当选择释放模式时，应用程序崩溃，但在调试模式下工作正常

Question

我想减小应用程序的大小，因此我在发布模式下使用minifyenabled true，但由于此应用程序崩溃。下面是我的

Build.Gradle

 buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        // replace with the current version of the Android plugin
        classpath 'com.android.tools.build:gradle:1.1.0'
        // the latest version of the android-apt plugin
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
    }
    }

    apply plugin: 'com.android.application'
    apply plugin: 'com.neenbedankt.android-apt'

    apt {
    arguments {
        androidManifestFile variant.outputs[0].processResources.manifestFile
        resourcePackageName android.defaultConfig.applicationId
     }
     }

     android {
     compileSdkVersion 21
     buildToolsVersion "21.1.2"

     defaultConfig {
        applicationId "com.iifl.news.codereduce"
        minSdkVersion 10
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    packagingOptions {

        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'

    }
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'

    }
    }

    dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:21.+'
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile 'com.jakewharton:butterknife:5.0.+'
    compile 'com.jakewharton.timber:timber:2.2.+'
    compile 'com.squareup.dagger:dagger:1.2.+'
    provided 'com.squareup.dagger:dagger-compiler:1.2.+'
    apt 'com.squareup.dagger:dagger-compiler:1.2.2'


    compile 'com.squareup.okhttp:okhttp:2.0.0'
    compile 'com.squareup.okhttp:okhttp-urlconnection:2.0.0'
    compile 'com.squareup.retrofit:retrofit:1.6.1'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.4.+'
    compile 'com.fasterxml.jackson.core:jackson-core:2.4.+'
    compile 'com.fasterxml.jackson.core:jackson-annotations:2.4.+'
    compile 'com.github.satyan:sugar:1.3'
    compile 'com.pnikosis:materialish-progress:1.2'
    compile 'com.android.support:cardview-v7:21.0.3'
    compile 'com.google.android.gms:play-services-analytics:7.0.0'

    compile files('libs/volley.jar')
   }

我添加了proguard-rules.pro。如果我移除它，它会给我多个警告。

-keep class butterknife.** { *; }
-dontwarn butterknife.internal.**
-keep class okhttp.** { *; }
-dontwarn okhttp.**


-keep class retrofit.** { *; }
-dontwarn retrofit.**

-keep class okio.** { *; }
-dontwarn okio.**

-keep class dagger.** { *; }
-dontwarn dagger.**
-dontwarn org.w3c.dom.bootstrap.DOMImplementationRegistry
-dontwarn okio.**
-dontwarn    com.squareup.okhttp.internal.huc.JavaApiConverter$CacheHttpURLConnection
-dontwarn com.squareup.okhttp.internal.huc.HttpURLConnectionImpl

我也尝试过使用-keep class com.iifl.news.codereduce.{*；}-dontwarn com.iifl.news.codereduce.**，但它仍然在发布模式下崩溃，在调试模式下运行良好。

我还尝试在依赖项中添加androidtestapt'com.squareup.dagger:dagger-compiler:1.2.2'。但没有运气

我也有同样的问题。问题是proguard在应用程序启动时删除了未使用的类方法，但应用程序稍后可能需要这些类方法，例如当您切换到其他活动或退出应用程序时，这时应用程序崩溃了。您需要将minifyEnabled属性更改为false，以永久保留未使用的方法。但仍然可以在发布期间使用shrink属性收缩所有文件。缩量可能提振APP业绩。

    release {
        minifyEnabled false //keeps unused methods instead of removing them
        shrinkResources true //to shrink files
        proguardFiles getDefaultProguardFile('proguard-android.txt'),     'proguard-rules.pro'
    }
