Project Treble helps manufacturers to upgrade their devices to newer versions of Android with ease. This is achieved by separating the hardware-specific code from the Android OS through an HIDL interface. This allows the Android OS to be replaced without rebuilding the hardware-specific code. In addition, devices that support Project Treble can also install generic system images based from new versions of Android to experience the latest features on their devices. In theory, with the help of this initiative, devices should be getting faster Android version updates. ?
