Library does not work in Android prior Lollipop

[devilmac]

Hi all,

I added this library in my app but it does not work when I run the app on a device/emulator with Android prior Lollipop. I tried on Android 18 and 17 but it does not work at all. On Android API 19, 16 and 10 it works fine.

Could someone helps me, please?

Thanks.
