Question

我只是希望我的应用程序可供用户使用Share Via Intent Chooser从图库共享照片。此外，我想在通过屏幕选择我的应用程序之后执行我的应用程序的基本操作，如watsapp。我不知道该怎么做。我在互联网上搜索，但我没有得到任何满意的解决方案。感染我试过this

但遗憾的是在清单中使用此代码我的应用程序已从设备的主屏幕应用程序列表中消失。

查看我的清单文件：

Answer 1

您的应用程序“消失了”，因为您在SplashActivity部分评论了这些行：

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

至于共享提供者，你被困在哪个部分？
