添加Google Analytics后无法生成APK,但在调试模式下正常运行

Question

这是一个非常奇怪的情况.我可以构建我的项目,清理和构建我的项目,甚至可以在具有调试模式的物理设备上运行.我还获得了Google Analytics网页上所需的所有数据.

可悲的是,Android Studio没有生成发行版,.apk文件.我完全按照向您的Android应用程序添加分析,官方教程,并搜索了许多答案,但确切的问题仍然存在.

我的build.gradle看起来像这样:

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"

    defaultConfig {
        applicationId "com.comname.appname"
        minSdkVersion 11
        targetSdkVersion 23
        versionCode 18
        versionName "2.7"
    }
    buildTypes {
        release {
            minifyEnabled true
            zipAlignEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}


dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile files('libs/achartengine-1.1.0.jar')
    compile files('libs/SalatCalculator.jar')
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.android.support:support-v4:23.0.0'
    compile 'com.google.android.gms:play-services-analytics:7.8.0'
}

这是Gradle Build报告:

另外Note: D:\D\AndroidStudio\AppName\app\src\main\java\com\comname\AppName\util\NotificationGenerator.java uses or overrides a deprecated API.,我已经为这个文件运行了Lint,它没有显示任何这样的警告.

问题与proguard相关,您只在发布配置文件(minifyEnabled true)上激活了proguard .

您有两种选择:

1. 禁用Proguard将此属性设置为 false.如果您要发布应用程序,则不建议使用此选项.

2. 将规则添加到Proguard以正确使用Google Analytics.应将此规则添加到文件中proguard-rules.pro,这是一个示例:

   -keep class com.google.android.gms.** { *; }
   -dontwarn com.google.android.gms.**
   

有关Proguard的更多信息,请参阅Android开发者页面和官方项目页面的

希望能帮助到你.
