Android Proguard doesn't shrink APK

Title sums it up - my app is the same size installed on the device with and without Proguard and the APK is the same size on disk. I unzipped the APK and the dex files account for about 72% of it, so minifying should have a significant effect (unless I'm using every class and method from every dependency I've included, which is not plausible). I'm using the standard rules file plus one of my own with a few keep rules.

Gradle file:

release {
            signingConfig signingConfigs.release
            zipAlignEnabled true
            minifyEnabled true
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }

proguard-rules.pro:

-dontwarn retrofit.**
-keep class retrofit.** { *; }
-keepattributes Signature
-keepattributes Exceptions

I thought there would be a ton of information about this problem but as far as I can tell there's almost nothing.

Use proguard-android-optimize.txt and not proguard-android.txt as the base proguard config file.

The first one configures both obfuscation and optimization while the latter configures only obfuscation.

minifyEnabled true: it runs ProGuard

shrinkResources true: it removes resources that ProGuard flagged as unused.

While removing unwanted files from your DEX, your APK size also reduces.
