although TelephonyManager is available since API 1, that call doesn't exists in the current code. try doing a cd android && ./gradlew clean and unlinking and re-linking the library

SubscriptionManager on the other hand need at least API 22 level

Yes SubscriptionManager needs API 22. so in that case, this module will not work in phones with API less than 22. or is there any workaround?

you can use TelephonyManager.getLine1Number but the person needs to have set his own number on the phone in "phone identity" and most people don't

best (sure) way is to ask the person for his number then read from SMS
