android 3.2.2版本官方demo，一混淆就运行闪退

我就把project.properties的这行#proguard.config=proguard-project.txt的#号去掉
官方文档的
-keep class com.hyphenate.** {*;} 
-dontwarn com.hyphenate.**
也没什么用
 
 
下面是官方demo里面的混淆规则。。。。我原封不动，没修改过
# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose
-dontwarn

# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).
-dontoptimize
-dontpreverify
# Note that if you want to enable optimization, you cannot just
# include optimization flags in your own project configuration file;
# instead you will need to point to the
# "proguard-android-optimize.txt" file instead of this one from your
# project.properties file.

-keepattributes *Annotation*
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService

# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native
-keepclasseswithmembernames class * {
    native ;
}

# keep setters in Views so that animations can still work.
# see http://proguard.sourceforge.net/manual/examples.html#beans
-keepclassmembers public class * extends android.view.View {
   void set*(***);
   *** get*();
}

# We want to keep methods in Activity that could be used in the XML attribute onClick
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

-keepclassmembers class **.R$* {
    public static ;
}

-keep class android.support.v4.** {*;}

-keep class org.xmlpull.** {*;}
-keep class com.baidu.** {*;}
-keep public class * extends com.umeng.**
-keep class com.umeng.** { *; }
-keep class com.squareup.picasso.* {*;}

-keep class com.hyphenate.* {*;}
-keep class com.hyphenate.chat.** {*;}
-keep class org.jivesoftware.** {*;}
-keep class org.apache.** {*;}
#另外，demo中发送表情的时候使用到反射，需要keep SmileUtils,注意前面的包名，
#不要SmileUtils复制到自己的项目下keep的时候还是写的demo里的包名
-keep class com.hyphenate.chatuidemo.utils.SmileUtils {*;}

#2.0.9后加入语音通话功能，如需使用此功能的api，加入以下keep
-keep class net.java.sip.** {*;}
-keep class org.webrtc.voiceengine.** {*;}
-keep class org.bitlet.** {*;}
-keep class org.slf4j.** {*;}
-keep class ch.imvs.** {*;}
