使用ProGuard轻松破解

我的应用程序正常工作 without ProGuard，即minifyEnabled为false

但是当我将minifyEnabled变为 true 时，应用程序开始崩溃 .

我使用的是Android Studio（v1.4.1）和Gradle（com.android.tools.build:gradle:1.3.0）

Note: I have placed Smack Jar in /libs folder

build.gradle

dependencies {
   compile fileTree(include: ['*.jar'], dir: 'libs')
   compile 'com.android.support:appcompat-v7:23.1.0'//23.0.1
   compile 'com.android.support:design:23.1.0'//23.0.1

   //_____________3rd party
   compile 'joda-time:joda-time:2.8.2'
   compile 'org.jxmpp:jxmpp-core:0.4.1'
   compile 'org.jxmpp:jxmpp-util-cache:0.4.1' 
   compile 'de.measite.minidns:minidns:0.1.1'
   compile 'org.apache.httpcomponents:httpcore:4.3.2'
   compile 'org.apache.httpcomponents:httpmime:4.3.5'

   //_____________library jars
