android 为什么从 resolveActivity() 获得的 ResolveInfo 与从 queryIntentActivities() 获得的不同

Question

从 resolveActivity() 和 queryIntentActivities() 查看 ResolveInfo return 时，

为什么 ResolveInfo 与这两个意图相同的调用不同？

viewIntent 是 Intent(Intent.ACTION_VIEW, Uri.parse(deeplinkData)，而从 resolveActivity 编辑的 return 具有不相关的 packagename/name:

ResolveInfo info = pm.resolveActivity(viewIntent, PackageManager.MATCH_DEFAULT_ONLY);

        System.out.println("+++ 111 resolveActivity(), info.activityInfo.packageName:  "+info.activityInfo.packageName+",\ninfo.activityInfo.name: "+info.activityInfo.name);

它有日志：

+++ 111 resolveActivity(), info.activityInfo.packageName: android, 

info.activityInfo.name: com.android.internal.app.ResolverActivity

其中使用 queryIntentActivities

List<ResolveInfo> resInfo = pm.queryIntentActivities(viewIntent, 0);
if (!resInfo.isEmpty()){
            for (ResolveInfo info : resInfo) {

                System.out.println("+++ queryIntentActivities(), info.activityInfo.packageName: "+ (info.activityInfo.packageName));
                System.out.println("+++ +++ queryIntentActivities(), info.activityInfo.name: "+ (info.activityInfo.name));

                ......
            }
        }

有日志：

+++ queryIntentActivities(), info.activityInfo.packageName: com.client.android.debug
+++ +++ queryIntentActivities(), info.activityInfo.name: com.client.android.NewsActivity
+++ queryIntentActivities(), info.activityInfo.packageName: com.android.chrome
+++ +++ queryIntentActivities(), info.activityInfo.name: com.google.android.apps.chrome.IntentDispatcher

Answer 1

resolveActivity() returns 如果您调用 startActivity() 将启动的组件。那将是：

null 如果没有匹配项或者您没有在 Android 11+
activity 将从某个应用程序启动，如果只有一个匹配项或者用户选择默认值
选择器activity，如果有2+个匹配且没有默认值

在您的情况下，您将获得选择器 activity (com.android.internal.app.ResolverActivity)。

android why the ResolveInfo got from resolveActivity() is different than from queryIntentActivities()
