Answer 1

I know this is an old thread but it make be worth mentioning that these jars are now included in the eclipse Android ADT bundle (for MAC anyway, I have not checked for Windows). You do need to check the version is the one you want, but if it is you are good to go.

This means you can add them to your project without having to download them separately first - just follow these steps:

First right click your project and select properties as shown below:

Then select Java Build Path from the pop up window:

and now select the 'Libraries' tab:

and click on 'Add external JARS' and navigate to your ADT bundle/sdk/tools/lib/httpclient (httpmime etc), and then just click open:

You also need to import the Jar file itself into your project. I found the best way to do this was to simply copy the JAR files into the 'libs' folder in your project - i.e. CTRL C and CTRL V, or normal drag and drop file copy. To be safe I would refresh (right click project and select refresh - see menu in first picture above) and then clean your project.

Note if you do the Build Path part above correctly but forget to add the JAR files themselves into your 'libs' folder, you will get an error like: 'Caused by: java.lang.NoClassDefFoundError: org.apache.http.entity.mime.content.FileBody'.

To resolve this just copy the jar files into the 'libs' folder in your project.

You should now be good to go!

Answer 2

try to download it from HttpClient Downloads

Answer 3

Download the jars from the apache commons site and add them to project and path.

[Edit] now in Apache HttpComponents http://hc.apache.org/downloads.cgi

Answer 4

download the jar from here : http://commons.apache.org/

install it in your project like this:

Right click on your project and go to properties. On the left tab go to "java build path". And in that on right go to libraries. Click on add external jars and give the path of the jar and your library is added.

Answer 5

If you are using android studio add the following import to your code:

import org.apache.http.entity.mime.content.FileBody;

The IDE will give you an error under "mime" and ask you if you would like to install the dependancy. So if you say yes it will search for it online and then you can download it to app/build/libs directory. FileBody will then be recognized after this process is complete.

Answer 6

Add these two dependency

compile "org.apache.httpcomponents:httpcore:4.2.4"
compile "org.apache.httpcomponents:httpmime:4.3"

It will work.
