我的文件上传到android中的php服务器有什么问题？

Question

我正在eclipse中开发和应用，它将一个简单的txt文件上传到php服务器。我的问题是，当我尝试调试它时，eclipse透视图会更改并写入：

我的代码是：

    package com.example.tryyy;

import java.io.File;
import java.io.FileInputStream;

import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.InputStreamEntity;
import org.apache.http.impl.client.DefaultHttpClient;

import android.os.Bundle;
import android.os.Environment;
import android.widget.Toast;
import android.app.Activity;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    String url = "http://www.acliberation.comeze.com/upload.php";

    File file = new File(Environment.getExternalStorageDirectory(),
        "kutya.txt"); {

    try {
       HttpClient httpclient = new DefaultHttpClient();

    HttpPost httppost = new HttpPost(url);
       InputStreamEntity reqEntity = new InputStreamEntity(
         new FileInputStream(file), -1);

    reqEntity.setContentType("binary/octet-stream");

    reqEntity.setChunked(true);

    // Send in multiple parts if needed

    httppost.setEntity(reqEntity);

    HttpResponse response = httpclient.execute(httppost);

    Toast.makeText(getApplicationContext(), response.toString(),
         Toast.LENGTH_LONG).show();
       // Do something with response...
      } catch (Exception e) {
          Toast.makeText(getApplicationContext(), e.toString(),
                     Toast.LENGTH_LONG).show();
      }

     }
    }

我的清单是：

  <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.tryyy"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />
    <uses-permission android:name="android.permission.INTERNET" /> 
     <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.tryyy.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

服务器端php是：

<?php
$target_path  = "./";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
 echo "The file ".  basename( $_FILES['uploadedfile']['name']).
 " has been uploaded";
} else{
 echo "There was an error uploading the file, please try again!";
}
?>

我已经下载了针对API 19的SDK的源代码，但问题仍然存在。

提前感谢您的帮助！

稍微修改了你的代码。试试吧

package com.example.tryyy;

import java.io.File;
import java.io.FileInputStream;
import java.net.URI;

import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.InputStreamEntity;
import org.apache.http.impl.client.DefaultHttpClient;

import android.app.Activity;
import android.os.AsyncTask;
import android.os.Bundle;
import android.os.Environment;
import android.widget.Toast;

public class MainActivity extends Activity {

    private String url = "http://www.acliberation.comeze.com/upload.php";
    private String[] params;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        params = new String[2];
        params[0] = Environment.getExternalStorageDirectory() + File.separator + "kutya.txt";
        params[1] = url;
        new HTTPRequest().execute(params);
        setContentView(R.layout.activity_main);
    }

    private class HTTPRequest extends AsyncTask<String, Void, String> {
        protected String doInBackground(String... params) {
            String returnString = null;
            try {
                File file = new File(params[0]);
                URI uri= new URI(params[1]);
                HttpClient httpclient = new DefaultHttpClient();
                HttpPost httppost = new HttpPost(uri);
                InputStreamEntity reqEntity = new InputStreamEntity(new FileInputStream(file), -1);
                reqEntity.setContentType("binary/octet-stream");    
                reqEntity.setChunked(true); 
                // Send in multiple parts if needed
                httppost.setEntity(reqEntity);
                HttpResponse response = httpclient.execute(httppost);
                returnString = response.toString();
                // Do something with response...
            } catch (Exception e) {
                returnString = e.getMessage();
            }
            return returnString;
        }

        protected void onPostExecute(String message) {
            Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();
        }
    }
}
