Question

I just started using proguard, and used a file found on this site as my proguard.cfg file:

-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 ; }

-keepclasseswithmembers class * {
public (android.content.Context, android.util.AttributeSet); }

-keepclasseswithmembers class * {
public (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 *; }

when I get to the final step of a signed apk export using eclipse, I get the error:

Proguard returned with error code 1. See console

The console states this:

Judging by the output, I would say that there is supposed to be a proguard.txt file in my apps bin folder, and there isn’t one.

What should this file contain if I make it?

Answer 1

You should update your Android SDK with the interactive android tool and then also update your project with

android update project --path MyProjectDirectory

This should create proguard-project.txt and update project.properties to point to this file.
