私はAndroidの初心者で、いくつかの情報をphpスクリプトに投稿するアプリを開発していますが、例外が多すぎます。
これが私のコードです:
package com.example.testapp;
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import android.content.Context;
import android.os.AsyncTask;
import android.widget.ProgressBar;
import android.widget.Toast;
public class HttpTraitement extends AsyncTask<HttpClient, Integer, HttpResponse> {
private Context context;
public HttpTraitement (Context context)
{
this.context = context;
}
@Override
protected HttpResponse doInBackground(HttpClient... params) {
// TODO Auto-generated method stub
HttpResponse response = null;
params[0] = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://namedomain/test.php");
try {
response = params[0].execute(httppost);
} catch (ClientProtocolException e) {
Toast.makeText(this.context, "Caught ClientProtocolException", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
Toast.makeText(this.context, "Caught IOException", Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Toast.makeText(this.context, "Exception", Toast.LENGTH_SHORT).show();
}
return response;
}
}
