IntentService está congelando minha interface do usuário do aplicativo
No meu aplicativo, estou usando o Intentservice para buscar os dados do servidor e armazenar dados buscados no sqlite db local. Estou usando o 5 IntentService para buscar e preencher cinco tabelas. Os dados podem ter até 300 linhas para cada serviço de intenção. O que devo fazer?
Código IntentService:
public class SendBpRecordServer extends IntentService {
DbHelper dbHelper;
public static final String TAG="BP Service";
public JSONObject finalData;
public SendBpRecordServer() {
super("BP");
dbHelper=new DbHelper(this);
Log.i("In Constructor",TAG);
}
@Override
protected void onHandleIntent(Intent intent) {
String recName=intent.getStringExtra("nameTag");
if (recName.equals("fetch"))
{
Log.i("Send Data","Yes");
fetchDatFromServer();
ResultReceiver resultReceiver=intent.getParcelableExtra("receiverTagBP");
Log.d("BP Reseult ",resultReceiver.toString());
Bundle bun= new Bundle();
bun.putBoolean("Process_Complete_bp",true);
resultReceiver.send(2, bun);
}
else {
Log.i("Inside Service PUT BP ","Yes");
dataCollected();
}
}
private void fetchDatFromServer() {
Response.Listener listener=new Response.Listener<JSONObject>()
{
@Override
public void onResponse(JSONObject response) {
Log.i("Json Array Response", response.toString());
try
{
Boolean responseStatusCondition=response.getBoolean("success");
if (responseStatusCondition)
{
JSONArray jsonArray=response.getJSONArray("response");
Log.i("Array Size is",Integer.toString(jsonArray.length()));
for (int i=0;i<jsonArray.length();i++)
{
JSONObject childJSONObject = jsonArray.getJSONObject(i);
//Set the flag bit to 1 since data is already at server
long result=dbHelper.insertIntoBloodPressureDetails(childJSONObject.getInt("systolic"), childJSONObject.getInt("diastolic"), childJSONObject.getLong("timestamp"),1 );
// Log.i("Insertion result ",Long.toString(result));
}
Calendar c = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
c.set(Calendar.HOUR_OF_DAY, 0);
c.set(Calendar.MINUTE, 0);
c.set(Calendar.SECOND, 0);
c.set(Calendar.MILLISECOND, 0);
//This is midnight time in GMT
long unixTimeStamp = c.getTimeInMillis();
//Convert it in to Indian time System
long indianMidNightTime=unixTimeStamp-19800000;
//Log.i("Now Calculates Days","doing");
dbHelper.calculateDays(dbHelper.bpTableName, dbHelper.bpCOLUMN_days, dbHelper.bpCOLUMN_timestamp, indianMidNightTime);
}
}catch (JSONException js)

Código para chamar intentservice:
Log.i("Fetch BP Data ", SendBpRecordServer.TAG);
resultReceiverBP=new MyResultReceiver(new Handler());
resultReceiverBP.setReceiver(this);
Log.i("Bp resultreceiver ",resultReceiverBP.toString());
Intent intent2=new Intent(this,SendBpRecordServer.class);
intent2.putExtra("nameTag","fetch");
intent2.putExtra("receiverTagBP",resultReceiverBP);
startService(intent2);
e intenção me envie o código quando concluir a tarefa
No onReceiveResult .., o código de resultado é enviado pelo serviço de chamada intent e, quando a contagem chega a 5, inicia a atividade principal (embora esse truque não esteja funcionando, ou seja, iniciar a atividade principal sem concluir a tarefa atribuída ao serviço intents).
@Override
public void onReceiveResult(int resultCode, Bundle resultData) {
// TODO Auto-generated method stub
Log.d("Diabetes","received result from Service= "+resultData.getString("ServiceTag"));
// Log.d("BMI ","received result from Service= "+resultData.getString("ServiceTag"));
/* if (progressDialog.isShowing()) {
progressDialog.dismiss();
}*/
Log.i("Get Values ",Integer.toString(Constants.getValues));
if (resultCode==0 && resultData.getBoolean("Process_Complete"))
Constants.getValues++;
if (resultCode==1 && resultData.getBoolean("Process_Complete_bmi"))
Constants.getValues++;
if (resultCode==2 && resultData.getBoolean("Process_Complete_bp"))
Constants.getValues++;
if (resultCode==3 && resultData.getBoolean("Process_Complete_med_stats"))

if (progressDialog.isShowing()) {
