);
Should i re-build the session or get authentication process done everytime??
Please suggest me any solution
Thanks in advance
From the Android SDK docs (note the last line of code):
A typical authentication flow when no user access token pair is saved
is as follows:
AndroidAuthSession session = new AndroidAuthSession(myAppKeys, myAccessType);
// When user wants to link to Dropbox, within an activity:
session.startOAuth2Authentication(this);
// When user returns to your activity, after authentication:
if (session.authenticationSuccessful()) {
try {
session.finishAuthentication();
AccessTokenPair tokens = session.getAccessTokenPair();
// Store tokens.key, tokens.secret somewhere
} catch (IllegalStateException e) {
// Error handling
}
}
When a user returns to your app and you have tokens stored, just
create a new session with them:
AndroidAuthSession session = new AndroidAuthSession(
myAppKeys, myAccessType, new AccessTokenPair(storedAccessKey, storedAccessSecret));

In my app you can share the video you have just taken. I want to get the link to the video back to android so i can call another function that will input the link in the database. So basically i need to know how to get a link from video i just shared. I am using the following code.
String path;
//get the current active facebook session
Session session = Session.getActiveSession();
//If the session is open
if(session.isOpened()) {
//Get the list of permissions associated with the session
List<String> permissions = session.getPermissions();
//if the session does not have video_upload permission
if(!permissions.contains("video_upload")) {
//Get the permission from user to upload the video to facebook
Session.NewPermissionsRequest newPermissionsRequest = new Session.NewPermissionsRequest(Main_activity.this, Arrays.asList("video_upload"));
session.requestNewReadPermissions(newPermissionsRequest);
}
path = getImagePath(videoUri); //function that gets absolute path
//Create a new file for the video
File file = new File(path);
try {
//create a new request to upload video to the facebook
Request videoRequest = Request.newUploadVideoRequest(session, file, new Request.Callback() {
#Override
public void onCompleted(Response response) {
if(response.getError()==null)
{
Toast.makeText(Main_activity.this, "video shared successfully", Toast.LENGTH_SHORT).show();
Log.i("it","worked");
String atbilde =response.getGraphObject().getProperty("id").toString();
}
else
{
Toast.makeText(Uzdevumi.this, response.getError().getErrorMessage(), Toast.LENGTH_SHORT).show();
}
}
});
//Execute the request in a separate thread
videoRequest.executeAsync();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
//Session is not open
else {
Toast.makeText(getApplicationContext(), "Please login to facebook first", Toast.LENGTH_SHORT).show();
}
}
});
Edit: Changed the "String atbilde =" so it would store the video id, so now i just need to build the url by simply adding "https://www.facebook.com/video.php?v=" before the id.
The response you receive if the upload of the Video was successful should contain an id property, see
https://developers.facebook.com/docs/graph-api/reference/v2.1/user/videos/#publish
To get a playable URL, you can use this id from the response to query the Graph API like this:
/{video_id}?fields=source
Have a look at https://developers.facebook.com/docs/graph-api/reference/v2.1/video/
I am trying to connect my Android 4+ to Dropbox. I am using the latest version of the Core API provided by Dropbox.
Everything works fine until I try to save the user key and token when the user returns to my app after he authenticated the access using dropboxAPI.getSession().startOAuth2Authentication(activity).
When the user returns to my app after the authentication the following code should save key and token:
public boolean completeLogInAfterAuthentication() {
AndroidAuthSession session = dropboxAPI.getSession();
if (session.authenticationSuccessful()) {
try {
// Mandatory call to complete the auth
session.finishAuthentication();
// Store it locally in our app for later use
TokenPair tokens = session.getAccessTokenPair();
saveSessionKeys(tokens.key, tokens.secret);
return true;
} catch (IllegalStateExceptione) {
Log.d("MyLog", "Couldn't authenticate with Dropbox:" + e.getLocalizedMessage());
Log.d("MyLog", "Error authenticating", e);
}
}
return false;
}
This is quite exactly the code that is used in the DBRoulett Demo provided by Dropbox. Problem is, that session.getAccessTokenPair() returns null.
Because of this I cannot store any key or token and the user has to re-login everytime the app is started. How can I solve this?
