ViPER4Android FX

Integrate V4A by completing these three steps:

1. Build System: Add the config to device.mk:

   $(call inherit-product, packages/apps/ViPER4AndroidFX/config.mk)

2. Audio Effects: Add these lines to the <libraries> block in audio_effects.xml (/vendor/etc/ or /etc/):

   <library name="v4a_re" path="libv4a_re.so"/>
   <effect name="v4a_standard_re" library="v4a_re" uuid="90380da3-8536-4744-a6a3-5731970e640f"/>

3. SELinux Policy: Add these rules to your audioserver.te file:

   get_prop(audioserver, vendor_audio_prop) # If Google or MTK device skip line
   
   allow audioserver unlabeled:file { read write open getattr };
   allow hal_audio_default hal_audio_default:process { execmem };
