决定使用 Scandit SDK 在我的应用程序中获取条码扫描功能。不幸的是，由于我对 Android 开发和 Java 比较陌生，所以我遇到了一些我似乎无法解决的问题。Scandit 提供的演示没有给出任何错误（运行良好），但是当我尝试启动它时崩溃（从一个活动中按下一个按钮意味着启动它）。我已经尝试阅读 logcat 并在谷歌上搜索问题的解决方案，但我没有得到正确的解决方案。有谁知道我做错了什么？

Logcat 提供如下：

我也遇到了这个问题，我的解决方案是提取库文件并将它们作为文件放在 lib 文件夹中

该库基本上没有随它一起导出

编辑

所以我检查了我的项目，基本上我做了这些事情：

在libs文件夹中，我有一个名为的新文件夹armeabi，在里面我有libscanditsdk-android-3.3.1.so

然后在我的构建路径中，我还引用了他们提供的 jar 文件：

<classpathentry exported="true" kind="lib" path="C:/GIT/Android/FwayScannerProject/FwayScanner/libs/scanditsdk-barcodepicker-android-3.3.1.jar"/>
