Add support for isDevice and isGooglePlayServiceAvailable

[niteshbalusu11]

Can you add support for new methods like isDevice which returns if its a real device or simulator.

isGooglePlayServiceAvailable helps with knowing if the android device is rooted.

Thanks for good suggestion! I'll add it this week

Oh one other thing that would be nice is, isHardwareKeyStoreAvailable or something similar which tells us if the device has a hardware backed keystore/secure enclave available.

Ah, library already provides the isEmulator property, so there's no need to add an isDevice property.
(You can simply use !isEmulator instead!)

Similarly, you can use the hasGms function instead of isGooglePlayServiceAvailable.
