java实现获取安卓设备里已安装的软件包

前端技术 2023/08/09 Java

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app
	private 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;
	}
	
	@Override
	public String toString() {
		return \"AppInfo [app_icon=\" + app_icon + \", app_name=\" + app_name
				+ \", app_version=\" + app_version + \", packagename=\"
				+ packagename + \", isUserApp=\" + isUserApp + \"]\";
	}
}
