android解析json异常处理,Android的JSON异常而解析

我试图分析我的Android应用程序中的JSON(进一步我将填补与内容列表视图)，所以我做了这个类：Android的JSON异常而解析

public class MainActivity extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

new ReadJSONFeedTask().execute("http://10.14.182.253/viztonjob/update.php?updatedAt=01011970");

}

public String readJSONFeed(String URL) {

StringBuilder stringBuilder = new StringBuilder();

HttpClient client = new DefaultHttpClient();

HttpGet httpGet = new HttpGet(URL);

try {

HttpResponse response = client.execute(httpGet);

StatusLine statusLine = response.getStatusLine();

int statusCode = statusLine.getStatusCode();

if (statusCode == 200) {

HttpEntity entity = response.getEntity();

InputStream content = entity.getContent();

BufferedReader reader = new BufferedReader(

new InputStreamReader(content));

String line;

while ((line = reader.readLine()) != null) {

stringBuilder.append(line);

}

} else {

Log.e("JSON", "Failed to download file");

}

} catch (ClientProtocolException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

return stringBuilder.toString();

}

private class ReadJSONFeedTask extends AsyncTask {

private final ProgressDialog pd = new ProgressDialog(MainActivity.this);

protected String doInBackground(String... urls) {

return readJSONFeed(urls[0]);

}

protected void onPreExecute() {

this.pd.setMessage("Chargement de la liste des métiers ...");

this.pd.show();

}

protected void onPostExecute(String result) {

pd.dismiss();

try {

JSONArray jsonArray = new JSONArray(result);

Log.i("JSON",

"Number of surveys in feed: " + jsonArray.length());

for (int i = 0; i < jsonArray.length(); i++) {

JSONObject jsonObject = jsonArray.getJSONObject(i);

Toast.makeText(

getBaseContext(),

jsonObject.getString("metiers") + " - "

+ jsonObject.getString("categorie"),

Toast.LENGTH_SHORT).show();

}

} catch (Exception e) {

e.printStackTrace();

}

}

}

}

所以我m使用AsyncTask来恢复我的数据，然后我尝试在Toast中显示它。

当我启动我的申请，我得到我的ProgressDialog后关闭以下警告：

，并没有任何敬酒。我试图验证JSON，并明显没有错误。所以我想知道你是否知道它可以从哪里来。
