App crashes in emulator using libgdx and tween engine

Question

I'm currently working on a project and so far only have the splash and main screen done. I wanted to see how it would run in an Android environment so I ran it as an Android Application. The emulator booted up just fine but when it load the app or "Uploading Project-android.apk onto device 'emulator-5554' Installing Project-android.apk..." it prompts up that it "Unfortunately, Project has stopped. Here I copied the logcat for reference.

Answer 1

I think your jar file version which has some native functions does not matches the libgdx.so file version which does not have that method. Better you compile the c++ libgdx library using Android NDK to match the native functions. I got this from your error

No JNI_OnLoad found in /data/app-    lib/com.levellabs.project.android-2/libgdx.so 0xb1fbed48, skipping init
......
......
Could not find method     aurelienribon.tweenengine.TweenManager.update, referenced from method     com.levellabs.project.GameScreen.render

This means some of the native methods are not properly binded by the JNI

If you are running inside an emulator, you need corresponding .so files live libgdx.....so files

Refer this Android ndk + libgdx

If you want the ready made JAR files and .so files download here http://libgdx.badlogicgames.com/nightlies/dist/

You can see there are 11 JAR files and folders like armeabi/ armeabi-v7a/ x86/

Go through the README files for further setup needs and compilations steps.

There is also a success comment here Libgdx tween not working on Android

You can also download the Demo App https://java-universal-tween-engine.googlecode.com/files/tween-engine-demo-6.3.0.zip and check the libs folder inside it for the JAR files
