ViPER4Android FX

• Add this in device.mk: $(call inherit-product, packages/apps/ViPER4AndroidFX/config.mk)

Add this to your audio_effects.xml:

<library name="v4a_fx" path="libv4a_fx.so"/>
<effect name="v4a_standard_fx" library="v4a_fx" uuid="41d3c987-e6cf-11e3-a88a-11aba5d5c51b"/>

Also you need to address some SELinux denials in audioserver.te:

get_prop(audioserver, vendor_audio_prop)

allow audioserver unlabeled:file { read write open getattr };
allow hal_audio_default hal_audio_default:process { execmem };
