安卓开发，开启服务service，并持续调用get请求接口的代码每3秒钟调用一次

//在AndroidManifest.xml  添加服务
  <service android:name="com.tjtykj.xtl.AutoUpdateService" ></service>

//在MainActivity中启动服务
  public static String ACdeviceToken = "";  //要读取的变量
public class MainActivity extends CordovaActivity
{
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        // enable Cordova apps to be started in the background
        Bundle extras = getIntent().getExtras();
        if (extras != null && extras.getBoolean("cdvStartInBackground", false)) {
            moveTaskToBack(true);
        }

        // Set by  in config.xml
        loadUrl(launchUrl);


        if (hasAgreedAgreement()) {
            PushAgent.getInstance(this).onAppStart();
            setDeviceToken();
        } else {
            showAgreementDialog();
        }


        Intent intent = new Intent(this, AutoUpdateService.class);
        startService(intent);
    }

//在AutoUpdateService文件中写具
