I have a test project developed in UiAutomator, which is not specific for one app, i.e., I don't even have any application associated to my test. My main folder only has the AndroidManifest, my code is all in the test folder.
I want to make my code available but ofuscated. So I want to obtain an APK of my code obfuscated.
My build.gradle contains
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
testProguardFiles('proguard-rules.pro')
}
debug{
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
testProguardFiles('proguard-rules.pro')
debuggable true
}
}
and proguard-rules.pro file is:
-keep public class * extends android.test.InstrumentationTestCase
-keep public class * extends junit.framework.TestCase
-keep public class * implements junit.framework.TestCase
-keep class android.support.** { *;}
-keep interface android.support.** { *;}
-keep public class junit.framework.** { *;}
-keep class android.uiautomator.** { *;}
-keep class com.impactToolTester.utility.Constants
-keepclasseswithmembernames class *{
public <init>(java.lang.Class,android.support.test.internal.util.AndroidRunnerParams);
}
-dontnote android.support.test.internal.runner.listener.CoverageListener
-dontwarn android.test.**
-dontnote org.junit.**
-dontnote junit.runner.*
-dontnote junit.framework.*
-dontnote android.net.**
-dontnote org.apache.http.**
When I run gradlew assembleAndroidTest the app-debug-androidTest-unaligned.apk is created in build/outputs/apk.
However, when I decompile the apk I realise it's not obfuscated at all. I know the proguard file is read because I started with several errors when I first run it.
I have the minifyEnabled in both debug and release because I'm not sure which is run with assembleAndroidTest.
I'm a real newbie when it comes to proguard and obfuscation in general so any help would be much appreciated.

