我见过的，有在谷歌应用程序的地方，安装完毕后，应用程序将没有图标显示尚未将在后台运行的服务的一些GPS应用。

I've seen that there are some GPS application on Google apps where, after installation, the application will have no icon display yet will run services in the background.

我将如何实现这一目标？

How would I achieve this?

推荐答案

有关从启动删除应用程序只是没有把这些线，主要活动在的Andr​​oidManifest.xml

For removing Application from Launcher just do not put these lines with main Activity in AndroidManifest.xml

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

如果你想以编程方式删除它，然后使用PackageManager.setComponentEnabledSetting为从启动删除它：

  ComponentName componentToDisable =
  new ComponentName("com.xxx.apptodisable",
  "com.xxx.apptodisable.LauncherActivity");

  getPackageManager().setComponentEnabledSetting(
  componentToDisable,
  PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
  PackageManager.DONT_KILL_APP);
