- mem
- HardwareBuffer
A android.hardware.HardwareBuffer shared memory object.
Returns
A android.hardware.SensorDirectChannel object.
- Attributes
Remarks
Create a sensor direct channel backed by shared memory wrapped in HardwareBuffer object.
The resulting channel can be used for delivering sensor events to native code, other processes, GPU/DSP or other co-processors without CPU intervention. This is the recommanded for high performance sensor applications that use high sensor rates (e.g. greater than 200Hz) and cares about sensor event latency.
Use the returned android.hardware.SensorDirectChannel object to configure direct report of sensor events. After use, call android.hardware.SensorDirectChannel#close() to free up resource in sensor system associated with the direct channel.
