Pessoal, estou tentando conectar o celular Android com um BD que ta na net…
Tenho uma página php pra passar os dados.
Página php (getAllPeopleBornAfter):
[code] <?php
mysql_connect(“localhost”,“root”,“root”);
mysql_select_db(“androider_local”);
$q=mysql_query("SELECT * FROM people WHERE birthyear>'".$_REQUEST['year']."'");
while($e=mysql_fetch_assoc($q))
$output[]=$e;
print(json_encode($output));
mysql_close();
?>[/code]
Eu consigo acessar essa página assim: http://localhost/getAllPeopleBornAfter.php, mas tem que passar o parâmetro (o ano)
Segue a classe que fiz com o Android:
[code]public class activity extends Activity {
TextView tvimc;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
CarregaTelaPrincipal();
}
public void CarregaTelaPrincipal() {
setContentView(R.layout.main);
tvimc = (TextView) findViewById(R.field.lbinf);
String result = "";
//the year data to send
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("year","1980"));
InputStream is = null;
//http post
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://localhost/getAllPeopleBornAfter.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
Log.e("log_tag", "Error in http connection "+e.toString());
}
//convert response to string
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();
result=sb.toString();
}catch(Exception e){
Log.e("log_tag", "Error converting result "+e.toString());
}
//parse json data
try{
JSONArray jArray = new JSONArray(result);
for(int i=0;i<jArray.length();i++){
JSONObject json_data = jArray.getJSONObject(i);
Log.i("log_tag","id: "+json_data.getInt("id")+
", name: "+json_data.getString("name")+
", sex: "+json_data.getInt("sex")+
", birthyear: "+json_data.getInt("birthyear")
);
}
}catch(JSONException e){
Log.e("log_tag", "Error parsing data "+e.toString());
}
}
}[/code]
Mas não ta funfando…
Onde to fazendo errado?
