AlarmReceiver 与IntentService的使用

1：GetSmsService.java

public class GetSmsService extends IntentService{

    private AlarmManager alarmManager = null;

    private PendingIntent alarmIntent = null;

    

    public GetSmsService(){

        super("WtacService");

    }

    

    public GetSmsService(String name) {

        super(name);

    }



    @Override

    public IBinder onBind(Intent arg0) {

        return null;

    }

    

    @Override

    public void onCreate() {

        super.onCreate();

        alarmManager = (AlarmManager)this.getSystemService(Context.ALARM_SERVICE);

        String ALARM_ACTION = "com.wzh.receiver.ACTION_WTAC_ALAEM";

        Intent intentTo = new Intent(ALARM_ACTION);

        alarmIntent = PendingIntent.getBroadcast(this, 0, intentTo, 0);

    }

    

    @Override

    protected void onHandleIntent(Intent intent) {

        final Context context = this.getApplicationContext();

        

        int alarmType = AlarmManager.ELAPSED_REALTIME_WAKEUP;

        long triggerAtMillis = SystemClock.elapsedRealtime()+(5*1000);

        long intervalMillis = 5*1000;    //间隔时间

        alarmManager.setInexactRepeating(alarmType, triggerAtMillis, intervalMillis, alarmIntent);

        if(PhoneInfo.isConnectInternet(context)){

            System.out.println("从服务器获取数据："+new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));

            try {

                Thread.sleep(2*1000);

            } catch (InterruptedException e) {

                e.printStackTrace();

            }

            System.out.println("进行短信发送："+new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));

        }

    }



}

2：GetSmsAlarmReceiver.java

public class GetSmsAlarmReceiver extends BroadcastReceiver{



    @Override

    public void onReceive(Context context, Intent intent) {

        Intent startIntent = new Intent(context, GetSmsService.class);

        context.startService(startIntent);

    }



}

3：MainActivity.java

public class MainActivity extends Activity {

    

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        

        

    }

        

}

4：AndroidManifest.xml

<receiver

            android:name="com.wzh.service.GetSmsAlarmReceiver"

            android:enabled="true"

            android:exported="false" >

            <intent-filter>

                <action android:name="com.wzh.receiver.ACTION_WTAC_ALAEM" />

            </intent-filter>

        </receiver>



        <service

            android:name="com.wzh.service.GetSmsService"

            android:enabled="true"

            android:exported="false" />
