Android Question Problem with Excel Library

[Bourton]

Hello,
I hope someone can help me here with my problem! I have tried to insert the jexcelapi (Speak jxl. jar) in the B4A Library, in Trail version - without success. Now I have read that you cannot insert Librays in the Trail version. Now I have to bought the Full version. Furthermore the problem is in the Full version too. I think, that I need another file, a jxl. xml file, in addition to jxl. jar!

Can someone help me, please?


p.s. The tutorial on this page dosn´t run!

Are you using B4A (you are writing in B4A-Forum) or are you using B4J (the libraryname sounds like one for B4J)

I gave help to him in the german forum.
The problem was that he JUST used the jXL.jar in additional libs folder but not the b4a-wrapper (jar+xml). He have missed to download the lib from the posts attachments and put them into the additional libs folder.

a google-translated text i answered in the german forum today

Many libraries are simply based only on an official Api . Nothing needs to be made as these (depending on the SDK version ) but IS one available on the mobile phones here . You write the library and created the jar and xml and then paste it to B4A .
Most libraries are programmed according to this scheme .

Is a b4a library based on an 3rd party jar file (as in this case with the Excel Lib ( just said jXL.jar ) ) which is not standard with Android then it must be the wrapper ( the B4A library) ALSO 3rd party jar file to be copied in the Additional libs folder.

In the Lib DropboxSync e.g. is the dropbox sync -sdk - android.jar
or Google Analytics is the libGoogleAnalyticsServices.jar
or Paypal , it is the PayPalAndroidSDK - 2.8.2.jar

Just to name a few examples.
