I want to make a list of installed and system applications. system applications means the pre-installed applications (applications which are installed at the time of manufacture).
For this i categorized all the apps using (ApplicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0
- which are system apps and others are installed apps.
Now my problem is i want to launch these apps on click of list items.But i could not launch system apps like Contacts,Dialer etc...
How to launch system apps programmatically or how to filter out launchable system apps?
I could not found exact answer.But i think it will helpful
List<PackageInfo> list = packageManager.getInstalledPackages(0);
for (PackageInfo pi : list) {
try {
ApplicationInfo appInfo = getPackageManager() .getApplicationInfo(pi.packageName, 0);
//check whether the app is launchable or not
if (packageManager .getLaunchIntentForPackage(appInfo.packageName) != null) {
//check whether the app is an installed / system app
if ((appInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
//system apps.........
} else {
//installed apps............
}
}
} catch (Exception e) {}
}
