推荐答案
您不能做到这一点。当你编译Java源文件时，它首先被编译成一个.class文件是Java字节code。在这以后，类文件然后重新编译成.dex文件，该文件是在Dalvik字节code其中Dalvik虚拟机可以运行。这.dex文件是那么COM pressed成.apk文件是包含所有应用程序的数据归档。你可以阅读更多关于它这里 。
You can not do this. When you compile a java source file it is first complied into a .class file which is Java byte code. After that the class files are then compiled again into a .dex file which is the Dalvik byte code which the Dalvik virtual machine can run. This .dex file is then compressed into an .apk file which is the archive which contain all your application's data. You can read more about it here.
