Augmented Reality (AR) & Develop AR APP in Android

Augmented reality (AR) is a live, direct or indirect, view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data. It is related to a more general concept called mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of reality. By contrast, virtual reality replaces the real world with a simulated one.Augmentation is conventionally in real-time and in semantic context with environmental elements, such as sports scores on TV during a match. With the help of advanced AR technology (e.g. adding computer vision and object recognition) the information about the surrounding real world of the user becomes interactive and digitally manipulable. Artificial information about the environment and its objects can be overlaid on the real world.

Debugging In Android

Debugging in Android is more easy and faster than any other application development. DDMS is short for Dalvik Debug Monitor Server, which communicates with the low-level services of a device or emulator. Switch to the DDMS perspective now by selecting Window > Open Perspective > DDMS.

The Devices view, located in the left column of the workbench, is where you will see any Android devices available to your computer. This includes both phones attached to your machine and running emulators. Under each device, you will see all the running processes. There are toolbar buttons on the view for launching the debugger on a process, getting information about heaps and threads, stopping processes, and taking screenshots.

The Emulator Control view, also in the left column, lets you do the following:

• Set the status of the voice connection.
• Set the status, speed and latency of the data connection.
• Simulate an incoming call or SMS from a supplied phone number.
• Provide a simulated set of points for the GPS via a latitude/longitude point, or GPX/KML file.
Using the File Explorer view, accessible as a tab at the top-right of the center column, you can browse the file system of a device. For an emulator or a rooted phone, you will have access to the private directories /data and /system. For non-rooted phones, you will only have access to /sdcard.


The debugging perspective will provide in-depth information about your applications. Switch to the debugging perspective by selecting Window -> Open Perspective -> Debug .

The Debug view will show you the running apps being analyzed, and, when stopped on a breakpoint or exception, the call stack of the application as well. The Variables view displays the contents of any local variables at the current breakpoint.
The LogCat view in the lower right hand corner displays all logging output using the android.util.Log class. You can filter based on tags, or different log levels such as debug, information, error, etc.

What Audio Formats Does Android Support?

            Well, there’s support on paper, there’s support in the emulator, and there’s support on the actual devices. On paper, Android supports the following file types (this is subject to change with new releases):
           
              • WAV (PCM uncompressed)
              • AAC (Apple iPod format, unprotected)
              • MP3 (MPEG-3)
              • WMA (Windows media audio)
              • AMR (Speech codec)
              • OGG (Ogg Vorbis)
              • MIDI (Instruments)
       
          In reality, I've found that only the OGG, WAV, and MP3 formats work well in the emulator, and thus those are the only ones that I can recommend for application development. Android’s native audio format appears to be 44.1kHz 16-bit stereo.
           However,since WAV files at that rate are huge, you should just stick to OGG or MP3 files (mono for voice or stereo for music). OGG files seem to work best for short clips like game sound effects. Stay away from unusual rates like 8kHz because the re sampling artifacts make those rates sound terrible. Use 11kHz, 22kHz,or 44.1kHz sampling rates for the best results. Remember that although the phone may have a tiny speaker, many of your users are going to be plugging in headphones (like an iPod), so you want your audio to be high quality.

All Setup Process

Step 1 :
            First install jdk-7-windows-x64.zip. Before installing jdk keep in mind to setup this file in ROOT drive (mainly C drive) . Otherwise You will be faced problem when loading your project.apk file.


Step 2 :
           After setup JDK install installer_r16-windows.zip.


Step 3:
           Check from  your Programs file SDK manager and  AVD manager, there have no packages for android and no AVD because you have not install any platform of android package's or AVD yet


Step 4 :
            For Android's packages and AVD  you have to extract android-sdk.zip into "C:\Program Files (x86)\Android\android-sdk".


Step 5:
           Install MOTODEV_Studio_for_Android_3.1.0_win32_x86_64.zip


Step 6:
           After Installing MOTODEV go to Window>AVD Manager>New (Create Your Own Configuration)


Step 7:
           New Android Project . Write your project name .Choose your target for version of android . Give name of Application name as your Project name or any other name. Then click Finish.


Step 8:
           Then right click on your project Run As> Android Application Using MOTODEV Studio.


Step 9:
           At first time you have to wait 70 seconds(1.10mins)   to 90 seconds (1.30mins) . If it takes more than 2 or 3 mins then you have to ensure your AVD configuration again.


Step 10:
              Then unlock the AVD . Go to menu, you will see your project. Click. Default you will see "Hello World"


Step 11:
              Enjoy the android development
