为什么“开放"?在 android 设备上安装 apk 后按钮被禁用? [英] why "Open" button after installing apk on android device is disabled?

问题描述

我有两个项目，我想将它们组合在一起.当我分别在 设备 上安装它们时，打开"按钮(在已表示的页面中)成功安装后)启用.但是当我组合它们时，打开"按钮将被禁用，虽然安装过程将成功完成.我猜这个错误是因为ma​​nifest文件，但我是不确定.谢谢您的时间.

I have two projects and I want to combine them together.When I install each of them separately on device ,"Open" button (in page that has been represented after successful installation) is enabled.But when I combine them,"Open" button will be disabled, although installation process will be completed successful.I guess that this error is because of manifest file,but I am not sure.Thanks you in regards your time.

推荐答案

如果没有看到你的清单，我不能肯定地说，但我的猜测是，当你将两个项目结合起来时，你最终得到了两个活动，每个活动都包括:

I can't say for certain without seeing your manifest, but my guess is that when you combined the two projects, you ended up with two activities that each included:

<intent-filter>
    <action android:name="android.intent.action.MAIN" />`
    <category android:name="android.intent.category.LAUNCHER" />`
</intent-filter>

如果您确保只在要使用打开"按钮打开的活动中说，我想它会起作用.

If you make sure to only say that in the activity you want to open with the "Open" button, I imagine it will work.

要清楚，像这样有多个入口点是可以的，但它似乎仍然可以解释打开"按钮被禁用，因为它应该做什么是不明确的.

To be clear, it's fine to have multiple entry points like this, but it still seems likely to explain that "Open" button being disabled, since it's ambiguous what it should do.
