Slog.d(TAG,"res = " + (res != null ? res.activityInfo.packageName : null));

homeIntent.addCategory(Intent.CATEGORY_LAUNCHER_APP);
List<ResolveInfo> resList = mContext.getPackageManager().queryIntentActivities(homeIntent,0);//正常只有一个
if(resList != null && resList.size() != 0){
    int size = resList.size();
    for (int index = 0;index <size;index ++ ){
        Slog.d(TAG,"index " + index + ": " + resList.get(index).getComponentInfo().packageName);
