Re: [android-developers] Re: Use Mobile Device CPU or Server CPU
Use REST for the client/Server communication - it's lightweight and well defined. There's plenty of resources available on the internet with examples. Return JSON data from the server to the client - again it's a well defined method for returning structured data. Start simple - forget threading and performance - just get it working first. Use something simple server side to write your app in - PHP/Rails - whatever you feel comfortable writing. When it comes to thinking about performance: 1) Start with the server - are you using the right type of webserver (Apache, ngnix, etc) is the config right (gzip headers, cache lifetime, etc) and do you have simple accelerators installed (APC). 2) Measure profile your app on the server - where is it spending most of it's time, can you optimise the code, cache locally expensive operations (using something like memcached). Start with the areas that will have the biggest impact on performance based on your profiling. Then start thinking about how you app will scale over time as the traffic increases. Will you be scaling up (adding more resources to the server) or out (adding more servers) - or a combination of the two.

The gps coordinate are sent to the server which computes the complete list of restaurant nearby. Pros : - You can make your app available on any platform(iphone, facebook app) without a need to change the server side code. - You don't use any resources on the phone either CPU or memory(no databases), good for users. - No need for synching overhead and no chance of out of synch data Cons : - Can't work when the mobile is offline - You are not using the resources of the individual phones. If your app is successful, the load on your server could get quite high Obviously, the first con, isn't really a con, that would be a very good problem to have if you know you are going to monetize your app :D Maybe you can use some caching techniques to relieve some of the load on the server. For example if someone sends gps coordinate in San Francisco, download a zip file of all the restaurants there. And then use that local database for a few days or so before resynching. That removes one of the pros in my list, but since it also remove the first con, that doesn't count :D Yahel -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] How to find email of the current user
Direct them to your website to reset their password - use Google oAuth. No need to send them an email.

For example, if may depend on the hardware what kind of audio abilities you get, whereas in the iPhone they are all a standard set by Apple. But right now the smallest latency is around 100ms or so buffers, which is way too much (slow) Fortunately I'm making apps that really dont care about latency, they are sample driven (my main app is Electrum Drum Machine), they only have latency problems when trying to play live with the touchscreen (and I think some of that latency is from the screen hardware itself). So for me processor power is most important right now. Having access to NDK audio would be nice, but not really necessary, since I've found that calling JNI and passing a buffer back from Native Code doesn't have as much overhead as most people think, I've had speed increases of up to 100 or more by doing so, native code is just that much faster than the Dalvik java! -niko On Mar 17, 11:32 am, Kevin Duffey andjar...@gmail.com wrote: I too wanted to work on some audio apps.. I had bought BeatMaker on iPhone, and wanted to do something similar for Android. It's a blind guess, but unless the google team has a massive update in 3.0 coming by end of year, I would guess that we wont get the audio/low latency capabilities of iPhone for at least 2 years. I can not imagine why, but games and audio, even tho they are huge on the iPhone, seem to be lacking interest from the Android team as being important. From the various forum posts I've seen over the last several months, it seems like the JVM doesn't have a JIT, so its actually slower than J2ME JVMs although the hardware is faster so it is probably comparable. Most basic apps run fine, but games struggle to keep solid framerates up do to the GC issues among other things. With a new thread that started a few days ago describing other apps stealing cpu/gc cycles and causing games to hiccup, there seems to be almost no way to provide a solid smooth game that provides any sort of detail all the time. I've not personally played any iphone level game on android other than basic puzzle games, so I am formulating my opinion from various other developers that have posted these issues. I would agree that Android is STILL more appealing to write for than iPhone. I just can't stand the ridiculousness of apple and their changes, forceful removals, etc. It's crap. I don't care if there are 60 million iPhones and only a few million android devices... why suffer thru having to work with objective-c and having to own a mac to write for it, and all their rules.. worrying about whether or not your months of hard work will even get approved. but ya, Android has a long way to go to catch up. If they are even trying to. I don't know if anyone on the android team could comment, but it would be really nice to get some sort of inclination of what is going on with the various threads discussed here about the major shortcomings of android. I would think that android/google would be listening to the developers that plan to write for it, and thus want to focus resources on things like low latency audio, keeping background processes from interfering with foreground real-time games, better 3D support and so on.
