求助：ios和安卓app 能获取到当前设备上所有的应用列表信息吗

// 获取用户已装应用列表  
plus.android.importClass("java.util.ArrayList");  
plus.android.importClass("android.content.pm.PackageInfo");  
plus.android.importClass("android.content.pm.PackageManager");  
const ApplicationInfo = plus.android.importClass("android.content.pm.ApplicationInfo");  
const MainActivity = plus.android.runtimeMainActivity();  
const PackageManager = MainActivity.getPackageManager();  
const installedPackages = plus.android.invoke(PackageManager, "getInstalledPackages", 0);  
if (installedPackages != null) {  
  const apkList = [];  
  for (let i = 0; i < installedPackages.size(); i++) {  
    const pkginfo = installedPackages.get(i);  
    const issysapk =  
      (pkginfo.plusGetAttribute("applicationInfo").plusGetAttribute("flags") &  
        ApplicationInfo.FLAG_SYSTEM) !=  
      0  
        ? true  
        : false;  
    if (issysapk == false) {  
      const apkinfo = {  
        appName: pkginfo.plusGetAttribute("applicationInfo").loadLabel(PackageManager).toString(),  
        packageName: pkginfo.plusGetAttribute("packageName"),  
        versionName: pkginfo.plusGetAttribute("versionName"),  
        versionCode: pkginfo.plusGetAttribute("versionCode"),  
      };  
      apkList.push(apkinfo);  
    }  
  }  
  console.log(JSON.stringify(apkList));  
}  

在网上找了一篇文章，是原生ios的代码，需要怎么转成uni-app的代码？
