Client端

1. 先在Manifest.xml加上

1

2

<uses-permission android:name="android.permission.INTERNET"/>

2. 創建一個Activity：UploadFile.java

package com.example.photothrow1;

import java.io.File;
import java.io.FileInputStream;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;

3. layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
 
    <ImageView
        android:id="@+id/imageView_pic"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_gravity="center"
        android:src="@drawable/ic_launcher" />
 
    <Button
        android:id="@+id/button_selectpic"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Select Picture" />
 
    <Button
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Click To Upload File"
        android:id="@+id/uploadButton"
    />
       
    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text=""
        android:id="@+id/messageText"
        android:textColor="#000000"
        android:textStyle="bold"
    />
 
 </LinearLayout>

Server端：

1. 新增一個PHP檔到你的Server：UploadToServer.php

<?php
  
   $file_path = "uploads/";
     
   $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
   if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
       echo "success";
   } else{
       echo "fail";
   }
?>

2. 新增一個uploads資料夾在相同目錄下
