的ExceptionInInitializerError物理世界 [英] ExceptionInInitializerError Physics World

问题描述

我搜索在一些论坛，这似乎是一个常见的​​问题。但我不能找到一个解决方案。如此看来STANGE，出现这种情况我没有做任何疯狂。

  @覆盖
保护场景onCreateScene（）{
    场景S =新场景（）;
    PhysicsWorld mWorld =新PhysicsWorld（新Vector2（0，SensorManager.GRAVITY_EARTH），TRUE）;
    s.registerUpdateHandler（mWorld）;
    最终的Sprite eliSprite =新的Sprite（400，240，james_walking [3]，getVertexBufferObjectManager（））;
    eliSprite.setScale（0.5F）;
    s.attachChild（eliSprite）;
    s.setTouchAreaBindingOnActionDownEnabled（真正的）;
    返回S;
}
 

我没有多说，因为我不知道很多关于Andengine这样一个傻瓜的解释将是preciated。    将你所说的话后，错误熄灭，但是PhysicsWorld仍然不起作用。在logcat的说

解决方案

大概是本地库（.so从lib目录文件）从你的APK失踪。检查项目设置/生成配置。

如果您使用的是Android的工作室，你必须修改andEngine和andEnginePhysicsBox2DExtension的sourceSet在build.gradle。

您必须在项目中有那么文件的文件夹，你需要从那里包括本地库。

检查我的答案在这里：没有延续 jniLibs在摇篮

根据您的意见更新：

这添加到andEngine，andEnginePhysicsBox2d和你的游戏build.gradle：

  sourceSets {
    主要 {
        jni.srcDirs = []
        jniLibs.srcDir'库'
    }
}
 

另外补充这对defaultConfig部分中，andEngine：

  NDK {
   MODULENAMEandEngine
}
 

和andEnginePhysicsBox2d：

  NDK {
    MODULENAMEandEnginePhysicsBox2dExtension
}
 

I searched in a number of forums and it seems to be a common question. However i couldnt find a solution. I didnt do anything crazy so it seems stange that this happens.

@Override
protected Scene onCreateScene() {
    Scene s = new Scene();
    PhysicsWorld mWorld=new PhysicsWorld(new Vector2(0, SensorManager.GRAVITY_EARTH),true);
    s.registerUpdateHandler(mWorld);
    final Sprite eliSprite = new Sprite(400, 240, james_walking[3], getVertexBufferObjectManager());
    eliSprite.setScale(0.5f);
    s.attachChild(eliSprite);
    s.setTouchAreaBindingOnActionDownEnabled(true);
    return s;
}

I dont have much more to say because i dont know much about Andengine so a dummies explanation would be apreciated. After adding what you said the error goes out, however the PhysicsWorld still doesnt work. THe logcat says

02-27 17:07:51.153    2590-2639/com.company.m.appname D/dalvikvm﹕ No JNI_OnLoad found in /data/data/com.company.m.appname/lib/libandenginephysicsbox2dextension.so 0x41cdce70, skipping init

解决方案

Probably native libraries (.so files from lib dir) is missing from your APK. Check your project settings / build configuration.

If you're using android studio, you have to modify the sourceSet of andEngine and andEnginePhysicsBox2DExtension in build.gradle.

You have a folder in that projects where there are so files, you need to include the native libraries from there.

Check my answer here: jniLibs are not extended in gradle

Update based on your comments:

Add this to andEngine, andEnginePhysicsBox2d and your game build.gradle:

sourceSets {
    main {
        jni.srcDirs = []
        jniLibs.srcDir 'libs'
    }
}

Also add this to the defaultConfig section, for andEngine:

ndk {
   moduleName "andEngine"
}

and for andEnginePhysicsBox2d:

ndk {
    moduleName "andEnginePhysicsBox2dExtension"
}
