Hello
For Windows Phone I use Windows Phone Developer Power Tools and I'm looking for alternative for Android. I want to monitor cpu, ram, I/O and others parameters from Android device(or virtual devices) connected to my PC. There is some application that has features I'm talking about ?
With Android Studio Android Monitor you are able to monitor Memory, CPU|GPU and Network...
If you want something more elaborate we are developing a performance monitoring platform for Android and iOS you can use to know what's going on with your app performance in prodcution. Monitoring thousand of different users with different devices and different Android OS versions or your own app different verisons.
The platform is still under development but you can join the mailing list if you want to know when the final release is published.
Once we finish the project you could see something like this:

I'm starting the studies about android development with Android Studio and I was wondering if it's possible to build applications only running code on a physical device or do I need to emulate others devices in order to avoid errors, etc.?
The Android Studio emulator barely runs in my machine, so I need to know if it is essential for the apps development or if there are other alternatives.
If you need to run on different versions of Android, just what #CrazySports101 mentioned, but also test different screen sizes & resolutions to check UI responsiveness, it would be better to use emulators.
Obviously, you can start development using either a single emulator or physical device, but during your final testing stages, it would make sense to use emulators to test all your device specific usecases.
And yes, there are few limitations with using an emulator, like it cannot emulate network connectivity, other real-time data, such as GPS, sensors, battery issues, etc. Or usecases such as calling, receiving SMS is not possible as well.
If you have a physical device, you can just use that. No need to run the emulator at all. An emulator is mostly used because it is convenient and easy to test different versions of android. For example, some libraries/UI component may behave differently on different phones.
It is better to use a physical device if your app is using radios like Bluetooth etc.
If you just started to learn android studio and your device can barely run emulator, I would recommend you to go for physical device. Emulator makes you possible to try your product on different version of android and screen ratios, but you can not emulate network connectivity, real-time data, GPS, sensors, battery issues, calling, receiving SMS is not possible. But if you are trying to launch a product in a market you should go for emulator as you would need to try your product on different versions as well.
I want to start Mobile Phone development, but I am very very new to this area, I have 3 choices: iPhone, Nexus One and Windows Phone. I believe Nexus one atracts me more. But I have never bought a smart phone. My questions is: If a buy one Nexus One from Best Buy store, can I use it for developing Android applications?
I appreciate your help, nobody helps me with this question and I am a novice in smart phones.
Thnak you

For the most part you do not need a device to start doing mobile development. You can download the Android SDK complete with an emulator here: http://developer.android.com/sdk/index.html
If you're not sure which kind of development you'd like I'd recommend downloading the toolkits for all the major ones, trying them out, and then decide.
Android
Windows Phone
iPhone
Blackberry
You don't develop mobile software ON a mobile device. You use them to test.
If your choice is Android vs. Windows vs. iOS, then you need to decide what kind of software you will be writing.
For native apps, all 3 use very different development platforms (java vs. .net vs. objective-c).
If you're going to go the HTML5 + Phonegap route, then it really doesn't matter. And you really don't need a physical device anyways...you can always test on simulators.
If you want to do ANY app dev for iOS, though (be it native or phonegap) you WILL need OSX on a desktop/laptop computer.
First decide what operating system you want to work on as DA suggested. If you have decided to develop applications for Android then iPhone and Windows phone is of no use to you.
Only those devices having Android Operating System you can use, Nexus One or Samsung GalaxyS are good options.
But before buying anything you can start developing applications as there is emulator provided which does most of the work that a device does.
I really want to get into Android programming but I only have access to company resources right now. I have the money right now to purchase a XOOM or a development laptop. Is it possible to compile Android apps using the command line on the Xoom while using other apps to write the program files.
What would seem like a dream environment would be if I purchased a XOOM and a BlueTooth Keyboard. Am I dreaming? Developing using older Android devices was naturally limited by the screen space of the device and the underlying hardware also.
No, as far as I know, you cannot develop Android applications from within Android. You will need a Windows, Mac, or Linux desktop environment to develop Android applications. Visit the Android Developer site for additional info on the SDK.
Go for the development laptop, and test your applications on the emulator. Initially you can get friends to test them out on their android for you, and hopefully by the time you make something important enough you will be able to afford your own android.
Check out AIDE. It can build and deploy apps natively on Android.
Google doesn't have a version of the SDK that runs on an android device, although as devices become more powerful this would be a pretty awesome thing to have.
You'll want the laptop, since it can emulate different android devices.
Buy the laptop and get a cheap phone on craigslists.
Although, the XOOM emulator doesn't work at all, so if you want to develop specifically for that tablet it's a good idea to buy it. It's impossible to emulate android 3.0 on any computer on earth :)
Can I use any Android Phone for app development? Here in the Philippines, there are many available mobile phones with Android installed. But I want to buy the cheapest phone available (which I think is Samsung i5500 Galaxy 5). Thanks in advance!
You can use any android powered device for development, just make sure it has Development menu option. To check go to Menu -> Settings -> Applications -> Development. If there is somewhat like USB Debugging option you can use device for the development.
Why not use the actual dev kit? There is a complete setup with virtual phone included that you can run as an eclipse plugin.

I think any Android platform based phone will be OK.
Yes you can, and I would definitely recommend using a real phone. The emulator is excellent, but somewhat slow for a number of applications that require hardware (OpenGL comes to mind). Even a G1 tends to be faster than the emulator for certain things. If you're creating an app that uses Bluetooth, there's no way to do so on the emulator currently. Konstantin's directions are good for actually setting up the phone.
You need to understand one thing before you buy the phone. What version of Android SDK you will be using for to develop the app. If say, you are developing the app for cupcake and above, you better have a phone with cupcake version. But if you have Froyo phone, you will not be still able to run the app, but some depreciated functions might not be available and your app may crash.
If you want to develop in Windows there is a list of devices available for which the USB drivers work: USB Driver for Windows
If you don't need the GSM part you could also think about using the Archos 5 Internet Tablet, which is a Android powered media player and supports ADB (Android debug bridge) as well
Is it possible to install Android in a normal mobile phone?
I have Sony Ericsson Naite which has only key pad interface (No touch). I would like to install Android in my phone for experimenting with it. It will be great if its possible to dual boot Android with Symbian :-).
Do we need any other special hardware to install operating system in a mobile phone? Will Android work on a key-pad mobile?
Any pointer/suggestion is appreciated.
Thank you in advance.
The Naite is a fairly simple handset running on the Sony Ericsson JP8 platform.
End users are not supposed to be able to update the firmware on the phone.
Only Sony-Ericsson partners are supposed to get the PC software to update the firmware and only Sony-Ericsson is supposed to be able to create new firmwares.
(maybe you can hack the phone so you get it to boot on android or symbian but that's going to be unsupported behavior that nobody will guarantee)
If you want to experiment with creating your own android firmwares, I suggest buying an ADP2 handset from google.
If you want to experiment with creating your own Symbian firmwares, I suggest buying a Texas Instrument Zoom 2 device since it is the reference platform for Symbian.
The Zoom 2 seems to also support Android, by the way.
If you just want to experiment with application development on both platforms, I suggest using the two SDKs and emulators first.
There are some pretty cheap Symbian phones out there, particularly in the Series60 3rd edition range and, depending on where you live, you might even be able to find a Pay-As-You-Go Android phone like the Pulse.
I STRONGLY encourage you to go visit the XDA Forums and visit their Android sections for this kind of information.
