I am trying to use ProGuard with Android. I have found several ProGuard scrips to use, with the following one being an example (I have found several others that are the same or very similar). However, when I try and run ProGuard using this script, I get the error:

"Expecting java type before ';' in line 23 of file ..."

I am completely new to ProGuard. Can someone explain what is going wrong here

Thanks.

  • I'm not the down-voter, but I think the questions like 'where is my bug' is more suited for a forum, because others won't get much out of reading the solution to the bug. If the question is changed slightly to: how to make a proguard config-file that does what i want, it would be a much better question, because the answers would be useful to others.

The problem is here:

native ;

Try changing it to:

native <methods>;

Thanks for the response. I have actually already tried that and it fixes the error on that line, but then I get an error on the 'public (android.content.Context, android.util.AttributeSet);' line. The thing I don't understand is that, based on the posts that I have found, other people have clearly used this script successfully. Were they using an older version of ProGuard or something? Thanks.
Ok, I believe that I have identified the problem. These scripts were posted on some blogs, and it appears that the blogs 'ate' all the elements that were in angle brackets (e.g. the '<methods>' tag). Tracking down those elements and restoring them got it to work. Thanks

As I commented above, it appears that the problem stems from the fact that the blog from which I obtained the scripts seemed to be 'eating' anything with angle brackets. I decided it would be nice to post the corrected code, in case anyone else is looking for it. The corrected code is as follows:

-injars bin(!.svn/**) -outjars obfuscated -libraryjars C:\android-sdk\platforms\android-4\android.jar -optimizationpasses 5 -dontusemixedcaseclassnames -dontskipnonpubliclibraryclasses -dontpreverify -verbose -optimizations !code/simplification/arithmetic,!field/*,!class/merging/* -printmapping proguard.map -keepattributes SourceFile,LineNumberTable -keep public class * extends android.app.Activity -keep public class * extends android.app.Application -keep public class * extends android.app.Service -keep public class * extends android.content.BroadcastReceiver -keep public class * extends android.content.ContentProvider -keep public class com.android.vending.licensing.ILicensingService -keepclasseswithmembernames class * { native <methods>; } -keepclasseswithmembernames class * { public <init>(android.content.Context, android.util.AttributeSet); } -keepclasseswithmembernames class * { public <init>(android.content.Context, android.util.AttributeSet, int); } -keepclassmembers enum * { public static **[] values(); public static ** valueOf(java.lang.String); }

From looking at the error message your compiler gave, it looks like the compiler is practically telling you what the problem is.

"Expecting java type before ';' in line 23 of file ..."

I lost count, but it looks like this line is line 23:

native ;

I don't know about you, but that doesn't look like valid Java at all.

It isn't java, it is a script that is input to ProGuard, which is a java program which takes java code and optimizes, and obfuscates it. I was hoping that someone with experience with ProGuard might know the answer.