All information I found just say, that getAccessTokenPair() could fail with an IllegalStateException but this is not the case here. The case that null is returned is not described anywhere. Any idea what I can do?
getAccessTokenPair is used to get an OAuth 1 access token (and secret). But you used OAuth 2, so you want getOAuth2AccessToken. From the tutorial (https://www.dropbox.com/developers/core/start/android):
protected void onResume() {
super.onResume();
if (mDBApi.getSession().authenticationSuccessful()) {
try {
// Required to complete auth, sets the access token on the session
mDBApi.getSession().finishAuthentication();
String accessToken = mDBApi.getSession().getOAuth2AccessToken();
} catch (IllegalStateException e) {
Log.i("DbAuthLog", "Error authenticating", e);
}
}
}
This is roughly the same thing that's in the DBRoulette sample, though it has code for both OAuth 1 and OAuth 2:
private void storeAuth(AndroidAuthSession session) {
// Store the OAuth 2 access token, if there is one.
String oauth2AccessToken = session.getOAuth2AccessToken();
if (oauth2AccessToken != null) {
SharedPreferences prefs = getSharedPreferences(ACCOUNT_PREFS_NAME, 0);
Editor edit = prefs.edit();
edit.putString(ACCESS_KEY_NAME, "oauth2:");
edit.putString(ACCESS_SECRET_NAME, oauth2AccessToken);
edit.commit();
return;
}
// Store the OAuth 1 access token, if there is one. This is only necessary if
// you're still using OAuth 1.
AccessTokenPair oauth1AccessToken = session.getAccessTokenPair();
if (oauth1AccessToken != null) {
SharedPreferences prefs = getSharedPreferences(ACCOUNT_PREFS_NAME, 0);
Editor edit = prefs.edit();
edit.putString(ACCESS_KEY_NAME, oauth1AccessToken.key);
edit.putString(ACCESS_SECRET_NAME, oauth1AccessToken.secret);
edit.commit();
return;
}
}
I am new to android and i started with importing sample app from GooglePlayServices in the android SDK.
The app "Plus" allows me to sign-in using G+ credentials. The Sample code is using GoogleApiClient.
This authenticates the App only on client. How do i send access token to my server Or store the access token in to my shared preferences??
Someone please Explain me which file i should add access token code to.?
I am assuming that you are able to login to GooglePlus successfully.Do something like below to get the AccessToken and store it using SharedPreference,
SharedPreferences SharedPreference;
Editor editor;
private class GetGoogleAuthTask extends AsyncTask<Void, Void, String> {
#Override
protected String doInBackground(Void... params) {
String token = null;
try {
token=GoogleAuthUtil.getToken(User_SignUp.this,Plus.AccountApi.getAccountName(mGoogleApiClient),"oauth2:"+Scopes.PLUS_LOGIN+" "+Scopes.PLUS_ME); //Change the permissions as per your need.
} catch (IOException transientEx) {
// Network or server error, try later
Log.e(TAG, transientEx.toString());
} catch (UserRecoverableAuthException e) {
// Recover (with e.getIntent())
Log.e(TAG, e.toString());
// Intent recover = e.getIntent();
// startActivityForResult(recover, REQUEST_CODE_TOKEN_AUTH);
} catch (GoogleAuthException authEx) {
// The call is not ever expected to succeed
// assuming you have already verified that
// Google Play services is installed.
Log.e(TAG, authEx.toString());
}
return token;
}
#Override
protected void onPostExecute(String token) {
if(token!=null)
{
Log.i(TAG, "Access token retrieved:" + token);
SharedPreference = getApplicationContext().getSharedPreferences("TokenPreference", 0);
editor = SharedPreference.edit();
editor.putString("access_token",token);
editor.commit();
}
}
}
Use below snippet where you need to get the accesstoken,
new GetGoogleAuthTask().execute();
I am creating an box android app that allows user to upload media files on their account.
I have set up my client id and client secret,it is authenticating my app too.
