/* There is no native way to get IMEI, so we have to call
 *  Java classes through JNI.
 *
 * But fear not: JNIpp (github.com/DmitrySkiba/itoa-jnipp) makes
 *  this task much easier.
 *
 * To get IMEI we need to perform the following calls:
 *
 * TelephonyManager telephony=(TelephonyManager)
 *   context.getSystemService(Context.TELEPHONY_SERVICE);
