Android.mk: Add support for Android 11
If we configure Replicant 11, libsamsung-ipc and libsamsung-ril
to have both libraries in /system/lib/, tools work fine on the
Galaxy SIII (GT-I9300):
# find -name libsamsung-ril.so 2>/dev/null
./system/lib/libsamsung-ril.so
# find -name libsamsung-ipc.so 2>/dev/null
./system/lib/libsamsung-ipc.so
# find -name nv_data-md5 2>/dev/null
./system/bin/nv_data-md5
# nv_data-md5
Usage: nv_data-md5 [nv_data.bin]
And libsamsung-ril tries to load libsamsung-ipc from the right
location in /system/lib/, but it fails due to the vendor and system
separation:
01-14 15:50:57.739 1475 1475 E RILD : dlopen failed:
dlopen failed: library "/system/lib/libsamsung-ril.so"
needed or dlopened by "/system/vendor/bin/hw/rild" is not
accessible for the namespace "(default)"
Adding LOCAL_PROPRIETARY_MODULE fixes that. Note that the name
of that property can be misleading here: libsamsung-ipc is free
software and shall remain free software.
Instead we need to understand LOCAL_PROPRIETARY_MODULE as a way
to tell the Android build system that libsamsung-ipc is not part
of the base Android code but instead that it is code that is
specific to a device, set of devices and/or Android distribution.
LOCAL_MODULE_RELATIVE_PATH cannot be used instead: even if the
binaies end up in /vendor/bin/hw/, and that the libraries ends
up in /vendor/lib/hw/, for some reasons the libraries can't be
found:
i9300:/ # /system/vendor/bin/hw/nv_data-md5
CANNOT LINK EXECUTABLE "/system/vendor/bin/hw/nv_data-md5":
library "libsamsung-ipc.so" not found: needed by main executable
And most importantly, rild has the same issue than before:
E RILD : dlopen failed: dlopen failed: library
"libsamsung-ipc.so" not found: needed by
/system/vendor/lib/hw/libsamsung-ril.so
in namespace (default)
