PilferShush Jammer

Why? https://poal.co/s/conspiracy/559636

Research and project page : https://www.cityfreqs.com.au/pilfer.php

Android microphone checker and jamming application built for AOSP LineageOS.

Application for low battery requirement microphone passive jamming.

Calls audioRecord.startRecording() but DOES NOT READ THE AUDIO BUFFER.

Holds microphone access and should block user apps from gaining focus of microphone.

System telephone calls will override and bump the Jammer from the microphone.

Adds a notification as a reminder for running while in background.

Tested and blocks Google Voice search (user) app. Currently testing Chrome/Omnibox/Assistant app voice blocking.

Active jammer - tone and white noise versions, boost EQ for higher amplitude.

Scan user installed apps for key features, possible NUHF/ACR SDK package name matches and services/receivers running.

Jammers run as an instance of MediaRecorder in a foreground service
