我正在开发一个Android应用程序，其最小sdk为7，目标为16.该应用程序实现了一个广播接收器，它接收新的传入短信并将邮件正文和发件人号码邮寄给admin.til现在应用程序运行正常但是有要求在安装后保持应用程序隐藏。所以我何时从清单中删除了这些行
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
应用程序确实被隐藏了但是没有发送邮件。所以我认为当我隐藏应用程序不知道确切的原因时，广播接收器没有被调用...下面是我的代码......从最近两天开始。非常感谢任何帮助...
我的清单文件
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

系统或任何其他应用程序都不会启动应用程序的任何部分，除非用户自Android 3.1以来手动启动该应用程序的主要活动。
因此，您必须为您的应用提供启动器活动，并让用户在您的BroadcastReceiver在Android 3.1及更高版本上运行之前打开它。

Android具有基本的安全功能，在该应用程序的活动运行之前，不会启用应用程序的后台服务，接收器等。
