Google Play and Android Apps Are Coming to (Recent) Chromebooks, Chromeboxes, and Chromebases
There’s been talks about Android and Chrome OS merging for many years, and while it’s unclear whether it will ever happen, both operating systems’ features are converging, with the latest development officially bringing Android apps and the Google Play store to Chromebooks. Developers will have very little to modified on their Android apps, except possibly setting touchscreen support, and a few other options in the manifest file. Google listed a few benefits of Android apps on Chromebooks: Android Apps can be shown in 3 different window sizes Users can multi-task with multiple Android apps in moveable windows along with a full desktop browser within Chrome OS interface. Keyboard, mouse, and touch input will seamlessly work together Users will get Android notifications on their Chromebooks Android apps benefit from the Wifi or Bluetooth connectivity setup by the user or the administrator File sharing is seamless between Chrome and Android apps through […]

Xiaomi Mi Box Comes to the US with Android TV 6.0 Running on Amlogic S905X Processor
Xiaomi Mi Boxes have been available in China for a couple of years, and the only way to ship them to the rest of the world was to purchase via Chinese e-retailers. Xiaomi and Google have now worked together to bring Mi Box with Android TV 6.0, instead of the usual Chinese MIUI TV interface, to the US, and possibly to other countries. Xiaomi Mi Box (US) specifications: SoC – Amlogic S905X-H quad core ARM Cortex-A53 @ up to 2.0GHz with penta-core Mali-450MP GPU @ 750 MHz System Memory – 2GB DDR3 Storage – 8GB eMMC flash Video Output – HDMI 2.0a up to 4K @ 60 Hz with HDCP 2.2 and CEC support Audio Output – HDMI, optical S/PDIF and 3.5mm audio jack Video Codecs – VP9 Profile-2 & H.265 MP-10 up to 4K @ 60 fps, H.264 AVC up to 4K @ 30 fps, H.264 MVC up to […]
Android N Developer Preview 3 Adds VR Support, Instant Apps, and Sustainable Performance Mode
Google has also unveiled the third Android N Developer Preview at Google I/O 2016, and the first “beta quality” release, available on Nexus 6, 9, 5X, 6P, Nexus Player, Pixel C, and Android One as a “seamless updates” if you opt-in to the Android Beta Program in order to get an over-the-air update with the very latest firmware. Google wants Android N to be faster, safer and more productive. The first two previews addressed performance with a new JIT compiler and Vulkan 3D graphics API support, productivity with multi-window support and direct reply from notifications, as well as security thanks to seamless updates bringing the latest security patchsets to your phones in a timely manner. The third preview brings fixes, and some interesting new features: VR Mode in Android – Google has modified and augmented the Android stack in N to reduce lag between sensor data readings (e.g. head motion) […]
Android Wear 2.0 Developer Preview Release
Google I/O 2016 has started, and among several announcements, Google released Android Wear 2.0 develop preview which according to the company is the “most significant update” since the launch of Android Wear two years ago. Some noticeable changes include: Standalone apps – Android Wear apps can now access the Internet directly over Bluetooth, Wi-Fi, or cellular, without relying on a paired smartphone or tablet.

Programming ESP8266 Boards with a Smartphone
In recent days, I wrote about low cost MCU boards such as the $2 BluePill, and the One Dollar Board project, but several people commented that while the board themselves are very cheap, it might still be a problem in some developing countries, where access to computers cannot be taken for granted. So person suggested that such initiative would work better in some countries if programming was possible via a smartphone instead. Is that true? According to a 2014/2015 study by Pew Research Center, there is some truth to it, but it varies greatly between countries. For example, 55% of Brazilian adults own a computer at home, while only 24% own a smartphone, but in Kenya only 8% own a computer at home, while 15% own a smartphone. Some devices in the “cellphones but not smartphones” might be feature phones with WiFi and a web browser. Anyway ideally a low […]
Beelink BT7 mini PC Powered by Atom x7-Z8700 Processor Features 4GB RAM, Up to 320 GB SSD
When I reviewed Voyo V3 mini PC based on Intel Atom x7-Z8700 processor, I was quite satisfied with the experience thanks to very fast storage with decent capacity (120 GB), the fastest Cherry Processor available combined with 4GB RAM which made for a pretty good experience under Windows 10 for just under $200. However, the mini PC networking capabilities suffer, with the lack of Ethernet, and WiFi limited to 802.11n @ 2.4 GHz. Beelink has been working on their own Atom x7 mini PC, namely Beelink BT7, with both Gigabit Ethernet & dual band WiFi, as well as various SSD options up to 320 GB. Beelink BT7 mini PC specifications: SoC – Intel Atom x7-Z8700 Cherry Trail quad core processor @ 1.60 GHz/2.40 GHz (turbo) with Intel Gen8 HD graphics @ 600MHz with 16EU (2W SDP) System Memory – 4 GB DDR3 Storage – 64, 128, or 320 GB SSD […]
