我已经在Android Studio中在运行时尝试了.jar库的这些链接NoClassDefFoundError

还有这个链接

我的默认配置代码段如下：

 defaultConfig {
                applicationId "com.TCYonline.android.TCY_K12"
                minSdkVersion 14
                targetSdkVersion 23
                versionCode 1
                versionName "1.0"
                multiDexEnabled true

            }    

    dependencies {
            compile fileTree(dir: 'libs', include: ['*.jar'])
            compile 'com.android.support:appcompat-v7:23.1.0'
            compile 'com.squareup.okhttp:okhttp:2.5.0'
            compile 'com.android.support:multidex:1.0.0'
            compile 'com.squareup.mimecraft:mimecraft:1.1.1'
            compile 'com.android.support:recyclerview-v7:+'
            compile 'com.google.android.gms:play-services:8.3.0'
            compile 'com.android.support:design:23.1.0'
            compile 'com.google.code.gson:gson:2.3.1'
            compile 'com.facebook.android:facebook-android-sdk:4.0.0'
        }

Answer 1

将其添加到清单文件中的application标记中，这将解决问题

android:name="android.support.multidex.MultiDexApplication"
