Android battery temperature and voltage wrong values -

-

i have tested code. on 2 phones, work´s ok , give me right values. on tablet same code returns temperature value 0 , voltage value 3 (wrong values).

can give me understand ? each code try, return values.

thank´s.

@override public view oncreateview(layoutinflater inflater, viewgroup container,         bundle savedinstancestate) {     // todo auto-generated method stub            view rootview = inflater.inflate(r.layout.battery_fragment1, container, false);                  rootview.setlayoutparams(new layoutparams(layoutparams.match_parent,layoutparams.match_parent ));              getactivity().registerreceiver(mbatinforeceiver, new intentfilter(              intent.action_battery_changed));      battemp=(textview)rootview.findviewbyid(r.id.batterystatus);        return rootview; }  private broadcastreceiver mbatinforeceiver = new broadcastreceiver() {      @override      public void onreceive(context c, intent intent) {            level = intent.getintextra(batterymanager.extra_level, 0);          health = intent.getintextra(batterymanager.extra_health, 0);   //       icon_small = intent.getintextra(batterymanager.extra_icon_small, 0);          plugged = intent.getintextra(batterymanager.extra_plugged, 0);          present = intent.getextras().getboolean(                  batterymanager.extra_present);          scale = intent.getintextra(batterymanager.extra_scale, 0);          status = intent.getintextra(batterymanager.extra_status, 0);          technology = intent.getextras().getstring(                  batterymanager.extra_technology);          temperature = intent.getintextra(batterymanager.extra_temperature,                  -1);          voltage = intent.getintextra(batterymanager.extra_voltage, 0);       //     pb.setprogress(level);            battemp.settext("level: " + level + "\n\n" + "health: " + health + "\n\n"                  + "\n\n" +                    "plugged: " + plugged + "\n\n" + "present: " + present + "\n\n"                  + "scale: " + scale + "\n\n" + "status: " + status + "\n\n"                  + "technology: " + technology + "\n\n" + "temperature: "                  + temperature + "\n\n" + "voltage: " + voltage + "\n\n");        }  };

probably devices return v, not mv. use this:

    float v = (float) voltage;     if (voltage > 12)         v = (float) voltage / 1000;     float t = (float) temp / 10;
