How to enable GNSS function in Android 8.1 HAL

XiaofengZang — Wed, 15 Aug 2018 07:56:17 GMT

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:

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.

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
