* Licensing fee comes after record $5 bln EU antitrust fine
* Smartphone makers free to use rival versions of Android
* Changes come into force on Oct. 29 in Europe

BRUSSELS, Oct 16 (Reuters) - U.S. tech giant Google will charge smartphone makers a licensing fee for using its popular Google Play app store and also allow them to use rival versions of its Android mobile operating system to comply with an EU antitrust order.
Google, an Alphabet subsidiary, announced the changes on Tuesday, three months after the European Commission handed it a landmark 4.34 billion euro ($5 billion) fine for using its popular Android mobile operating system to hinder rivals.
The company said the licensing fees will offset revenue lost as a result of its compliance efforts.
"Since the pre-installation of Google Search and Chrome together with our other apps helped us fund the development and free distribution of Android, we will introduce a new paid licensing agreement for smartphones and tablets shipped into the EEA," Hiroshi Lockheimer, senior vice president for platforms and ecosystems, said in a blog.
The European Economic Area (EEA) comprises the 28 EU countries, plus Iceland, Liechtenstein and Norway.
Manufacturers taking on Google Play and other Google services such as Gmail, YouTube and maps, can also install the Google Search app and the Chrome browser free of charge.
"Android partners wishing to distribute Google apps may also build non-compatible, or forked, smartphones and tablets for the EEA," Lockheimer said.
The changes will apply on Oct. 29 for all new smartphones and tablets sold in the EEA.
EU antitrust enforcers in their July decision said Google's anti-competitive behaviour, which dated to 2011, included forcing smartphone makers to pre-install Google Search and its Chrome browser together with its Google Play app store on their Android devices.
Another illegal tactic included paying manufacturers to pre-install only Google Search and preventing them from using rival Android systems. ($1 = 0.8636 euros) (Reporting by Foo Yun Chee Editing by David Goodman)
