i am using this JSONParser.java:
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
// constructor
public JSONParser() {
}
public JSONObject getJSONFromUrl(String url, List<NameValuePair> params) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
Log.e("JSON", json);
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}
it is working fine for my other requests. Now my php-file sending an array. How I convert it to an Jarray or directly in an ArrayList, which i can use in my app?
the array (2 items) looks like:
03-15 20:40:16.667: E/JSON(26100): [{"ean":"8029694000","name":"KRINGS-VERBAU","betriebsdatenalt":"412"},{"ean":"8026786937","name":"KOMPRESSOR FAHR 5,3 M3 XAS97DDG","betriebsdatenalt":"0"}]

If you have an array
JSONArray myArray=new JSONArray(string)
now loop through the array and get the objects like
ArrayList<JSONObject> yourObjects=new ArrayList<JSONObject>();
for(int i=0;i<myArray.length();i++){
yourObjects.add(myArray.getJSONObject(i))
}
also check every time if its a object or array you are getting like if
JSONObject obj=new JSONObject(string from server);
if(obj==null){
JSONArray array=new JSONArray(string from server)
}
