如何阅读iOS上安装的所有应用程序的列表

Question

Twitter is all over the news about wanting to collect a list of all apps installed on users iOS and Android.

Is there any recent API I'm no aware off that allows them to do that? or are they scanning app url schemes registered?

Answer 1

If you want to get the list of installed apps in android you can use this:

/**
 * Returns a list of installed apps
 */
public static ArrayList<PackageInformation> getInstalledApps(
        Context contxt, boolean getSysPackages) {
    ArrayList<PackageInformation> pacakgeInformationList = new ArrayList<PackageInformation>();
    List<PackageInfo> packs = contxt.getPackageManager()
            .getInstalledPackages(0);

    for (int i = 0; i < packs.size(); i++) {
        PackageInfo packageInfo = packs.get(i);
        if ((!getSysPackages)) {
            continue;
        }
        PackageInformation newInfo = new PackageInformation();
        newInfo.setAppName(packageInfo.applicationInfo.loadLabel(
                contxt.getPackageManager()).toString());
        newInfo.setPacakgeName(packageInfo.packageName);
        newInfo.setVersionName(packageInfo.versionName);
        newInfo.setVersionCode(packageInfo.versionCode);
        newInfo.setIcon(packageInfo.applicationInfo.loadIcon(contxt
                .getPackageManager()));
        pacakgeInformationList.add(newInfo);
    }
    return pacakgeInformationList;
}

and after that you just need permission to access to the internet and then easily send what information you want to what server you want.

So unfotunatley YES, it's possible to do that in android.

And for ios please see this post: Get list of all installed apps

They said without jailbroken iPhones you can not do this.

Piece of code will bring you all the list of activities/applications installed on Android :

final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List pkgAppsList = context.getPackageManager().queryIntentActivities( mainIntent, 0);
