android - Androidのバックグラウンドで複数のサービスを呼び出す

Question

Androidアプリのプロジェクトでは、バックグラウンドで複数のサービスを呼び出す必要があります。各サービスでは、個別のWebサービスを呼び出してデータを取得し、ローカルのsqliteデータベースで処理する必要があります。各サービスを個別に呼び出すことができ、ローカルデータベースでその結果を操作できます。ただし、すべてのサービスを順番に呼び出すことはできません。私のコードは以下の通りです：

@Override
    public void onStart(Intent intent, int startid) {
        Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
        Timer timer = new Timer();

        final SyncTableUsers syncUserObj = new SyncTableUsers(LocalService.this);
        final SyncTableVehicles syncVehicleObj = new SyncTableVehicles(this);
        final SyncTableLicenses syncLicenseObj = new SyncTableLicenses(this);
        final SyncTableTags syncTagObj = new SyncTableTags(this);
        final SyncTableTagMappings syncTagMapObj = new SyncTableTagMappings(this);
        final SyncTableAddresses syncAddressObj = new SyncTableAddresses(this);
        final SyncTableDispatches syncDispatchObj = new SyncTableDispatches(this);
        final SyncEditCompany syncCompanyObj = new SyncEditCompany(LocalService.this);
        final SyncEditVehicle syncEditVehicleObj = new SyncEditVehicle(LocalService.this);
        final SyncEditUser syncEditUserObj = new SyncEditUser(this);
        final SyncVehicleLog vLogObj = new SyncVehicleLog(LocalService.this);
        TimerTask timerTask = new TimerTask() {

            @Override
            public void run() {
                        syncUserObj.syncUserData();
                        syncVehicleObj.syncVehicleData();
                        syncLicenseObj.syncLicensesData();
                        syncTagObj.syncTagData();
                        syncTagMapObj.syncTagMappingData();
                        syncAddressObj.syncAddressData();
                        syncDispatchObj.syncDispatchData();
                        syncCompanyObj.syncCompanyData();
                        syncEditVehicleObj.syncVehicleData();
                        syncEditUserObj.syncUserData();
                        Log.i("TAG", "LogId After insert values ");
                }
            }
        };
        timer.scheduleAtFixedRate(timerTask, 10000, 180000);  call after every
                                                             3 minute
        super.onStart(intent, startid);

syncUserDataは、Webサービスを呼び出すメソッドです。

AsyncTaskソリューションを利用することをお勧めします。これは、リクエストやその他のバックグラウンドタスクを実行し、AsyncTaskを使用する必要がある最新のOSバージョンを備えたデバイスを使用してWebサービスを呼び出す簡単で簡単な方法です。

リクエストの実行中に何らかのプログレスバーを表示する必要がある場合は、onProgressUpdateなどを実装するのも簡単です。

private class YourTask extends AsyncTask<URL, Integer, Long> {
 protected Long doInBackground(URL... urls) {
    //call your methods from here
         //publish yor progress here..
        publishProgress((int) ((i / (float) count) * 100));
 }

 protected void onProgressUpdate(Integer... progress) {
     setProgressPercent(progress[0]);
 }

 protected void onPostExecute(Long result) {
    //action after execution success or not
 }
}

インテントサービスを使用して、タスクを順番に実行します。詳細については、以下のリンクを確認してください
