对于OkHttpClient，NoClassDefFoundError [英] NoClassDefFoundError for OkHttpClient

问题描述

请注意，我也使用okhttp： / p>

  compile'c​​om.squareup.okhttp：okhttp：2.5.0'
  pre> 
 
 
和错误日志是：

解决方案
 你正在得到 
  java.lang.NoClassDefFoundError：com.squareup.okhttp.internal.Util 
 at com。 squareup.okhttp.OkHttpClient。< clinit>（OkHttpClient.java:57）
 at com.venkat.project.http.MyHTTPThread.run（MyHTTPThread.java:127）
 at com.venkat.project .http.MyHTTPThread.run（MyHTTPThread.java:61）
  
 
 
 
 OkHttpClient的NoClassDefFoundError 
 
 
 
  public class NoClassDefFoundError extends LinkageError 
  
 
 
 
 
 
如果Java虚拟机或ClassLoader实例尝试在类的定义中加载
（作为正常方法调用的一部分或
作为创建的一部分）使用新的exp的新实例可以找到该类的
定义。
 
 
从  NoClassDefFoundError   
 
 
 
您应该使用
  compile'c​​om.facebook.android:facebook-android-sdk:4.10.0' 
  
之后，您可以通过非零退出值2得到此错误    
 
 
 
 然后 
 code> defaultConfig {
 ... 
 minSdkVersion 14 //低于14不支持multidex 
 targetSdkVersion //您的
 
 //启用multidex支持。 
 multiDexEnabled true 
} 
 
依赖关系{
 compile'c​​om.android.support:multidex:1.0.0'
} 
  
 
 
 
 
 
 
添加 multiDexEnabled true   
 
 
 
 
 code> compile'c​​om.android.support:multidex:1.0.0' //或1.0.1 
 
 
 
 
 
 
 
 
 OkHttp在网络麻烦时坚持不懈：它将静默地从
恢复常见的连接问题。如果您的服务有多个
 IP地址，如果第一个
连接失败，OkHttp将尝试替代地址。这对于IPv4 + IPv6和冗余数据中心的
服务是必需的。
 
 
您可以调用最新版本
 
 
 
  compile'c​​om.squareup.okhttp3：okhttp：3.2.0'
  
 最后 
  compile'c​​om .squareup.okhttp3：okhttp：3.0.1'
或//编译'com.squareup.okhttp：okhttp：2.5.0'
 compile'c​​om.facebook.android:facebook-android-sdk： 4.10.0'
  
 然后 
 
 
 
  清洁和重新构建&同步 您的项目。希望这有帮助。
 
After adding the facebook dependency in gradle I'm getting this runtime error:
     compile 'com.facebook.android:facebook-android-sdk:4.6.0'
Please notice that I'm also using okhttp: 
    compile 'com.squareup.okhttp:okhttp:2.5.0'
and error log is:
 E/AndroidRuntime: FATAL EXCEPTION: Thread-109754

解决方案
You are getting
       java.lang.NoClassDefFoundError: com.squareup.okhttp.internal.Util
        at com.squareup.okhttp.OkHttpClient.<clinit>(OkHttpClient.java:57)
        at com.venkat.project.http.MyHTTPThread.run(MyHTTPThread.java:127)
        at com.venkat.project.http.MyHTTPThread.run(MyHTTPThread.java:61)


NoClassDefFoundError for OkHttpClient

public class NoClassDefFoundError extends LinkageError



  
Thrown if the Java Virtual Machine or a ClassLoader instance tries to
  load in the definition of a class (as part of a normal method call or
  as part of creating a new instance using the new expression) and no
  definition of the class could be found.
Quote from NoClassDefFoundError

You should use 
compile 'com.facebook.android:facebook-android-sdk:4.10.0'
After that you can get this error finished with non-zero exit value 2

Then 
defaultConfig {
    ...
    minSdkVersion 14 //lower than 14 doesn't support multidex
    targetSdkVersion //Yours

    // Enabling multidex support.
    multiDexEnabled true
}

dependencies {
 compile 'com.android.support:multidex:1.0.0'
}



Add  multiDexEnabled true
Call  compile 'com.android.support:multidex:1.0.0' // or 1.0.1



  
OkHttp perseveres when the network is troublesome: it will silently
  recover from common connection problems. If your service has multiple
  IP addresses OkHttp will attempt alternate addresses if the first
  connect fails. This is necessary for IPv4+IPv6 and for services hosted
  in redundant data centers.
You can call latest version 
compile 'com.squareup.okhttp3:okhttp:3.2.0'
Finally
compile 'com.squareup.okhttp3:okhttp:3.0.1'
or // compile 'com.squareup.okhttp:okhttp:2.5.0'
compile 'com.facebook.android:facebook-android-sdk:4.10.0'
Then

Clean and Re-Build & Sync Your Project . Hope this helps .
