LibGDX HelloWorld 项目在 Android 模拟器上运行时崩溃 [英] LibGDX HelloWorld project crashes when run on Android emulator

问题描述

我一直试图让 Hello-World 项目作为学习 LibGDX 的一部分运行.使用夜间构建 (libgdx-nightly-20140322).但是，我变得非常沮丧，因为 hello-world-desktop 项目在作为 Java 应用程序运行时可以运行，而 hello-world-html 项目将作为 Web 应用程序运行.但是 hello-world-android simple 会产生一个描述性不强的错误:

I've been trying to get the Hello-World project to run as part of learning LibGDX. Using the Nightly Build (libgdx-nightly-20140322). However, I have become quite frustrated because the hello-world-desktop project will work when run as a Java Application, the hello-world-html project will Run As a Web Application. But hello-world-android simple produces a not very descriptive error:

我在这里查看过类似的问题，发现 Android Emulator 没有启动 LibGDX 项目?，但给出的解决方案不适用于我所拥有的.还有 libgdx 我的第一个三角形教程不起作用?，它指出我去新教程尝试，但没有用.

I have checked on here looking for similar problems and found Android Emulator does not launch LibGDX project?, but the solution given does not work with what I have. There was also libgdx my first triangle tutorial not working?, which pointed me to new tutorials to try, but no avail.

我第一次尝试遵循 GITHUB，以及第二次从零开始的游戏 LibGDX 教程 1:创建初始项目.我尝试了不同的 API 级别 8、13、16 和19.

The first time I attempted to follow the tutorial on GITHUB, and the second time Games from Scratch's LibGDX Tutorial 1: Creating an initial project. I have tried different API Levels 8, 13, 16, & 19.

推荐答案

正如@Sid 在评论中指出的那样，错误表明 LibGDX 需要 OpenGL ES 2.0 支持.模拟器的软件渲染器不支持 OpenGL ES 2.0.

As @Sid notes in the comments, the error says LibGDX requires OpenGL ES 2.0 support. The emulator's software renderer does not support OpenGL ES 2.0.

您可以通过在模拟器中启用图形加速来让您的模拟器支持.请参阅 http://developer.android.com/tools/devices/emulator.html#accel-graphics 和 Android OpenGL ES 2.0 模拟器

You may be able to get your emulator to support by enabling graphics acceleration in the emulator. See http://developer.android.com/tools/devices/emulator.html#accel-graphics and Android OpenGL ES 2.0 emulator

这是突出显示设置的 Android 虚拟设备管理器对话框.启用此功能绝对可以解决 Macbook Air 以及许多其他计算机上的问题.

Here is the Android Virtual Device Manager dialog with the setting highlighted. Enabling this definitely solves the problem on a Macbook Air, and likely many other computers.
