I am using proguard to obfuscate my code in Android Studio. I have deleted many classes from my project and do not use them but proguard warns me about those deleted classes. If i don't use proguard, the app compiles fine.

I tried Invalidate Caches/Restart option but made no difference.

Here are the warnings :

Here is the proguard related part in build.gradle :

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'),
                    'proguard-rules.pro'
        }
    }

Here is proguard-rules.pro file : 

-verbose

-dontwarn android.support.**

-keep class -verbose

-dontwarn android.support.**

-keep class -verbose

-dontwarn android.support.**

-keep class com.mypack.myapp.R { 
*;
}

#below commands for including the line numbers in traces
-renamesourcefileattribute SourceFile    
-keepattributes SourceFile,LineNumberTable.R { 
*;
}

For anyone having the same problem, the problem is solved by simply deleting the entire build folder.
