how to access HAL layer

[Torsten Robitzki]

Hello,

I'm quite new to android development. My task at hand is, to access a certain function in the Bluetooth HAL layer (defined in hardware/libhardware/include/hardware/bluetooth.h). I've managed so far, to compile/link a cpp file to a shared object and to load that shared object into my Android Java App on a test phone. The required header (bluetooth.h) is not installed with the NDK, so now I wonder, what is the correct way to get the required libraries and headers to build a shared object against the Android HAL?

Thanks in advance and kind regards,

Torsten

HAL is an internal platform API, not an NDI API for apps.

You can only use HAL if you are building the platform.

Hi Glenn, Hi Pooja,

now, if managed to build against the HAL, by getting the sources (for the headers) and by extracting the needed shared objected from my test phone.

cheers,
