我的要求是：Android的服務：如何啓動服務
我要上傳的SQLite表記錄到MS SQL server.I已經service.Normal上傳工作阿洛斯登錄後罰款（普通上傳方式，它會顯示上傳表信息列表。當用戶點擊上傳按鈕時，它會上傳&轉到下一個屏幕）。現在我想這樣做：銷售代表保存發票/付款，然後服務啓動&上傳數據在後端SQL服務器，而不影響其餘的代碼。
我不喜歡這樣的：
public class UploadService extends Service {
private static final String TAG = "UploadService";
public static final String APPURL = "http://192.168.1.213:7986/XontService";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String METHOD_NAME = "convertJSONToDataSet";
private static String SOAP_ACTION = "http://tempuri.org/IXontService/convertJSONToDataSet";
ArrayList<String> uploadFiler = new ArrayList<String>();
HashMap<Integer,String> uploadTable = new HashMap<Integer, String>();
@Override
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public void onCreate() {
Toast.makeText(this, "Upload Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
uploadUsingService();
}
@Override
public void onDestroy() {
Toast.makeText(this, "Upload Service Stopped", Toast.LENGTH_LONG).show();
Log.d(TAG, "onDestroy");
}
@Override
public void onStart(Intent intent, int startid) {
Toast.makeText(this, "Upload Service Started", Toast.LENGTH_LONG).show();
Log.d(TAG, "onStart");
}
public void uploadUsingService(){
uploadTable = getUploadTable();
if(uploadTable.size() > 0){
for (Map.Entry<Integer, String> entry : uploadTable.entrySet()) {
System.out.println("----key" + entry.getKey());
String value = entry.getValue();
if(value.equals("WMInvoiceHeader")){
getInvoiceHeader();
}
}
}
}
public void getInvoiceHeader(){
boolean serviceStatus =true;

e.printStackTrace();
}
return uploadTableMap;
}
}
在這裏，我想打電話給在onStart()uploadUsingService()方法。
這是我的調用代碼：
if(is3g ||isWifi){
startService(new Intent(this, UploadService.class));
}else if (networkType == TelephonyManager.NETWORK_TYPE_GPRS) {
if(signalStrengthInt > 10){ ....}
}
當我運行這段代碼：我得到這個onCreate()' method吐司message上傳服務創建. '在onStart（）`吐司消息不顯示。我怎麼稱呼這個。我這樣做了這部分Link
請有人幫我解決這個問題嗎？
