因此​​，这里是code：

 公共类JSONParser扩展的AsyncTask＆LT;虚空，虚空，布尔＆GT; {

静态的InputStream是= NULL;
静态的JSONObject jObj = NULL;
静态JSON字符串=;

//构造
公共JSONParser（）{

}

公众的JSONObject getJSONFromUrl（字符串URL）{

    //使HTTP请求
    尝试 {

解决方案

[...] 意味着它应该是一个 JSONArray 和 {...} 意味着它应该是一个的JSONObject 。

因此​​：

 尝试{
        JSONArray jObj =新JSONArray（JSON）;
    }赶上（JSONException E）{
        Log.e（JSON解析器，错误分析数据+ e.toString（））;
    }
 

Got stuck at this error:

3169-3190/com.meisolsson.app E/JSON Parser﹕ Error parsing data org.json.JSONException: Value [{"type":0,"can_see_custom_stories":true,"display":"","name":"jenniaim"},{"type":0,"can_see_custom_stories":true,"display":"","name":"lucasgardebrand"},{"type":0,"can_see_custom_stories":true,"display":"","name":"herr_anderzzon"},{"type":0,"can_see_custom_stories":true,"display":"","name":"chrillebile"},{"type":0,"can_see_custom_stories":true,"display":"","name":"meisolsson"},{"type":0,"can_see_custom_stories":true,"display":"","name":"sakanapanda"},{"type":0,"can_see_custom_stories":true,"display":"Team Snapchat","name":"teamsnapchat"},{"type":0,"can_see_custom_stories":true,"display":"","name":"fabianlindfors"},{"type":0,"can_see_custom_stories":true,"display":"Katja","name":"katjaawesome"},{"type":0,"can_see_custom_stories":true,"display":"","name":"swimkey"},{"type":1,"can_see_custom_stories":true,"display":"","name":"agnesholmberg"}] of type org.json.JSONArray cannot be converted to JSONObject

So here is the code:

public class JSONParser extends AsyncTask<Void, Void, Boolean> {

static InputStream is = null;
static JSONObject jObj = null;
static String json = "";

// constructor
public JSONParser() {

}

public JSONObject getJSONFromUrl(String url) {

    // Making HTTP request
    try {
        // defaultHttpClient
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);

        ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("username", LoginActivity.Suser));
        nameValuePairs.add(new BasicNameValuePair("password", LoginActivity.Spass));
        httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        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();
    } 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;

}
@Override
protected Boolean doInBackground(Void... params) {
    getJSONFromUrl("http://flapplabs.se/development/snapchat/friends.php");
    return null;
}
}

解决方案

[..] means it should be an JSONArray and {..} means it should be a JSONObject.

Therefore:

try {
        JSONArray jObj = new JSONArray(json);
    } catch (JSONException e) {
        Log.e("JSON Parser", "Error parsing data " + e.toString());
    }
