App crash if enabled proguard

If enable proguard in my application with this code:

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

Application crash only if published in Play Store when try to run in Debug or Normal mode from Android Studio applcation not crash.

Error when crash:

Error inflating class android.support.v7.widget.Toolbar

Caused by: android.view.InflateException: Binary XML file line #0: Binary XML file line #0: Error inflating class android.support.v7.widget.Toolbar

 Caused by: android.view.InflateException: Binary XML file line #0: Error inflating class android.support.v7.widget.Toolbar

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.widget.aj.a()' on a null object reference

I m using latest version for support.v7:

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:27.0.2'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.android.support:support-v4:27.0.2'
    implementation 'com.google.firebase:firebase-messaging:11.8.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'      
}

Before today all working fine =(

Dexter say:

-dontwarn android.support.v7.**
-keep class android.support.v7.widget.** { *; }

and it work but why after any update of android studio i have always problem?? Why Android Studio after latest version of today proguard cancel widget?

Try adding in Gradle:

android {  
    defaultConfig {  
        vectorDrawables.useSupportLibrary = true  
    }
}

And perform a full clean and rebuild of all the project.

Maybe proguard removes this class, you can disable proguard to avoid this error if you want keep it you will have to change proguard settings

-dontwarn android.support.v7.**
-keep class android.support.v7.widget.** { *; }
