Use Proguard only to disable logging and for shrinking resources

build.gradle: 

buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.SginConfig
        }
}

I don't want Proguard to optimize, or obfuscates my code as it is causing me a lot of trouble. I only want to remove log calls and enable shrinking of unused resources.

proguard-rules.pro:

-assumenosideeffects class android.util.Log {
    public static boolean isLoggable(java.lang.String, int);
    public static int w(...);
    public static int d(...);
    public static int e(...);
}

Adding the code above to proguard-rules.pro work only if I set getDefaultProguardFile from ('proguard-android.txt') to ('proguard-android-optimize.txt')

But by setting it to proguard-android-optimize.txt would enable optimization flags which I don't want in my case.

So how can I just disable logging and shrink resources without Proguard's doing any minifying or optimizations to my code?

You should be able to do this by only enabling the specific Proguard optimizations that assumenosideeffects depends on. The two that it depends on are:

  • code/removal/simple: Removes dead code based on a simple control flow analysis.
  • code/removal/advanced: Removes dead code based on control flow analysis and data flow analysis.

You can read more about the different optimization options here. So something like this should work:

proguard-rules.pro

-optimizations code/removal/simple,code/removal/advanced
-dontobfuscate
-assumenosideeffects class android.util.Log {
    public static boolean isLoggable(java.lang.String, int);
    public static int w(...);
    public static int d(...);
    public static int e(...);
}

build.gradle

buildTypes {
        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.SginConfig
        }
}

I think you can still try using options like -dontobfuscate & dontshrink in your proguard configuration file. These options will not shrink and obfuscate the code.
