Question

我有GPS跟踪应用程序主要目标是每隔5分钟将GPS坐标保存到支持的数据库。所以我创建了Service＆amp; receiver因为即使我的应用程序没有打开/运行，这也应该有用。

用户输入执行代码后，会创建数据库并转到欢迎屏幕。在那里它开始GPS捕获＆amp;将其保存到PDA数据库调用服务上传。我有接收器，当电话号为Booted时，它会启动此接收器＆amp;接收方呼叫服务。

我的问题是接收方没有拨打电话服务。它没有去服务类。

  protected void onStop(){
    super.onStop();
    if(gpsReceiver != null){
        unregisterReceiver(gpsReceiver);
    }
}

 @Override
 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.home);

    gpsReceiver = new GpsReceiver();
    IntentFilter intentFilter1 = new IntentFilter(Intent.ACTION_BOOT_COMPLETED);
    intentFilter1.addAction(Intent.ACTION_BOOT_COMPLETED);
    intentFilter1.addAction(Intent.ACTION_POWER_CONNECTED);
    intentFilter1.addAction(Intent.ACTION_SCREEN_ON);
    registerReceiver(gpsReceiver, intentFilter1);

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    locationManager.requestLocationUpdates(
           LocationManager.GPS_PROVIDER, 
           MINIMUM_TIME_BETWEEN_UPDATES, 
           MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
           new MyLocationListener()
    );
    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, new MyLocationListener());
 }

 private class MyLocationListener implements LocationListener {
        public void onLocationChanged(Location location) {
            String message = String.format( "Location \n Longitude: %1$s \n Latitude: %2$s", location.getLongitude(), location.getLatitude());
            longitude = location.getLongitude();
            latitude =location.getLatitude();

            //save GPS coordinate to PDA DB
            GPSDBAdapter dbAdapter = GPSDBAdapter.getDBAdapterInstance(HomeActivity.this);
            dbAdapter.openDataBase();
            dbAdapter.insertGPS(longitude, latitude, "MASS", deserializeObject());
            dbAdapter.close(); 

            //After save GPS coordinate it upload to backend using service
            startService(new Intent(HomeActivity.this, UploadService.class));
            Toast.makeText(HomeActivity.this, message, Toast.LENGTH_LONG).show();
        }

        public void onStatusChanged(String s, int i, Bundle b) {
            Toast.makeText(HomeActivity.this, "Provider status changed",Toast.LENGTH_LONG).show();
        }

        public void onProviderDisabled(String s) {
           Toast.makeText(HomeActivity.this,"Provider disabled by the user. GPS turned off",Toast.LENGTH_LONG).show();
        }
        public void onProviderEnabled(String s) {
          Toast.makeText(HomeActivity.this, "Provider enabled by the user. GPS turned on",Toast.LENGTH_LONG).show();
        }

    }

这是我的接收者。

    public class GpsReceiver extends BroadcastReceiver {
@Override
public void onReceive(final Context context, Intent intent) {
    int delay = 5000; // delay for 5 sec.
    //int period = 1000 *60*5; // repeat every 5min.
    int period = 30000; // repeat every 5min.

    //TO-REMOVE -TESTING PURPOSE
     Intent serviceIntent = new Intent(context,UploadService.class);
     context.startService(serviceIntent);

     if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
        Timer timer = new Timer();

        timer.scheduleAtFixedRate(new TimerTask() {
        public void run() {
            System.out.println(" Receiver done");
            Intent serviceIntent = new Intent(context,UploadService.class);
            context.startService(serviceIntent);
        }

        }, delay, period);
    }
}

}

这是我的服务。

问题是它没有去服务类。

请帮我解决这个问题...

Answer 1

我认为你的包名是不正确的清单文件

  <service android:enabled="true" android:name="com.mass.gps.service.UploadService" />

将您的服务名称指定为包名称

Answer 2

在接收器中使用它：

Intent i = new Intent();
i.setClassName("com.intelligent.locator", "com.intelligent.locator.AlarmActivity");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);

如何从broadcastReceiver调用服务方法？
