Audio Pitch and Tempo modification

Question

I need to modify pitch or tempo of an audio, but need to do them separately. Is there any example in Android for that or any library which provides support for Android.

I want to avoid using NDK/JNI for this, since I am not that good into it.

I have already seen Many libraries, although they have a nice tutorial, but I am unable to import them to Eclipse Android project. Help is appreciated :-)

Here some cool demo links from Tarsos:
