Hi.
I implemented a process that do multiple web service request to fill the
tables one by one, but I'm having some problems for example:
- The same process on my Razr(Android 4.0.4) the process completed
normally, but in a smartphone with Android(2.2) for example, I get errors
like 'SocketTimeout', connections problems and exceptions (FutureTask).
The process:
on my doInBackground I'm calling all the requests:
@Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
Cliente cliente = new Cliente();
cliente.setWsRepresentante(getSharedPreferences("PREFS_PRIVATE",
MODE_PRIVATE).getInt("representante", 0));
cliente.importarDados();
TabelaPreco tabelaPreco = new TabelaPreco();
tabelaPreco.setWsRepresentante(getSharedPreferences("PREFS_PRIVATE",
MODE_PRIVATE).getInt("representante", 0));
tabelaPreco.importarDados();
ClienteEndereco clienteEndereco = new ClienteEndereco();
clienteEndereco.setWsRepresentante(getSharedPreferences("PREFS_PRIVATE",
MODE_PRIVATE).getInt("representante", 0));
clienteEndereco.importarDados();
Comprador comprador = new Comprador();
comprador.setWsRepresentante(getSharedPreferences("PREFS_PRIVATE",
MODE_PRIVATE).getInt("representante", 0));
comprador.importarDados();
ProdutoPreco produtoPreco = new ProdutoPreco();
produtoPreco.setWsRepresentante(getSharedPreferences("PREFS_PRIVATE",
MODE_PRIVATE).getInt("representante", 0));
produtoPreco.importarDados();
Embalagem embalagem = new Embalagem();
embalagem.setWsRepresentante(getSharedPreferences("PREFS_PRIVATE",
MODE_PRIVATE).getInt("representante", 0));
embalagem.importarDados();
Produto produto = new Produto();
produto.setWsRepresentante(getSharedPreferences("PREFS_PRIVATE",
MODE_PRIVATE).getInt("representante", 0));
produto.importarDados();
Grupo grupo = new Grupo();
grupo.setWsRepresentante(getSharedPreferences("PREFS_PRIVATE",
MODE_PRIVATE).getInt("representante", 0));
grupo.importarDados();
FormaPagamento formaPagamento = new FormaPagamento();
formaPagamento.setWsRepresentante(getSharedPreferences("PREFS_PRIVATE",
MODE_PRIVATE).getInt("representante", 0));
formaPagamento.importarDados();
Cidade cidade = new Cidade();
cidade.setWsRepresentante(getSharedPreferences("PREFS_PRIVATE",
MODE_PRIVATE).getInt("representante", 0));
cidade.importarDados();
return null;
}
This importarDados() call the super method from each class that execute
this process that fill the table with the results:
DataBase = new
DadosBD(Singleton.getContextoAplicacao());
SoapObject request = new SoapObject(this.getWsNameSpace(),
this.getWsNomeMetodo());
request.addProperty("representante", WsRepresentante);
SoapSerializationEnvelope envelope = new
SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.implicitTypes = false;
envelope.setOutputSoapObject(request);
HttpTransportSE httpTransport = new HttpTransportSE(this.getWsUrl());
httpTransport.call(this.getWsNameSpace() + "" + this.getWsNomeMetodo(),
envelope);
SoapObject result = (SoapObject) envelope.getResponse();
if (result != null) {
int resultCount = result.getPropertyCount();
if(resultCount > 0){
SoapObject objResult = new SoapObject();
SoapObject objSoap = new SoapObject();
objResult = (SoapObject) result.getProperty(1);
if(objResult.getPropertyCount() > 0){
objSoap = (SoapObject) objResult.getProperty(0);
int propertyResultCount = objSoap.getPropertyCount();
if (propertyResultCount > 0){
DataBase.BeginTransaction();
SQLiteStatement stmtInsert =
DataBase.getDataBase().compileStatement(DataBase.ExecInsertBuilder(Tabela,
TabelaColunaComposta));
SQLiteStatement stmtSelect =
DataBase.getDataBase().compileStatement(DataBase.ExecSelectBuilder(false,
Tabela, TabelaSelecaoArgumentos, TabelaSelecao, TabelaGroupBy,
TabelaHaving, TabelaOrderBy, "1"));
SQLiteStatement stmtUpdate =
DataBase.getDataBase().compileStatement(DataBase.ExecUpdateBuilder(Tabela,
TabelaColunaComposta, TabelaWhereArgumentos));
this.Dados = new ContentValues();
for (int currentProperty = 0; currentProperty <
propertyResultCount; currentProperty++) {
SoapObject obj = (SoapObject)
objSoap.getProperty(currentProperty);
int attributeResultCount = obj.getPropertyCount();
for(int index = 0; index < attributeResultCount;
index++){
PropertyInfo pi = new PropertyInfo();
obj.getPropertyInfo(index, pi);
stmtInsert.bindString(index + 1,
((pi.getValue().toString().equals("anyType{}")?(""):(pi.getValue().toString()))));
stmtUpdate.bindString(index + 1,
((pi.getValue().toString().equals("anyType{}")?(""):(pi.getValue().toString()))));
this.Dados.put(pi.name.toString(),
((pi.getValue().toString().equals("anyType{}")?(""):(pi.getValue().toString()))));
}
for (int i = 0; i < this.getCamposPK().length; i++)
{
stmtSelect.bindString(i + 1,
this.Dados.get(CamposPK[i].toString()).toString());
}
if(!(stmtSelect.simpleQueryForLong()==1)){
stmtInsert.executeInsert();
}else{
stmtUpdate.execute();
}
}
DataBase.SetTransaction();
DataBase.EndTransaction();
}
}
}
}
*How can I implement this process using AsyncTask? I need to create one
AsyncTask to each class?*
This requests doesn't need to be executed paralelly...
*How can I improve the security of this process?*
*
*
Thanks in advance.
