NoClassDefFoundError: BouncyCastleProvider

Question

I have an interesting problem on a specific Android version. So I include BouncyCastle dependency in Gradle like this:

compile 'com.madgag.spongycastle:prov:1.51.0.0'

and initialize security provider like this:

import org.spongycastle.jce.provider.BouncyCastleProvider;

...
public void initializeSecurity() {
    Security.addProvider(new BouncyCastleProvider());
}
...

My IDE autocompletes the code related to bouncycastle and on my Nexus 5 everything work just fine. But the problem is that on Samsung GT-I8200N the app crashes with an error:

java.lang.NoClassDefFoundError: org.spongycastle.jce.provider.BouncyCastleProvider

Also I set up the emulator mimicking the Samsung device - API 17 ARM7-a. Same error.

Anybody had a similar problem before?

One more solution you can also [see here](http://stackoverflow.com/questions/10134161/trouble-integrating-bouncycastle-jar) — Najeeb Idrees, Nov 24 '16 at 09:16
No, this does not answer the question why the code works on one Android setup and does not on another. — bvk256, Nov 24 '16 at 09:16
Well, it's the same since the system can't resolve BouncyCastleProvider provider. — bvk256, Nov 24 '16 at 09:29

Sorry, I just messed up my multidex setup. So if anyone will encounter similar problems check if multidex is set up correctly.
