I get this message:
"The type of the expression must be an array type but it resolved to
JSONArray"
It happens on this line in the below java code:
JSONObject unit = units[i];
units[i] should be holding { "id":3001, "markers": [...]}.
I have json data that looks like this:
result = {
"status":200,
"error":null,
"data":
{
"units":
[
{
"id":3001,
"markers":
[
{"latitude":"28.92977431","longitude":"-82.01933333","address":"unknown"},
{"latitude":"22.92977431","longitude":"-42.01933333","address":"unknown"},
{"latitude":"33.92977431","longitude":"-66.01933333","address":"unknown"}
]
}
]
}
}
Here's my java code:
Map<String,String> reportData1 = new HashMap<String, String>();
List<Map<String , String>> reportData = new
ArrayList<Map<String,String>>();
String result = QWebservice.getWebResource(
WEBSERVICE,
query);
try {
JSONObject jsonResult = new JSONObject(result);
JSONObject data = jsonResult.getJSONObject("data");
JSONArray units = data.getJSONArray("units");
for(int i = 0 ; i < units.length(); i++){
JSONObject unit = units[i];
JSONObject reports =
unit.getJSONArray("markers");
for(int j = 0; j < reports.length(); j++){
report = reports[j];
Iterator iter = report.keys();
while(iter.hasNext()){
String key =
(String)iter.next();
if(key.equals("latitude")){
reportData1.put("latitude", report.getString(key));
reportData.add(j,reportData1);
}
if(key.equals("longitude")){
reportData1.put("longitude", report.getString(key));
reportData.add(j,reportData1);
}
if(key.equals("address")){
reportData1.put("address", report.getString(key));
reportData.add(j,reportData1);
}
}
}
}
} catch (JSONException e) {
Log.e("log_tag", "Error parsing data " + e.toString());
}
