Android Can'；添加Google Analytics后不会生成APK，但在调试模式下工作正常

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，甚至可以使用调试模式在物理设备上运行。我还可以在Google Analytics网页上获得我需要的所有数据

令人遗憾的是，Android Studio没有生成发布版本.apk文件。我完全遵循了官方的教程，也搜索了许多答案，但确切的问题仍然存在

我的build.gradle如下所示：

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'
}

同样关于

注意：D:\D\AndroidStudio\AppName\app\src\main\java\com\comname\AppName\util\NotificationGenerator.java使用或覆盖了不推荐使用的API。

，我已经为此文件运行了Lint，但它没有显示任何此类警告。

问题与proguard相关，您只在发布配置文件时激活了proguard（

minifyEnabled true

）

您有两个选择：

禁用Proguard将此属性设置为

false

。如果要发布应用程序，则不建议使用此选项

将规则添加到Proguard以正确使用分析。应将此规则添加到文件

Proguard rules.pro

，以下是一个示例：

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

和中有关Proguard的更多信息

希望有帮助。

还有一个解决方案，在谷歌解决问题之前，我更喜欢它。 您可以添加缺少的类，并且不必担心可能会出现某些ClassNotFoundException

因此，只需将其添加到gradle配置中：

android {
     useLibrary 'org.apache.http.legacy'
}

---

您建议这两个选项中的哪一个？另外，现在生成了.apk文件，我看到文件大小几乎增加了1MB。可以吗？1MB的增加是因为您选择了禁用选项，对吗？这是有意义的，因为Proguard还删除了未使用的代码，并进行了其他优化以减少apk大小不，我没有禁用它。我有选择选项2。我猜这是因为谷歌分析增加了代码？
