我想减少应用程序的大小，因此我在发布模式下使用minifyEnabled true，但由于此应用程序崩溃。以下是我的
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 {

}

}
}
packagingOptions {

我添加了proguard-rules.pro。如果我删除它，那么它会给我多个警告。

我认为是由于proguard。但我没有弄到我做错了什么。任何消化不良将不胜感激。提前致谢
Folllowing是我的logcat：应用程序在运行后立即崩溃。

我还尝试过使用-keep class com.iifl.news.codereduce.{ *; }
-dontwarn com.iifl.news.codereduce.**但仍然处于发布模式，它崩溃并且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

我遇到了同样的问题。问题是proguard是在应用程序启动时删除未使用的类方法，但是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，那就是应用程序崩溃的时候。您需要将minifyEnabled属性更改为false以永久保留未使用的方法。但是仍然可以使用shrink属性在发布期间缩小所有文件。缩小可能会提升应用程序的性能。
release {
minifyEnabled false //keeps unused methods instead of removing them
shrinkResources true //to shrink files
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}

如果您使用的是Retrofit，我假设您将使用将作为POJO转换为JSON的类。 （即Retrofit返回响应时创建的Java对象）
这些类应该
-keep class com.app.example.{ *; }
-dontwarn com.app.example.**

从apt 'com.squareup.dagger:dagger-compiler:1.2.1文件中删除build.gradle。
