你可以用这个:

PackageManager pm = getApplicationContext().getPackageManager();
                List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0);
                for (final ResolveInfo app : activityList) 
                {
                   if ((app.activityInfo.name).contains("facebook")) 
                   {
                     // facebook  
                   }

                   if ((app.activityInfo.name).contains("android.gm")) 
                   {
                     // gmail  
                   }

                   if ((app.activityInfo.name).contains("mms")) 
                   {
                     // android messaging app
                   }

                   if ((app.activityInfo.name).contains("com.android.bluetooth")) 
                   {
                     // android bluetooth  
                   }
                }

获取所有应用程序:

    PackageManager pm = getContext().getPackageManager();
    List<ApplicationInfo> apps = pm.getInstalledApplications(0);

检查是否安装了应用程序，然后打开:

if((app.flags & (ApplicationInfo.FLAG_UPDATED_SYSTEM_APP | ApplicationInfo.FLAG_SYSTEM)) > 0) {
                String app_package = app.packageName;
Intent launchIntent = context.getPackageManager().getLaunchIntentForPackage(app_package);
context.startActivity(launchIntent);

获取已安装的非系统应用程序列表

public static void installedApps()
{
    List<PackageInfo> packList = getPackageManager().getInstalledPackages(0);
    for (int i=0; i < packList.size(); i++)
    {
        PackageInfo packInfo = packList.get(i);
        if (  (packInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 0)
        {
            String appName = packInfo.applicationInfo.loadLabel(getPackageManager()).toString();
            Log.e("App № " + Integer.toString(i), appName);
        }
    }
}

过滤基于系统的应用程序:

private boolean isSystemPackage(ResolveInfo ri) {
    return (ri.activityInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0;
}

我需要过滤掉用户并不真正使用的系统应用程序(例如。“com.qualcomm。服务”，“更新服务”等)。最后，我添加了另一个条件来过滤应用程序列表。我只是检查了应用程序是否有“启动意图”。

因此，结果代码看起来像……

PackageManager pm = getPackageManager();
        List<ApplicationInfo> apps = pm.getInstalledApplications(PackageManager.GET_GIDS);

        for (ApplicationInfo app : apps) {
            if(pm.getLaunchIntentForPackage(app.packageName) != null) {
                // apps with launcher intent
                if((app.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) {
                    // updated system apps

                } else if ((app.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
                    // system apps

                } else {
                    // user installed apps

                }
                appsList.add(app);
            }

        }

另一种过滤系统应用程序的方法(适用于king9981的例子):

/**
 * Return whether the given PackageInfo represents a system package or not.
 * User-installed packages (Market or otherwise) should not be denoted as
 * system packages.
 * 
 * @param pkgInfo
 * @return
 */
private boolean isSystemPackage(PackageInfo pkgInfo) {
    return ((pkgInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0);
}
