Can I use Linux system calls in android?

I want to create a service which can capture the touch coordinates of all the user interactions. This is part of my R & D Project. My goal is to build an authentication system. Can I use linux system calls from my app/service?

Please provide me with some good resources related to linux system calls in Android and how to use them?

You can use a limited number of calls, as exposed by the libc implementation for Android. But, what you indicate you would like to do (capture touch coordinates) will not be possible from a general app, only from within the Android framework. The input devices are managed by the framework's system_server process, which has the appropriate permissions to access kernel exposed driver interfaces (i.e. /dev/input/*). Apps developed with the NDK and SDK do not get access to these things as they are sandboxed by UID and process.

Yes you use system calls. One way is you can write your code in C/C++(where you can use ioctl calls) and Use Android NDK for calling C functions or you can Write Wrapper over C functions.
