Android perforamnce is ok but compared to C/C++ sometimes it is slower 4-20 times depending on what is your program doing... Problem is that it is Dalvik is not using JIT but interpreter... Hopefully Google will release JIT soon and performance will be much better.

One tool I really like to see where in my apps I can improve performance is traceview. Great tool that can show you which methods are slow... http://d.android.com/guide/developing/tools/traceview.html you can read more. Also I recommend you to use Ubuntu and dowload soruce code... so that if needed you can use native code for processor intensiveoperations... PMD is also good and can be used with Android...

pros: good looking, small, crisp screen

cons (so far): wifi seems very slow, haven't tried wireless yet,
interface close to as good as iPhone, but still seems a little rough - maybe I'll get used to it?
seems strange that it didn't come with a game or two?

I'd love to hear what you guys think!



HTC Magic is good phone but on G1 and HTC Magic I am missing features I have on my Sony Ericsson phone. Camera could be better, music player, it can be really hard to see display outside on a sunny day... But Android is great OS for developers and phone users... Android Market is one of its best fatures beside great API's.

Like Tim said you can use GPS emulator in Sun's, Sony Ericsson's, NOKIA's... SDK... I use that emulator to test if it works and then test on real devices... Not only Nokia will have all smartphones with GPS... Today Sony Ericsson has Xperia X1 Windows smartphone with JME implementation and GPS but also other cheaper phones like W760 or C902... have GPS. It is also possible to buy plugable GPS device to phones that don't have built in GPS...

But as far as I know Nokia will not support JME on S60 but only on S40 so it won't help you much if they have GPS devices on all S60 phones... There is still C++ there or maybe plain Java but we'll see...

it depends on the phone model... according to JTWI (JSR 185) it should be minimum 30 KB...

Hi!

Use RMS or if your phones have file system then use JSR 75 (javax.microedition.io.file)...

Hi!

I intend to take SCMAD and to be on the safe side I think that it will be good to buy SCMAD preparation/training kit. For SCEA exam I used Whizlabs kit and it was ok but I don't know whether Whizlabs SCMAD preparation kit is ok or you know some better alternative???

Any suggestions?
Hi!

What is the name of the book? When it will be possible to buy it on www.amazon.com ?
But if you are intermidiate Java programmer you can also read Kicking Butt with MIDP and MSA: Creating Great Mobile Applications. Is not detailed as Core J2ME but has examples with latest API's. Beginning J2ME is somwhere in the middle between Core J2ME and Kicking Butt with MIDP...
Murach's JSP/Servlets book is good and easy to follow with simple examples and little web app at the end... Core Servlets and JSP is good too but if you already have HF Servlets and JSP use that book. Find source code of some web app that uses JSP/Servlets and use it with your book.

I don't think that you can write your app in Java ME and then run it on iPhone... As far as I knwo iPhone doesn't support JME. I have heard that people managed to run Java on iPhone but...
