Android Proguard "can't Find Referenced"

I want to generate a signed apk. But I reached the 64k methods limit so I searched for some solutions and one of them is to use proguard. I edited my build.gradle like this: build

Solution 1:

There are two problematic libraries:

RoundCornerProgressBar

MPAndroidChart

The first problem is with the class com.akexorcist.roundcornerprogressbar.TextRoundCornerProgressBar. There is a solution here that overcomes the problem, by adding to Proguard:

-dontwarn com.akexorcist.roundcornerprogressbar.TextRoundCornerProgressBar

The second one is simply solved by adding two statements to Proguard that the author of the library clearly describes here:

-keep class com.github.mikephil.charting.** { *; }-dontwarn io.realm.**

Your Proguard file should contain those lines and the problems should disappear.

Solution 2:

buildTypes {

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


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