从Android应用程序向服务器发送数据时拒绝连接

时间：2015-01-26 16:22:31

标签： java android phpmyadmin

我是Android应用程序开发的新手，我想发送三个参数Latitude， 经度和Bimari（我在提到 我的代码如下）通过互联网到phpMyAdmin服务器。 问题是从选择bimari后 微调器，当我点击发送按钮我的应用程序崩溃。 我的服务器端工作正常。任何人都可以 请告诉我为什么我无法将数据发送到服务器？

非常感谢您的阅读！

MainActivity.java如下： - 

public final static String EXTRA_MESSAGE = "com.example.sushma.myfirstapp.MESSAGE";


String nn, nn1, nn2, nn3, nn4, nn5, nnf;  // used to make URL
String sss1, sss2;  // used to convert lat and long to string
String s; // used to save bimari as string

double lat, lng;
LocationManager lm;

String provider;
Location l;
private View view;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    lm = (LocationManager)this.getSystemService(Context.LOCATION_SERVICE);
    Criteria c = new Criteria();
    provider = lm.getBestProvider(c, false);
    l = lm.getLastKnownLocation(provider);

    if (l != null) {

     //get latitude and longitude of the location
     lng = l.getLongitude();
     lat = l.getLatitude();

     } else {
    System.out.println("No lat/long");

    }

    {


        LinearLayout l1 = new LinearLayout(this);
        l1.setBackgroundResource(R.drawable.ambulance);
        setContentView(R.layout.activity_main);
    }
}


public void ongobuttonclick(View view) {
    this.view = view;

    Spinner sp = (Spinner) findViewById(R.id.problems);

    s = sp.getSelectedItem().toString();
    sss1 = String.valueOf(lng);
    sss2 = String.valueOf(lat);

    nn = "http://192.168.2.8/tech/new_predict.php?Latitude=";
    nn1 = sss2;
    nn2 = "&Longitude=";
    nn3 = sss1;
    nn4 = "&Bimari=";
    nn5 = s;

    nnf = nn + nn1 + nn2 + nn3 + nn4 + nn5;

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httPost = new HttpPost(nnf);
    System.out.println(nnf);
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                httpclient.execute(httPost);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }).start();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override

    // Handle action bar item clicks here. The action bar will

您尝试在UI线程中执行httpclient.execute(httPost);方法。你不能做这个。

您可以使用AsyncTask来解决此问题。

public void ongobuttonclick(View view) {

     ...
    //your code 

    //use AsyncTask if you  want ot inform ui thread
     final HttpClient httpclient = new DefaultHttpClient();
    final HttpPost httPost = new HttpPost(nnf);

    new AsyncTask<HttpPost, Void, HttpResponse>() {
        //YourParams, YourProgress, YourResult can be Void
        @Override
        protected HttpResponse doInBackground(HttpPost... params) {
            HttpResponse response = null;
            try {
               response = httpclient.execute(params[0]);
            } catch (IOException e) {
                e.printStackTrace();
            }
            return response;
        }

        @Override
        protected void onPostExecute(HttpResponse response) {
            if(response != null){
                //do sth in UI thread
            }
        }
    }.execute(httPost);

    //or in new thread if you doesn't want ot inform ui thread
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                httpclient.execute(httPost);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }).start();
}
