Я знаю, что этот вопрос задавался много раз, но все остальные темы нея не могу решить мою проблемуЯ не вижу ничего плохого в моем коде. Может быть, я что-то здесь упустил, кто-нибудь может мне помочь?

Код для Службы намерений:

package Services;

import android.app.IntentService;
import android.content.Intent;
import android.widget.Toast;

public class WifiSearchService extends IntentService {

  /** 
   * A constructor is required, and must call the super IntentService(String)
   * constructor with a name for the worker thread.
   */
  public WifiSearchService() {
      super("WifiSearchService");
  }

  @Override
  public int onStartCommand(Intent intent, int flags, int startId) {
      Toast.makeText(this, "service starting", Toast.LENGTH_SHORT).show();
      return super.onStartCommand(intent,flags,startId);
  }

  /**
   * The IntentService calls this method from the default worker thread with
   * the intent that started the service. When this method returns, IntentService
   * stops the service, as appropriate.
   */
  @Override
  protected void onHandleIntent(Intent intent) {
      // Normally we would do some work here, like download a file.
  // For our sample, we just sleep for 5 seconds.
      long endTime = System.currentTimeMillis() + 5*1000;
      while (System.currentTimeMillis() < endTime) {
          synchronized (this) {
              try {
                  wait(endTime - System.currentTimeMillis());
              } catch (Exception e) {
              }
