Google is extending its Android One programme to Bangladesh, Nepal and Sri Lanka, markets with a combined population of more than 200 million people.

The search giant said that it will work with a “wide range of manufacturers and network partners”, including operator Banglalink and vendors Micromax, Karbonn and Spice from India.

Bangladeshi vendor Symphony will also launch its first Android One device, Roar A50.

Announced earlier this year, Android One is intended to drive the growth of low-cost smartphones in emerging markets, using a common hardware platform and stock Android OS to control costs (devices are also early recipients of software updates).

Android One first debuted in India, explaining the dominance of the country’s domestic device makers on the supplier list. This week, Spice launched a device specifically targeting Hindi speakers.

But when it announced the broadening of Android One earlier this year, Acer, Alcatel OneTouch, Asus, HTC, Intex, Lava, Lenovo, Panasonic and Xolo were also listed as backers.

Previously, Google said that Indonesia, Pakistan and the Philippines are likely to be early targets.

Despite its focus on emerging markets, Android One has also seen launches in more developed markets – Karbonn, for example, is including its Sparkle V in its portfolio for European markets.
