Actually,there is no error in run time log.let me explain the actual step i followed to developed the development
1.i have7 image targets+3dmodels+audio where i add all of them in one scene;
2.i also have add some scripts......ImageTargetAudioPlay(for audio),DefaultTrackableEventHandler(to make the 3d object appear only after the marker was detected),ImageTargetTrackableEventHandler(for the marke).i have edited the name according to each marker's name exp:ImageTargetTrackableEventHandlerKarbohidrat,ImageTargetTrackableEventHandlerProtein......etc) and i followed the sample app and add the Scene Manager to hiercacy
3.Then,produce .apk ,install it in android phone.I have change the marker of the imagetargets-2-8-9_SAMPLE APPS and install it in android phone,its fuctioning and the marker is detected and the tea pot is appeear..... but when develop my project in same way ,the application can installed in android phone and open the application but the screen goes dark blank.....then,hang.....the application close automatically......
4.I have attached below all the scripts that i have used
5. i think i have left some scripts here but im totally lost......
