Android Studio:应用程序图标未出现在主屏幕或应用程序列表中 [英] Android Studio: App icon doesn't appear in the home screen or app list

问题描述

我自己开发的应用存在严重问题.

I have a serious problem with my self developed app.

长话:

我已经创建了一个应用程序并在我的台式电脑上开发了它.因为我需要向我的客户展示它，我决定在我的笔记本上安装 android studio 并在那里试用该应用程序.我在我的笔记本上导入了项目并启动了 Android Studio，我运行了该项目，该应用程序像往常一样在我的智能手机上启动并运行，但是......当我回到主屏幕时，图标丢失了(在我的桌面上时)pc 版本已显示)，它甚至不在应用程序列表中，但如果我继续设置"-->管理应用程序"，它会显示在那里，我可以卸载或停止它，但因为我没有一个图标 如果我不使用 Android Studio 重新运行应用程序，我将无法再次启动它.我回到我的台式电脑并尝试从那里重新运行应用程序，但没有任何改变，图标仍然丢失.

I have created an app and developed it on my desktop pc. Because I need to show it to my customer, I decided to install android studio on my Notebook and try the app there. I imported the project on my Notebook and started Android Studio, I ran the project, the app started and worked like always on my smartphone but......when I went back to the homescreen the Icon was missing (while on my desktop pc version was shown) and it wasn't even in the app list, but if I go on "Settings" --> "Manage applications", it's shown there, I can unistall or stop it, but because I don't have an icon I can't start it again if I don't rerun the app with Android Studio. I went back to my desktop pc and tried to rerun the app from there, but nothing changed the icon is still missing.

Short Story:在我的笔记本上使用 android studio 在我的手机上重新安装我的应用程序后，主屏幕和应用程序列表中缺少应用程序图标，但我可以在设置"->管理应用程序"中看到它.如果我回到我开发应用程序的原始电脑并尝试重新运行它，结果是一样的...图标丢失.

Short Story: After reinstalling my app on my phone with android studio from my notebook, the app icon is missing from the home screen and application list, but I can see it in "Settings" --> "Manage applications". If I go back to my original pc where I developed the app and try to rerun it, the result is the same...icon missing.

我在 Stackoverflow 上阅读了所有与我的问题类似的帖子，但没有任何帮助我解决它.我希望有人可以帮助我.

I read all the post that are similar to my problem on Stackoverflow, but nothing helped me to resolve it. I hope that someone can help me about it.

I posted the AndroidManifest.xml if needed but I can't post all the code because of privacy/copyright, sorry. I tried to write in the most correct english I could, I apologize in advance if my writing is horrible.

推荐答案

发生这种情况是因为您将所有内容都传递到了一个意图过滤器中.尝试在每个用例中将它们分开，或者至少将启动器和主过滤器分开.

It is happening because you passed everything into one intent filter. Try to separate them per use case or at least separate Launcher and Main filter.

像这样:

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

        <action android:name="android.intent.action.SEND" />
        <action android:name="android.intent.action.SENDTO" />

        <data android:scheme="sms" />
        <data android:scheme="smsto" />
        <data android:scheme="mms" />
        <data android:scheme="mmsto" />
</intent-filter>
