Androidアプリを使用してサーバーにデータを送信するために使用されると思われる次のコードがありますが、「残念ながらアプリ名が停止されました」というエラー状態が発生し続けます
私の活動コードは:
public class SendDataToServerActivity extends Activity {
/** Called when the activity is first created. */
Button sendButton;
EditText msgTextField;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// make message text field object
msgTextField = (EditText) findViewById(R.id.msgTextField);
// make send button object
sendButton = (Button) findViewById(R.id.sendButton);
sendButton.setOnClickListener(new Button.OnClickListener(){
//perform your action here
public void onClick(View v){
String msg = msgTextField.getText().toString();
// make sure the fields are not empty
if (msg.length()>0)
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://98.131.137.4/husam.php");
try {
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("id", "12345"));
nameValuePairs.add(new BasicNameValuePair("message", msg));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
httpclient.execute(httppost);
msgTextField.setText("");
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
}
else
{
// display message if text fields are empty
Toast.makeText(getBaseContext(),"All field are required",Toast.LENGTH_SHORT).show();
}
}
});
}
}
私のログは次のとおりです。

アプリをデバッグするとエラーや警告がないという事実を知っているので、ここで何が間違っているのかを教えてくれる人はいますか
よろしく
