proguard

I am trying to process with Proguard a MS Windows desktop application (Java 6 SE using the SWT lib provided by Eclipse). And I get the following critical error: Unexpected error while performing partial evaluation: Class = [org/eclipse/swt/widgets/DateTime] Method = [<init>(Lorg/eclipse/swt/widgets/Composite;I)V] Exception = [java.lang.IllegalArgumentException] (Can't find common super class of [java/lang/StringBuffer] and [org/eclipse/swt/internal/win32/TCHAR]) Error: Can't find common super class of [java/lang/StringBuffer] and [org/eclipse/swt/internal/win32/TCHAR] -------------------------

From what I've seen and read, if someone really wants to reverse-engineer your software or decompile it, ProGuard is not going to stop them. But is it at least a modest deterrent? I'm not sure if it's worth the hassle of translating my stack traces later on. I would recommend ProGuard. Even without obfuscation (which can significantly shorten the names used in the constant pool) it can remove "dead code" (unused methods) of used libraries, etc. (It can also be used to conveniently merge everything together). It takes a little bit of fiddling to "get correct", esp. if there is dynamically

I currently use a combination of LVL and Proguard as a first line of defence against piracy. However, what about the resource strings? For example, if there is a resource string like "License check failed" then doesn't the pirate simply need to trace that resource id back to where it was used in the code? In fact, this is also true if the string is something generic like "Please contact dev". What is the best approach? If you define a resource string, you will probably define or use it in: the string resource file res/values/strings.xml , layout files res/layout/*.xml , the generated resource

I'm developing a JavaFX application using IntelliJ IDEA as the IDE. So far, everything runs smoothly, I have all my external libs configured and my JavaFX artifact being correctly created. Now I would like to integrate obfuscation (using Proguard) when the artifact is created. IntelliJ have a 'Pre-processing' and 'Post-processing' option in artifact's properties where I can define an Ant task to be runned. But I have no idea how to create that task and tell the compiler my obfuscation options. Thank you very much in advance for any clues, Best regards There are 3 basic ways you do it: Create a

A common pattern in ProGuard configs for Android applications is to preserve custom View classes, since they are probably referenced only from layout XML instead of application code. Upon project creation, the ADT therefore add these rules to a project's proguard.cfg: -keepclasseswithmembernames class * { public <init>(android.content.Context, android.util.AttributeSet); } -keepclasseswithmembernames class * { public <init>(android.content.Context, android.util.AttributeSet, int); } I guess the idea here is to say that whenever a class defines a constructor that may be called by a layout

I imported several eclipse projects to Android Studio (v1.1). In the original Eclipse environment, they use Proguard for release mode. In the Android Studio environment, this was translated to the following in the build.gradle script (by the import, not by me): buildTypes { release { minifyEnabled true proguardFiles 'proguard.cfg' } } I understand that this means that "in release build, enable Proguard's minify, using proguard.cfg" . The problem, however, is that minify seems to be happening in non-release build (i.e. debug) as well! How is this possible? What is the default for minifyEnabled

I'm creating a build with different flavors with Gradle. It used to run quite good until now, until I wanted to enable Proguard . I enabled minifyEnabled for my Release Build and now I'm having an exception saying : " Caused by: org.gradle.internal.UncheckedException: java.io.IOException: The output jar [.../app/build/intermediates/multi-dex/dev/release/componentClasses.jar] must be specified after an input jar, or it will be empty. " Does anybody know what is causing this exception ? I basically want to enable ProGuard before I release my application. Here is my Gradle file below. lintOptions
