推荐答案
文件通过1MB放在资产文件夹不会< STRONG>读从您的应用程序的（它会抛出一个异常）。
Files over 1mb placed in the assets folder won't be readable from your app (It'll throw an exception).
这是因为他们得到 COM pressed 在构建过程中，因此，手机需要大量资源为 uncom preSS 他们当上了手机。
This is because they get compressed during the build process, and thus the phone requires substantial resources to uncompress them when on the handset.
如果在资产是 COM pressed ，该系统具有 uncom preSS 整个事情内存。如果你有一个20MB的资产，这意味着物理内存20MB 是捆绑您的应用程序。
If the asset is compressed, the system has to uncompress the entire thing to memory. If you have a 20MB asset, that means 20MB of physical memory is tied up by your application.
我相信你可以将其放在原始文件夹，他们不会得到 COM pressed
I believe you can place them in the raw folder, where they won't get compressed.
编辑：
