getPackageManager ().getInstalledPackages (PackageManager.GET_ACTIVITIES) returns null

Question

If I call

    PackageManager pm = getPackageManager () ;
    List pis = pm.getInstalledPackages (PackageManager.GET_PROVIDERS) ;

Answer 1

I came across the same issue and found out a better workaround:

public void listAllActivities() throws NameNotFoundException
{
    List packages = getPackageManager().getInstalledPackages(0);
    for(PackageInfo pack : packages)
    {
        ActivityInfo[] activityInfo = getPackageManager().getPackageInfo(pack.packageName, PackageManager.GET_ACTIVITIES).activities;
        Log.i("Pranay", pack.packageName + " has total " + ((activityInfo==null)?0:activityInfo.length) + " activities");
        if(activityInfo!=null)
        {
            for(int i=0; i

Notice that I need to query PackageManager twice. Once using getPackageManager().getInstalledPackages(...) and again using getPackageManager().getPackageInfo(...)

I hope it helps.
