Android获取非Play商店应用的列表 [英] Android get list of non Play Store apps

问题描述

作为安全措施，我希望获得未从Play商店安装的应用程序列表。有没有办法做到这一点？
$ b

packageManager 包含一个方法 getInstalledApplications ，但我不知道不知道要添加哪个标记来获取列表。任何帮助将不胜感激。

编辑：这是v4_adi答案的代码示例。

  public static List< String> getAppsFromUnknownSources（上下文上下文）
 {
 List< String> apps = new ArrayList<>（）; 
 PackageManager packageManager = context.getPackageManager（）; 
列表< PackageInfo> packList = packageManager.getInstalledPackages（0）; 
 for（int i = 0; i< packList.size（）; i ++）
 {
 PackageInfo packInfo = packList.get（i）; 
 if（packageManager.getInstallerPackageName（packInfo.packageName）== null）
 {
 apps.add（packInfo.packageName）; 
} 
} 
 
返回应用; 
} 
  

这是一个很好的开始，但是这也会预先安装很多Android和三星应用程序。无论如何将它们从列表中删除？我只想要用户安装来自未知来源的应用程序。

解决方案

原本我认为这足以检索那些不是通过Google Play商店安装。后来我发现我也需要过滤掉预先安装的系统应用程序。
我在另一篇文章中发现了难题的最后部分：获取Non系统应用程序

  public static List< String> getAppsFromUnknownSources（上下文上下文）
 {
 List< String> apps = new ArrayList<>（）; 
 PackageManager packageManager = context.getPackageManager（）; 
列表< PackageInfo> packList = packageManager.getInstalledPackages（0）; 
 for（int i = 0; i< packList.size（）; i ++）
 {
 PackageInfo packInfo = packList.get（i）; 
 boolean hasEmptyInstallerPackageName = packageManager $ b $ .getInstallerPackageName（packageInfo.packageName）== null; 
 boolean isUserInstalledApp =（packageInfo.applicationInfo.flags& ApplicationInfo.FLAG_SYSTEM）== 0; 
 
 if（hasEmptyInstallerPackageName&& isUserInstalledApp）
 {
 apps.add（packInfo.packageName）; 
} 
} 
 
返回应用; 
} 
  

As a safety measure I would like to get the list of apps that aren't installed from the Play Store. Is there a way to do this?

The packageManager contains a method getInstalledApplications but I don't know which flags to add to get the list. Any help would be appreciated.

Edit: Here is an code example of v4_adi's answer.

public static List<String> getAppsFromUnknownSources(Context context)
{
  List<String> apps = new ArrayList<>();
  PackageManager packageManager = context.getPackageManager();
  List<PackageInfo> packList = packageManager.getInstalledPackages(0);
  for (int i = 0; i < packList.size(); i++)
  {
     PackageInfo packInfo = packList.get(i);
     if (packageManager.getInstallerPackageName(packInfo.packageName) == null)
     {
        apps.add(packInfo.packageName);
     }
  }

  return apps;
}

This is a good start, however this also returns a lot off pre-installed Android and Samsung apps. Is there anyway to remove them from the list? I only want user installed apps from unknown sources.

解决方案

Originally I thought it would be enough to retrieve the apps that weren't installed via the Google Play Store. Later I found that I also needed to filter out the pre-installed system applications. I found the last part of the puzzle in another post: Get list of Non System Applications

public static List<String> getAppsFromUnknownSources(Context context)
{
  List<String> apps = new ArrayList<>();
  PackageManager packageManager = context.getPackageManager();
  List<PackageInfo> packList = packageManager.getInstalledPackages(0);
  for (int i = 0; i < packList.size(); i++)
  {
     PackageInfo packInfo = packList.get(i);
     boolean hasEmptyInstallerPackageName = packageManager
           .getInstallerPackageName(packageInfo.packageName) == null;
     boolean isUserInstalledApp = (packageInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 0;

     if (hasEmptyInstallerPackageName && isUserInstalledApp)
     {
        apps.add(packInfo.packageName);
     }
  }

  return apps;
}
