Zxing改变动作意图

发布于 2024-12-06 11:58:59 字数 163 浏览 0 评论 0原文

我将 Zxing 库添加到我的 Android 应用程序中，但出现了问题。当您已经安装了条形码扫描仪时，它会向您显示带有弹出窗口。我不希望这种情况发生并改变了操作意图。这是有效的，但是当我第一次打开我的应用程序并选择条形码扫描仪崩溃了。当我第二次打开它时，一切正常。

有人可以帮我吗？

我已经在邮件列表上回答过这个问题几次了。正如我所说，您需要注意 ActivityNotFoundException。

当你启动一个没有应用程序的意图时，Android 会抛出这个错误，这就是这里发生的情况。您需要自己处理这个问题，方法是捕获异常，也许还可以将用户发送到市场进行下载。

这正是 zxing 中 android-integration 中的代码所做的，这就是为什么我也已经告诉你看一下它。

I've already answered this a few times on the mailing list. As I said, you need to pay attention to ActivityNotFoundException.

Android throws this when you start an intent for which there is no app, and that's what's happening here. You need to handle this yourself by catching the exception and, maybe, sending the user to Market to download.

This is exactly what the code in android-integration in zxing does, which is why I also already told you to look at that.
