How to enable and disable a component?

Question

My initial question was basically something along the lines of this: Clearing and setting the default home application

That question was answered to my satisfaction, however, the thing I'm having difficulty understanding in the answer is how do you enable and then disable a component from the manifest in the java code?

By using package manager you can enable or disable component declared in manifest file There are two flag PackageManager.COMPONENT_ENABLED_STATE_DISABLED for disable component and PackageManager.COMPONENT_ENABLED_STATE_ENABLED for enable component.

PackageManager pm = getApplicationContext().getPackageManager();
ComponentName componentName = new ComponentName("com.app",
    ".broadcast_receivers.OnNetworkChangedReceiver");
pm.setComponentEnabledSetting(componentName,
    PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
    PackageManager.DONT_KILL_APP);

Android manifest:

<receiver
  android:name=".broadcast_receivers.OnNetworkChangedReceiver"
  android:enabled="true"
>
  <intent-filter>
    <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
  </intent-filter>
</receiver>

Official documentation: setComponentEnabledSetting

The same code both enables and disables the component or is there a subtle difference? – scibor Jul 01 '13 at 17:14
for disable component PackageManager.COMPONENT_ENABLED_STATE_DISABLED and for enable component PackageManager.COMPONENT_ENABLED_STATE_ENABLED – Pawan Yadav Jul 01 '13 at 17:15
Does this disable the component just for the active profile, or for all the profiles on the device? If all profiles, is there a way to do it per profile? – Gunanaresh Feb 11 '16 at 19:04
a little more generic approach: – Noam Segev Sep 04 '16 at 08:20

taking Pawan approach to more generic implementation:

public static void setComponentState(Context context, String packageName , String componentClassName, boolean enabled)
{
    PackageManager pm  = context.getApplicationContext().getPackageManager();
    ComponentName componentName = new ComponentName(packageName, componentClassName);
    int state = enabled ?  PackageManager.COMPONENT_ENABLED_STATE_ENABLED :  PackageManager.COMPONENT_ENABLED_STATE_DISABLED;
    pm.setComponentEnabledSetting(componentName,
            state,
            PackageManager.DONT_KILL_APP);

}
