java.lang.NoClassDefFoundError with AsyncHttpClient - API 19

Question

There is many subject on stack regarding this, but none of them worked :/

I'm running android studio, i added this librarie in gradle, then gradle clean, built project and run app.

            }
        });
    }
}

Some answer were talking about adding manually the jar lib and referencing it in gradle.build, but didn't worked either, on the website of the plugin, the documentation is clear :

https://guides.codepath.com/android/Using-Android-Async-Http-Client

I don't see my mistake here :/

Thanks a lot in advance

EDIT: importing the jar file into the libs folder then, add to library, and importing the libs for the header manually in gradle:

compile 'cz.msebera.android:httpclient:4.3.+'

give different error:

java.lang.NoClassDefFoundError: com.loopj.android.http.LogHandler

There must a bug :( i don't see any other options

EDIT 2: Works fine on API 21..., is this library incompatible with API 19 ??

I know that you are importing this class with import com.loopj.android.http.*; but I had some issues importing in this way try import com.loopj.android.http.AsyncHttpClient. Hope It helps you. — Miguel Benitez, Apr 11 '16 at 15:50
@MiguelBenitez: Thanks for your suggestion, unfortunately it didn't made the trick :( — RaccoonDeveloper, Apr 11 '16 at 15:57
Did you used "Invalidates Cache and restart" from Android Studio main menu? — Víctor Martín, Apr 11 '16 at 15:58
@MAOL: Thanks, Just tried, didn't worked either :/ the worst is that when i right click, go to declaration, it goes to it :@ — RaccoonDeveloper, Apr 11 '16 at 16:04

Enable multidex

defaultConfig {
...
 // Enabling multidex support.
multiDexEnabled true
}

Add dependency

dependencies {
    compile 'com.android.support:multidex:1.0.1'
}

Add codes in your application

@Override
protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
}

That worked for me, i hope it is helpful for you.

It may be related to multiDex feature.

You can disable it by removing "multiDexEnabled true" line in your gradle file.

Or follow the multidex guide:

Set multiDexEnabled true
Add dependency 'com.android.support:multidex:1.0.0'
Replace Application to MultiDexApplication

A missing dependency has nothing to do with Multidex – OneCricketeer Apr 11 '16 at 18:00
I would like to mention that after multiple attempts, i just noticed that its not throwing any exception on API 21 ... Is this library incompatible with API 19 ?? – RaccoonDeveloper Apr 11 '16 at 18:10
Did you setup multidex as I said? ART (Android 5.0) default supports multidex but Android 4.4 doesn't. – Richard Chang Apr 11 '16 at 18:20
Hi Richard, thanks for your answer but actually it was needed this param otherwise it wouldn't even build the project, anyway now that i know the answer about what was the problem, i can give up properly on ever using this library – RaccoonDeveloper Apr 11 '16 at 18:32
Hi @RaccoonDeveloper, I think you misunderstood the description. They said "Compatible with Android API 23 and higher" is because Google removed some apache http apis which loopj used before 1.4.8. So 1.4.9 is a whole new package which built in the apache http apis. Btw, you said API21 is fine, right? – Richard Chang Apr 11 '16 at 18:47
@RichardChang: Yes its fine on API 21, but my app needs to target much wider than api 21, the bare minimum would have been 17 or 19, not 21 :/ – RaccoonDeveloper Apr 11 '16 at 18:49
Please see my answer again, you need to follow this to setup your multidex (for api 19 or lower): https://developer.android.com/intl/zh-tw/tools/building/multidex.html – Richard Chang Apr 11 '16 at 18:53
@RichardChang: Ok, will check that tomorrow first hour, its already quite late in france ;) thx for ur suggestion, i let you know asap tomorrow morning – RaccoonDeveloper Apr 11 '16 at 19:04
