Android 获取系统应用信息

我是仿照andorid launcher里面的方法，现抽取如下：

Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);final PackageManager packageManager = getPackageManager();List<ResolveInfo> apps = null;apps = packageManager.queryIntentActivities(mainIntent, 0);mNameList = new ArrayList<String>();mDrawableList = new ArrayList<Drawable>();mNameList.clear();mDrawableList.clear();if(apps != null && apps.size() > 0){for (int i = 0; i < apps.size(); i++){mNameList.add((String) apps.get(i).loadLabel(packageManager));//获取应用名称mDrawableList.add(apps.get(i).loadIcon(packageManager));      //获取应用图片System.out.println(apps.get(i).loadLabel(packageManager));}}

这样就可以过滤出category为Intent.CATEGORY_LAUNCHER的所有的应用了
