Android gets all installed apps for the system

1. Get all installed applications

List<PackageInfo>Packages=Getpackagemanager (). Getinstalledpackages (0);

for(intI=0; I<packages.size (); I++) {
PackageInfo PackageInfo=Packages.get (i);
AppInfo Tmpinfo=NewAppInfo ();
Tmpinfo.appname=PackageInfo.applicationInfo.loadLabel (Getpackagemanager ()). ToString ();
Tmpinfo.packagename=Packageinfo.packagename;
Tmpinfo.versionname=Packageinfo.versionname;
Tmpinfo.versioncode=Packageinfo.versioncode;
Tmpinfo.appicon=PackageInfo.applicationInfo.loadIcon (Getpackagemanager ());
}

2. Judging whether it is a system application

if ((packageInfo.applicationInfo.flags&applicationinfo.flag_system)= = 0)
{
// non-system applications
}
Else

{

System Application

}
