Note: The required interface board for nearly any transceiver is available from http://huprf.com/huprf/orders-prices
Scroll down to "panoramic adapter tap board", then click on "which PAT.” Assembled boards cost $15 US from G4HUP. (The TenTec Eagle radio already provides this tap.) If the SR dongle is attached directly to a point without an isolator (buffer), the SDR dongle would load down the IF too much and reception would suffer.
The app for your Android device is called "RF Analyzer" on the Google play store and costs $1.01.