I connected FCM and tested before. And it worked fine.
However, I am ready to publish my app and enabled proguard in build.gradle
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt')
proguardFile 'proguard-rules.pro'
}
debug {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt')
proguardFile 'proguard-rules.pro'
// proguardFile 'proguard_debug.pro'
}
}
And applied this in proguard-rules.pro:
-keep class com.firebase.** { *; }
-keepnames class com.fasterxml.jackson.** { *; }
-keepnames class javax.servlet.** { *; }
-keepnames class org.ietf.jgss.** { *; }
-dontwarn org.w3c.dom.**
-dontwarn org.joda.time.**
-dontwarn org.shaded.apache.**
-dontwarn org.ietf.jgss.**
-dontwarn com.firebase.**
-dontnote com.firebase.client.core.GaePlatform
Everyone get push messages but just my test phone doesn't receive them which is proguard enabled. I converted my data models to Serialize format. But now this problem is happening.
How can I use FCM or other Firebase features such as Remote Config or Crashlystics?
Obfuscation renames variables in Kotlin data class without #SerializedName and as result Json not parsing to model class.
To prevent this you can use #Keep annotation
#Keep
data class MyClass(...)
or set #SerializedName to all values
I've been facing this problem for weeks now and I still can't get it to work.
First of all I am using data binding for my project and it all runs smoothly without any runtime crashes using Android Studio's ADB. Even when I generated a signed "debug" APK for testing, it runs smoothly as well, until I set minifyEnabled to "true" on the debug and exported the APK (debug) out and it crashes.
So, I'm pretty sure there's something to do with Proguard optimising my classes / files.
Here is my app module :
buildTypes {
debug {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
So, to sum it up. When I change the debug's "minifyEnabled" to "false" and export the APK and test it on my phone, it runs fine.
But when I change it to "true", it crashes on runtime.
I've already added '-keep class' and '-dontwarn' in my proguard file.
Here it is :
-dontwarn android.databinding.**
-keep class android.databinding.** { *; }
-keep class android.databinding.annotationprocessor.** { *; }
-dontwarn android.viewmodel.**
-keep class android.viewmodel.** { *; }
-dontwarn android.support.v4.**
-keep class android.support.v4.** { *; }
-dontwarn android.support.v7.**
-keep class android.support.v7.** { *; }
-dontwarn android.support.design.**
-keep class android.support.design.** { *; }
-keep interface android.support.design.** { *; }
-keep public class android.support.design.R$* { *; }
-keep class java.lang.** { *; }
My project runs Crashlytics and I've seen the error of the crash, which points to the databinding class. But I've already told proguard to keep the class as stated above.
I'm not sure what I'm missing here, this is the error I'm getting from Crashlytics :
com.myproject.android.databinding.ItemProductDataBinding.executeBindings (Unknown Source)
How do I know which class Proguard is helping to optimise and which class isn't? Hope you guys have the answer, and save me another few weeks of headaches. Thanks for reading.
I have a payment application with payumoney integration. It was working fine until i added the proguard. Recently I have added Proguard to my build.gradle file (Module: app)
` buildTypes {
release {
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
signingConfig signingConfigs.config
}
}`
After this App gets closed when i proceed to payment. It is working fine when i Changed minifyEnabled to false.
Following is my Module:PayuMoneySdk Build.gradle File
`buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}`
How can I solve this issue? I can't disable proguard.
Can I enable proguard to only Module:app? And will it solve the issue?
I am new to programming. Please help!!
The solution is to look up for the methods and classess that needs to be exempted and add them to the proguard rules as follows..
-keep class com.mm.** {*;}
-keep class com.company.** {*;}
-keepclassmembers class com.mm.** {*;}
-keepclassmembers class com.company.** {*;}
add below lines in proguard-rule.pro file
-dontwarn okio.**
# Platform calls Class.forName on types which do not exist on Android to determine platform.
-dontnote retrofit2.Platform
# Platform used when running on Java 8 VMs. Will not be used at runtime.
-dontwarn retrofit2.Platform$Java8
# Retain generic type information for use by reflection by converters and adapters.
-keepattributes Signature
# Retain declared checked exceptions for use by a Proxy instance.
-keepattributes Exceptions
-keep class com.** { *; }
I'm trying to obfuscate my code using ProGuard, but I still get error even using default proguard-rules.txt:
I really could not find anything about this. Since I'm new to ProGuard, can you help me solving this issue?
My gradle.build file is the following:
buildTypes {
release {
debuggable false
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
debug {
debuggable true
minifyEnabled false
shrinkResources false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
}
}
And the proguard-rules.txt:
# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose

# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).

# Note that if you want to enable optimization, you cannot just
# include optimization flags in your own project configuration file;
# instead you will need to point to the
# "proguard-android-optimize.txt" file instead of this one from your
# project.properties file.

}

-keep class android.support.annotation.Keep
-keep #android.support.annotation.Keep class * {*;}
-keepclasseswithmembers class * {

}
-keepclasseswithmembers class * {

}
I always use *.pro for proguard files. Try to change *.txt to *.pro.
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
Looking at the logs pointed me to the right direction.
The problem was a silent error in XML layout, in fact I had a button with android:onClick="" attribute and the argument was empty.
I think ProGuard generated a method with empty method name and this caused the problem.
I am trying to test my app which has passed the 64K limit.
I have set minify on but it doesn't work when debuggable is enabled. However, if I build a version with debuggable off then it shrinks it by 2/3!
Am I missing something? This is the relevant part of my Gradle file:
buildTypes {
release {
minifyEnabled true
debuggable false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
minifyEnabled true
debuggable true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
proguard-rules.pro:
-keep class .R
-keep class **.R$* {
<fields>;
}
-keepattributes *Annotation*
-keepclassmembers class ** {
#org.greenrobot.eventbus.Subscribe <methods>;
}
-keep enum org.greenrobot.eventbus.ThreadMode { *; }
-keepclassmembers class * extends org.greenrobot.eventbus.util.ThrowableFailureEvent {
<init>(java.lang.Throwable);
}

With proguard enabled your code gets obfuscated and debugging will not be possible. That is why when you want to debug and set the flag true, proguard does not activate and that is why you do not see the minification of your apk.
