NoClassDefFoundError Crash

[GBenoitG]

Hi,

I found your project after some research on the mesh network and it looks cool, so I wanted to test it, but I have a crash when launching my app.

java.lang.NoClassDefFoundError: com.ubudu.mesh.obfuscated.d at com.ubudu.mesh.UbuduMeshSDK.getMeshManager(SourceFile:45) at com.test.rdudubutest.MainActivity.onCreate(MainActivity.kt:18) at android.app.Activity.performCreate(Activity.java:5451) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1093) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2358) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2452) at android.app.ActivityThread.access$900(ActivityThread.java:172) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1302) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:136) at android.app.ActivityThread.main(ActivityThread.java:5586) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:515) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1268) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1084) at dalvik.system.NativeStart.main(Native Method)

I just implemented the lib via the file '.jar' and instantiated UbuduMeshManager due to UbuduMeshSDK.getInstance().getMeshManager(this)

I googled this error NoClassDefFoundError but no solutions founded

Hello, I will check this asap and get back to you with fixed release jar. In the meantime I think if you try using gradle dependency in Android Studio then it will work without problems. W dniu pt., 14.04.2017 o 17:34 MrLeblond <notifications@github.com> napisał(a):

Hello @MGasztold

Thank you for your consideration.
I also tryed to using gradle dependency like is mentionned in Readme.md :

compile('com.ubudu.indoorlocation:ubudu-mesh-sdk:1.1.8@aar') {
	transitive = true 
}

But it doesn't works, the project doesn't want to sync, so I checked your SampleApp Project, and found a new dependency :

repositories {
    maven { url 'http://5.135.82.92:8081/nexus/content/groups/public/' }
}
compile('com.ubudu.mesh:ubudu-mesh-sdk:1.1.8@aar')  {
        transitive = true
}

And works !! But why I need to do this like this, that's a good question.

Best regards :)
