Hi there -
Since the Android platform will be installed on a wide variety of phones/hardware configurations - I was wondering what support Android has for this.
For example - can it support a phone that does not have a screen that toggles between a landscape and portrait bias - and if so, how easy is it to write apps that degrades nicely for this hardware config.
Also - what is the minimum hardware spec that android can run on?
Thanks - Mark

There's no minimum spec that I know of. You can design your program so it will work on touch or non-touch, qwerty keyboard or numeric keypad or no keys at all, trackball or d-pad or wheel, portrait or landscape, gps or no, sensors or no, and so forth.
One of the main ways Android enables this flexibility is through 'alternate resources'. You can create different screen layouts, background images, help text, strings, etc., based on the UI language or hardware configuration on the device. For example in the Sudoku sample program in the book I have a stack of several buttons on the main screen that looks fine in portrait mode but you can't see all the buttons in landscape mode. So in landscape mode I use two columns of buttons. The regular layout is defined in res/layout/main.xml and the landscape mode layout is defined in res/layout-land/main.xml. No code change was needed.
http://d.android.com/guide/topics/resources/resources-i18n.html#AlternateResources goes into much more detail about how this works and where the '-land' suffix comes from.

One of the strange but welcome spin offs from the Visual Studio 2015 launch is that the Microsoft Android emulator is now available as a standalone download. Gta 4 serial key. It works with Visual Studio and Eclipse.

The reasoning behind Microsoft creating and supplying an Android emulator isn't clear, but if you are using Android Studio it is well worth downloading and using if you are working under Windows. In many ways, it is everything that the emulator provided by Google should be and isn't. It is even better than the HAXM accelerated emulator provided by Intel.

There are many reasons why it is better. The first is that it runs under HyperV, which means you don't have to switch HyperV off to run it as you do with HAXM. It also works via a remote desktop, which HAXM based emulations don't.

If these two advantages aren't enough then the clincher is that it is fast and it has lots of extra, easy to use, features. For example, there is an easy to use control panel that gives you control over the accelerometer, location, network, battery state, camera and SD Card.

You can also use it to take screen shots.

While most of these things can be done using the standard emulator this one makes it easy. In addition you also get the ability to restore a backup by just dragging a zip, copy a local folder to the SD card and use a command line interface.

The fact that the emulator is part of Visual Studio was about the only thing off-putting about trying it and now you don't need to install Visual Studio. You can simply download and install the emulator on its own.

You will need a machine that supports HyperV, but that means most recent machines. If you have run anything else that makes use of HyperV then it should just work. You also don't have to install or configure HyperV to make it work. Simply download and use the installer. When it is all installed try the Nexus 7 emulator first as it has reasonably low resource requirements.

When you have the emulator installed there are still things that can go wrong. In particular the emulator makes use of a USB ADT connection to the IDE you are using. This means if the machine has a lot of USB devices already installed it might not work. I had to remove everything but the USB mouse and keyboard to make the emulator start on one particular machine.

If the emulator starts to load and stalls at 456 MBytes or thereabouts suspect that either your machine doesn't support HyperV or there is a USB clash.

Another problem is that, for some unknown reason, the installer fails to locate the Android SDK. If you run Android Studio and can't see the emulator listed in the drop-down list of devices then you need to edit the registry. Microsoft sccm download. Run Regedit and create or edit the key:

HKEY_LOCAL_MACHINESOFTWAREWow6432NodeAndroid SDK Tools

Notice the spaces in Android SDK Tools. Add the variable Path and set it to the directory where the SDK is stored. When you restart the emulator it should appear in the drop-down list and you should see lots of messages in logcat.

Once you can see the emulator listed as a device you can simply select it as the Run target, either in the dialog box that appears or in the Run Configuration for the app. Essentially, you use the emulator as if it was a real hardware device connected via USB.

You don't get as wide a range of emulator profiles, but those provided - Lollipop to Jellybean - are generally the useful ones. You also only get x86-based emulators, but this is true of HAXM too. The Google ARM emulators are so slow you really have to use a real device.

One final downside is that if you want to use the emulator beyond a 30-day trial period you have to log in with an Azure or Microsoft account. This is still free but you might not like it.
