为什么＆QUOT;开放＆QUOT;安装Android设备上的apk后，按钮被禁用？
我有两个项目，我想将它们合并together.When我在设备上，分别安装他们每个人的打开按钮（在页面已被重新安装成功后psented）$ p $是enabled.But当我将它们合并，打开按钮将被禁用，但安装过程中会完成successful.I猜测，这个错误是因为清单文件，但我不sure.Thanks你问候你的时间。结果
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.
我不能肯定地说，没有看到你的表现，但我的猜测是，当你结合这两个项目中，结束了两个活动，每个包括
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>
如果您务必只能说你想用打开按钮，打开活动，我想它会工作。
If you make sure to only say that in the activity you want to open with the "Open" button, I imagine it will work.
编辑：需要明确的是，它的罚款，有多个入口这样，但它似乎仍然有可能解释说，打开按钮被禁用，因为它是含糊不清是什么应该做的。
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.
