私はいくつかの助けが必要です
GPS_thread アクティビティで gps 値 (経度、緯度、高度) を取得し、この値を他のアクティビティ (MapsFragment アクティビティと LoggingData アクティビティ) に送信します。
Sensor_thread から (IOIO マイクロコントローラーから) センサー値を送信し、この値を他のアクティビティにも送信します (SensorFragment アクティビティと
私はまだJavaでのプログラミングの初心者であり、基本的なJavaプログラミングを少ししか持っていないので、誰かが私を助けてくれることを願っています
どうもありがとうございます
