Some notes: * This depends on 'androgenizer', a tool to generate Android-style Android.mk files from an autotools build system.
* This assumes that PA is run as the system daemon and configures accordingly. * In the Android build, libltdl is likely not available when configure is being run, and we know it will be so the check is manually overridden. * NEON support needs to be communicated from an upper-level Android.mk. * rpaths don't work on Android - you need LD_LIBRARY_PATH set. * Configuration files for /etc/pulse are shipped out of tree, since they vary from device to device. * The original patch was massive and ugly, but thanks Pekka Paalanen's work on Weston to break out common androgenizer snippets, we could greatly decrease the size of the Android-specific elements. * Since we don't use libtool for linking, we need to work around some symbol definition problems that turn up. This is done in a separate file (pulseaudio-android-symdef.c). More information about this at: http://www.sourceware.org/autobook/autobook/autobook_173.html (the example snippet needs some fixing to work with current libtool). --- Android.mk | 94
