我正在尝试从已安装的obb扩展文件加载纹理,但是AndEngine无法打开该文件。那是我的代码:
BuildableBitmapTextureAtlas atlas = new BuildableBitmapTextureAtlas(textureManager, 2048, 2048, TextureOptions.BILINEAR_PREMULTIPLYALPHA);
BitmapTextureAtlasTextureRegionFactory.setAssetBasePath(obbManager.getMainRoot() + "/");
File file = new File(obbManager.getMainRoot() + "/background.png");
if (file.exists()) {
System.out.println("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
}
background = BitmapTextureAtlasTextureRegionFactory.createFromAsset(atlas, this, "background.png");
这就是我在Logcat中看到的:
02-10 22:40:09.170: INFO/System.out(20962): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
02-10 22:40:09.180: ERROR/AndEngine(20962): Failed loading Bitmap in AssetBitmapTextureAtlasSource. AssetPath: /mnt/obb/8d6d9efb8ab5fbfaa452d7ff7e8047c5/background.png

因此,该文件存在,但我仍在获取FileNotFoundException。
最佳答案
我知道了:createFromAsset
试图不在我的文件中找到我的文件,而是在apk的/mnt/.../background.png
中找到我的文件。所以我应该使用AndEngine的FileBitmapTextureAtlasSource:
BitmapTextureAtlasTextureRegionFactory.createFromSource(atlas, FileBitmapTextureAtlasSource.create(file))
