Using -keep does not keep methods and fields. They are obfuscated but I do not want to obfuscate some classes with methods and fields.
Rules used
-target '11'
-keep public class com.example.MyClass
If I use and proguards returns a class which Java Decompiler can not decompile (message 'Internal Error' after decompiling) e.g.
-keep public class com.example.MyClass {
<methods>;
<fields>;
}
I tried also [*;}.
Is there something wrong/bug with ProGuard Version 7.3.0 and using option target '11'?
-keep interface com.example.ApiContext { *; }
-keep abstract class com.example.ControlContext { *; }
-keep class com.example.CloseInstanceContext { *; }
I think 'abstract' was the problem, that it did not work.

In order to configure proguard to keep all classes from a single package, say org.myorg.special, the following notation works:
-keep class !org.myorg.special { *; }
I would like to configure proguard to keep all classes except when they are from either of two packages, say org.myorg.special and org.myorg.another.
I have tried for instance
-keep class !(org.myorg.special,org.myorg.another) { *; }
but the above syntax is not supported by proguard.
What is the correct syntax?
-keep class ![org.myorg.special,org.myorg.another],org.** { *; }
I am using an external library(Picasso) from Jcenter in my Android application. I am implementing an interface of that library in my app. The problem is that proguard always strips the methods of the implemented interface in my app.
The interface defined in the external library is
public interface Callback {
void onSuccess();
void onError();
}
And i implement this interface in my code. When i run proguard and check my .class files, i find that there are no onSuccess and onError methods in my implemented class.
I have already added the configurations to skip all that external library completely in my proguard file by adding this
-keep class com.squareup.picasso.** {*;}
-dontwarn com.squareup.picasso.**
One way of preventing the above stripping is that i do this, where PicassoCallback is my implementation of Callback interface
-keep class com.package.className$PicassoCallback{
public void onSuccess();
public void onError();
}
But then i will have to do this for every implementation of the external interface in my project.
Any proguard configuration that can help me to prevent stripping the methods throughout my project?
You can configure ProGuard to keep all classes that implement the Callback interface using this rule:
-keep class ** implements com.squareup.picasso.Callback { *; }
Another way is to add the #Keep annotation to all of you callbacks, which basically tells ProGuard to not strip/modify them in any way.
Just add this line:
-keep interface com.squareup.picasso.** { *; }
after this one:
-keep class com.squareup.picasso.** {*;}
I use several squareup libs so I have the next configuration in my project:
-keep class com.squareup.** { *; }
-keep interface com.squareup.** { *; }

Hi I am struggling to create release version for my project. I have been try lot of things on Progaurd through SO / Google help but I am still not able to create the release version.
Can somebody help me with this? I always get this issue:

-ignorewarnings
You wouldn't have to specify any package like com.viewpagerindicator.** , this will suppress all warnings and the Gradle Console will just say like :
......
Warning: there were 4 unresolved references to classes or interfaces.
You may need to add missing library jars or update their versions.
If your code works fine without the missing classes, you can suppress
the warnings with '-dontwarn' options.
(http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)
Warning: there were 2 unresolved references to library class members.
You probably need to update the library versions.
(http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedlibraryclassmember)
Note: you're ignoring all warnings!
Ignoring unused library classes...
Original number of library classes: 4237
Final number of library classes: 1317
Printing kept classes, fields, and methods...
Shrinking...
......
In your ProGuard file add:
-dontwarn com.viewpagerindicator.**
If you open up the link you provided and search for 'Warning' about two thirds down you can see the message:
Warning:com.viewpagerindicator.LinePageIndicator: can't find referenced method 'float ceil(float)' in library class android.util.FloatMath
If there are any warnings ProGuard will stop and ask you to fix them first or if your code works you can choose to ignore them with dontwarn.
Update 05/01/2017
If the warning says in program class it is likely that your compiled class files are inconsistent, try removing them all and and rebuilding your project.
If the warning says in library class your compiled class files are inconsistent with the libraries. Try recompiling the class files or upgrading the libraries to consistent versions.

What has helped me was to update all dependencies to last version.
In my case, the proguard file was totally ignored because the project consisted of several modules. According to this answer, the solution was to set the following in the gradle of the module causing the problem:
defaultConfig {
consumerProguardFiles 'proguard-rules.txt'
}
This seems to include the proguard of the module in the application's proguard. Now my dontwarn statements are taken in consideration.
How can I inlcude some of the packages after I excluded the parent package in proguard.cfg:
Ex:
-keep com.myapp.** { *; }
I want proguard to obfuscate com.myapp.data.** { *; }
You can use ProGuard-style regular expressions for the class name:
-keep class !com.myapp.data.**,com.myapp.** { *; }
I have an app that uses ActiveAndroid, a database ORM library, that relies on annotations.
#Table(name="test")
public class DatabaseItem extends ActiveRecordBase<DatabaseItem> {
public DatabaseItem(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
#Column(name="counter")
public int counter;
}
How do I get Proguard working nicely with this? Currently, I get errors about not finding a column name by ActiveAndroid when using Proguard. I guess it somehow mangles the annotation.
My relevant Proguard configuration:
#ActiveAndroid
-keep public class com.activeandroid.**
-keep public class * extends com.activeandroid.ActiveRecordBase
-keepattributes Column
-keepattributes Table
Column and Table aren't existing java class file attributes. You'll at least have to specify
-keepattributes *Annotation*
Cfr. the ProGuard manual.
In March 2013, Proguard version 4.9 was released, one of the fixes were:
Fixed overly aggressive shrinking of class annotations.
So make sure that your Proguard version is up to date and then use Eric Lafortune's solution:
-keepattributes *Annotation*
You can also use this configuration to store all class members that has a specific annotation:
-keepclassmembers class * {
#fully.qualified.package.AnnotationType *;
}
Solution was to keep all members of the library and the database classes
-keep class com.activeandroid.**
{
*;
}
-keep public class my.app.database.**
{
*;
}
-keepattributes Column
-keepattributes Table
For those only using Gradle, the solution is very similar (note the single quotes around the Annotation):
keep 'public class java.package.** { *; }'
keepattributes '*Annotation*'
This is especially useful if you are using JSON serialization annotations (e.g., Jackson or the like) in a vanilla Gradle project.
This what worked in my case:
-keep class com.activeandroid.** { *; }
-keep class com.activeandroid.**.** { *; }
-keep class * extends com.activeandroid.Model
-keep class * extends com.activeandroid.serializer.TypeSerializer
-keep public class * extends com.activeandroid.ActiveRecordBase
-keepattributes Column
-keepattributes Table
-keepattributes *Annotation*
-keepclasseswithmembers class * { #com.activeandroid.annotation.Column <fields>; }
