Hello I am receiving a JSON file from an URL in an Android device. I have no idea why I am getting just the first character of the JSON, this is a "{" instead of
{"status":"OK","num_results":5,"results":[{"id":1,"title":"Apartamentos Campus"
,
Then is.available() is returning 1 all the time.
The funny thing is that if I use in another device it receives everything.
I am using the wifi to connect.
And the output that I am getting is:
03-11 13:12:17.377: VERBOSE/Mixare(15816): attemps: 1
03-11 13:12:17.382: VERBOSE/Mixare(15816): is.available(): 1
03-11 13:12:17.462: VERBOSE/Mixare(15816): attemps: 1
03-11 13:12:17.482: VERBOSE/Mixare(15816): is.available(): 1
03-11 13:12:19.417: VERBOSE/Mixare(15816): attemps: 2
03-11 13:12:19.417: VERBOSE/Mixare(15816): is.available(): 1 ...
And this is the code:
public InputStream getHttpGETInputStream(String urlStr, int attemps) throws Exception {
URL u = new URL(urlStr);
InputStream is = null;
try{
URLConnection uc = u.openConnection();
is = uc.getInputStream();
}
catch(Exception e){
Log.v(MixView.TAG, "Excepcion leyendo inputStream: "+e.getMessage());
}
Log.v(MixView.TAG, "attemps: "+attemps);
Log.v开发者_运维技巧(MixView.TAG, "is.available(): "+is.available());
if(is.available() < 50 && attemps < 6){
try {
Thread.sleep(2000);//para y lo vuelve a intentar descargar
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
attemps++;
is.close();
return getHttpGETInputStream(urlStr,attemps);
}
return is;
}
I guess, You are reading the content in wrong way. Please use following code:
public static final byte[] getBytes(URLConnection conn ) throws IOException {
final InputStream inputStream = conn.getInputStream();
final ByteArrayOutputStream baos = new ByteArrayOutputStream();
final byte[] b = new byte[256];
int rv = 0;
while ( ( rv = inputStream.read(b) ) != -1 ) baos.write(b, 0, rv);
try { inputStream.close(); } catch ( Exception e ) {};
try {
final HttpURLConnection httpConn = (HttpURLConnection)conn;
httpConn.disconnect();
}
catch ( Exception e ) {};
final byte[] bytes = baos.toByteArray();
baos.close();
return bytes;
}
public static final String getResponse(URLConnection conn) throws IOException {
final byte[] bytes = getBytes(conn);
final String response = new String(bytes,"UTF-8");
return response;
}
...
final JSONObject responseObj = new JSONObject(getResponse(your_url_connection));
