Lấy về Danh Sách Tất Cả Sensor trên Thiết Bị Android

Code mẫu đọc tất cả cảm biến - Sensor trên thiết bị Android

SensorManager sm = (SensorManager) getSystemService(SENSOR_SERVICE);
List<Sensor> sensors = sm.getSensorList(Sensor.TYPE_ALL);
Log.d(TAG, "onCreate: Total Sensor: " + sensors.size());
for (Sensor s : sensors) {
   Log.d(TAG, "onCreate: " + s);
}

• Dòng 1: lấy về đối tượng SensorManager bởi phương thức getSystemService()
• Dòng 2: lấy về tất cả Sensor trên thiết bị Android.
• Dòng 3: xuất ra tổng số Sensor có trên thiết bị.
• Dòng 4, 5, 6: duyệt qua từng Sensor có trong danh sách và xuất ra thông tin chi tiết của từng Sensor.

Kết quả xuất ra sau khi chạy đoạn mã trên được thử nghiệm trên thiết bị Sky Pantech A900 là:
