Hi, for some reasons your post has not shown up for a while, I just noticed it;

however, have you built the native code with ndk-build and then cleaned and refreshed the project in Eclipse ?

 E/QCAR(29307): The library libQCAR.so could not be loaded
 The library libUserDefinedTargets.so could not be loaded

i even use all the method which tell below, QCAR_SDK_ROOT is also configure Coreectly and also added .jar file.

yes , i use now it is giving only 1 error thar is 2nd one, first is resolved, from where did i get the file .so file of  " libUserDefinedTargets.so". it is again giving the error that is " The library libUserDefinedTargets.so could not be loaded"
