FileNotFoundException Android logcat 错误

2022-01-12 00:00:00 android java libgdx logcat

当我测试桌面版本时，我的游戏运行正常，但是当我启动一个 android 模拟器并尝试在模拟器上运行游戏时，游戏关闭并出现 logcat 错误:

My game runs correctly when I test the desktop version, but when I launch an android emulator and and try to run the game on the emulator the game closes and I get the logcat errors:

我知道错误可能很明显，即找不到文件，但它应该是因为它的位置很好，当我将它作为桌面应用程序运行时，文件很好(我将所有桌面资产复制到android资产，它们完全一样).那么问题可能是什么?

I understand that the error migh be obvious that the file is not found, but it should be as it's location is fine and when i run it as a desktop app the file is fine (I copied all of my desktop assets into the android assets, they there are exactly the same). So what could the problem be?

这是我设置图像的地方:

Here is where i set the image:

Texture playButtonTxture = new Texture(Gdx.files.internal("playButton2.png"));

你应该看看这里并按照以下说明进行操作:https://github.com/libgdx/libgdx/wiki/Manual-project-setup#asset-folder-setup

You should take a look here and follow these instructions : https://github.com/libgdx/libgdx/wiki/Manual-project-setup#asset-folder-setup

Android 项目有一个名为 assets 的子文件夹，它是自动创建的.Android 应用程序可用的文件必须放在此处.这是有问题的，因为这些相同的文件必须对桌面应用程序可用.与其维护所有文件的两个副本，不如将桌面项目配置为在 Android 项目中查找资产 [...]

The Android project has a subfolder named assets, which is created automatically. Files available to the Android application must be placed here. This is problematic, because these same files must be available to the desktop application. Rather than maintain two copies of all the files, the desktop project should be configured to find the assets in the Android project [...]
