I am getting the following error in my google play crash reports. 

FacebookException : Cannot call LoginActivity with a null calling package. This can occur if the launchMode of the caller is singleInstance

I could not reproduce this issue. Has anyone encountered this issue before and solved it. I am giving the crash report below.

java.lang.RuntimeException: Unable to resume activity {com.games.mygame/com.facebook.LoginActivity}: com.facebook.FacebookException: Cannot call LoginActivity with a null calling package. This can occur if the launchMode of the caller is singleInstance.

Thanks in advance.

EDIT: I am calling my facebook related functions from a singleton class. Can that cause any issues.

  • @Sajmon i saw that link but could not make heads or tails out of the answer. Can you please explain a bit for me. – glo Mar 22 '13 at 12:32
  • Ask another question that details *specifically* what's confusing for you in the answer to the other question. – Shog9 Mar 27 '13 at 19:42
  • @Shog9 I do not understand whats causing this error in first place as i have not been able to reproduce this issue. This was reported in google play crash reports. And from what i have read in the other answer it has something to do with sharing or activity not expecting result or something. I seriously cant even understand the situation stated in it. – glo Apr 01 '13 at 04:19
