Smack引发“ NoClassDefFoundError：无法解析以下文件：Lorg / jxmpp / util / XmppStringUtils”
我的应用程序出现问题，我想创建一个连接到服务器的简单XMPP客户端。启动应用程序时遇到以下问题（编译过程没有问题），但是我的应用程序立即关闭。

小编典典从NoClassDefFoundError的javadoc：
如果Java虚拟机或ClassLoader实例尝试加载类的定义（作为常规方法调用的一部分或使用新表达式创建新实例的一部分）而抛出，则找不到该类的定义。
Java使用动态链接，这意味着在首次使用符号（类名，…）时就进行了链接。正如Mohit已经指出的那样，您似乎缺少了JXMPP库，它是Smack的（传递）依赖项。我假设您确实只是通过将Smack放入libs/文件夹中而将其添加到项目中。不建议使用这种方法，因为您很容易错过Smack的传统依赖，就像您遇到的那样。而是使用能够解决诸如Maven或Gradle之类的依赖关系的构建系统。也可以看看：

小编典典我遇到了这个问题，只是找到了解决方法-
答案是RTFM！以下是说明：https
:
//developer.android.com/tools/building/multidex.html
Multidexing是一项新功能，因此需要支持库才能与棒棒糖之前的设备兼容。您需要将以下内容添加到gradle文件依赖项中：
compile ''com.android.support:multidex:1.0.0''同时在gradle文件中启用multidex输出：
android { compileSdkVersion 21 buildToolsVersion "21.1.0" defaultConfig { ... minSdkVersion 14 targetSdkVersion 21 ... // Enabling multidex support. multiDexEnabled true }}然后将multidex支持应用程序添加到清单中：
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.android.multidex.myapplication"> <application ... android:name="android.support.multidex.MultiDexApplication"> ... </application></manifest>注意：
如果您的应用程序已经扩展了Application类，则可以重写attachBaseContext（）方法并调用MultiDex.install（this）以启用multidex。有关更多信息，请参见MultiDexApplication参考文档。
@Overrideprotected void attachBaseContext(Context context) { super.attachBaseContext(context); MultiDex.install(this);}同样，请参阅上面的说明以获取更多信息…

解决方法:
这是Gradle bulid配置问题我也有同样的问题
在Gradle你的使用
compile 'com.google.android.gms:play-services:8.4.0'
Enire Google Playservice Lib可以更改您的项目中使用的lib
例
com.google.android.gms:play-services-gcm:8.4.0
com.google.android.gms:play-services-maps:8.4.0
com.google.android.gms:play-services-auth:8.4.0
请参阅此URl https://developers.google.com/android/guides/setup#add_google_play_services_to_your_project
android – 错误“java.lang.NoClassDefFoundError：com.google.repacked.apache.commons.io.FileUtils”
Android应用在build.gradle中包含以下内容：
dependencies {
...
compile 'commons-io:commons-io:2.4'
}
构建和安装应用程序没有问题.但是以下代码：
FileUtils.writeStringToFile(fText, "Test");
导致以下异常：
java.lang.NoClassDefFoundError: com.google.repacked.apache.commons.io.FileUtils
任何人都可以提供一个如何解决这个问题的提示吗？
[编辑：]
我刚刚意识到应用程序仍然可以在build.gradle中没有以下内容的情况下构建：
dependencies {
...
compile 'commons-io:commons-io:2.4'
}
FileUtils如下：
任何人都可以告诉com.google.repacked是什么以及如何摆脱它？
解决方法:
快速猜测,但似乎你没有使用公共库中的FileUtils.仔细检查import语句以查看从哪里导入FileUtils.
确保您要导入org.apache … FileUtils类,而不是com.google …包中的内容.
