Android Studio 1.0.2 "minifyEnabled true" crashes the signed release apk

Question

Upgrading to Android Studio 1.0.2 causes the signed release apk file to crash as soon as the application is launched(debug apk works fine).

Setting the **minifiyEnabled to false ** fixes the crash in the signed release apk files.

The buildTypes section of the build.gradle(Module:app) file looks like below

   buildTypes {
        release {
            minifyEnabled  false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }

The line getDefaultProguardFile seems to be the suspect since the android studio shows underlines the getDefaultProguardFile and when hovered over it shows warning Cannot resolve symbol getDefaultProguardFile.

The following is the build.gradle(project) file

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

The following is the build.gradle(app) file contents

apply plugin: 'android'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 9
        targetSdkVersion 17
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled  false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:+'
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.gms:play-services:6.1.+'

}

Update 1:

There are some warning in the gradle build

Configuration on demand is an incubating feature.

Answer 1

Add the following rules to your proguard-rules.pro file.

-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
-keep class android.support.v7.app.** { *; }
-keep interface android.support.v7.app.** { *; }

If the file doesn't exist, you can create it under app/proguard-rules.pro. Note that the file may not show up if you have Android Studio set to the "Android" view. You may need to temporarily switch to the "Project" view to find it.
