如何在 Android M 上使用传统的 Apache HTTP 客户端？

Perfect solution here by running a simple file path check. by running

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


defaultConfig {
applicationId "com.example.user.androidmtest"
minSdkVersion 'MNC'
targetSdkVersion 'MNC'
versionCode 1
versionName "1.0"


}


getBootClasspath().each{File file ->
println file.absolutePath
}
}
}

You will get something like below

/Users/"yourname"/Development/android-sdk-macosx/platforms/android-MNC/android.jar /Users/"yourname"/Development/android-sdk-macosx/platforms/android-MNC/optional/org.apache.http.legacy.jar

So there you go, the jar is there.For some reason it didn't get added to the project. but you can always add it manually I guess.

Android Studio was complaining that org.apache.http classes like

org.apache.http.NameValuePair
org.apache.http.client.utils.URLEncodedUtils

were missing.

So I added org.apache.http.legacy.jar which is in Android/Sdk/platforms/android-23/optional folder to to app/libs

I also added this line to my app.gradle file

compile files('libs/org.apache.http.legacy.jar')

But if you're using more libraries, you can use this way

compile fileTree(dir: 'libs', include: ['*.jar'])

This resolved all my errors that were caused because google removed support of Apache HTTP client.

useLibrary 'org.apache.http.legacy' did not work for me until I upgraded the Gradle tools version in my main build.gradle file of my Android Studio project, as follows:

dependencies {
classpath 'com.android.tools.build:gradle:1.3.0'
}

Legacy Apache library located in

[ANDROID_SDK]\platforms\android-23\optional\org.apache.http.legacy.jar

So you can copy it inside you project libs or just use

compile files("${android.getSdkDirectory().getAbsolutePath()}" + File.separator + "platforms" + File.separator + "android-23" + File.separator + "optional" + File.separator + "org.apache.http.legacy.jar")

in your /app/build.gradle

The answer above just helps the debug builds to run, and release builds that are utilizing gradle.

Insert this inside the application tag on the manifest file, on all project instances that uses the legacy apache classes:

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

This helps for those who are still using Eclipse and ant scripts during compile.

I know this is silly reason but at list try it...

I experienced this problem recently, and it is caused by the path length restriction I think it´s 256 characters maximum.

Relocate your Project and the build will succeed.Hope this work for you.

A simple way to solve this issue is C:\Users\username\AppData\Local\Android\sdk\platforms. Here delete your android-23 and from SDK manager update your API 23 again. It will solve your issue.

First you have to check that in your libs folder

Then add into your gradle file like this


android {
compileSdkVersion 23
buildToolsVersion '23.0.2'


defaultConfig {
applicationId "info.tranetech.laundry"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
android {
useLibrary 'org.apache.http.legacy'
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.0.1
compile 'com.android.support:design:23.0.1
testCompile 'junit:junit:4.12'
compile files('libs/android-async-http-1.4.4.jar')
compile 'com.google.android.gms:play-services:8.4.0'
}

Enable this in sdk/platforms/android-23/optional/optional.json

[
{
"name": "org.apache.http.legacy",
"jar": "org.apache.http.legacy.jar",
"manifest": false
}
]

Remove

useLibrary 'org.apache.http.legacy'

from the build.gradle and I also added this line to my app.gradle file

compile files('libs/org.apache.http.legacy.jar')

But if you're using more libraries, you can use this way

compile fileTree(dir: 'libs', include: ['*.jar'])

How to use the legacy Apache HTTP client on Android Marshmallow?

To continue using Apache HTTP classes for API 23+:

First of all, be sure to add the gradle dependencie into the build.gradle f

buildscript {


dependencies {
classpath 'com.android.tools.build:gradle:2.0.0'
}
}

Then add the reference inside build.gradle of your project:

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

After many frustrating hours, the following worked:

1. Locate the apache jar. It should reside somewhere like:

C:\Users\<yourname>\AppData\Local\Android\sdk\platforms\android-23\optional

2. Copy org.apache.http.legacy.jar to your libs folder.

Either right click on libs -> paste , or use your file explorer to navigate to the libs folder of your project and paste.

If you don't have a libs folder, as I did, make a new project and import all relevant files into their respective places.

3. Click ok see this

4. Most important step: Right click on the apache folder and select Add As Library. see this

Hope this helps someone get on with their life.
