how to use -assumenosideeffects class android.util.Log in my app

Question

I write -assumenosideeffects class android.util.Log in my app. but how to use this.

-assumenosideeffects class android.util.Log 
{
    public static int d(...);
    public static int v(...);
    public static int i(...);
    public static int e(...);
}

in proguard.cfg file. but not working.

Answer 1

The manual says -assumenosideffects is "Only applicable when optimizing".

${sdk.dir}/tools/proguard/proguard-android.txt says: "Optimization is turned off by default. Dex does not like code run through the ProGuard optimize and preverify steps".

Answer 2

According to @Sean Owen and @Yevgen Kulik.

In Gradle, use this:

proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

Then add below to your proguard-rules.pro

-assumenosideeffects class android.util.Log { public * ; }

Answer 3

Try -assumenosideeffects class android.util.Log { public * ; }. If that doesn't work, post why you think it isn't working.

Answer 4

The below one works exactly

-assumenosideeffects class android.util.Log {

public static *** d(...);

}

Similarly you can use i, v and e.

Answer 5

Forgot 'public' access modifier?

-assumenosideeffects public class android.util.Log
