BlackBerry – use GPS and Google maps to evaluate the port of the android app

Suppose I have an Android application using Google maps and GPS. Use custom views and timers

How long does it take to develop it for BlackBerry?

What changes need to be made? Can the UI be reused?

Although I know Java, I'm still new to BlackBerry

Please help me estimate the time

resolvent:

Let's explain the differences of BlackBerry:

>UI concepts are completely different. See UI guidelines, BlackBerry user interface design – customizable UI? > GPS APIs are different and more complex > strict J2ME JRE 1.4 compliance levels rather than extended Java in Android (so forget generics, some mathematical functions, serialization, etc.)

Before using Google map, you should also do some prototype design. See how to use Google map in BlackBerry application? Blackberry and map based apps like yelp and Google Map

Remember that there are many different BB OS versions and devices. See developing for multiple versions of BlackBerry OS

For the estimation of reverse migration, see port J2ME CLDC BlackBerry application to Android. I guess (for a novice) it will be like X3 of your application (at least curve bold and storm devices)
