-/**
- * In memory, debuggable network recommendation provider.
- *
- * <p>This example evaluates networks in a scan and picks the "least bad" network, returning a
- * result to the RecommendedNetworkEvaluator, regardless of configuration point.
- *
- * <p>This recommender is not yet recommended for non-development devices.
- *
- * <p>To debug:
- * $ adb shell dumpsys activity service NetworkRecommendationService
- *
- * <p>Clear stored scores:
- * $ adb shell dumpsys activity service NetworkRecommendationService clear
- *
- * <p>Score a network:
- * $ adb shell dumpsys activity service NetworkRecommendationService addScore $SCORE
- *
- * <p>SCORE: "Quoted SSID",bssid|$RSSI_CURVE|metered|captivePortal|BADGE
- *
- * <p>RSSI_CURVE: bucketWidth,score,score,score,score,...
- *
- * <p>curve, metered and captive portal are optional, as expressed by an empty value.
- *
- * <p>BADGE: NONE, SD, HD, 4K
- *
- * <p>All commands should be executed on one line, no spaces between each line of the command..
- * <p>Eg, A high quality, paid network with captive portal:
- * $ adb shell dumpsys activity service NetworkRecommendationService addScore \
- * '\"Metered\",aa:bb:cc:dd:ee:ff\|
- * 10,-128,-128,-128,-128,-128,-128,-128,-128,27,27,27,27,27,-128\|1\|1'
- *
- * <p>Eg, A high quality, unmetered network with captive portal:
- * $ adb shell dumpsys activity service NetworkRecommendationService addScore \
- * '\"Captive\",aa:bb:cc:dd:ee:ff\|
- * 10,-128,-128,-128,-128,-128,-128,-128,-128,28,28,28,28,28,-128\|0\|1'
- *
- * <p>Eg, A high quality, unmetered network with any bssid:
- * $ adb shell dumpsys activity service NetworkRecommendationService addScore \
- * '\"AnySsid\",00:00:00:00:00:00\|
- * 10,-128,-128,-128,-128,-128,-128,-128,-128,29,29,29,29,29,-128\|0\|0'
