I have the following code:

wd.setUrl("http://www.cordeiroit.com.br/SOUPROGRESSO/Ctrl/ServerUsuario.php");
wd.setMethod("new-usuario");

wd.setName(campoNome.getText().toString());
wd.setCpf(campoCpf.getText().toString());
wd.setBairro(campoBairro.getText().toString());
wd.setEmail(campoEmail.getText().toString());
wd.setTelefone(campoTelefone.getText().toString());

new Thread() {
    public void run() {
        answer = HttpConnection.getSetDataWeb(wd);

        runOnUiThread(new Runnable() {
            public void run() {

                try {
                    answer = Integer.parseInt(answer) == 1 ? "Cadastro efetuado com sucesso!" : "FALHA. Não foi possível enviar!";
                    Toast.makeText(GerenciarUsuarioActivity.this, answer, Toast.LENGTH_SHORT).show();
                }
                catch (NumberFormatException e) {
                    e.printStackTrace();
                }
            }
        });
    }
};

PHP:

<?php
    /*$f = fopen('POST_DATA.txt', 'a');

    fwrite($f, 'ID: '.$id."\r\n");

    $id = uniqid( time() );

    fwrite($f, 'Nome: '.$_POST['nome']."\r\n");
    fwrite($f, 'Cpf: '.$_POST['cpf']."\r\n");
    fwrite($f, 'Bairro: '.$_POST['bairro']."\r\n");
    fwrite($f, 'E-mail: '.$_POST['email']."\r\n");
    fwrite($f, 'Telefone: '.$_POST['telefone']."\r\n\r\n");

    fclose($f);

    echo 'Dados enviados com sucesso';*/

    /*$data = array('nome' => 'felipe',
    'email' => '',
    'bairro' => '', 
    'Telefone' => '');
    print (json_encode($data));

    //echo 'nome-SPDATA-idade-SPDATA-país'
?>

How to return this data on Android?

I made the code below and returns me the following error in Httpclient when I give a system in the variable that returns http:

    Put the stacktrace, can not do much with a mistake "org.apache.http.client.methodos.HTTPPost@41088"...

  • Welcome Elipe, avoid title as "Could anyone help me?".

  • Your PHP is useless for absolutely nothing, since all of its code is within comments.

  • yes but I took the comments and the PHP code gives in the same
