JSON Error: Unterminated object on valid json text - php

Question

I'm having a problem with JSON. On my webspace I'm hosting a php file which converts a mysql request into JSON Format. Then a android device reads that JSON File and processes the data (temperature and humidity) in a graph.
PHP-Code:
<?php
include("connect.php");
// SQL Query abschicken
$result = mysql_query("SELECT * FROM classpidb ORDER BY ID DESC LIMIT 1000");
//Schleife bis alle Eintragungen in Array gespeichert
$listenArray["Liste"] = array();
while($row = mysql_fetch_array($result)) {
$listeneintrag = array();
$listeneintrag["ID"] = $row["ID"];
$listeneintrag["Time"] = $row["Time"];
$listeneintrag["Temp"] = $row["Temp"];
$listeneintrag["Humi"] = $row["Humi"];
array_push($listenArray["Liste"], $listeneintrag);
}
//Ausgabe im JSON Format
$listenArray["Status"] = ["0","Select erfolgreich"];
echo json_encode($listenArray);
//Verbindung trennen.
mysql_close($verbindung);
?>
JSON-Parsing in Android (result is the JSON-File read as string):
JSONObject jsonErgebnis = new JSONObject(result);
JSONArray statusArray = jsonErgebnis.getJSONArray("Status");
int status = statusArray.getInt(0);
if(status == 0)
{
JSONArray datenArray = jsonErgebnis.getJSONArray("Liste");
//for (int i = 0; i < datenArray.length(); i++) {
for (int i = datenArray.length() - 1; i >= 0; i--) {
JSONObject einzelsatz = datenArray.getJSONObject(i);
...
firstdatatemp.addXValue(einzelsatz.getString("Time"));
firstdatatemp.addEntry(new Entry((float) einzelsatz.getDouble("Temp"), set.getEntryCount()), 0);
...
// add a new x-value first
firstdatahumi.addXValue(einzelsatz.getString("Time"));
firstdatahumi.addEntry(new Entry((float) einzelsatz.getDouble("Humi"), set.getEntryCount()), 0);
}
}
If i use SELECT * FROM classpidb ORDER BY ID DESC LIMIT 100 it works fine. If i use 1000 instead of 100 I always get "Unterminated object at character ..." error. CodeBeautifier says my JSON text is valid.

Found the solution to the problem:
Android didn't finish reading the full php response, so I replaced the buggy code for Reading the response with
BufferedReader r = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuilder total = new StringBuilder();
String line;
while ((line = r.readLine()) != null) {
total.append(line);
}
