Yahoo! Japan Releases Yahoo! Browser for Android

Yahoo! Japan, the largest and the most popular website in Japan, offers a new web browser for Android for free. The name is Yahoo! Browser.

It starts from a speed dial page like Opera,

Do Yahoo! Search on Yahoo! Browser,

The browser offers semicircular menu, which shows up when you touch the either side edge of screen. Yahoo! Japan says that it makes single hand operation easier, which is important for train commuters (which means majority of Japanese in urban area) who often can not use both hands on crowded trains.

Log-in status will be shared between the browser and Yahoo! Widgets for Android, which enables, for example, jump from a widget to Yahoo! pages on the browser without additional authentication.

The browser also has “Read it later” feature, voice recognition search and phishing-site detector. The supported Android versions are 2.x and above except 3.x.

The browser’s user-agent has “Mozilla”, “AppleWebKit”, “Mobile Safari” and “YJApp-ANDROID”, so it seems to be built on Android’s standard browser.

Cellphone Java App Emulator On Javascript/HTML5

Before smartphone, there were feature phone applications. Java MIDP is one of the application environment used on Softbank/Wilcom/KDDI au in Japan, and also on Motorola feature phone, etc. Android is known to use Java-derived environment. Google made different virtual machine Dalvik with avoiding using Sun’s(and now Oracle’s) Java, but Java/CLDC profile MIDP is authentic standard which you could develop cellphon applications.

Because of its long history, there are tons of MIDP applications exist on those cellphone. MIDP is very limited in comparison with Java for regular PCs, but it was well chosen for the limited cellphone environment.

Helped both by hardware and software improvement, a Japanese programmer Yukoba, who says himself as “Virtual machines on JavaScript and ActionScript otaku”, released this “Java MIDP implementation on HTML5 and Flash” at Firefox Developers Conference 2010 in November, where jQuery developer John Resig attended.

His compiler generates JavaScript from MIDP Java class files, so the applications written for feature phone can be run on HTML5 browsers – Firefox. He also developed a compiler to ActionScript, to run it on Internet Explorer 8.

He also launched a showcase-site where you may play about 20 games and utilities made on Java MIDP.

He seems to be working on improvement of the emulator now. As I said above, there are a lot of MIDP application resources in Japan so it is good to run them on the modern web browsers.
