1.6 Going mobile

GWT is a versatile technology that allows developers to create application UI for desktop, tablet, and mobile consumption. As can be expected, over 98% of apps support desktop browsers, but we found it interesting that tablets had overtaken phones (at least when it came to support from GWT-based apps). In US, the number of apps supporting tablets was as high as 46%, while it was just 34% in Europe.

Hybrid apps?

Server-sideClient-side

Use for

• Offline• Low latency interaction• Maximum scalability

Use for

• Most places ( - 50% cost )• High security• Utilizing full Java platform

Benefits of the both sides, but adds complexity

Far far away, behind the word mountains,

far from the countries Vokalia and

Consonantia, there live the blind texts.

Separated they live in Bookmarksgrove

right at the coast of the Semantics, a

large language ocean.

A small river named Duden flows by their

place and supplies it with the necessary

regelialia. It is a paradisematic country, in

which roasted parts of sentences fly into

your mouth.

Even the all-powerful Pointing has no

control about the blind texts it is an

almost unorthographic life One day

however a small line of blind text by the

name of Lorem Ipsum decided to leave

for the far World of Grammar. The Big

Oxmox advised her not to do so,

because there were thousands of bad

Commas.
