OPINION: Why in-app billing won't solve Android issues

But developers should be aware of a number of issue before they commit.

1. Cumbersome Check-Out Process : One of the main reasons most Android games are free is Google’s inefficient check-out process.

iPhone has been hugely successful because of its payments process. Users are requested to enter their credit card information when first activating their phone, and majority of users do so. What's more, iTunes store had millions of registered users prior to the iPhone launch. It was a small leap for Apple to get their existing users to download games for their iPhone.

But Android users are only prompted to provide their credit card information after choosing to buy a game. The fact that users need to haul out their credit cards at this stage, combined with a cumbersome purchase flow, lowers the conversion of paid games and applications. Consequently developers have to “sell” their games for free in Google’s Android market.

2. Device Fragmentation: The issue of fragmentation reared its ugly head with Angry Birds’ Android first release and, according to the latest reports, it’s here to stay. And it's not just an issue for developers. Users also need to figure out which flavour will work on their device and can be flustered at the multitude of choices.

In the case of Angry Birds, Rovio developed a separate, lighter version of the game in an attempt to resolve fragmentation issues. Even then, though, users need to figure out which version to install on their device.

As for developers, the plot thickens as Google prepares to separate smartphone and tablet OSs. Rumours say Google will release a mid-way version of Android for smartphones that can run some Android 3.0 (“Honeycomb”) games on phones, which could ultimately result in a further split of the Android OS.

3. Search Limitations: Despite the fact that users can search for content using various “categories”, searching for content in the Android Market can get somewhat confusing. When users search for a specific game or developer in the general search, the results aren’t displayed in the clearest way.

For instance, a simple search for “Angry Birds” is likely to flood your screen with wallpaper collections, unofficial rip-offs, and plain old spam applications. Needless to say, this does not create the best user experience and presents another hurdle for users within the Google Android Market.

Computer Technician Hong Kong – Uninstall an ... - Adsense Course

Windows Update is the main method of updating Windows 7 to keep your PC running smoothly and free from errors. However, not all updates operate as you expect. Learn how to easily view all of the updates installed on your computer and how to uninstall single updates.

Windows Installed UpdatesEvery once in a while, Microsoft releases Service Packs that are primarily a bunch of updates to the Windows operating system that have been packaged up into one download. These Service Packs serve as new version of the operating system so much so that some applications and programs require that your PC be updated to the latest Service Pack before installation.

However, until Service Packs are released, the updates trickle in from Microsoft as individual installations. Although generally tested to be stable, these updates occasionally behave in ways the company did not intend. Luckily, Microsoft built into Windows 7 an easy to use interface for uninstalling individual updates. Computer Service Hong Kong and Computer Technician Hong Kong tells us step by step process to uninstall Windows 7 Updates.

Uninstall Windows 7 UpdatesBegin by logging into Windows 7 with an account that has administrative privileges. Then, click on Start>Control Panel>Programs. Under the Programs and Featureslink, click on the link titled View Installed Updates.You should now be looking at the Uninstall an Update window. You should note a few things here. First, note that each update is automatically categorized by program.

Second, note that the next column indicates to which program the update belongs. Third, the next column indicates the version. Note that few updates use this column so don’t be alarmed if almost all of the updates have this column blank.

Fourth, the next column indicates the publisher of the update. Microsoft often makes use of this column but many other publishers do not. Again, don’t be surprised to see this column mostly blank.

Fifth, the last column indicates when the update was installed. This column is particularly important because it can help you diagnose a malfunctioning computer. If you install an update and your computer starts to act strangely, you can sort the updates found in this windows by date and uninstall the most recent updates to try to fix your PC.You can uninstall any update in this list simply by clicking on it. How the update uninstalls depends on what kind of update it is. For example, Microsoft updates prompt you to ensure you really want to uninstall it.
