NoClassDefFoundError：org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration only API 19

Question

一週前，我開始使用Smack API（4.1.8版本）將Chat System應用到我的應用程序。它也適用於Lolipop裝置和棉花糖。但在奇巧（API 19）我得到異常的NoClassDefFoundError logcat的：

Process: mobi, PID: 23510 
    java.lang.NoClassDefFoundError: org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration 
    at mobi.networking.ChatXMPPConnection.connect(ChatXMPPConnection.java:76) 
    at mobi.networking.ChatXMPPService.initConnection(ChatXMPPService.java:80) 
    at mobi.networking.ChatXMPPService.access$100(ChatXMPPService.java:36) 
    at mobi.networking.ChatXMPPService$1.run(ChatXMPPService.java:112) 
    at java.lang.Thread.run(Thread.java:841) 

那麼，什麼是它的線76（第一線）：

XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder(); 
     configBuilder.setUsernameAndPassword(mUsername, mPassword); 
     configBuilder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled); 
     configBuilder.setResource("Android"); 
     configBuilder.setServiceName(DOMAIN); 
     configBuilder.setHost(HOST); 
     configBuilder.setPort(PORT); 

我的集結gradle這個：

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

android { 
    compileSdkVersion 24 
    buildToolsVersion "24.0.3" 
    dataBinding 
      { 
       enabled = true 
      } 

    defaultConfig { 
     applicationId "mobi" 
     minSdkVersion 19 
     targetSdkVersion 24 
     versionCode 1 
     versionName "1.0" 
     multiDexEnabled true 
    } 
    buildTypes { 
     release {

另外，我的libs文件夾是空的。我不使用的jar-文件​​

請幫助我解開已進行修正

我也面臨着同樣的問題兩天。 嘗試添加以下的依賴：

compile 'com.android.support:multidex:1.0.1'

，並在您的應用程序類中添加這，

@Override 
    protected void attachBaseContext(Context base) 
    { 
      super.attachBaseContext(base); 
      MultiDex.install(BaseApplication.this); 
    }
