android - How to receive all sensors list (include not supported) -

i want enumerate all sensors supported google , verify if device support or not (include step counter, game rotation vector, geomagnetic rotation vector, significant motion, etc.)

i use sensor.type_all receive sensors, code below:

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_enumarte_sensors);      sensormanager sensormanager;     textview tvavailablesensors;      sensormanager = (sensormanager) getsystemservice(sensor_service);     list<sensor> sensors = sensormanager.getsensorlist(sensor.type_all);      tvavailablesensors = (textview) findviewbyid(r.id.tv_availablesensors);     tvavailablesensors.settext("sensors status:\n\n");      (sensor s : sensors)     {         boolean regsuccess = sensormanager.registerlistener(this, sensormanager.getdefaultsensor(s.gettype()), sensormanager.sensor_delay_normal);         tvavailablesensors.append(s.getname() + " (" + s.gettype() + ")  " + regsuccess + "\n");         if (regsuccess) sensormanager.unregisterlistener(this, sensormanager.getdefaultsensor(s.gettype()));     } } 

but receive status few sensors: accelerometer, ambient light, gyroscope, magnetic field, orientation, rotation vector, linear acceleration , gravity. (and didn't receive status step detector\counter, significant motion, etc.)

someone knows how can verify sensor supported on device , no?

edit:

to clear: know device not support sensors want receive list available sensors , status 1 support , no.

for example, have nexus 10, should receive list this:

accelerometer true

ambient ligh true

...

step counter false

significant motion false

i think such api not available, need check each of sensor type in code:

private sensormanager msensormanager; ... msensormanager = (sensormanager) getsystemservice(context.sensor_service); if (msensormanager.getdefaultsensor(sensor.type_magnetic_field) != null){   // success! there's magnetometer.   } else {   // failure! no magnetometer.   } 

and documentation quotes these type of sensors:

    type_ambient_temperature type_game_rotation_vector        type_geomagnetic_rotation_vector type_gravity type_gyroscope        type_gyroscope_uncalibrated type_light type_linear_acceleration        type_magnetic_field type_magnetic_field_uncalibrated     type_orientation    type_pressure type_proximity     type_relative_humidity    type_rotation_vector     type_significant_motion type_step_counter    type_step_detector     type_temperature
