【中文标题】Fabric/Crashlytics NoClassDefFoundError 仅在某些设备上【英文标题】：Fabric/Crashlytics NoClassDefFoundError only on certain devices 【发布时间】：2015-08-19 13:37:13 【问题描述】：我在 Google Play 中看到与 Fabric/Crashlytics 相关的崩溃。这发生在我从普通 Crashlytics 更新到新的 Fabric Crashlytics 之后。我只能在我的一台设备（Galaxy S2）上重现它。我拥有的所有其他设备（Nexus 5 和 S4）都没有崩溃。这是堆栈跟踪：

【问题讨论】：
您使用哪个版本的 crashlytics？另外，请发布您的 build.gradle 文件的内容。 更新了 build.gradle 的内容。我相信我正在使用 Crashlytics 2.4.0。 【参考方案1】：我只是凭直觉想通了！最近升级到新的 Fabric 框架后不得不添加多 dex 支持，感觉可能是我没做对。所以在添加了这些额外的更改后，现在它不再崩溃了：
在我的 build.gradle 中，我添加了增量设置：
dexOptions
incremental true
javaMaxHeapSize "4g"
还有一个额外的依赖：
compile 'com.android.support:multidex:'
在我的应用程序类上，我正在扩展 MultiDexApplication：
public class TownsquareEvents extends android.support.multidex.MultiDexApplication
【讨论】：
我有同样的问题，我有除此之外的所有 multidex 代码：“incremental true”。该问题目前在某些设备上重现，我没有并且无法检查它们。那里是否需要“增量真实”参数？ 可能对某人有所帮助的其他信息：在我的应用程序类中，我保留了 MultiDex.install(this);在 attachBaseContext() 中，但它应该在 super() 调用之后的 onCreate() 中。这为我解决了这个问题。希望这会有所帮助 这行得通，但我收到了关于 DexOptions.incremental 在 2018 年底过时的警告，这并没有给我带来温暖的模糊感。【参考方案2】：请构建这个：编译'com.android.support:multidex:1.0.1'
并在您的应用程序类中添加此方法：
protected void attachBaseContext(Context base)
super.attachBaseContext(base);
MultiDex.install(this);
【讨论】：
【参考方案3】：如果您正确使用MultiDex，但仍然遇到此错误，可能是因为您使用的是Proguard，而MultiDex 不知道要保留哪些类。
因此，请务必将您的 MultiDex 保留文件与您的 Proguard .pro 文件“同步”。
示例：
buildTypes
// other stuff...
release
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
ext.enableCrashlytics = true
//
// IMPORTANT PART:
//
// tell your MultiDex to keep the classes you defined in your Proguard .pro file.
multiDexKeepProguard file('proguard-rules.pro')
通过这样做，您无需手动指定multidex.keep 文件！
有关multiDexKeepProguard here 和来自 Google 的 full developer docs 的更多信息。
【讨论】：
如果您同时使用 proguard 和 multidex，这是关键。 当你同时使用Proguard 和MultiDex 时肯定是答案，我希望我早点知道。【参考方案4】：
两年后的附加信息：问题似乎只出现在运行 Android
【讨论】：
【参考方案5】：首先检查是否添加了 Fabric SDK，如果出现此错误，请检查以下文件。

【讨论】：
【参考方案6】：我正在尝试通过将 Crashlytics 更新到 2.9.1 来修复此错误。根据https://docs.fabric.io/android/changelog.html#february-28-2018：
修复了当 Firebase Core 未明确包含为依赖项时导致 Firebase Crashlytics 无法启动的错误。
我的build.gradle 现在改为：
implementation('com.crashlytics.sdk.android:crashlytics:2.9.1@aar')
transitive = true;
编辑：没有帮助。在 Android 4.x 上，Crashlytics 崩溃。多么讽刺。
【讨论】：
以上是关于Fabric/Crashlytics NoClassDefFoundError 仅在某些设备上的主要内容，如果未能解决你的问题，请参考以下文章
