Hi  (I'm mlg),
Jiwigo uses apache HTTPClient to connect to piwigo's webservice. I don't know if you can use it in an android application.
The project structure is the following :
fr.mael.jiwigo.dao -> calls to webservice
fr.mael.jiwigo.service -> calls to dao
fr.mael.jiwigo.ui -> calls to service
The Data Access Objects (dao) use a "SessionManager" (which is in fr.mael.jiwigo.transverse.session) to execute queries on the webservice.
This method executes the methods on the webservice and returns the result as a string :

    public String executerReturnString(String methode, String... parametres) {
  if (parametres.length % 2 != 0 && !(parametres == null)) {
      try {
    throw new Exception("Le nombre de parametres doit etre pair");
      } catch (Exception e) {
    LOG.error(Outil.getStackTrace(e));
    return null;
      }
  }
  PostMethod method = new PostMethod(url);
  method.addParameter("method", methode);
  for (int i = 0; i < parametres.length; i += 2) {
      method.addParameter(parametres[i], parametres[i + 1]);
  }
  try {
      client.executeMethod(method);
      return (method.getResponseBodyAsString());
  } catch (HttpException e) {
      // TODO Auto-generated catch block
      LOG.error(Outil.getStackTrace(e));
  } catch (IOException e) {
      // TODO Auto-generated catch block
      LOG.error(Outil.getStackTrace(e));
  } catch (IllegalArgumentException e) {
      LOG.error(Outil.getStackTrace(e));
      JOptionPane.showMessageDialog(null, Messages.getMessage("connexionDialog_connexionError"), Messages
        .getMessage("error"), JOptionPane.ERROR_MESSAGE);
  } finally {
      method.releaseConnection();
  }
  return null;

    }

The parameters are : methode : the name of the method of the webservice
parameters : the parameters of the method
for instance, I can use : executerReturnString("pwg.categories.add","name", "the name", "parent", "15");

I share the view that the android application for Gallery 2 could be a really good starting point as it already implements several important features (like cache, upload, reusing standard zoom feature, camera support).
Now, we need the point of view of anthony43 about the feasability and the requirements. And next, we need a motivated Android developper.

Thank you anthony43 for the current state of G2Android. The separation of the communication interfaces and other parts of the application will be nice indeed. Your steps are very clear and I have no doubt Piwigo will feel comfortable in the future *Android application :-)

* Browse Jiwigo source code
* Jiwigo source code SVN repository

mlg, would you like to take a look at the g3 java api and see if a similar API could be built, based on what was already done in Jiwigo?

Let's keep French language either on the French forum or in private emails ;-) (mlg/fcoiffie speak French)

To reply to myself : It's quite easy :
1. Install the Android SDK and Eclipse http://developer.android.com/sdk/index.html
2. Checkout the application with svn checkout http://g2android.googlecode.com/svn/trunk/ g2android-read-only
3. In Eclipse, Import the existing project in the workspace by selecting g2android-read-only/g2android
4. In Eclipse, select Project | Clean... to remove the strange error about the missing 'gen' directory
5. With Context menu on the project, select Run As | Android application to launch it

Hello all !
I (really ;-) ) started working on the followup of G2Android, ReGalAndroid
It is hosted on github, is pretty unstable right now, but you can definitely have a look at the code here :
http://github.com/anthonydahanne/ReGalAndroid

Here is actually the remote gallery interface that I could extract from G2Android :
http://github.com/anthonydahanne/ReGalA … llery.java

Well, not really clean for now as I'm not done yet with the refactoring ; I'm currently trying to make my g3 java api client
http://github.com/anthonydahanne/g3-java-client
fit with this interface; but hey,  I have problems as G2 and G3 remote APIs are really different...so I guess Piwigo one should be !

Anyway, I'll get back to you all when I feel the interface is stable enough to start adding piwigo support from Jiwigo (or any other java client) source code
Bye,
Anthony

Hello all !
I'm about to release the first stable version of ReGalAndroid (the follow-up of G2Android) as I have now finished to re design the code (true separation between the Java Remote API for G2 and G3 and the Android app).
Currently, I have G2 fully working (all the features that were already in g2Android) and G3 authentication, albums and photos browsing.
I had a look at Jiwigo and it seems to me that there is everything in it I need to add Piwigo support to ReGalAndroid.
I wrote to mlg (the author of Jiwigo) a few days ago to ask him to split his project in 2 modules (a remote api one and a graphical one; for me to only import the remote api module) but I did not get any answers yet...
Feel free to have a look at the codebase of ReGalAndroid; I should upload a binary any time soon (I need some art now...)

Piwigo support is near ;-)

Hello all !
Finally, here it is, first beta version of ReGalAndroid with Piwigo support !
You can get if there :
http://code.google.com/p/regalandroid/downloads/list

Please test it, report any bugs on the issues page :
http://code.google.com/p/regalandroid/issues/list

Don't forget that just authentication, browsing albums and browsing photos is implemented !

You can have a look at the code there :
https://github.com/anthonydahanne/ReGalAndroid

Many, many thanks to Mael, for your help and your authorisation to use Jiwigo code ! It helped a lot !

I'm waiting for your impressions / suggestions/ critics !
It will be on the market before Xmas.

I made some tests and it basically works.
In fact, the main problem may be due to the Piwigo gallery which is hosted on a slow server : I got some "net.dahanne.gallery.commons.remote. GalleryConnectionException : No wrapped connection." or "net.dahanne.gallery.commons.remote. GalleryConnectionException : Request aborted"

Moreover, on photos where I got errors, now, the cache contains an empty photo (and there is no way to force to reload it).

It seems that the application doesn't manage correctly filenames with accent : With a photo, I get "regalandroid.utils.FileHandlingException : <my filename with é and è > (Invalid Argument)"

But, I would like to reproduce all these problems with the android simulator on a PC.

And, of course, thank you very much for this work !
