android - Proguard JavascriptInterface <print> -

i have problems proguard export apk. proguard says: proguard.parseexception: expecting class member name before ';' line : print;

i need this in class:

public class jiface {     @javascriptinterface     public void print(string data) { 

when removed progurad interface dont call.

progurad:

-keepclassmembers class * {     @android.webkit.javascriptinterface <methods>; }  -keepattributes javascriptinterface  -keepattributes *annotation*  -keepattributes javascriptinterface -keep public class com.imh.sos.webcpu_mail$jiface -keep public class * implements com.imh.sos.webcpu_mail$jiface -keepclassmembers class com.imh.sos.webcpu_mail$jiface {      <methods>;  }   -keepattributes javascriptinterface -keep public class com.imh.sos.webcpu_mail$print -keep public class * implements com.imh.sos.webcpu_mail$print -keepclassmembers class  com.imh.sos.webcpu_mail$print {      <methods>;  }     -keepattributes javascriptinterface -keep public class com.imh.sos.webcpu_mail$jiface -keep public class * implements com.imh.sos.webcpu_mail$jiface -keepclassmembers class com.imh.sos.webcpu_mail$jiface {      <print>;  }  -keepattributes javascriptinterface -keep public class com.imh.sos.webcpu_mail$print -keep public class * implements com.imh.sos.webcpu_mail$print -keepclassmembers class com.imh.sos.webcpu_mail$print {      <print>;  } 

sdk 19.

thank you

this works me:

-keep public class package_name.activity_name$myjavascriptinterface  -keep public class * implements package_name.activity_name$myjavascriptinterface -keepclassmembers class package_name.activity_name$myjavascriptinterface { <methods>;}  -keepattributes javascriptinterface
