這是一個適合您的好東西。Libgdx：打開外部文件時找不到文件錯誤'Internal'
我想用外部打開文件。
FileHandle dirHandel = Gdx.files.external("MyApps/skanectModel.g3db");
boolean isDir = Gdx.files.external("MyApps/skanectModel.g3db").exists();
我知道文件在那裏，布爾告訴我，實際上它在那裏。
主要問題是我得到這個錯誤。
Caused by: com.badlogic.gdx.utils.GdxRuntimeException: Error reading file: MyApps/skanectModel.png (Internal)
我不知道爲什麼要這麼做，我沒有在尋找一個內部文件。
出於好奇，我創建了我的資產文件夾中的文件就這樣assets/MyApps/skanectModel.png和代碼運行完美，也應用程序可以在我的Android播放。
但是...我需要能夠只讀取外部。我正在爲一些朋友構建一個簡單的3D查看器，我會不時地發送給他們3D模型。
這裏是代碼的副本：

******編輯***** 從MadEqua迅速提醒後，這是我如何實現修復。
FileHandle dirHandel = Gdx.files.external("MyApps/skanectModel.g3db");
myT = new TextureProvider() {
@Override
public Texture load(String fileName) {
Texture result = new Texture(Gdx.files.external(fileName));
result.setFilter(Texture.TextureFilter.Linear, Texture.TextureFilter.Linear);
result.setWrap(Texture.TextureWrap.Repeat, Texture.TextureWrap.Repeat);
return result;
}
};
myT.load("Myapps/skanectModel.png");
model = modelLoader.loadModel(dirHandel,myT);
我會吻你，如果我可以.... !!!奇蹟般有效。這個是我做過的： FileHandle dirHandel =紋理結果=新紋理（Gdx.files.external（fileName））;紋理結果=新紋理（Gdx.files.external（fileName））;紋理結果=新紋理（Gdx.files.external（fileName））; result.setFilter（Texture.TextureFilter.Linear，Texture.TextureFilter.Linear）; result.setWrap（Texture.TextureWrap.Repeat， Texture.TextureWrap.Repeat）; \t \t \t \t返回結果; \t \t \t} \t \t}; myT.load（「Myapps/skanectModel.png」）; model = modelLoader.loadModel（dirHandel，myT）; –
是的，它也花了我一段時間才明白這是一個紋理問題。順便說一下，這條線什麼都不做，可以刪除：'myT.load（「Myapps/skanectModel.png」）;'。負載在ModelLoader內部調用。不過，沒有吻。 ;-) – MadEqua
