Note about waydroid-gbinder-config packages
A config file is required for libgbinder < 1.1.20. As of Sailfish 4.4, libgbinder 1.1.18 is shipped.
A config file is provided in packages waydroid-gbinder-config-hybris and waydroid-gbinder-config-mainline, adding a file to /etc/gbinder.d/ which details the binder nodes and aidl version used for the waydroid release.
A typical file looks like: [Protocol] /dev/puddlejumper = aidl2
/dev/vndpuddlejumper = aidl2 /dev/hwpuddlejumper = hidl
[ServiceManager]
/dev/puddlejumper = aidl2 /dev/vndpuddlejumper = aidl2 /dev/hwpuddlejumper = hidl
However, different devices have different binder files, or they may be in another location such as /dev/binderfs/.
Filenames are typically /dev/*puddlejumper and /dev/anbox-*binder and depending on the waydroid version, the aidl version needs to be 2 or 3.
Because of all these combinations, it is easier for a user to provide the config file for their device based on the description above, or the device parter can include the config file with their port.
Once libgbinder 1.1.20 is available in SailfishOS, the config file will no longer be required.
