Android Studio 1.0.2 "minifyEnabled true"使签名版本 apk 崩溃

Question

升级到 Android Studio 1.0.2 会导致签名的发布 apk 文件在应用程序启动后立即崩溃(调试 apk 工作正常)。

将 **minifiyEnabled 设置为 false ** 可修复签名发布 apk 文件中的崩溃问题。

build.gradle(Module:app) 文件的 buildTypes 部分如下所示

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

行 getDefaultProguardFile 似乎是嫌疑犯，因为 android studio 显示下划线 getDefaultProguardFile 并且当将鼠标悬停在它上面时显示警告 Cannot resolve symbol getDefaultProguardFile.

以下是build.gradle(project)文件

// 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()
    }
}

以下是build.gradle(app)文件内容

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.+'

}

There are some warning in the gradle build

Answer 1

将以下规则添加到您的 proguard-rules.pro 文件中。

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

如果该文件不存在，您可以在 app/proguard-rules.pro 下创建它。请注意，如果您将 Android Studio 设置为“Android” View ，则该文件可能不会显示。您可能需要暂时切换到“项目” View 才能找到它。
