How to add Apache HTTP API (legacy) as compile-time dependency to build.grade for Android M?

As mentioned here, Android M will not support the Apache HTTP API. The docs state to:

>use the HttpURLConnection class instead.

or >To continue using the Apache HTTP APIs, you must first declare the following compile-time dependency in your build.gradle file: > >android { useLibrary 'org.apache.http.legacy' >}

I have converted much of my project's usage of HttpClient to HttpURLConnection, however, I still need to use the HttpClient in a few areas. Hence, I am trying to declare 'org.apache.http.legacy' as a compile-time dependency but am getting an error in build.gradle:

>Gradle DSL method not found: 'useLibrary()'

My question is: how do I declare 'org.apache.http.legacy' as a compile-time dependency in my project?

Any help is much appreciated. Thanks

For API 23:

Top level build.gradle - /build.gradle

buildscript {
    ...
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.1'
    }
}
...

Module specific build.gradle - /app/build.gradle

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"
    useLibrary 'org.apache.http.legacy'
    ...
}

Official docs (for preview though): http://developer.android.com/about/versions/marshmallow/android-6.0-changes.html#behavior-apache-http-client

Latest android gradle plugin changelog: http://tools.android.com/tech-docs/new-build-system

Another alternative is to just add jbundle dependency. This is more Android Studio friendly as Android Studio doesn't give the message "cannot resolve symbol..."

 dependencies {
    compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
 }

Note for Android 9 (Pie).

Additionally to useLibrary 'org.apache.http.legacy' you have to add in AndroidManifest.xml:

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

Source: https://developer.android.com/about/versions/pie/android-9.0-changes-28

In your build.gradle file add useLibrary 'org.apache.http.legacy' as per Android 6.0 Changes > Apache HTTP Client Removal notes.

android {
    ...
    useLibrary 'org.apache.http.legacy'
    ...
}

To avoid missing link errors add to dependencies

dependencies {
    provided 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
}

using 'provided' the dependency will be not included in the apk

Just copied file: org.apache.http.legacy.jar from Android/Sdk/platforms/android-23/optional folder into project folder app/libs.

Worked like charm for 23.1.1.

I solved this problem like so:

1.) Set classpath in top-level build file as GUG mentioned:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0-beta2'
    }
    allprojects {
        repositories {
           jcenter()
        }
    }
}

2.) In build file of specific module:

android {
   useLibrary 'org.apache.http.legacy'
   compileSdkVersion 'android-MNC'
   buildToolsVersion '23.0.0 rc3'
}

it should help:

android {
    ...
    useLibrary 'org.apache.http.legacy'
    ...
}

To avoid missing link errors add to dependencies

dependencies {
    provided 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
}

or

dependencies {
    compileOnly 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
}

because

Warning: Configuration 'provided' is obsolete and has been replaced with 'compileOnly'.

As the answers are a bit old, I will put my solution (what worked for me), it can be helpful for somebody else... I took my solution from the official documentation of Apache, no work-around.

1/ in gradle:

dependencies {
...
// This is the maintained version from apache.
compile group: 'cz.msebera.android', name: 'httpclient', version: '4.4.1.1'
}

2/ in the rest of the app replace the org.apache.http by cz.msebera.android.httpclient and all your imports (dependencies) will be fixed. you can just do ctrl+shift+R and replace it in the whole project.

FWIW the removal of Apache library was foreshadowed a while ago. Our good friend Jesse Wilson gave us a clue back in 2011: http://android-developers.blogspot.com/2011/09/androids-http-clients.html

Google stopped working on ApacheHTTPClient a while ago, so any library that is still relying upon that should be put onto the list of deprecated libraries unless the maintainers update their code.

<rant> I can't tell you how many technical arguments I've had with people who insisted on sticking with Apache HTTP client. There are some major apps that are going to break because management at my not-to-be-named previous employers didn't listen to their top engineers or knew what they were talking about when they ignored the warning ... but, water under the bridge.

I win.

To resolve the issues make sure you are using build tools version "23.0.0 rc2" with the following tools build gradle dependency:

classpath 'com.android.tools.build:gradle:1.3.0-beta2'

Apache HTTP client deprecated

With Android 6.0, google removed support for the Apache HTTP client. Beginning with Android 9, that library is removed from the bootclasspath and is not available to apps by default.

To continue using the Apache HTTP client, apps that target Android 9 and above can add the following to their

AndroidManifest.xml:

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

Note:

The android:required="false" attribute is required for apps that have a minimum SDK of 23 or lower, because on devices with API levels lower than 24, the org.apache.http.legacy library is not available. (On those devices, the Apache HTTP classes are available on the bootclasspath.)
