I think you should be able to use PackageManager.resolveActivity(), with the home intent.
我认为您应该能够使用PackageManager.resolveActivity()和 home 意图。
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;

in general, I agree to @JesusFrekeusing the PM resolveActivity
一般来说，我同意@JesusFreke使用 PM resolveActivity
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
ResolveInfo resolveInfo = getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY);
but to get the right package name, you should use
但要获得正确的包名，你应该使用
resolveInfo.loadLabel(packageManager).toString()
or
或者
resolveInfo.activityInfo.applicationInfo.loadLabel(packageManager).toString()
Hint: if there is no default set, this might become "Android System" or "open" as for the general System Intent Receiver
提示：如果没有默认设置，对于一般的系统意图接收器，这可能会变成“Android系统”或“打开”
Hint:
if you're looking for web browsers, you might use net.openid.appauth.browser.BrowserSelector#select()(0.7.1+) to implicit get the default browser even there is no one explicit set.
提示：如果您正在寻找网络浏览器，您可以使用net.openid.appauth.browser.BrowserSelector#select()( 0.7.1+) 来隐式获取默认浏览器，即使没有一个显式设置。
