推荐答案

您可以通过这块code的检查当前的默认启动：

You can check current default launcher by this piece of code:

    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_HOME);
    ResolveInfo resolveInfo = getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY);
    String currentHomePackage = resolveInfo.activityInfo.packageName;

在这个答案显示：How我可以在Android 2.3及以上得到当前发射的包名？

所以，简单地检查是否 currentHomePackage 等于应用的程序包和采取相应的行动。

So simply check if currentHomePackage equals your App's Package and act accordingly.

如果用户设置另一个应用程序为默认启动的对话框选择一个默认的启动只会再次出现，如果他delets的发射器默认设置或删除/安装一个应用程序，可以为默认启动程序行事。

If the user sets another App as Default Launcher the Dialog to choose a Default Launcher would only appear again if he delets the Launchers Defaults or removes/installs an App which can act as default launcher.
