crash on android below 5

[amir1376irani]

Hi
Tnx for this great app :)
I have tested your app on lenovo A3300HV (stock android 4.4.2)
it works fine in this tabs : CPU - GPU - RAM - STORAGE - SCREEN
and this tabs are faulty : ANDROID - HARDWARE - SENSORS

---

After opening each faulty tab, it shows exactly same error :

---

To reproduce this: run it on this android version if you have any device or just make an emulator with this version of android (api level 16 to 20) it must appear!

---

So i checked output of logcat for ANDROID, HARDWARE and SENSORS tabs and saw something meaningful which were same (don't hestitate about that pid thing {6032}, thats a random number as process identifier for the OS and will be changed on every run):

I checked your app manifest it says minSDK is 16
You have defined this in line 6 of build.gradle

So for supporting this versions (api 16 to 20) you need to add some checks of version for every method, which maybe not supported or not available and just skip those tests if not possible to messure!

Fixed in 4.5.0
