PHPとmysqlに接続してAndroidログインを作成しました。プログラムを実行して正しいメールアドレスとパスワードを入力するたびに、EditTextにandroid.os.NetworkOnMainExceptionと表示されます。そのためのコードは何も起こりません。コーディングを間違えたのですか、それとも何かが足りないのですか。さて、これは私のコードの人です。
アンドロイド：
**
public class LoginActivity extends Activity {
/** Called when the activity is first created. */
EditText inputEmail ;
EditText inputPassword ;
Button btnLogin ;
public void validation()
{
if(inputEmail.getText().toString().equals("") || inputPassword.getText().toString().equals(""))
{
Toast.makeText( getApplicationContext(),"Fill Empty Fields",Toast.LENGTH_SHORT ).show();
}
else
{
connectphp();
}
}
public void connectphp()
{
// TODO Auto-generated method stub
ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();
postParameters.add(new BasicNameValuePair("eadd", inputEmail.getText().toString()));
postParameters.add(new BasicNameValuePair("password", inputPassword.getText().toString()));
//Passing Parameter to the php web service for authentication
//String valid = "1";
String response = null;
try {
response = CustomHttpClient.executeHttpPost("http://10.0.2.2:8080/TheCalling/log_in.php", postParameters); //Enter Your remote PHP,ASP, Servlet file link
String res=response.toString();
res = res.trim();
res= res.replaceAll("\\s+","");
//error.setText(res);
if(res.equals("1"))
{
Toast.makeText( getApplicationContext(),"Correct Username or Password",Toast.LENGTH_SHORT ).show();
Intent i = new Intent(LoginActivity.this,MainMenu.class);
startActivity(i);
}
else
if(res.equals("0"))
{
Toast.makeText( getApplicationContext(),"Sorry!! Incorrect Username or Password",Toast.LENGTH_SHORT ).show();
}
} catch (Exception e) {
inputEmail.setText(e.toString());
}}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
inputEmail = (EditText)findViewById(R.id.inputEmail);
inputPassword = (EditText)findViewById(R.id.inputPassword);
btnLogin = (Button)findViewById(R.id.btnLogin);
btnLogin.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
validation();
//(This is to check empty fields)
}
});
}}

ちなみに、このコードはここからスタックオーバーフローでもありました。
CustomHttpClient
**
public class CustomHttpClient {
/** The time it takes for our client to timeout */
public static final int HTTP_TIMEOUT = 30 * 1000; // milliseconds
/** Single instance of our HttpClient */
private static HttpClient mHttpClient;

*
* @return an HttpClient object with connection parameters set
*/
private static HttpClient getHttpClient() {
if (mHttpClient == null) {

final HttpParams params = mHttpClient.getParams();
HttpConnectionParams.setConnectionTimeout(params, HTTP_TIMEOUT);
HttpConnectionParams.setSoTimeout(params, HTTP_TIMEOUT);
ConnManagerParams.setTimeout(params, HTTP_TIMEOUT);
}
return mHttpClient;
}

public static String executeHttpPost(String url, ArrayList<NameValuePair> postParameters) throws Exception {
BufferedReader in = null;
try {
HttpClient client = getHttpClient();
HttpPost request = new HttpPost(url);
UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(postParameters);
request.setEntity(formEntity);
HttpResponse response = client.execute(request);
in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
StringBuffer sb = new StringBuffer("");
String line = "";
String NL = System.getProperty("line.separator");
while ((line = in.readLine()) != null) {
sb.append(line + NL);
}
in.close();
String result = sb.toString();
return result;
} finally {

try {

} catch (IOException e) {
e.printStackTrace();
}

}
}
/**

request.setURI(new URI(url));
HttpResponse response = client.execute(request);

}
}

そして私のPHPコード。
**
<?php
include("db_config.php");
$eadd=addslashes($_POST['eadd']);
$password=addslashes($_POST['password']);
$sql="SELECT * FROM users WHERE eadd='$eadd' and password='$password'";
$result=mysql_query($sql);
$row=mysql_fetch_array($result);
$count=mysql_num_rows($result);
if($count==1)
{
echo "1";
//(If result found send 1 to android)
}
else
{
echo "0";
//(If result not found send o to android)
}
?>
