FileNotFoundException on proguard-rules.pro file

Question

I\'m using Android Studio v.1.0 My build file :

  buildTypes {

    debug {
        minifyEnabled false
        proguardFiles getDefaultProguardFile(\'prog         


        

Answer 1

If you don't need any specific ProGuard configuration:

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt')
    }
}

(The warning might happened)

Or specify "rules" and put it here:

.../app/proguard-rules.pro

For example I use "Butter Knife" and my proguard-rules.pro looks like:

-keep class butterknife.** { *; }
-dontwarn butterknife.internal.**
-keep class **$$ViewInjector { *; }

-keepclasseswithmembernames class * {
    @butterknife.* ;
}

-keepclasseswithmembernames class * {
    @butterknife.* ;
}

Or, possibly you can leave build.gradle file as it is (if you don't like warnings )), And just put an empty proguard-rules.pro to that location.
