Witam,
IDE w jakim się poruszam to Android Studio. wcześniej bawiłem się też w AIDE na androidzie. W obu przypadkach ten sam problem, a mianowicie - po próbie nadania http request POST po kliknięciu w button aplikacja po prostu się zatrzymuje. Czy ktoś może pomóc mi w rozwiązaniu problemu?
MainActivity:
package com.example.wazniak96.app;
import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.util.ArrayList;
import java.util.List;
import org.apache.http.HttpResponse;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.graphics.Color;

import android.widget.Button;
import android.widget.TextView;
import android.view.View.OnClickListener;
public class MainActivity extends ActionBarActivity {
TextView b2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button b1 = (Button) findViewById(R.id.button);
b2 = (TextView) findViewById(R.id.hello);
OnClickListener l = new OnClickListener() {
@Override
public void onClick(View view) {
b2.setText("Wyslano! Chyba...");
makePostRequest();
}
};
b1.setOnClickListener(l);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
private void makePostRequest() {
HttpClient httpClient = new DefaultHttpClient();
// replace with your url
HttpPost httpPost = new HttpPost("mysite.net");
//Post Data
List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2);
nameValuePair.add(new BasicNameValuePair("username", "test_user"));
nameValuePair.add(new BasicNameValuePair("password", "123456789"));
//Encoding POST data
try {
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
} catch (UnsupportedEncodingException e) {
// log exception
e.printStackTrace();
}
//making POST request.
try {
HttpResponse response = httpClient.execute(httpPost);
// write response to log
b2.setText(response.toString());
} catch (ClientProtocolException e) {
// Log exception
e.printStackTrace();
} catch (IOException e) {
// Log exception
e.printStackTrace();
}
}
}
Oczywiście uprawnienia do manifestu dodane...
Pozdrowienia i z góry dzięki 🙂
