How can I dynamically detect whether my application is system or normal?

Question

How do I differentiate between a system app and a normal app ? I looked through android PackageManager and could not find any.

Edit: I want to differentiate via code.

if(system app) {
  //do something
}
else{
   //do nothing
}

You could try using the flags available in the ApplicationInfo class (android.conent.pm). For example:

...
PackageManager pm = getPackageManager();
List<ApplicationInfo> installedApps = pm.getInstalledApplications(0);

for (ApplicationInfo ai: installedApps) {

    if ((ai.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
        // System app - do something here
        ...
    } else {
        // User installed app?
    }
}
