Question

我将从 android studio 生成签名的apk，我正在尝试减少.apk文件大小。所以从某个地方我得到了使用Progaurd的解决方案，为此我必须在< strong> build.gradle 文件。更改是make ＆＃34; minifyEnabled true＆＃34; 而不是＆＃34; minifyEnabled false＆＃34; 。这是build.gradle文件代码

apply plugin: 'com.android.application'

1android {
compileSdkVersion 22
buildToolsVersion "22.0.1"

defaultConfig {
    applicationId "com.rahu.createsomething"
    minSdkVersion 9
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'),   'proguard-rules.pro'
      }
   }
}

 dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
  compile 'com.android.support:appcompat-v7:22.1.1'
}

现在的问题是当我制造＆＃34; minifyEnabled为真＆＃34;我将文件大小减少1.47 GB到0.97 MB。但是，当我运行该apk文件时，它显示错误消息＆＃34;不幸的是关闭应用程序＆＃34;。

当使用＆＃34; minifyEnable false＆＃34;生成apk时然后它生成1.47 GB .apk文件，它工作正常。但我想要0.97 MB的apk这样我怎么能生成它？

这是我的错误logcat消息

你能把详细的堆栈跟踪...我想问题是由于proguard优化。

有时候如果你使用外部库/ jars proguard会导致问题。

此外，如果您通过反射调用代码（代码中引用的类未在其他任何地方引用）并且proguard工具已删除该特定类，则您可能在运行时遇到异常。

有多种方法可以配置proguard - http://developer.android.com/tools/help/proguard.html#configuring
