HTTPPoster

A little library to easily HTTP POST variables & files in Android.

This code is an merge of this Stack Overflow post and this solution put in a nice AsyncTask, with configuration and a listener for all events.

It is also updated to the newest Android API, as HttpPost and HttpClient classes are deprecated in favor of HttpURLConnection.

This tiny library is composed of 3 classes:

• HttpListener - An interface you need to implement to listen for callbacks.
• HttpConfiguration - A helper class holding the configuration & content of the HTTP POST Request to execute.
• HttpPoster - The main class - the ASyncTask that will execute the POST requets based on the given HttpConfiguration, sending back signals through the HttpListener.

How to use?

Android Studio Setup

In your Android Studio project, create a folder called libs, for example: ./AndroidStudioProject/MyProject/libs

Download the repository files and unpack either:

• At the root of ./AndroidStudioProjects/ then create a symbolic link from ./AndroidStudioProject/MyProject/libs/HTTPPoster to ./AndroidStudioProject/HTTPPoster/library
• The directory "library" into the ./AndroidStudioProject/MyProject/libs/ directory and rename the "library" folder to "HTTPPoster"

In your settings.gradle Project file, add the following:

include ':libs:HTTPPoster'

In your build.gradle Module file (usually "app"), add the dependency:

dependencies {
    ...
    implementation project(':libs:HTTPPoster')
}

Quick usage

import java.io.File;
import java.net.URL;
import java.util.ArrayList;
import java.util.HashMap;

import com.licryle.httpposter.HttpConfiguration;
import com.licryle.httpposter.HttpPoster;
...
HashMap<String, String> mArgs = new HashMap<>();
mArgs.put("lat", "40.712784");
mArgs.put("lon", "-74.005941");

ArrayList<File> aFileList = getMyImageFiles();

URL mEndPoint = new URL("http://www.mysite.com/HttpPostEndPoint");

HttpConfiguration mConf = new HttpConfiguration(
        mEndPoint,
        mArgs,
        aFileList,
        this,  // If this class implements HttpListener
        null,   // Boundary for Entities - Optional
        15000,  // Timeout in ms for the connection operation
        10000   // Timeout in ms for the reading operation
);

new HttpPoster().execute(mConf);
