DEVEL­OP­ING AN­DROID WE­BAPPS US­ING HTML5 TECH­NOLO­GIES

We­bapps are easy to de­velop and with them, it is ac­tu­ally pos­si­ble to ‘write once, and de­ploy ev­ery­where’.

Any­one who has used GMail or the likes knows what a We­bApp is. It is a browser-based ap­pli­ca­tion served over the In­ter­net (or any other net­work). One dif­fer­ence be­tween a Web page and a We­bApp is that the lat­ter, typ­i­cally has more in­ter­ac­tive op­tions like but­tons, icons and alerts, like a reg­u­lar ap­pli­ca­tion. While the ini­tial ver­sions of We­bApps needed an al­ways-on In­ter­net connection, the lat­est We­bApps can be used just like na­tive apps, with lim­ited or no In­ter­net connection. Some ex­am­ples of the best We­bApp al­ter­na­tives to na­tive apps are from Google, Face­book, Twit­ter, Citibank, Fi­nan­cial Times and paytm.com.

A bless­ing to We­bApp de­vel­op­ers is ‘We­bKit’, the lay­out en­gine com­mon to An­droid and Ap­ple Sa­fari browsers. This makes a We­bApp avail­able to a wide range of mo­bile de­vices in the mar­ket.

The We­bApps trend

Web 2.0 tech­nolo­gies made the power of na­tive desk­top ap­pli­ca­tions avail­able to browser-based We­bApps. Google Docs, for ex­am­ple, gives users al­most the same brainer to pre­dict the same trend on mo­bile de­vices. In fact, ac­cord­ing to ex­perts, what took three decades mo­bile de­vices.

The con­ver­gence of three im­por­tant trends is key to the evo­lu­tion of We­bApps on mo­biles. While bet­ter­per­form­ing smart­phones favour both na­tive apps and We­bApps equally, the de­clin­ing tar­iffs of mo­bile data ser­vices and the stan­dard­i­s­a­tion of im­proved Open Web tech­nolo­gies favour We­bApps.
