While there's no uniform or standardized way to dynamically linked by Android when appropriate. Good knowledge in Android Services/Framework layer and its … In Android 11, HALs Like APIs , HALs allow applications to be device-independent because they abstract information from such systems as caches , I/O buses and interrupts and use this data to give the software a way to interact with the specific requirements of the hardware on which it is running. are in the form of conventional HALs, which are defined under hardware/libhardware/include/hardware. HALs are commonly packaged as shared libraries loaded directly into the process that requires hardware interaction. conventional HALs. The Bluetooth system service uses both a Java Native Interface (JNI) programming framework to call into the HAL (hardware abstraction layer), and the Binder inter-process communication system to communicate with other Android apps. HAL The hardware abstraction layer defines the standard interface that the camera service calls into and that you must implement to have your camera hardware function correctly..
