Answer 1

You can disable a component via PackageManager.setComponentEnabledSetting() , which will have the effect of removing it from the Launcher.

List component names in Android:

Following is the code to get the list of activities/applications installed on Android

final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List packageList = context.getPackageManager().queryIntentActivities( mainIntent, 0);

You can get the component names from packageList.

ComponentName :

Identifier for a specific application component ( Activity , Service , BroadcastReceiver , or ContentProvider ) that is available. Two pieces of information, encapsulated here, are required to identify a component: the package (a String) it exists in, and the class (a String) name inside of that package.

set permission in AndroidManifest.xml

<uses-permission android:name="android.permission.CHANGE_COMPONENT_ENABLED_STATE>

From Android Developers :

Allows an application to change whether an application component (other than its own) is enabled or not.

Note: Not for use by third-party applications.

Answer 2

Try this Code:

PackageManager p = getPackageManager();
p.setComponentEnabledSetting(getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

Or try this:

PackageManager pm = this.getPackageManager();
pm.setComponentEnabledSetting(new ComponentName("com.google.android.talk",
    "com.google.android.talk.LAUNCHER"),
    PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
    PackageManager.DONT_KILL_APP);

Note: The icon may not be gone until the next reboot. So reboot your device and see the applied effect!
