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

我的自行开发的应用程序存在严重问题.

I have a serious problem with my self developed app.

长篇故事:

我创建了一个应用程序，并在台式机上进行了开发.因为我需要向客户展示它，所以我决定在我的笔记本电脑上安装android studio并在那里尝试该应用程序.我将项目导入我的笔记本电脑并启动了Android Studio，运行了该项目，该应用程序开始运行并像往常一样在智能手机上正常工作，但是……当我回到主屏幕时，图标丢失了(在我的台式机上显示了PC版本)，甚至没有出现在应用程序列表中，但是如果我在设置"->管理应用程序"上进行显示，则可以取消安装或停止它，但是因为我没有如果我不使用Android Studio重新运行该应用程序，则无法再次启动该图标.我回到桌面PC并尝试从那里重新运行该应用程序，但是图标仍然没有更改.

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.

短篇小说:从我的笔记本在装有android studio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该应用程序图标，但是我可以在设置"->管理应用程序"中看到它.如果我回到开发该应用程序的原始PC并尝试重新运行它，结果将是相同的...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.

我阅读了所有与我在Stackoverflow上的问题类似的帖子，但是没有任何帮助我解决它.我希望有人能帮助我.

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.

如果需要，我发布了AndroidManifest.xml，但是由于隐私/版权，我无法发布所有代码，对不起.我试图用最正确的英语来写，如果我的写得太糟了，我事先表示歉意.

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

之所以发生，是因为您将所有内容都传递给了一个意图过滤器.尝试根据用例将它们分开，或者至少将Launcher和Main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.
