where is imagetarget.c?

where is Imaetarget .c sample file located?? i found a file Imagetarget.java in C:\development\android\qcar-android-1-0-6\samples\ImageTargets\src\com\qualcomm\QCARSamples\ImageTargets. this folder contains other java files also(viz.debublog.java,imagetargetarenderer.java,QCARsampleGLview.java and texture.java) whaat are those files?

ImageTargets.cpp is located in the "jni" folder. The Java files are responsible for setting up the Android activity and the OpenGL view. They also initialize QCAR, with calls down to native as needed. The native (cpp) files handle tracking events and rendering.

thanks for your answer sir. should we write all those files(exceppt imagetargets.cpp) inside that folder or they are generated automatically?(i have same quest with those java files)

We recommend using one of the sample projects as a starting point, as you will most likely want your project to use a similar setup. These files aren't automatically generated. You can copy a sample and rename the package and classes as required.
