Question

好的，这是一个有趣的：我正在使用Android Studio 1.1.0，我有一个Android应用程序和一个相关的Android Wear应用程序，我正在尝试在智能手表设备上进行测试。我将我在Android应用程序中使用的类文件放入Android库模块，然后将其作为依赖项添加到我的Android Wear应用程序中。该应用程序构建并部署到智能手表上，但当它运行时，我得到以下异常和堆栈跟踪。任何建议，将不胜感激。谢谢！

Answer 1

我在你的logcat跟踪中看到了这个java.lang.ClassNotFoundException: android.support.v4.util.ArrayMap。我想也许v4和v7的版本会导致此错误。您的v4和v7支持库是最新的吗？而BTW，ArrayMap仅可用于Android API 21+

Answer 2

在我的情况下，我通过删除 android-support-v4.jar 解决了这个问题，因为它已经过时并且实际上并没有 ArrayMap.class 而我放了一个来自我的lib文件夹中的 \ extras \ android \ support \ v4 然后将其添加到Java构建路径，它最终工作。希望它有所帮助：）

Answer 3

您可以找到此错误的解决方案here。

错误非常明显（基本上缺少ArrayMap）：

java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v4/util/ArrayMap;

这是因为支持库版本旧，而另一个库（可能是Google Play服务）在其上找不到ArrayMap。

解决方案是将支持库升级到包含ArrayMap的新版本。这就是我所做的并且有效。

此外，根据linked solution您还应该：

确保您的compileSdkVersion与主要版本号匹配依赖

WearableListView ClassNotFoundException支持v4 ArrayMap
