Question

How do i use this method in a list to filter out the system package from a list?

I currently have this method up:

public static List<ApplicationInfo> getInstalledApplication(Context context) {
    PackageManager packageManager = context.getPackageManager();

    List<ApplicationInfo> apps = packageManager.getInstalledApplications(0);
    Collections.sort(apps, new ApplicationInfo.DisplayNameComparator(packageManager));
    return apps;
}

Method to filter out system package:

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

This will filter out system packages:

public static List<ApplicationInfo> getInstalledApplication(Context context) {
    PackageManager packageManager = context.getPackageManager();
    List<ApplicationInfo> apps = packageManager.getInstalledApplications(0);
    Collections.sort(apps, new ApplicationInfo.DisplayNameComparator(packageManager));
    Iterator<ApplicationInfo> it = apps.iterator();
    while (it.hasNext()) {
        ApplicationInfo ai = it.next();
        if ((ai.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
            it.remove();
        }
    }
    return apps;
}
