之前的文章向大家介绍了几个项目中常用的实用功能，那么在这篇文中，我将向大家介绍如何获取Android手机中已经安装的手机应用程序，好了，废话不多说，直接上代码
private String getInstalledAppListAsString(){ PackageManager pm = context.getPackageManager(); List<ApplicationInfo> apps = pm.getInstalledApplications(PackageManager.GET_GIDS); StringBuffer stringBuffer = new StringBuffer(); for (ApplicationInfo app : apps) { if(pm.getLaunchIntentForPackage(app.packageName) != null) { // apps with launcher intent if((app.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) == 1) { // updated system apps } else if ((app.flags & ApplicationInfo.FLAG_SYSTEM) == 1) { // system apps } else { // user installed apps stringBuffer.append(app.packageName).append(';'); } } } return stringBuffer.toString(); }下面我们看看具体如何获取各个应用的相关信息呢
package cn.lyz.mobilesafe.domain;import android.graphics.drawable.Drawable;/** * 获取的应用基本信息实体类 * @author liuyazhuang * */public class AppInfo {//图标private Drawable app_icon;//应用名称private String app_name;//应用版本号private String app_version;//应用包名private String packagename;//是否是用户appprivate boolean isUserApp;public AppInfo() {super();// TODO Auto-generated constructor stub}public AppInfo(Drawable app_icon, String app_name, String app_version,String packagename) {super();this.app_icon = app_icon;this.app_name = app_name;this.app_version = app_version;this.packagename = packagename;}public AppInfo(Drawable app_icon, String app_name, String app_version,String packagename, boolean isUserApp) {super();this.app_icon = app_icon;this.app_name = app_name;this.app_version = app_version;this.packagename = packagename;this.isUserApp = isUserApp;}public Drawable getApp_icon() {return app_icon;}public void setApp_icon(Drawable app_icon) {this.app_icon = app_icon;}public String getApp_name() {return app_name;}public void setApp_name(String app_name) {this.app_name = app_name;}public String getApp_version() {return app_version;}public void setApp_version(String app_version) {this.app_version = app_version;}public String getPackagename() {return packagename;}public void setPackagename(String packagename) {this.packagename = packagename;}public boolean isUserApp() {return isUserApp;}public void setUserApp(boolean isUserApp) {this.isUserApp = isUserApp;}@Overridepublic String toString() {return "AppInfo [app_icon=" + app_icon + ", app_name=" + app_name+ ", app_version=" + app_version + ", packagename="+ packagename + ", isUserApp=" + isUserApp + "]";}}
