Issue description

Hi, I am trying to modify your library as per my requirement I need the front facing camera to scan card information. I have spent approximately 32 hours to just run your source code on my android studio from here: https://github.com/card-io/card.io-Android-source

I was having the different type of issues while gradle building anyways, from the given steps:

clone this repo -> Done

$ cd card.io-Android-source -> Done

init its dmz submodule: git submodule sync; git submodule update --init --recursive -> Done

$ cp local.properties.example local.properties **(Here i got an error "The system cannot find the file specified." but i have added the path of sdk and ndk in my local.properties file here is the way i have done it:

ndk.dir=C:\Users\Lenovo\AppData\Local\Android\Sdk\ndk-bundle sdk.dir=C:\Users\Lenovo\AppData\Local\Android\Sdk)**

Edit local.properties with your env (Assuming you've defined $ANDROID_NDK correctly, run $ echo "$ANDROID_NDK" "$ANDROID_SDK" -> I am unable to understand, are you trying to say that i have to set environment variables for ndk and sdk then i should check these variables containing the correct path?

$ ./gradlew clean assembleDebug --> Then i ran this command on my android studio terminal and i am getting this response :
