Image Effects for Android?

Question

I am making an app which will allow the user to click a picture and then apply various effect filters on the picture. Basically, I want to create an app similar to Pudding Camera.

I researched a lot and came across 3 options to do this:-

1) Use OpenCV and implement all the effects manually [not my first priority as it uses a lot of time, but will do this if all else is unfruitful].

2) Use a library like ImageMagick / ImageJ / Marvin by porting to Android via NDK.

3) Use a library like jjil.

Now I want to know which is the best way to proceed. My priorities are:-

1) I want to be able to tweak the effects and maybe create new custom effects of my own.

2) I want it to run fast as I want my app to be quick and responsive.

3) I want to use a library which is easiest to learn as I am not an expert in image proccesing.

Please help!

OpenCV works well for Android 2.3 and beyond, you can consider FastCV by Qualcomm, which is like OpenCV but more optimized for Qualcomm chips. I don't not recommend JJIL, it hasn't been updated for ever and only works on very old version of Android.
