[SOLVED] java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader couldn't find "libdecodejme.so"

Pavl_G · March 31, 2021, 9:59pm

I know that android audio was fixed beginning from v3.4.0-alpha4
So, when trying it , i get this exception :

…Notice : this exception isn’t related by any means to the audio , it means that the android native object file that wraps the native module package isn’t found …it’s the same as :

2)AndroidNativeImageLoader failing to load · Issue #1294 · jMonkeyEngine/jmonkeyengine · GitHub

Pavl_G · March 31, 2021, 10:05pm

I suggest to merge both the native & the java module , but we will need to test this before doing the merge.

EDIT :

This happens when i add android-native3.4.0-alpha4 in gradle :

    implementation "org.jmonkeyengine:jme3-android-native:3.4.0-alpha4"

sgold · April 1, 2021, 12:10am

how about

runtimeOnly 'org.jmonkeyengine:jme3-android-native:3.4.0-alpha4'

?

Ali_RS · April 1, 2021, 7:39am

I can reproduce this as well with 3.4.0-alpha4.

It works fine on 3.4.0-alpha3.

These are the changes from alpha3 to alpha4:

Ali_RS · April 1, 2021, 7:41am

No difference.

Ali_RS · April 1, 2021, 8:36am

Hmm, the jme3-android-native.jar that is uploaded to the Maven central repo is empty and does not contain the lib directory. That’s why it can not find the natives.

Seems something is broken while migrating from Bintray to Maven central.

Edit:

Filled an issue on GitHub page

Pavl_G · April 1, 2021, 10:49am

That’s true though , it doesn’t include the native module ‘decodejme’ , it just has only a META-INF folder , but the jar file isn’t actually corrupted.

Ali_RS · April 1, 2021, 10:52am

For now, you can use the jme3-android-native:3.4.0-alpha3 from Bintray. Audio should work fine in that release.

Pavl_G · April 1, 2021, 11:58am

i get this

com.jme3.asset.AssetLoadException: An exception has occurred while loading asset: AssetsForRenderer/Audio/shocks.ogg (Stream/Cache)

EDIT :

Okay , it has worked with .wav files but this is a converted ogg from wav , it cannot be loaded , although the ogg file runs well with VLC

Ali_RS · April 1, 2021, 12:03pm

Did you add jme3-jogg in your build.gradle dependencies?

Ali_RS · April 1, 2021, 12:23pm

Hmm, never mind, I guess jme3-jogg is only for desktop and not needed in android.

Can you try with ogg files in jme-testdata?

Pavl_G · April 1, 2021, 12:25pm

i have tried this now , it didn’t work.

Ali_RS · April 1, 2021, 12:31pm

Just tried with jmonkeyengine/Ocean Waves.ogg at master · jMonkeyEngine/jmonkeyengine · GitHub and it works fine for me.

Note I tried with JME 3.4.0-alpha3.

Pavl_G · April 1, 2021, 12:32pm

Okay , thanks , i will try this.

sgold · April 1, 2021, 9:34pm

Please re-test using v3.4.0-alpha6

Ali_RS · April 2, 2021, 5:25am

It works fine for me. Thanks

~~By the way, I do not see v3.4.0-alpha6 in https://mvnrepository.com/artifact/org.jmonkeyengine/jme3-android-native, is that intentional or will it take some time to get listed?~~ (Never mind, they have appeared now)

Also, I notice the jar size has increased from 1.1MB in alpha1 to 3.6MB in alpha6. Can be because of turning off the optimization flag on native code?

Pavl_G · April 2, 2021, 3:31pm

Yep it works fine , thanks @sgold .

Pavl_G · April 2, 2021, 3:33pm

So what about this issue , now , seems the same but it’s since 2020 !

sgold · April 2, 2021, 4:28pm

That seems entirely possible.

So what about this issue , now , seems the same but it’s since 2020 !

Multiple issues can have the same symptoms but different root causes. What’s the root cause of issue 1294?

Pavl_G · April 2, 2021, 4:31pm

Idk , you should probably ask @Darkchaos to how to reproduce it , so we could have probably a good idea of its root cause , but i think this problem (module not found) wouldn’t have too much causes , it may be a network cause (like : libraries get corrupted while fetching from the central repo).
