私はこのコードをに持っていますAsyncTask
:
try
{
Log.d("API", "URL: "+URL.trim());
StringBuilder builder = new StringBuilder();
HttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(new URI(URL));
httpGet.setHeader("Accept","application/json");
httpGet.setHeader("Content-Type","application/json");
Log.d("API", "URL Host: "+httpGet.getURI().getHost());
Log.d("API", "URL Path: "+httpGet.getURI().getPath());
Log.d("API", "URL: "+URL.trim());
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)
{
builder.append(line);
}
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("id","2"));
if ( builder.toString().length()>0)
{
Log.v("API", builder.toString());
}
else
{
Log.e("API", "Respuesta vacia");
}
}
else
{
Log.e("API", "Status code != 200");
}
}
catch(Exception e)
{
e.printStackTrace();
Log.e("API", "Error >> "+e.getMessage());
}
これが私のマニフェストです:

どうもありがとう!!このエラーの一般的な理由は " http://
" が含まれていないことですが、私はそうしています!
HttpGet httpGet = new HttpGet(URL);も試しました。同じ URL ですが、post と put があります。
