使用 libgdx 和补间引擎的模拟器中的应用程序崩溃

Question

我目前正在做一个项目，到目前为止只完成了启动画面和主屏幕。我想看看它如何在 Android 环境中运行，所以我将它作为 Android 应用程序运行。模拟器启动得很好，但是当它加载应用程序或 "Uploading Project-android.apk to device 'emulator-5554' 正在安装 Project-android.apk...” 它提示它“不幸的是，项目已停止。这里我复制了logcat供参考。

Answer 1

我认为您的具有一些本机功能的 jar 文件版本与没有该方法的 libgdx.so 文件版本不匹配。最好使用 Android NDK 编译 c++ libgdx 库以匹配本机函数。我从你的错误中得到了这个

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

这意味着一些本地方法没有被 JNI 正确绑定

如果您在模拟器中运行，则需要相应的 .so 文件和 libgdx.....so 文件

参考这个Android ndk + libgdx

如果你想要现成的 JAR 文件和 .so 文件在这里下载http://libgdx.badlogicgames.com/nightlies/dist/

您可以看到有 11 个 JAR 文件和文件夹，例如 armeabi/ armeabi-v7a/ x86/

查看 README 文件以了解更多设置需求和编译步骤。

这里也有成功评论Libgdx tween not working on Android

您也可以下载 Demo App https://java-universal-tween-engine.googlecode.com/files/tween-engine-demo-6.3.0.zip 并检查其中的 libs 文件夹是否有 JAR 文件
