java.lang.NoClassDefFoundError

[imdutch21]

I seem to be having a problem with using the api. I've made a little program for testing the capabilities of the api, but after trying to build a new instance of the api
Api api = Api.builder().accessToken(oauthToken).clientId(CLIENT_ID).redirectURI(UIR).build();
the following error is given:
java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/impl/conn/PoolingHttpClientConnectionManager;

Full error log: https://pastebin.com/N9ihEaJt

I've looked online for solutions, but I can't seem to find any fixes that work. Has anyone got any clue for how to fix this?

Dependencies:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    compile 'com.spotify.sdk:spotify-player-24-noconnect-2.20b@aar'
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.spotify.android:auth:1.0.0-alpha'
    testCompile 'junit:junit:4.12'

    compile('se.michaelthelin.spotify:spotify-web-api-java:1.7.3') {
        exclude group: "commons-beanutils", module: "commons-beanutils"

    }
    compile 'commons-beanutils:commons-beanutils:20030211.134440'
}

I'll look into this. Are you using Android? You may use kaaes/spotify-web-api-android instead.

[imdutch21]

Oh yes I am. I've tried that api as well, but I was having a different issue with that one. I actually thought this one was for android as well. If the issue has no easy fix, I'll look into kaaes' wrapper again

[dargmuesli]

Could you please give me an exact explanation on how you've set up your project? Tools, files, ...
I haven't used Gradle myself yet and did never develop for Android, so examining this would take long without this information.

[imdutch21]

Sure
I'm using android studio 2.3, but I think that shouldn't matter

For the virtual device I use the Pixel XL with api 24
If you need anything else, I'm happy to help

[imdutch21]

Actually I forgot to mention I'm also using Spotify's android sdk for authentication

[dargmuesli]

Have you tried using the new version 2.0.0-RC1 of this project? Does the same problem still occur?

[dargmuesli]

Ok, I've narrowed down the issue. Sadly, this cannot be fixed. Other people call this issue

a colossal cock-up

on which I must fully agree.

It boils down to Android's included, but very very outdated and thus incompatible version of the httpclient dependency this project relies on too (even v2). There are efforts making usage of the current dependency versions possible, but this would mean that we'd need to include a different package and not the original. As far as I can see this would make no sense for this project as there are others (like kaaes') that are specifically made for Android.

Further explanation: HttpClient for Android

Sorry for the inconvenience, I'll change the README accordingly. Good luck with your project!

[imdutch21]

Okay I understand! Thank you for all your effort and I will try to make the best out of my project!