Uploading part is also done,but the problem i am facing is to save the auth data [which is obviously needed so user is not needed to login again and again]
Load, save and use of authentication data in Box Android API
the solution given above is not working [may b they have removed 'Utils.parseJSONStringIntoObject' method]
i can store the access token and refresh token but whats the point of saving when i cant use them to re authenticate a user
switch (requestCode)
{
case AUTHENTICATE_REQUEST:
if (resultCode == Activity.RESULT_CANCELED)
{
String failMessage = data.getStringExtra(OAuthActivity.ERROR_MESSAGE);
Toast.makeText(this, "Auth fail:" + failMessage, Toast.LENGTH_LONG).show();
// finish();
}
else
{
BoxAndroidOAuthData oauth = data.getParcelableExtra(OAuthActivity.BOX_CLIENT_OAUTH);
BoxAndroidClient client = new BoxAndroidClient(BoxSDKSampleApplication.CLIENT_ID, BoxSDKSampleApplication.CLIENT_SECRET, null, null);
client.authenticate(oauth);
String ACCESS_TOKEN=oauth.getAccessToken();
String REFRESH_TOKEN=oauth.getRefreshToken();
Editor editor = prefs.edit();
editor.putString("ACCESS_TOKEN", ACCESS_TOKEN);
editor.putString("REFRESH_TOKEN", REFRESH_TOKEN);
editor.commit();
BoxSDKSampleApplication app = (BoxSDKSampleApplication) getApplication();
client.addOAuthRefreshListener(new OAuthRefreshListener()
{
#Override
public void onRefresh(IAuthData newAuthData)
{
Log.d("OAuth", "oauth refreshed, new oauth access token is:" + newAuthData.getAccessToken());
//---------------------------------
BoxOAuthToken oauthObj=null;
try
{
oauthObj=getClient().getAuthData();
}
catch (AuthFatalFailureException e)
{
e.printStackTrace();
}
//saving refreshed oauth object in client
BoxAndroidOAuthData newAuthDataObj=new BoxAndroidOAuthData(oauthObj);
getClient().authenticate(newAuthDataObj);
}
});
app.setClient(client);
}
i have referred https://github.com/box/box-android-sdk-v2/tree/master/BoxSDKSample example
can any one tell me what i am doing wrong or any alternative to authenticate user using authdata,access token,refresh token?
UPDATE
refreshing token as they have said
'Our sdk auto refreshes OAuth access token when it expires. You will want to listen to the refresh events and update your stored token after refreshing.'
mClient.addOAuthRefreshListener(new OAuthRefreshListener()
{
#Override
public void onRefresh(IAuthData newAuthData)
{
Log.d("OAuth", "oauth refreshed, new oauth access token is:" + newAuthData.getAccessToken());
try
{
oauthObj=mClient.getAuthData();
mClient.authenticate(newAuthData);
String authToken=null;
//Storing oauth object in json string format
try
{
authToken = new BoxJSONParser(new AndroidBoxResourceHub()).convertBoxObjectToJSONString(newAuthData);
prefs.edit().putString("BOX_TOKEN", authToken).commit();
//saving authToken in shared Preferences
mClient.authenticate(newAuthData);
String ACCESS_TOKEN=newAuthData.getAccessToken();
String REFRESH_TOKEN=newAuthData.getRefreshToken();
Log.v("New Access token ", oauthObj.getAccessToken());
Log.v("New Refresh token ", oauthObj.getRefreshToken());
editor.putString("ACCESS_TOKEN", ACCESS_TOKEN);
editor.putString("REFRESH_TOKEN", REFRESH_TOKEN);
prefs.edit().putString("BOX_TOKEN", authToken).commit();
editor.commit();
}
catch (BoxJSONException e1)
{
e1.printStackTrace();
}
Log.v("Token Refreshed", " ");
}
catch (AuthFatalFailureException e)
{
e.printStackTrace();
}
}
});
app.setClient(mClient);
}
onClientAuthenticated();
In main activity,fetching stored token
try
{
stored_oauth_token=prefs.getString("BOX_TOKEN", null);
authData = new BoxJSONParser(new AndroidBoxResourceHub()).parseIntoBoxObject(stored_oauth_token, BoxAndroidOAuthData.class);
}
catch (BoxJSONException e)
{
e.printStackTrace();
}
mClient = new BoxAndroidClient(BoxSDKSampleApplication.CLIENT_ID, BoxSDKSampleApplication.CLIENT_SECRET, null, null);
mClient.authenticate(authData);
BoxSDKSampleApplication app = (BoxSDKSampleApplication) getApplication();
app.setClient(mClient);
i tried this app to upload a file after existing ,it did work
but after 60-70 odd minutes i couldn't upload file.
is there anything wrong in my code ?
