Android simple way to determine if a APK has been installed _android

The example in this article describes how Android simply determines whether a APK has been installed. Share to everyone for your reference, specific as follows:

Privateboolean isappinstalled (String uri) {
Packagemanager pm = Getpackagemanager ();
Boolean installed =false;
try{
Pm.getpackageinfo (uri,packagemanager.get_activities);
Installed =true;
} catch (Packagemanager.namenotfoundexception e) {
installed =false;
}
return installed;
}

Just use this method to check the name of the application package you need to determine:

if (isappinstalled ("Com.yourpackage.package")) {
//app installed
}
else{
//app not installed
}
