Android Post Request Help"},"content":{"rendered":"

Hi guys! Today we are going to code on how to send data from Android to PHP server. This is an example app that can post a file and text data to a web server with PHP file as a receiver. Having the ability to (do HTTP Post Request) post data from android app to remote server is required for most apps. Here are some example use of this functionality:<\/p>\n

1. You want to get statistics on how your app is being used (you have to tell your user and they must agree of course!)
\n2. Your app has an upload file feature.
\n3. A user should register on your database before using more features of your app.<\/p>\n

DOWNLOAD SOURCE CODE<\/p>\n

<\/p>\n

DOWNLOAD HTTPCOMPONENTS LIBRARY<\/h2>\n

In this example, we are using a small library for posting a file, it is called the HttpComponents from the Apache Software Foundation. Please note that you won\u2019t need this library if you\u2019re just posting text data. The download can be found here:\u00a0HttpComponents<\/a><\/p>\n

    \n
  1. As of the moment, I downloaded the binary 4.2.3.zip<\/li>\n
  2. When you extracted the zip file, find the lib folder and copy all the jar files there<\/li>\n
  3. Copy those jar files to your project\u2019s lib folder, here\u2019s how to do that:<\/li>\n
  4. Go to your workspace directory, find your project folder and inside, find the libs folder, put the jar files we extracted earlier<\/li>\n
  5. Go back to eclipse and refresh your project files in the project explorer, now you can see the jar files inside your lib directory. See the screenshot below to visualize the goal of these 5 steps above.<\/li>\n<\/ol>\n
