A null pointer exception means that one of the variables you are passing is null, but the code tries to use it like it is there. In short the code tries to refer to a variable which is not present there. Have you checked that you have connected the scringo library project in your project? You can check it by right clicking your project file--> properties--> android--> in library field you need to select scringo resources library file and then click ok.

Thanks for your reply. Yes i have did it. The Scringo android 2.4.0 will not be having Scringoresources it will be having only scringo but i selected it. I have added the .jar files also.

Have you declared all the scringo activities in your manifest file? Also have you put your scringo app id and facebook app id in the scringo.properties file (you need to put it in the assets folder)?

Yes Of course i did it. And also i have added the appid in the scringo properties. I have previously worked on using scringo 2.3.2 & 2.3.1 . But i dint get any errors.

Ok, can you tell me where you added the scringo code? I mean in which activity file or fragment file?

I have added in the BT_activity_root_tabs..

Try adding it in the homescreen activity file instead of the BT_activity_root_tab file. Can you tell me which BT core are you using?

i can't add in homescreen activity because i want tabbed layout. And also i am using BT 2.9 old code. Scringo version 2.4.0

You mean BT 2.0? You can use scringo better if you add it in a separate activity instead of using it in the root file. Check one of my apps here, i will give code for it if you want... I have added the code in the bt blank screen in this app. Link- https://play.google.com/store/apps/details?id=com.wbhausamovies

No i am using BT 2.9 ....whether i have to add scringo.jar files.. Ok kindly provide the code

BT 2.9 is the selfhosting package. I am asking about which android core are you using. Is it the new core 3.0 or the old core 2.0. The new core compiles against android api level 14 and above whereas the old core compiles against api level 8 and above... You need to add scringo, twitter and gcm jar files in your project. Also you need to build configure those jar files.

Now i am getting error as "Type case expressions must be constant expressions App_rater.java /paloaltoproperties/src/com/pproperties line 199 Java Problem"

Now i am getting error as "Type case expressions must be constant expressions App_rater.java /paloaltoproperties/src/com/pproperties line 199 Java Problem"

I am using old core 2.0 only and api level is 11. I have configured the libs by giving add to build path.

Ok i have to go now. It would be better if we have a teamviewer session to sort out the errors you are getting. I will be online tomorrow at about 8 am. If you can manage that time mail me your teamviewer id and password, we will sort out the problem together.

I forgot to give you my email address- its- sandeepkurne (at) gmail (dot) com.

Ok after adding the .jar files only i got th error "Type case expressions must be constant expressions App_rater.java /paloaltoproperties/src/com/pproperties line 199 Java Problem"

Thanks for the reply.

Thanks for the reply.

Dont keep refreshing the forum page, if you refresh it, your earlier post will be posted again. Its too late for me to do any work now, you can catch me in the morning after 8 am. We will sort out your problem tomorrow.

Thanks for the reply.
