Answer 1

You need to install JMeter's self-signed certificate so JMeter could decrypt and record HTTPS traffic.

1. Locate ApacheJMeterTemporaryRootCA.crt file under "bin" folder of your JMeter installation
2. Send it to mobile device vie bluetooth or email or whatever way plays for you
3. Tap on the certificate in email attachment or file manager and follow Android OS instructions to get it installed
4. Remember that the certificate has limited life time so you will have to repeat the procedure each 7 days

See HTTPS recording and certificates section of the HTTP(S) Test Script Recorder User Manual entry for more details.

Also be aware of an alternative solution of recording mobile device traffic, it automates not only certificate installation process, but it's capable of exporting recorded scenarios in "SmartJMX" mode with automated correlation applied, it means that it will generate all the necessary Post Processors to handle dynamic parameters, see How to Cut Your JMeter Scripting Time by 80% for more information.
