how to avoid method parameters from obfuscation?

Question

How to avoid the following method name from obfuscation?

public static void testClassMethod(String testVaiable1,Stringtestvariable2) {
    System.out.println( testVaiable1);
}

but after obfuscating my method was

TestClass.testClassMethod(s:"abc", s1:"pqr");

my proguard file contains the following rules

-keep class com.example.mylibrary.TestClass**
-keepclassmembers class com.example.mylibrary.TestClass** 
 {*;}
-keep class com.example.mylibrary.TestClass{
    public void 
        testClassMethod(java.lang.String,java.lang.String);
}

Try this

-keepnames class com.yourPackage.TestClass
-keepclassmembernames class com.yourPackage.TestClass {
    public <methods>;
    public <fields>;
    #!private *; 
}

edit Try this:

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose

-keep, allowobfuscation class com.YOURPACKAGE.*
-keepclassmembers, allowobfuscation class * {
    *;
}

-keepnames class com.YOURPACKAGE.YOURCLASS
-keepclassmembernames class com.YOURPACKAGE.YOURCLASS {
    public <methods>;
    public <fields>;
    #!private *;
}

Did you replace "yourPackage"? – Blnpwr Aug 27 '19 at 13:25
yes. -keepnames class com.example.mylibrary.TestClass -keepclassmembernames class com.example.mylibrary.TestClass { public ; public ; #!private *; } – sonali parab Aug 27 '19 at 13:28
Are you sure you did not miss anything? Because for my test class everything works. What is your gradle version? – Blnpwr Aug 27 '19 at 13:54

update android studio and added the following two lines into proguard file

  -keep class com.example.mylibrary.TestClass{*;} - 
   keepparameternames

The above solution works for me.
