proguard

My project implements a TypeAdapter in Gson during serialization/deserialization for preserving object's polymorphism state. Anyhow, the project works fine during development tests, but when it is released with proguard obfuscation and tested, it just crashes. 03-21 10:06:53.632: E/AndroidRuntime(12441): FATAL EXCEPTION: main 03-21 10:06:53.632: E/AndroidRuntime(12441): java.lang.AssertionError 03-21 10:06:53.632: E/AndroidRuntime(12441): at com.google.gson.internal.bind.TypeAdapters$EnumTypeAdapter.<init>(SourceFile:724) 03-21 10:06:53.632: E/AndroidRuntime(12441): at com.google.gson.internal

My application has many activities and uses native library too. With the default ProGuard configuration which Eclipse generates ProGuard removes many things - OnClick methods, static members, callback methods which my native library uses... Is it there a simple way to instruct ProGuard to NOT remove anything from my package? Removing things saves only about 2.5% of the application size, but breaks my application completely. Configuring, testing and maintaining it class by class in ProGuard configuration would be a pain. I think you need to add these flags at the very least (modify for you

When I got something like this ERROR/AndroidRuntime(18677): Caused by: java.lang.NullPointerException ERROR/AndroidRuntime(18677): at com.companyname.a.a.a(Unknown Source) How can I know where the problem is and debug this issue? I only got the mapping output from ProGuard and don't know the line number. Thanks. Add the following lines to your proguard configuration. -renamesourcefileattribute SourceFile -keepattributes SourceFile,LineNumberTable Now your stack traces will include line numbers, and by using the retrace tool that ships with proguard (included in the Android SDK), you are able

I am getting errors from Crashlytics that indicates that some devices are missing com.google.android.webview.

I'm attempting to add a 3rd party library (JmDNS) to my Android project. I created a folder 'libs' under the base project directory, and dropped the jar file in the directory. When I attempt to build he project using Ant (ant release), I receive a 'duplicate definition' notices for what appears to be each class in the JmDNS jar file. ....

I recently updated android studios to version 2.3, build tools to 25.0.2, gradle 2.3.0 and gradle distribution 3.3 and now i am getting this while building the project. Never had this issue with older versions. * Exception is: org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'. at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:84) at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.execute(ExecuteActionsTaskExecuter.java:55) at org

I am succesfully using proguard for my Android apps. However, with one app I am having trouble. This app uses a java library that has a .xml file that is stored in the package. InputStream istream = Library.class.getResourceAsStream("resource.xml"); This library works great when proguard is disabled. However, running proguard, it seems that the xml file is just completely stripped away. Relevant proguard.cfg -optimizationpasses 5 -dontusemixedcaseclassnames -dontskipnonpubliclibraryclasses -dontpreverify #-dontobfuscate #-repackageclasses '' //THIS IS DISABLED -keepattributes *Annotation*
