Answer 1

You can use this code to get the list of applications:

PackageManager pm = this.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN, null);

String activityName = rInfo.activityInfo.name;
List list = pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);

for (ResolveInfo rInfo : list) {
    pkg = rInfo.activityInfo.applicationInfo.packageName;
    if (pm.getLaunchIntentForPackage(pkg) == null) {
      continue;
    }
    String label = rInfo.activityInfo.applicationInfo.loadLabel(pm).toString();
    arrayList.add(new AppEntry(label, activityName, pkg, null));
}
