splitdexfile导致崩溃：Facebook SDK Parcelable遇到ClassClassNotFoundException，读取Serializable对象

Question

我尝试应用splitdexfile选项将Facebook的sdk拆分为单独的dex文件。

到目前为止我做了什么：

1）我已将以下行添加到我的dexguard-project.txt文件中：

-splitdexfile com.facebook.**

2）在我的project.properties文件的下方：

proguard.config=dexguard-project.txt

3）我已成功导出带有Export Optimized and Obfuscated Application Package... (DexGuard)选项的已签名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.?$?)

我在生成的o.?$?文件中找不到mapping.txt类。

DexGuard版本： 6.1

Facebook SDK版本： 3.22.0

Answer 1

通过在dexguard-project.txt文件中添加以下行来解决此问题：

-keep class * implements java.io.Serializable { *;}
-keepclassmembers class * implements java.io.Serializable { *;}
