Android Gradle Build Error

Question

I am adding dependencies in build.gradle file.

My code is :

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.google.android.gms:play-services:6.1.11'
compile 'org.apache.httpcomponents:httpmime:4.4.1'
compile 'org.apache.httpcomponents:httpcore:4.4.1'
compile 'org.apache.httpcomponents:httpclient:4.4.1'

}

I got error :

Warning:Dependency org.apache.httpcomponents:httpclient:4.4.1 is ignored for debug as it may be conflicting with the internal version provided by Android.
     In case of problem, please repackage it with jarjar to change the class packages

How to solve this problem. Please help me ?

Answer 1

You can try by adding this in your build.gradle (Module: app). It solved my issue:

packagingOptions{
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
}

My final build gradle looks like:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "info.androidhive.camerafileupload"
        minSdkVersion 19
        targetSdkVersion 21
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
    packagingOptions{
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:21.0.3'
    compile files('libs/httpclient-4.3.6.jar')
    compile files('libs/httpcore-4.3.3.jar')
    compile files('libs/httpmime-4.3.6.jar')
}

NB: In my case I have pasted this 3 jars in my libs folder. You can download and do so.

I solved this issue by replacing following line

compile "org.apache.httpcomponents:httpclient:4.4.1"

with this

compile "org.apache.httpcomponents:httpclient-android:4.3.5.1"
