You can find the timeline of Android evolution by androidacademy here.
At the time of writing (December 2009), there are up to 20,000 applications on Android Market, 62.3% free and 37.7% paid, as reported by AndroidLib. Though Google officials says there are only 16,000 around. Not an easy task to filter out the junk and pick the best.
Those Android applications and games listed in here are what we think are the top/great free applications you should consider using, divided in different categories unless you want a game of serious poker. Click the link in there for the respective application's information, review, author's site before you go and install them via Android market.
If you have not purchased any Android device yet, you can easily compare the specifications of the various Android device in (or coming to) the market on this Android hardware comparison chart.
Well, there are many Android application stores other than the Official Android Market installed on Google Experience Handsets such as HTC Dream G1 and HTC Magic G2.
Reasons for their existance
Some of these complains will be addressed in Android Market for Android 1.6 as Google have announced....but there is the need for 3rd party app stores remains.
Until February, 2011, when Google finally revealed the official Android market web site, one major problem for developers and users is the lack of internet based interface to browse the Official Android market using a computer instead of an Android handset. Since the Android Market application is proprietary not available outside Google Experience Handset, it is not even possbile for prospective users or developers to install it on the Android emulator and browse it there. The only way to look at the Official Android market is to use a Google Experience Handset such as HTC Dream G1 or HTC Magic.
Fortunately, for those without the handset, there are great people out there who had setup web sites which mirrors the Official Android market and allows you to browse the market on your computer. With the increasing number of Android applications and games, currently in the thousands, the web interface is going to be of increasing importance because the small screen on the handset makes it difficult to browse quickly and efficiently.
Here are the unofficial web based mirrors for the Official Android market
With the Official Google Market web site available,which also allow users to select and install applications directly to their Android phone, it remians to be seen whether these unofficial Android market mirror will have any future.
To save you some time to read through and try the thousands of Android applications out there, you can check out the rankings for different applications/games in the sites below.
