Android Question How to use JavaObject InitializeArray correctly ?

[somed3v3loper]

Hi all,

I was trying to use JTwitter for android and started by the following code

    Dim atl  As JavaObject
    atl.InitializeArray("winterwell.jtwitter.android.AndroidTwitterLogin" ,Array (Activity,conKey,conSecret,cb))

Here is the Java Example I am following :

 AndroidTwitterLogin atl = new AndroidTwitterLogin(myApp,
                                MY_TWITTER_KEY,MY_TWITTER_SECRET,MY_TWITTER_CALLBACK) {                               

        protected void onSuccess(Twitter jtwitter, String[] tokens) {
                jtwitter.setStatus("I can now post to Twitter!");
                // Recommended: store tokens in your app for future use
                // with the constructor OAuthSignpostClient(String consumerKey, String consumerSecret, String accessToken, String accessTokenSecret)
        }
};
atl.run();

but unfortunately I got the following error

java.lang.IllegalArgumentException: Array has incompatible type: class [Lwinterwell.jtwitter.android.AndroidTwitterLogin;

I think I must set type of each argument but I could not get that working.
I need your help .

Thanks in advance

Yes, you will have to make sure that the variables you are passing match those required by AndroidTwitterLogin.

Do you have the documentation? What should the signature be?

Here is the documentation and I thought I passed args correctly but got the same error mentioned above

Activity in B4a is a wrapper, you need to pass the actual Activity which you can get using the reflection library:

Dim R As Reflector
atl.InitializeArray("winterwell.jtwitter.android.AndroidTwitterLogin" ,Array (R.GetActivity,conKey,conSecret,cb))

The other three variables should be Strings.

I haven't tried it but I think that should work.

Thanks a lot Stevel but unfortunately , the same error .

Can you zip and post your project so I can try a few things?

Why are you using InitializeArray? You will need to use InitializeNewInstance to get the AndroidTwitterLogin object. But you will still need to use the Reflector to get the activity.

An array would have to contain all objects of the same class.

You cannot call this API with JavaObject. It is not possible to subclass an abstract class (or concrete class) with reflection.

I am not sure I understood you well but I changed to InitializeNewInstance and got the error :

java.lang.InstantiationException: can't instantiate class winterwell.jtwitter.android.AndroidTwitterLogin

Thanks Erel .
So is there any way to use this library ?

 

[Erel]

You can wrap it with a standard library.

Thank you very much Stevel and Erel .

Unfortunately I am not good at Java .
I think I should find another library .

Have you seen this one? http://www.b4x.com/android/forum/threads/twitter-sdk-wrapper.42587/

Yes I did but I was trying to use a complete library .
Thanks Stevel
