getPackageManager().clearPackagePreferredActivities(defaultLauncherPackgeName);

Added:

If you want to set your launcher as default, try:

     ComponentName cN = new ComponentName(mContext, FakeHome.class);
     p.setComponentEnabledSetting(cN, PackageManager.COMPONENT_ENABLED_STATE_ENABLED,             PackageManager.DONT_KILL_APP);

     Intent selector = new Intent(Intent.ACTION_MAIN);
     selector.addCategory(Intent.CATEGORY_HOME);
     mContext.startActivity(selector);

     p.setComponentEnabledSetting(cN, PackageManager.COMPONENT_ENABLED_STATE_DISABLED,            PackageManager.DONT_KILL_APP);

And in AndroidManifest.xml:

    <activity
         android:name="com.test.FakeHome"
         android:enabled="false" >
         <intent-filter>
             <action android:name="android.intent.action.MAIN" />

             <category android:name="android.intent.category.HOME" />
             <category android:name="android.intent.category.DEFAULT" />
         </intent-filter>
     </activity>
