Android Question [solved] Facebook login fails

Hi All,

I am trying to apply the facebook login following the example on this link but it fails in compiling.

I have tried to re-add the required resources, removing and installing the FB sdk 11.20, researched the forum and can only see this link referring to the error but can not find a solution or any other similar problem.

Current SDK version: 6609375

I am using B4xPages in the attached project; however I have added the facebook.initialize in starter.

The error received is:

Error while compilation:
B4A Version: 11.50

B4A line: 13
src\net\fitcap\ error: method Initialize in class FacebookSdkWrapper cannot be applied to given types;
  required: no arguments
  found: BA
  reason: actual and formal argument lists differ in length

Note: I also tried to add the facebook.initialize to the B4XMainpage but received similar error.

Attached is the project that fails with this error.

I appreciate if anyone had this problem before to shed some lights, thank you for your help!

Thank you so much Erel! I checked the internal folder and can see there was a facebook.jar file!! I have not added it there; however after removing the file, it is now working fine.

I really appreciate ur help! I would have never thought to search on this folder!
