Changes:

[ghost]

1. Add a switch in layout "KeyMapCreator" for enable nfc reader mode.
2. Add switch name at line 189 in strings.xml.
3. Add codes from line 197 to line 220 in KeyMapCreator.java.
4. Add users-sdk minSdkVersion 19.
   Reasons:
   Some phones (such as Huawei Honor 7 or Huawei Honor 4C) disable nfc intent through changed the mask in file /system/etc/libnfc-brcm_PLK.conf. So that application cannot receive any nfc intent from system. But if enable nfc reader mode, everything will be fine!

Hope author update this application to Google Play soon!

Hi. First of all: Thanks for contributing. I will look into this as soon as possible.

Regarding 4.:
I don't think I will raise the minSdkVersion to 19. There are over 7000 active installations on devices with SDK < 19. I don't want to lose them. At least not now.

Thank you for replying to me. This is the first time I submitted the code in the GitHub.There are some deviations in the description, please forgive me.

Regarding 4, I raised the minSdkVersion to 19 because the switch need minSdkVersion 19. You can change another way(for example: CheckBox) to implement that without raise minSdkVersion to 19.

The "Reasons: Some phones ..." which I wrote is for the reason why I change the code, not just for the Fourth point. You can use any other SDK version if you implement NFC reader mode.

Thank you very much.

I change the code for minSDKVersion back to normal

ping @ghost or someone else looking into the merge conflict?

[ikarus23]

Not sure if I'm comfortable with merging this. Not even sure we need the reader mode of Android since we use the foreground dispatch system.

As I don't see why MCT need these changes I will close this PR for now.
