How to enable GNSS function in Android 8.1 HAL

[XiaofengZang]

Hello

I'm debugging GNSS function in ANDROID 8.1 system on imx8qm EVM board, GPS module is Quectel AG35 USB GPS.

GPS vendor give me only two files:

/system/lib64/hw/gps.default.so

/system/etc/gps_cfg.inf

I found android/hardware/interfaces/gnss is not compiled and service is not started , gps.default.so is not loaded.

How can I compile and use GNSS HAL function?

Thanks

after porting two files, logcat is:

Hi

these 3 module should be compiled:

vendor/bin/hw/android.hardware.gnss@1.0

vendor/etc/init/android.hardware.gnss@1.0-service.rc

vendor/lib64/hw/android.hardware.gnss@1.0-impl.so

Hi,

XiaofengZang‌ I am also facing similar issue.  Are you able to solve this, could you please share the updates.

Hello,

Unfortunately, we cannot provide this type of support. Since the driver that you are trying to add is not included in our BSP. However, the AOSP documentation describes the process to add a new driver to the Android images.

Adding a New Device  |  Android Open Source Project 

Unfortunately, this is as far as I could go.

I apologize for the inconveniences.

Best Regards,

Diego.
