Fetching Application info By using its package name

Question

I am developing an Android application wherein I am trying to check whether an application has been already installed in the device or not. I am fetching the application info using below code. For example to check whether google maps is installed or not, I am using its package name as shown below.

        ApplicationInfo info1 = getPackageManager().
        getApplicationInfo("com.google.android.apps.maps", 0 );

My question is , if at all this package name is changed by google in future, I will have to update the package name and then send an update to users... Other than checking from package name - Is there any other way to get to know if an application is installed or not?

Kindly Help! Thanks!

For an app the package name cannot change. If you change the package name then its a new app. It cant be the same app. — Tarun, Sep 20 '13 at 09:51

This is the code which i use to get app name,lable, icon and package name

Intent intent = new Intent("android.intent.action.MAIN");
            intent.addCategory("android.intent.category.LAUNCHER");
            PackageManager manager = getPackageManager();
            List<ResolveInfo> resolveinfo_list = manager.queryIntentActivities(intent, 0);

            for(ResolveInfo info:resolveinfo_list){

                    //launchComponent(info.activityInfo.packageName, info.activityInfo.name);
                    String lActTitle = (String) info.loadLabel(manager);
                    Drawable d = info.activityInfo.loadIcon(manager);


                    System.out.println("info.activityInfo.packageName>>>>>>>>>>>>>>>" + info.activityInfo.packageName);
                    System.out.println("info.activityInfo.name>>>>>>>>>>>>>>>" + info.activityInfo.name);
                    System.out.println("info.activityInfo.name>>>>>>>>>>>>>>>" + info.activityInfo.name);

                   // RowItem item = new RowItem(d,info.activityInfo.packageName,lActTitle,info.activityInfo.name);
                   //rowItems.add(item);

            }

Using this we can get all the app which is installed and used by user

add all package name to a list and check your app pkg name is avilable or not if pkg name is available then app is installed otherwise not........ – Dhaval Patel Sep 20 '13 at 06:07
