Question

android-android怎么实现只混淆自己的代码，而不混淆第3方jar.201

Answer 1

　　为了解决第三方包不被混淆，第三方包在混淆后，运行的时候会挂掉。我的错误是java.lang.ExceptionInInitializerError

[java] E/AndroidRuntime( 9608):
java.lang.ExceptionInInitializerError
E/AndroidRuntime( 9608): at
a.a.b.f.<init>(Unknown Source)
E/AndroidRuntime( 9608): at
a.a.b.e.<init>(Unknown Source)
E/AndroidRuntime( 9608): at
a.a.c.dg.b(Unknown Source)
E/AndroidRuntime( 9608): at
a.a.c.dg.a(Unknown Source)
E/AndroidRuntime( 9608): at
a.a.c.b.a(Unknown Source)
E/AndroidRuntime( 9608): at
a.a.c.ad.a(Unknown Source)

　　………………………………………………………………………………中间部分省略
　　最终我通过 加LOG的调试方法定位到是由于第三方jar包被混淆后的原因导致的。

　　解决方法：
　　在proguard-android.txt文件最后加入了-keep class org.jsoup.**这样一句代码，就是保持这个类不被混淆

　　附上proguard-android.txt源文件
