Get app info for Android device installed

This article describes how to get app information that's already installed on your device, including: App Name, package name, icon, and so on.

Once you have a list of information, you can also launch the corresponding app by selecting a record!

1. Code implementation

Package Com.example.showapplist;import Java.util.arraylist;import Java.util.list;import Android.content.pm.applicationinfo;import Android.content.pm.packageinfo;import Android.content.pm.packagemanager;import Android.os.bundle;import Android.support.v4.app.listfragment;import Android.view.layoutinflater;import Android.view.view;import Android.view.viewgroup;import Android.widget.ListView ;p ublic class Applistfragment extends Listfragment {private arraylist<appinfo> applist = new arraylist<appinfo& gt; (); @Overridepublic void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Getapplist (); Appadapter adapter = new Appadapter (this.getactivity (), applist); Setlistadapter (adapter);} @Overridepublic View Oncreateview (layoutinflater inflater, ViewGroup container,bundle savedinstancestate) {return Super.oncreateview (Inflater, container, savedinstancestate);} @Overridepublic void Onlistitemclick (ListView l, View v, int position, long ID) {//Start the selected application StartActivity (aPplist.get (position). Appintent);}  /** * Get non-system app information list */private void Getapplist () {Packagemanager pm = this.getactivity (). Getpackagemanager ();//Return a list Of all packages that is installed on the device. list<packageinfo> packages = pm.getinstalledpackages (0); for (PackageInfo packageinfo:packages) {//Judgment System/Non-system application if ((PackageInfo.applicationInfo.flags & applicationinfo.flag_system) = = 0)//non-system Application {AppInfo info = new AppInfo (); Info.appname = PackageInfo.applicationInfo.loadLabel (PM). toString (); info.pkgname = Packageinfo.packagename; Info.appicon = PackageInfo.applicationInfo.loadIcon (PM);//Gets the app installation package intent, which is used to launch the app info.appintent = Pm.getlaunchintentforpackage (Packageinfo.packagename); Applist.add (info);} else {//System Application}}}}

Among them, the Getapplist () method obtains the application information installed by the current device.

Determine whether an application is a system application or a non-system application using the following code:

Judging System/Non-system applications if ((PackageInfo.applicationInfo.flags & applicationinfo.flag_system) = = 0)//non-system application {} else {//System Application }

Get the intent you need to start another application by using the following code:
