in case you renamed the Java package and/or class names, you might still get an UnsatisfiedLinkError in case you did not rename the C++ native functions accordingly; for instance, if your package name is:

com.my.company.ImageTargets (instead of com.qualcomm.QCARSamples.ImageTargets);

and your main Java class is called:

com.my.company.ImageTargets.ImageTargets  (instead of  com.qualcomm.QCARSamples.ImageTargets.ImageTargets),

then the native functions will have to be renamed like in this example:

Then, as usual, remember to run ndk-build again and refresh the Java project in Eclipse.
