android proguard android-proguard signed-apk

I am trying to use proguard in my app set the proguard to true and then the problem starts I am importing lib when I use proguard by following this -keepnames class com.somepackage.* with my package name the app is getting getting crashed when I try to use the signed apk. I know this iS a dumb question but I am stuck at this for last 5 hr not able to find an easy solution as I am using about 20 lib. I followed this also. Plz guide me in this how can I do this?

This is my proguard rule class code

-keepnames class beatbox.neelay.dummybeat.*
-keepnames com.srx.widget.*
-keepnames de.hdodenhof.circleimageview.CircleImageView.*
-keepnames com.bumptech.glide.*
-keepnames com.romainpiel.shimmer.*
-keepnames com.vansuita.gaussianblur.GaussianBlur
-keepnames com.antonyt.infiniteviewpager.InfinitePagerAdapter
-keepnames com.antonyt.infiniteviewpager.InfiniteViewPager
-keepnames com.eftimoff.viewpagertransformers.CubeOutTransformer
-keepnames com.ms.square.android.glassview.GlassView
-keepnames me.alexrs.fontpagertitlestrip.lib.FontPagerTitleStrip

I am not able to generate any signed apk now . the error is.

Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'.

Job failed, see logs for details

any hint will be helpful. console output

Editing build.gradle

apply plugin: 'com.android.application'

log don't show any thing bro that's the issue otherwise i added almost every thing – Detach 17/5, 2017 at 18:45

the data is getting loaded from the system but then the app crash with no log – Detach 17/5, 2017 at 18:45

Do you have the right console visible? – Lorenzo 17/5, 2017 at 18:46

see the update question sorry i dont getting in the starting now i do know.plz guide me – Detach 17/5, 2017 at 18:52

Run ./gradlew --stacktrace :app:transformClassesAndResourcesWithProguardForRelease and see what you get there. – Softa 20/5, 2017 at 11:25

Can you tell me how to properly set the proguard for the class it will be helpful – Detach 20/5, 2017 at 12:53

Please show your full proguard and build.gradle files. Generally this issues occurs due to some libraries or classes in your project – Purism 22/5, 2017 at 10:42

@HarisQureshi see the question now – Detach 22/5, 2017 at 12:20

Try to change all support lib to same version 25.2.0 or 25.1.0 . you are using both right now – Illbred 22/5, 2017 at 12:29

Can you provide complete stacktrace as well – Illbred 22/5, 2017 at 12:31

when i used the first proguard rule it throw an error during apk build but when i run the proguard withe the new rules it dont show any error .But when testing the apk it crash. – Detach 22/5, 2017 at 12:34

You can consider DexGuard, it's more secure & easy to integrate according to them. From makers of proguard. – Ecumenism 25/5, 2017 at 9:23

thx sir let me try that one also .@Ecumenism will i have to set the library like in proguard also?? – Detach 25/5, 2017 at 9:32

Reason : Not every Class or Library are optimized with Proguard enabled , So what Proguard do is that it removes classes if they are not optimize which results crash and bugs in project.

Solution : In your proguard.cfg file keep that classes or library which are not supported by progaurd . Try the catch all described here :
Try adding :

-keep class android.support.v7.internal.** { *; }
-keep interface android.support.v7.internal.** { *; }
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }

Or , if you are using v4 lib :

-dontwarn android.support.v4.**
-keep class android.support.v4.** { *; }
-dontwarn android.support.v7.**
-keep class android.support.v7.** { *; }

If you are using latest android studio you might found this as proguard-rules.pro

In your case try using -dontwarn as well with classname. Like your error show that it can not optimize circleimageview Library . so try to add this as well :

-dontwarn hdodenhof.**
-keep class hdodenhof.**

If still not working than downgrade your circleimageview library :
compile 'de.hdodenhof:circleimageview:1.3.0' This is working for me.

sir will i have to declare the lib that is used only in xml form like card view lib and other library – Detach 26/5, 2017 at 14:8

sir i added the dependency tree can you plz check it now – Detach 26/5, 2017 at 15:53

@Detach Yes you have to if it is not optimized by Proguard .. it will give you some warning about your library in logs .. It doesn't matter you are using it in your xml or classes , it will get compiled along with other classes and library . – Alkane 27/5, 2017 at 5:48

bhai i tried as you said but it is still getting crashes when running as you said can tell me how to declare the lib here is my dependency tree gist.github.com/neelayak/ef0fa83f9397c34eac0ac9cf60aa02a3 – Detach 27/5, 2017 at 16:53

1) Keep all annotations

-keepattributes SourceFile,LineNumberTable,*Annotation*,EnclosingMethod,Signature,Exceptions,InnerClasses

2) Keep if you have any pojos or models and classes which are using for network call

Ex:

-keep class com.example.android.models.**
-keepclassmembers class com.example.android.models.** {
      *;
}
-keepclassmembers class com.example.android.network.** {
  public void set*(***);
  public *** get*();
  public *** is*();
}

3) For all the libraries you are using keep below proguard rules

Ex:

-dontwarn com.zl.reik.dilatingdotsprogressbar.**
-keep class com.zl.reik.dilatingdotsprogressbar.**{*;}
-keep interface com.zl.reik.dilatingdotsprogressbar.**{*;}

You even need to keep similar proguard rules for "foldingtabbar", as It is also a library

If the above solution does not solve, run ./gradlew app:dependencies in your repository and Send me the list of dependencies

sir i added the dependency tree can you plz check it now – Detach 26/5, 2017 at 15:54

Having the same version for all the support libraries is also very important. Sometimes libraries have recursive dependencies, where each has a different version which can lead to this error. Run:

./gradlew app:dependencies

to see the dependencies for each library and check whether they all have the same version. I already see, that you use 25.1.0 and 25.2.0 versions of support libraries. In addition, some of your libraries are old, thus, they probably use old versions.

Try to use:

-keep class beatbox.neelay.dummybeat.**{*;}
-dontwarn beatbox.neelay.dummybeat.**

instead of:

-keepnames beatbox.neelay.dummybeat.**{*;}

Sir where i have to use ./gradlew app:dependencies i tried to find it in console gradel but not able to find – Detach 24/5, 2017 at 12:59

navigate to your project folder with cmd (command line) and run the command – Multiple 26/5, 2017 at 11:28

Sir i tried but it is still getting crashed can you give me a sample from my dependency tree gist.github.com/neelayak/ef0fa83f9397c34eac0ac9cf60aa02a3 – Detach 27/5, 2017 at 17:18

Proguard removes classes which are part of dependencies added the app. Try to keep them using:

-keep class hdodenhof.**
-keep class android.support.v4.** { *; }
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }
-keep class android.support.v7.internal.** { *; }
-keep interface android.support.v7.internal.** { *; }

Disable warning for dependency classes:

-dontwarn hdodenhof.**
-dontwarn android.support.v4.**
-dontwarn android.support.v7.**

Where should I add this? – Ivoryivorywhite 5/9, 2018 at 4:41

@Ivoryivorywhite You should add these in app/proguard-rules.pro file – Eldridgeeldritch 5/9, 2018 at 6:3

I did but I still get this error Execution failed for task ':app:transformClassesAndResourcesWithProguardForRelease'. The error has started to occur after I added maven { url "jitpack.io" } to build.gradle which is required for react-native-spark-button. Can you please guide how I can resolve this? – Ivoryivorywhite 5/9, 2018 at 6:46
