OBSERVAÇÃO :como mencionado na pergunta anterior, a string JSON fornecida precisa estar no formato correto, ou seja, ter uma chave para cada objeto (login, contas) ou tê-los em uma única matriz (entrada). Estou dando solução para ambas as opções.
Iniciante, estou fornecendo a você 2 métodos separados para que você possa lidar com a string JSON recebida, dependendo de como você a constrói:2 objetos em uma única string JSON ou 2 objetos em uma matriz JSON.
Você pode escolher sua solução :)
Experimente o código, avise-me se precisar de mais ajuda e aceite a resposta.
OPTION1:2 objetos em uma única string JSON
{
"login":{
"error":false,
"user":{
"br_code":12,
"mem_id":13,
"username":"novalyn",
"email":"[email protected]",
"created_at":"2016-07-22 09:05:21"
}
},
"accounts":{
"error":false,
"sl_summ":[
{
"sl_desc":"PA : Savings Account",
"tr_date":"2015-08-17",
"actual_balance":"483.67",
"available_balance":"483.67"
},
{
"sl_desc":"PA : Savings - Cash Bond",
"tr_date":"2015-08-28",
"actual_balance":"10129.43",
"available_balance":"10129.43"
}
]
}
}
OPTION2:2 objetos em uma única string de matriz JSON
{
"input":[
{
"error":false,
"user":{
"br_code":12,
"mem_id":13,
"username":"novalyn",
"email":"[email protected]",
"created_at":"2016-07-22 09:05:21"
}
},
{
"error":false,
"sl_summ":[
{
"sl_desc":"PA : Savings Account",
"tr_date":"2015-08-17",
"actual_balance":"483.67",
"available_balance":"483.67"
},
{

"tr_date":"2015-08-28",
"actual_balance":"10129.43",
"available_balance":"10129.43"
}

Eu não tenho acesso a todos os arquivos PHP internos que posso usar para executar seu código PHP, então substituí a maioria de todas as chamadas de função por valores codificados como compartilhados na carga de resposta de amostra. Aqui está o código para gerar objetos JSON no formato OPTION1.
Em resumo, você precisa adicionar ["login"] e ["accounts"] antes de todos os subatributos em $response para que eles sejam agrupados no objeto JSON correto e você tenha dois objetos JSON que podem ser analisados acima código compartilhado android.
<?php

$br_response = array("error" => FALSE);
$sl_response["error"] = FALSE;
$sl_response["sl_summ"] = array();
$arclass = "13";

$accintreceivable = "21";
// user is found
$response["login"]["error"] = FALSE;
