Question

所以，我的应用程序的所有内容都工作得很好，直到有一天我尝试使用我的Lollipop 5.1手机进行测试，并在使用改造和 OkHttp 时崩溃库。

UncaughtException: java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/gson/Gson;

错误日志将我带到我的Application类，初始化Gson对象（Gson类完全在那里）。

public static Gson getGson() { return gson; }

private void initGson() {
    gson = new Gson();
}

很多答案都建议我使用Multidex。我已经尝试过启用multidex，但没有区别：

defaultConfig {
    applicationId yourApplicationId
    minSdkVersion 16
    targetSdkVersion 22
    multiDexEnabled true
    versionCode 74
    versionName '3.0.1'
}

在Application类中，在onCreate方法中：

MultiDex.install(getAppContext());

该应用程序仅在Android 5.0和5.1上崩溃，它可以在 Kitkat ， Marshmallow 和 Nougat 上正常运行。

编辑我将包含完整的build.gradle文件：

apply plugin: 'com.android.application'
apply plugin: 'realm-android'
apply plugin: 'com.jakewharton.butterknife'

我通过仅导入所需的Google服务库而不是整个软件包来解决此问题，所以不要这样做：

selectAll () { this.notify.emit(this.names); }

我分别导入每个库。显然，它同时加载了太多的库，这引发了一些奇怪的问题。

Gson上的NoClassDefFoundError不仅仅适用于Lollipop
