我尝试应用splitdexfile选项将 Facebook 的 sdk 拆分为单独的 dex 文件。
到目前为止我所做的：
1）我在我的dexguard-project.txt文件中添加了以下行：
-splitdexfile com.facebook.**
2）在我的project.properties文件下面一行：
proguard.config=dexguard-project.txt
3)我已经成功导出了一个带有Export Optimized and Obfuscated Application Package... (DexGuard)选项的签名 apk。
4）我检查并确认apk被拆分为2个dex文件：
然后我将apk安装到设备上，并尝试了facebook connect并得到了；
java.lang.RuntimeException: Parcelable encounteredClassNotFoundException reading a Serializable object (name = o.?$?)
o.?$?我在生成的mapping.txt文件中找不到类。
DexGuard 版本： 6.1
Facebook SDK 版本： 3.22.0
