Retorno Json Cakephp null para o android

Ao passar os dados no navegador desta forma:

http://127.0.0.1/system/pages/login?json={%22Pass%22:%22123456%22,%22RA%22:%[telefone removido]%22}.json Obtenho o seguinte retorno: {"User":{"id":"1","status_id":"1","name":"Felipe","RA":"242252014","email":"[email removido]","password":"123456","data_cancel":null},"Status":{"id":"1","name":"Ativo"}}

Código Cakephp:

public function login(){
	$this->autoRender = false;
    $this->response->type('application/json');
    $this->layout = null;
	
	$dados = json_decode(str_replace(".json", "", $_REQUEST["json"]), true);

	$ra = $dados["RA"];
	$senha = $dados["Pass"];
	
	$usuario = $this->User->find("first",
             ["conditions" => ["User.RA" => $ra, "User.password" => $senha ] ]);
	
	$retorno = array($usuario);
	
	header('Content-type: application/json');
	echo json_encode($retorno);			
	
}

Pego os dados da seguinte forma no android:

InputStream in = new BufferedInputStream(conn.getInputStream());

reader = new BufferedReader(new InputStreamReader(in));
String line = "";
StringBuffer buffer = new StringBuffer();

while ((line = reader.readLine()) != null){
    buffer.append(line);
}
JSONArray jresp = null;
jresp = new JSONArray(buffer.toString());

Como resolver?

Luis primeiramente obrigado pela ajuda já estava perdido aqui.

public void onClick(View v) {
    if(v.getId() == R.id.btnEntrar){
        RA = AlunoRA.getText().toString();
        Senha = AlunoSenha.getText().toString();


        final JSONObject obj = new JSONObject();

        try {
            obj.put("RA", RA);
            obj.put("Pass", Senha);
        } catch (JSONException e) {
            e.printStackTrace();
        }

        this.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                String caminho = "http://10.0.2.2/system/pages/login";
                HttpURLConnection conn = null;
                BufferedReader reader = null;
                try{
                    URL urlConection = new URL(caminho);
                    conn = (HttpURLConnection) urlConection.openConnection();
                    conn.setDoOutput(true);
                    conn.setRequestMethod("POST");


                    PrintStream ps = new PrintStream(conn.getOutputStream());
                    ps.printf("json", obj.toString());

                    conn.connect();


                    String resposta = new Scanner(conn.getInputStream()).next();
                    /*JSONArray arr = new JSONArray(new Scanner(conn.getInputStream()).next());
                    JSONObject resp = new JSONObject(resposta);

                    InputStream in = new BufferedInputStream(conn.getInputStream());

                    reader = new BufferedReader(new InputStreamReader(in));
                    String line = "";
                    StringBuffer buffer = new StringBuffer();

                    while ((line = reader.readLine()) != null){
                        buffer.append(line);
                    }
                    JSONArray jresp = null;
                    jresp = new JSONArray(buffer.toString());

                    //JSONObject jo = new JSONObject(jresp.toString());


                    Log.d("JSON", obj.toString());
                    Log.d("resposta", buffer.toString());


            /*
                    if(resposta.equals("1")){
                        Intent abreHome = new Intent(Login.this, Home.class);
                        startActivity(abreHome);
                    } else {
                        Toast.makeText(Login.this, "Ops houve um erro. Tente novamente", Toast.LENGTH_SHORT).show();
                       // Log.d("retorno", resp.toString());
                    }*/


                } catch (MalformedURLException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                } catch (JSONException e) {
                    e.printStackTrace();
                }

            }
        });

    }

Esse código acima corresponde a todo o meu onClick.

Quanto a esse é referente de toda a classe
