正如我所说 here ，如果数据被压缩，您的问题可能来自数据的大小:

Hi guys, If I remember well, I had the same kind of issue when loading stuff from the asset folder but with a database. It seems that the stuff in your asset folder can have 2 stats : compressed or not. If it is compressed, then you are allowed 1 Mo of memory to uncompress it, otherwise you will get this kind of exception. There are several bug reports about that because the documentation is not clear. So if you still want to to use your format, you have to either use an uncompressed version, or give an extension like .mp3 or .png to your file. I know it's a bit crazy but I load a database with a .mp3 extension and it works perfectly fine. This other solution is to package your application with a special option to tell it not to compress certain extension. But then you need to build your app manually and add "zip -0" option. The advantage of an uncompressed assest is that the phase of zip-align before publication of an application will align the data correctly so that when loaded in memory it can be directly mapped.

So, solutions :

• change the extension of the file to .mp3 or .png and see if it works
• build your app manually and use the zip-0 option
