问题
My app runs normally when ProGuard is disabled.
After ProGuard is enabled, the app is exported into apk and installed into emulator.
Then when I run it in emulator, force close...

proguard-project.txt:
-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
-keep class com.actionbarsherlock.** { *; }
-keep interface com.actionbarsherlock.** { *; }
-keepattributes *Annotation*
-dontwarn org.w3c.dom.bootstrap.**
-dontwarn org.joda.time.**
-dontwarn org.xmlpull.v1.**
How can I fix the error?
Thank you very much!
Updated:
The app can be run in emulator after adding one line to proguard-project.txt:
-keep class * { *; }
Although the app can be run, I think this solution may be not so good...
Any better solution?
Please help.
Thanks a lot.