This is how I initialize my Box client:
mClient = new BoxClient(BOX_CLIENT_ID, BOX_CLIENT_SECRET, null, null);
mClient.addOAuthRefreshListener(new OAuthRefreshListener() {
#Override
public void onRefresh(IAuthData newAuthData) {
try {
String authToken = new BoxJSONParser(new AndroidBoxResourceHub()).convertBoxObjectToJSONString(newAuthData);
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
prefs.edit().putString("box_token", authToken).commit();
} catch (BoxJSONException e) { }
}
});
mAuthToken = prefs.getString("box_token", null);
if (mAuthToken != null) {
BoxAndroidOAuthData authData = new BoxJSONParser(
new AndroidBoxResourceHub()
).parseIntoBoxObject(mAuthToken, BoxAndroidOAuthData.class);
mClient.authenticate(authData);
}
if (!mClient.isAuthenticated()) {
Intent intent = OAuthActivity.createOAuthActivityIntent(context, BOX_CLIENT_ID, BOX_CLIENT_SECRET, false, "https://yoururl.com/");
((Activity) context).startActivityForResult(intent, BOX_AUTH_REQUEST_CODE);
}
So for the auth refresh there are a couple of things to be considered:
box client automatically refreshes OAuth tokens, you'll want to attach a OAuthRefreshListener to listen to the refresh, if you want to persist, persist the oauth data passed into the refresh listener. The listener only update your persisted oauth data, you don't need to re-authenticate in the refresh listener, sdk does the re-authenticate automatically.
When you first initiate box client, you need to authenticate either by persisted auth, or the OAuth UI. The logic should be:
check client.isAuthenticated();
2.1 If authenticated, do nothing.
2.2 if not authenticated, try to check whether there's persisted auth data. If so, authenticate by client.authenticate(oauthdata);
2.3 if 2.2 failed, start OAuth UI flow.
2.4 at last, in case of OAuthFatalFailureException, start OAuth UI flow.
I want to use the dropbox in my application.I developed a sample application for upload and download files and it ask for authentication.
But I don't want to open login popup.
Is it possible access the dropbox by other users using default account(single account) login details?
So any user can use dropbox directly without login popup.
How to set access user access token pair manually.
AppKeyPair appKeys = new AppKeyPair(APP_KEY, APP_SECRET);
AndroidAuthSession session = new AndroidAuthSession(appKeys, ACCESS_TYPE);
if (mDBApi == null) {
mDBApi = new DropboxAPI<AndroidAuthSession>(session);
// mDBApi.getSession().startAuthentication(Main.this); //kicks off the web-based authentication
//you'll have to use the web-based authentication UI one-time to get the ######### values
String token_key="#########";
String token_seceret="#########";
AccessTokenPair tokens=new AccessTokenPair(token_key,token_seceret);
mDBApi.getSession().setAccessTokenPair(tokens);
// boolean v=mDBApi.getSession().authenticationSuccessful();
}
First time i run application in debug mode with break point i get the token key and token secret of by entering valid log in detail.and saved(noted) that credential and after that i set them manually as above code then can be log in successfully.
Yes. Have a look at their example app DBRoulette.
Please download the project from the below link name as DBRoulette
https://www.dropbox.com/developers/core
And create an app in https://www.dropbox.com/developers and get the api key and secret and add this both in DBRoulette.java and in AndroidManifest.xml ...it works..
In onCreate() write
AppKeyPair pair = new AppKeyPair(ACCESS_KEY, ACCESS_SECRET);
session = new AndroidAuthSession(pair, AccessType.APP_FOLDER);
dropbox = new DropboxAPI<AndroidAuthSession>(session);
SharedPreferences prefs = getSharedPreferences(DROPBOX_NAME, 0);
String key = prefs.getString(ACCESS_KEY, null);
String secret = prefs.getString(ACCESS_SECRET, null);
if (key != null && secret != null) {
Log.d("key secret", key + " " + secret);
AccessTokenPair token = new AccessTokenPair(key, secret);
dropbox.getSession().setAccessTokenPair(token);
}
if (key == null && secret == null)
dropbox.getSession().startAuthentication(DropboxActivity.this);
And in onResume() write
if (dropbox.getSession().isLinked()) {
try {
loggedIn(true);
doAction();
} catch (IllegalStateException e) {
Toast.makeText(this, "Error during Dropbox authentication",
Toast.LENGTH_SHORT).show();
}
} else if (dropbox.getSession().authenticationSuccessful()) {
try {
session.finishAuthentication();
TokenPair tokens = session.getAccessTokenPair();
SharedPreferences prefs = getSharedPreferences(DROPBOX_NAME, 0);
Editor editor = prefs.edit();
editor.putString(ACCESS_KEY, tokens.key);
editor.putString(ACCESS_SECRET, tokens.secret);
editor.commit();
loggedIn(true);
doAction();
} catch (IllegalStateException e) {
Toast.makeText(this, "Error during Dropbox authentication",
Toast.LENGTH_SHORT).show();
}
}
It worked fine for me
