Using Proguard with Android without obfuscation

Question

I am getting an error "Conversion to Dalvik format failed with error 1" when using the -dontobfuscate flag. Otherwise my app exports fine. I don't want to obfuscate because I am using BugSense for error tracking and they charge $99 a month if you need to de-obfuscate your stack traces. I still want to get the file size and optimization benefits of proguard.

If I comment out -dontobfuscate every thing works great. Except for the unreadable stack traces.

my progaurd.cfg file:

-dontobfuscate -optimizationpasses 5 -dontusemixedcaseclassnames -dontskipnonpubliclibraryclasses -dontpreverify -verbose -optimizations !code/simplification/arithmetic,!field/*,!class/merging/*  -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 * extends android.app.backup.BackupAgentHelper -keep public class * extends android.preference.Preference -keep public class com.android.vending.licensing.ILicensingService  -keepclasseswithmembernames class * {     native <methods>; }  -keepclasseswithmembers class * {     public <init>(android.content.Context, android.util.AttributeSet); }  -keepclasseswithmembers class * {     public <init>(android.content.Context, android.util.AttributeSet, int); }  -keepclassmembers class * extends android.app.Activity {    public void *(android.view.View); }  -keepclassmembers enum * {     public static **[] values();     public static ** valueOf(java.lang.String); }  -keep class * implements android.os.Parcelable {   public static final android.os.Parcelable$Creator *; } 

I will also accept an answer that points me in the right direction. Is there a log file I should be looking at?

Answer 1

Add !code/allocation/variable is workaround for ProGuard bug when -dontobfuscate is set to your -optimizations

For example

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*,!code/allocation/variable
