Question

我正在使用Android Studio 1.1.0。构建变体debug工作正常，但是当我尝试运行release构建变体时，应用程序启动但是给了我一个＆＃34;不幸的是，“应用程序名称”已停止。＆＃34;

我过去已经签署了我的应用程序，也许我错过了一个我完全忘记的简单步骤，我错过了什么？

这是我的build.gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"
    defaultConfig {
        applicationId "com.madx.quiz.apf"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }

    signingConfigs {
        release {
            storeFile file('/Users/madx/Documents/Workspaces/Android/APF/app/keystore.keystore')
            storePassword ‘my_store_password’
            keyAlias ‘my_key_alias’
            keyPassword ‘my_key_password’
        }
        debug {}
    }

    buildTypes {
        release {
            signingConfig signingConfigs.release
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            zipAlignEnabled true
        }
        debug {
        }
    }
}

repositories{
// some repositories
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:21.0.3'
    compile 'com.android.support:support-v13:21.0.0'
    compile 'com.google.code.gson:gson:2.3.1'
}

事件日志给了我：

Answer 1

尝试在发布版本中禁用ProGuard：

build.gradle：

buildTypes {
    release {
        signingConfig signingConfigs.release
        zipAlignEnabled true
    }
    debug {
    }
}

问题可能是由ProGuard造成的，但如果没有堆栈跟踪，我无法解决您的问题。

我仍然想使用proguard我建议您查找有关错误的更多信息，您可以在发布字段中添加以下内容：

debuggable true
jniDebuggable true

因此，您可以更好地识别问题。但是，问题可能与gson库有关，您应该在proguard-rules.pro文件中添加以下行（您可以查看更复杂的示例here）：

# Add any classes the interact with gson
-keepclassmembers class com.madx.quiz.apf.apf.APFQuestion { *; }
-keepclassmembers class com.madx.quiz.apf.apf.APFSubCategory { *; }

###---------------Begin: proguard configuration for Gson  ----------
# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default, so configure it to keep all of it.
-keepattributes Signature

# For using GSON @Expose annotation
-keepattributes *Annotation*

# Gson specific classes
-keep class sun.misc.Unsafe { *; }
#-keep class com.google.gson.stream.** { *; }

# Application classes that will be serialized/deserialized over Gson
-keep class com.google.gson.examples.android.model.** { *; }

##---------------End: proguard configuration for Gson  ----------

Android Studio Release版本给了我：不幸的是，“App Name”已停止
