Question

我正试图让BarcodeEye在我自己的项目中工作。当我在eclipse中导入项目并尝试运行它时，它工作得很好。

然后我尝试了以下3种方式在android studio中获取它。

首先，我将现有项目所需的所有文件复制到我自己的项目中。在设置了所有te正确的导入和包名后，当我尝试构建它时会出现4个错误（将在下面发布错误）
我直接在android工作室打开了eclipse项目并试图构建它。我有4个错误（见下文）
我将eclipse项目导出到gradle，然后在android studio中打开它。我又犯了4个错误。

有没有人知道这里出了什么问题？

好好仔细看看AsyncTasks他们自己后，我发现了错误的来源。

显然，在将项目转换为android studio时，它并没有采用asyncTask

的值

看起来像这样

AsyncTask<?, ?, ?> someTask;

然后我接着改变了所有的AsyncTask来保存适当的功能。

因此，如果其他人遇到此问题，请检查您的AsyncTask标识符，这是导致问题的原因

项目从eclipse运行但是当导出到gradle异步抛出错误时
