Display an Android Sensors List

The constant SensorManager.SENSOR_ALL is deprecated and doesn't seem to work anymore.

Query the sensor list with Sensor.TYPE_ALL instead and it should work (my emulator returns a "Goldfish 3-axis Accelerometer").

You can try this code:-

package com.example.sensor;import java.util.List;import android.content.Context;import android.hardware.Sensor;import android.hardware.SensorManager;import android.os.Bundle;import android.support.v7.app.ActionBarActivity;import android.widget.ArrayAdapter;import android.widget.ListView;public class MainActivity extends ActionBarActivity {SensorManager smm;List<Sensor> sensor;ListView lv;@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    smm = (SensorManager) getSystemService(Context.SENSOR_SERVICE);    lv = (ListView) findViewById (R.id.listView1);    sensor = smm.getSensorList(Sensor.TYPE_ALL);    lv.setAdapter(new ArrayAdapter<Sensor>(this, android.R.layout.simple_list_item_1,  sensor));}}

Just put a list view in your xml layout.

You can try listing the sensors as below:-

String cAPP_FOLDER = Path of your folder

String cSENSOR_FILE = Name of your file

// Create a file to export the sensor info.File fp = new File(cAPP_FOLDER + cSENSOR_FILE);fp.createNewFile();PrintWriter pw = new PrintWriter(new FileWriter(fp, true));SensorManager oSM = (SensorManager) context.getSystemService(Context.SENSOR_SERVICE);List<Sensor> sensorsList = oSM.getSensorList(Sensor.TYPE_ALL);for (Sensor s : sensorsList) {    pw.write(s.toString() + "\n");}pw.close();
