Ultra-accurate Android phone pedometer development _android

The advances is available on Huawei, the app uses back-office service meter, so as long as the app is not killed by the phone in the background can also be normal advances. Image above:

1. Need to add permissions in Androidmanifest.xml

<!--advances Required permissions-->
 <uses-permission android:name= "Android.permission.VIBRATE"/>
 < Uses-permission android:name= "Android.permission.WRITE_SETTINGS"/>
 <uses-feature android:name= " Android.hardware.sensor.accelerometer "/>
 <uses-permission android:name=" android.permission.RECEIVE_ Boot_completed "/>
 <uses-permission android:name=" Android.permission.MOUNT_UNMOUNT_FILESYSTEMS "/>"
 <uses-feature
 android:name= "Android.hardware.sensor.stepcounter"
 android:required= "true"/>
 <uses-feature
 android:name= "Android.hardware.sensor.stepdetector"
 android:required= "true"/ >

2. Test whether the handset supports the advances

 /**
 * To determine whether the device supports advances
 * *
 @param context
 * @return
 /@TargetApi (build.version_codes. KitKat) Public
 Static Boolean issupportstepcountsensor (context context) {
 //Get instance of sensor manager
 Sensormanager Sensormanager = (sensormanager) context
  . Getsystemservice. Sensor_service);
 Sensor countsensor = Sensormanager.getdefaultsensor (sensor.type_step_counter);
 Sensor detectorsensor = Sensormanager.getdefaultsensor (sensor.type_step_detector);
 return countsensor!= Null | | Detectorsensor!= null;
 }

3. Function use

Private Boolean isbind = false;
    Private Messenger Mgetreplymessenger = new Messenger (new Handler (this));
   Private Messenger Messenger;
        /** * Open Pedometer service * * private void Setupservice () {Intent Intent = new Intent (this, stepservice.class);
        Isbind = Bindservice (Intent, Conn, context.bind_auto_create);

    StartService (Intent); /** * Get steps from service services * * @param msg * @return/@Override

    public boolean handlemessage (Message msg) {        switch (
Msg.what) {            case constant.msg_from_server:                 Cc.setcurrentcount (
10000, Msg.getdata (). GETINT ("step"));
                break;
       }         return false;    }    /**      * A interface for querying the status of application services (application service) nbsp;    * More detailed information can be referenced in the service and Context.bindservice () description      * And many callback methods from the system, The Serviceconnection method is called     /    Serviceconnection conn = new in the main thread of the process. Serviceconnection () {       /**          * This method is invoked when establishing a connection to a service, and Android is currently connected to the services through the ibind mechanism.          * @param name is actually connected to the service component names           * The ibind of the communication channel of the service @param services, which can be accessed through service           *         @Override         Public void onserviceconnected (componentname name, IBinder service) {             try {              
  Messenger = new Messenger (service);                 msg =
Message.obtain (null, constant.msg_from_client);                 Msg.replyto =
Mgetreplymessenger;                 messenger.send (msg);             catch (RemoteException e) {   
             E.printstacktrace ();
           }        }       /**          *
Call the party when the connection to the service is lost          * This often happens when the service's process crashes or is killed.          * This method will not remove the connection to the service and will still invoke onserviceconnected ()   when it restarts         * @param name missing component name for connection          */        @Override         public void onservicedisconnected (componentname name) {       }    };
