renderscript :

Renderscript provides ScriptIntrinsicBlur which is a Gaussian blur filter. It has good visual quality and is just the fastest you realisticly get on Android. Google claims to be"typically 2-3x faster than a multithreaded C implementation and often 10x+ faster than a Java implementation". Renderscript is really sophisticated (using fastes processing device (GPU, ISP,etc.), etc.) and there is also thev8 support library for it making it compatible down to 2.2. Well at least in theory, through my own tests and reports from other devs it seems that it is not possible to use renderscript blindly, since the hardware/driver fragmentation seems to cause problems with some devices even with higher sdk lvl (e.g. I had troubles with the 4.1 Nexus S) so be careful and test on a lot devices. Here's a simple example that will get you starting
