Hi, if you change LOCAL_MODULE value, then you must be aware that the library generated by the build process (ndk-build) will also change its name (check and see under the libs/armeabi folder); for instance, for "ImageTargets" the library generated is called "libImageTargets.so",
but if you change the LOCAL_MODULE name to (for example) "MyApp", the library produced will be called "libMyApp.so";
as a consequence, you need to adapt the Java source code that loads the native library (see the string NATIVE_LIB_SAMPLE in ImageTargets.java, which is used by the function loadLibrary()), otherwise at runtime the app will try to load a native library with the wrong name.
Also, be aware that chaging the LOCAL_MODULE in the android.mk file only impacts the name of the native library, but not the name of you application;
if you want to change the name of your App, you should look at renaming the main activity and changing the activity name also in the manifest.xml.
