        super.onCreate(savedInstanceState);
        PackageManager pm = this.getPackageManager();

        Intent intent = new Intent(Intent.ACTION_MAIN, null);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);

        List list = pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
        for (ResolveInfo rInfo : list) {
            Log.w("Installed Applications", rInfo.activityInfo.applicationInfo.loadLabel(pm).toString());
        }
    }
}

Does anyone know how to solve these errors?

Try this:

public class Safety extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        PackageManager pm = this.getPackageManager();

        Intent intent = new Intent(Intent.ACTION_MAIN, null);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);

        ArrayList<ResolveInfo> list = (ArrayList<ResolveInfo>) pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
        for (ResolveInfo rInfo : list) {
            System.out.println("Installed Applications " + rInfo.activityInfo.applicationInfo.loadLabel(pm).toString());
        }

    }
}
