Blackberry - Estimate port of Android app with GPS and Google Maps

Question

Lets say I have an Android app that uses Google Maps and GPS.Uses custom views and timers.

How much time will it require to develop it for Blackberry?

What changes will be required? Can the UI be reused?

I am totally new to Blackberry, though I know Java.

Please help me estimate the time.

Answer 1

Lets state what is different in BlackBerry:

• UI concept is completely different, see UI Guidelines, Blackberry User Interface Design - Customizable UI?
• GPS api differs and is more complicated
• strict j2me JRE 1.4 compliance level instead of extended Java in android (so forget about generics, some math functions, serialization etc)

Also you should do a little prototyping before using Google Maps. See How to use Google Map in Blackberry application? and BlackBerry and map based apps like Yelp and Google Map

Remember also there are many different bb os versions and devices, see Developing for multiple versions of BlackBerry OS

For estimates of reversed porting see port J2ME CLDC Blackberry application to Android I guess (for a newbie) it will be like x3 for your app (for at least Curve Bold and Storm devices).
