android - 如何解决java.lang.NoClassDefFoundError : okio. Okio？

Question

我有一个运行良好的应用程序，但有时当我向我的程序添加一些类和代码时，我的应用程序崩溃了。在我的 logcat 错误是这样的:

 8871-8929/com.example.first E/AndroidRuntime﹕ FATAL EXCEPTION: pool-4-thread-1
java.lang.NoClassDefFoundError: okio.Okio
    at com.squareup.okhttp.internal.http.HttpConnection.<init>    (HttpConnection.java:90)
    at com.squareup.okhttp.Connection.connectSocket(Connection.java:208)
    at com.squareup.okhttp.Connection.connect(Connection.java:172)

    at com.squareup.okhttp.internal.huc.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:233)

也许您正在跨越 65K 方法限制，并设置了 multiDexEnabled = true，但还没有正确完成多索引设置？

如果你还没有，需要添加:

dependencies {
  compile 'com.android.support:multidex:1.0.1'
}

和

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

类扩展应用
