  4. 4. WHAT IS THE OPEN HANDSET ALLIANCE (OHA)  Its a consortium of 86 H/W ,S/W and telecommunications companies.
  5. 5. WHAT IS THE OPEN HANDSET ALLIANCE (OHA)  Devoted to advancing open standards for mobile devices.  Develop technologies that will significantly lower the cost of developing and distributing mobile devices and services.  Write apps to run on mobile phones.

  6. 6. VERSIONS OF ANDROID VERSION CODENAME API_LEVEL 1.0 Base 1 1.5 Cupcake 3 1.6 Donut 4 2.1 Eclair 7 2.2 Froyo 8 2.3 - 2.3.2 Gingerbread 9 2.3.3 - 2.3.7 10 3.1 Honeycomb 12 3.2 13 4.0.3 - 4.0.4 Ice Cream Sandwich 15 4.1 Jelly Bean 16NOTE:- API Level is an integer value that uniquely identifies the frameworkAPI revision offered by a version of the Android platform.
  7. 7. PROBLEM’S WITH ANDROID SYSTEM 1: Software fragmentation:-  Simply put, there are too many versions of the Android operating system in circulation. This means that developers can’t just focus on the most recent versions of the OS.  Not everyone has upgraded. It’s not easy for users to upgrade their operating systems, and carriers have little incentive to do so.  For example, we bought an Android phone in February 2011 that came equipped with Android 2.1. Version 2.2 had been released way back in July of 2010!
  8. 8. PROBLEM’S WITH ANDROID SYSTEM 2: Hardware fragmentation:-  User of android is usually faces the Hardware problems which will affected the Throughput speed.  For example Button A on Handset 1 does Function X. The problem? Button A on Handset 2 does Function Y. Here’s a look at the variety of button configurations. So obviously, you can’t design an app that relies on Button A to do the same thing for everyone. Users may grow frustrated and give up on an app that doesn’t perform intuitively.
  9. 9. PROBLEM’S WITH ANDROID SYSTEM 3:Security Issues:-  Lack of governance in the Android market has led to a proliferation of malware programs that can masquerade as trusted apps.  The openness of Android has made it susceptible to attack. To make matters worse, unlike traditional open source software.  Fragmentation on Android makes it difficult to roll out fixes. It’s hard to keep customers happy and retain trust when security problems can’t be fixed quickly.
  10. 10. PROBLEM’S WITH ANDROID SYSTEM 4:Market Research Cost:-  As mentioned, understanding your customer is the key to getting an Android app right. This, of course, requires lots of research into how customers use the software and hardware on their phones. And, yes, that takes time and can therefore be an expensive endeavor for developers to undertake.
  11. 11. PROBLEM’S WITH ANDROID SYSTEM5:Some other Problems:- CPU typically run 500-600 Mhz.Ram available to an App may only be few Megabytes.Disk (flash) access is very Slow.Network access may be slow or (very) intermittent.Sometimes gives illusion that Apps is running while the appswas closed.Too much Google dependent.
  12. 12. ANDROID TECHNOLOGIESIntroducing several technologies like:-Amazing Photo Sphere- Up, down and all around you, it’s like no camerawe’ve ever seen. With Android 4.2, snap pictures in every direction that cometogether into incredible, immersive photo spheres that put you right inside thescene.We can also View our photo spheres right on your phone, share them onGoogle+ with your friends and family, or even add them to Google Maps forthe world to see.
