我是靠谱客的博主想人陪薯片，最近开发中收集的这篇文章主要介绍Android 获取本地已安装的应用程序，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

有一个需求获取本地指定的系统App和已经下载的App列表：

实现非常简单，首先获取本机已安装的App，然后把我们指定的系统App过滤掉，存入一个List集合中，然后把其他的系统App过滤掉，剩下的在放入，另外一个List集合中，组合就Ok。

贴下主要代码：

public class AppUtils {

    public static final String PACKAGE_OTA="com.sunmi.ota";
    public static final String PACKAGE_MARKET="woyou.market";
    public static final String PACKAGE_HARD_WARE_KEEPER="com.woyou.hardwarekeeper";
    public static final String PACKAGE_UDH="com.woyou.udh";
    public static final String PACKAGE_SETTING="com.android.settings";

    /**
     * 过滤自定义的App和已下载的App
     * @param packageManager
     * @return
     */
    public static List<AppInfo> scanInstallApp(PackageManager packageManager,int filterType) {
        List<AppInfo> myAppInfos = new ArrayList<AppInfo>();
        List<AppInfo> mFilterApps = new ArrayList<AppInfo>();
        try {
            List<PackageInfo> packageInfos = packageManager.getInstalledPackages(0);
            for (int i = 0; i < packageInfos.size(); i++) {
                PackageInfo packageInfo = packageInfos.get(i);
                //过滤指定的app
                String tempPackageName=packageInfo.packageName;
                if(tempPackageName.equals(PACKAGE_OTA)||tempPackageName.equals(PACKAGE_MARKET)||tempPackageName.equals(PACKAGE_HARD_WARE_KEEPER)
                        ||tempPackageName.equals(PACKAGE_UDH)||tempPackageName.equals(PACKAGE_SETTING)){
                    AppInfo appInfo = new AppInfo();
                    appInfo.setAppName((String) packageInfo.applicationInfo.loadLabel(packageManager));
                    if (packageInfo.applicationInfo.loadIcon(packageManager) == null) {
                        continue;
                    }
                    appInfo.setAppIcon(packageInfo.applicationInfo.loadIcon(packageManager));
                    mFilterApps.add(appInfo);
                    continue;
                }

                //过滤掉系统app
                if ((ApplicationInfo.FLAG_SYSTEM & packageInfo.applicationInfo.flags) != 0) {
                    continue;
                }

                AppInfo appInfo = new AppInfo();
                appInfo.setAppName((String) packageInfo.applicationInfo.loadLabel(packageManager));
                if (packageInfo.applicationInfo.loadIcon(packageManager) == null) {
                    continue;
                }
                appInfo.setAppIcon(packageInfo.applicationInfo.loadIcon(packageManager));
                myAppInfos.add(appInfo);
            }
            myAppInfos.addAll(mFilterApps);
        } catch (Exception e) {
           e.printStackTrace();
        }
        return myAppInfos;
    }

由于内容很简单，就不上其他源码了。
