Android :: GSON And The Flickr API Problems - JsonParseException When Deserializing Json
Jun 24, 2010
I'm building simple app, simply to learn the android ropes, that will display a list of the most recent photos uploaded to flickr. The app is constructed but it's crapping out when it tries to deserialize the json that I get back from flickr. Here is my error:
CODE:....................
From, the error I'm assuming it has something GSON doesn't like about the json that is being returned but I don't know enough about how java converts objects and other types of variables during the whole operation.
I'm not sure if you will need this but here is some of the code from the project:
CODE:..........
Here is FlickrPhotos:

But this gives the error shown at the end of the post.
It seems that there is some null pointer in listType... Here's a watch of listType:

I have the following json response from a url:
CODE:........
And here's how I'm doing the parse:
CODE:.......................
When I run the code, I get this error: ERROR/AndroidRuntime(823): java.lang.RuntimeException: No-args constructor for class com.project.driver.Driver$Post does not exist. Register an InstanceCreator with Gson for this type to fix this problem.
I'm having trouble with defining a suitable Driver.java for the parse. When I omit the 'last5comments' field, everything works fine, it's just the 'last5comments' bit I'm having trouble with...
Here is Driver.java:
CODE:......................

I have an application that queries a server (not under my control). The server returns a serialized object. I have the model for the class - however the problem is that the class is in "default package"... something not recognizable by Android ClassLoader. How can I resolve this issue?

I've got a strange problem here doing object de/serialization. In Java (JDK 1.6) I serialize some objects. In Android (SDK 1.1) I deserialize them. This work quite nice in general. In order to work with a server object (that uses Castor un/ marshalling) I do it like I always do. Same routines. Well, this time the file is only 172kb (my routines works pretty well with 2,4mb files) but the interlacing is quite deep. So it all starts with a class containing 2 ArrayLists. I tried de/serializing just ArrayList<String> and this works very well. But the XML file (which is unmarshalled with Castor and serialized in JDK) has 7000 lines. So I get this StackOverflowError....................

I'm playing arround with google gson for communication with my web back end at the moment.
This and this older posts indicate that there are some problems with gson on android.
I did some easy tests on the device already but maybe I just missed the bug.
Edit I'm now parsing a lot more data. Generic lists etc. still not encountered the bug.
Has anybody used gson on Android already? How does it work? Has somebody encountered bugs or something that will stop me from using it once it gets more complicated?

I am developing an Android application and I access a RESTfull web service that returns a JSON. This JSON I want to put it in POJOs but I think I am missing something as it doesn't work.
The JSON retuned is as follow:
CODE:.....
This is returned in response variable
CODE:.............
And now I try the following:
CODE:................
The error I get is:
CODE:.................
Here are the POJO objects
CODE:.......
To access the web service I use the class from: http://lukencode.com/2010/04/27/calling-web-services-in-android-using-httpclient/
Can't figure out how to continue. I found some subjects here but still didn't found a way around.

I'm relatively new to Java, eclipse and android so this could be a completely silly question, but I'm going to ask it none the less.
I've got a project I'm learning with to test connecting to the flickr api and simply displaying recent images. I'm at the point now where I want to parse the JSON received from flickr. I've downloaded gson 1.4 and added the zip to the java build path through "add external jars." It's successfully loaded and I can see google-gson under referenced libraries in the package explorer. My problem is, when I try to use it, I simply get an error.
Gson gson = new Gson();
It highlights Gson and says that "Gson cannot be resolved to a type." What am I missing here? It worked once and has since stopped. I've tried removing the jars, cleaning the project and re-adding the jars but it still doesn't work.

I tried DLing a Flickr app for android, "Flickr Free for Android". It downloaded just fine, but has been in the "installing" phase for going on 3 days. I cant "uninstall" because it technically isnt installed yet. I cant try to redownload because the market is showing that it is installing..

I have loads of photos on Flickr and Facebook and I want to set some of the photos to my contact list. When I open the facebook app, there is no way to see the photos. So I went to Albums and signed into my facebook page. I can see the photos and email them, but I cannot save them to my phone. Is the only way of doing this is going to the browser and long-clicking it to save? Is there an app which will copy them in bulk to my phone?

I got my desire last week. When I did the initial wizard setup, I put in my Facebook id and my Flickr one as well. I remember on that first day, I was quite pleased with the Flickr app and my photos. Now, it seems to be completely gone. If I look in All Programs, it's not there. If I go to Settings -> Applications -> Manage Applications, I can see Flickr (HTC Corporation) there in the list. If I choose it, I get the usual screen with the Clear Cache and About buttons.

How to stop Flickr from running in the phone and how to bring it back after disabling the app? I installed Flickr on my Droid Rezound. I didnt know it was already on the phone. I installed the Google Play version on top of the already installed version on my phone. I tested it out and decided not to keep it. I uninstalled the Google version and found the app was still trying to upload photos. Did some searching in the phone and disabled the phone version. After that it still tries to upload the photos. I signed out of Yahoo and Flickr and it still tries to upload. It's not that I care if the pics upload, but when I've taken lots of pics the upload gobbles battery life.

What's the deal with the Flickr integration?I thought I would transition over from Photobucket because it looked like it might make it easier to access and share photos.So I find out that I need a YahooID to sign up for Flickr.Why not something with Google (Picasa)?

I have been uploading my photos to Flickr using the built in Flickr integration. However, I notice that the geocoding does not get set in my Flickr account. When I browse the photos on my phone's card, the goecoding is in tact. Is this a limitation of Flickr or my Hero?

On 1.5 I used to get notifications all the time when someone uploaded new photos to flicker or changed their facebook account. Now I'm using the 2.1 leak v2 and I don't get any updates at all. What gives? I liked that feature. Any way to turn it back on?
And I do have the option set to update every 2 hours in the settings.

Ok everyone. I searched but didn't see anything quite similar so wanted to post. Do any of you know how to remove the Facebook and Flickr tabs at the bottom of the Gallery page? I've attached a screenshot.
They don't go away apparently when I remove the apk files but figured they had to be configured somewhere though it's probably compiled into the gallery app.
BTW: I know I can just uncheck the box in settings to show the tabs but I'd like to remove them completely.
If there is would you please let me know?

I picked up an Eris this weekend and I'm loving it! This is my first "smartphone" so I'm pretty pumped! I recently setup a link to my Flickr account and keep getting notifications everytime one of my contacts posts something to their account (can get overwhelming quickly). I tried looking for a way in-phone and on Flickr to disable the notifications but haven't found a solution so far. Anyone have an idea on how to disable/modify Flickr notifications?

I deleted my Flickr account (moved to ipernity) and uninstalled the flickr app. Now I'm getting the error "Authorise HTC Sense - flickr is not responding, try signing in". But of course I can't sign in, because I no longer have a flickr account.How do I remove Flickr from HTC Sense on my phone? Where are the options for HTC Sense itself located?
under "Settings:Apps:All apps" there was a "Flickr for HTC Sense". I can't uninstall that, or open it, only Force Stop.I can only see the main "HTC Sense" under Settings-Apps too, so can't open it directly to tell it to stop looking for Flickr.
