The Android Market has a huge selection of free apps, but there are times when it s worth it to buy an app. You can use Google Checkout or direct phone carrier billing, where available. Currently, T-Mobile is the only supported carrier for direct billing (and for US dollar transactions only), but as Android gains momentum, this is sure to change. Google Checkout is an online payment-processing system. Register for a Google Checkout account by going to http://checkout.google.com and using the same Google account you use as the main account for your phone. You can enter your credit card information and Google will store it. Register in advance to avoid the hassle of entering credit card info on a phone keyboard. You can purchase apps in most foreign currencies using Google Checkout and your credit card (Figure 14 6). Google will give you an estimate of what the price is in US dollars. However, your credit card may charge you a fee for currency conversion or use a different exchange rate, and that won t be reflected on the bill.

Other than payment processing, the basic steps to downloading an app are the same. Go to the Android Market, navigate to the details page, and click the Install button at the bottom of the screen. Android will confirm that you want to download the app, and it will also show you specific information (Figure 14 7) about what the app has permission to do with your phone. In most cases, the uses are quite legitimate, but you should read them carefully to make sure a word puzzle game doesn t have access to dial your phone, for example.

If everything looks good, click the OK button. Your download will start, and you ll see a progress bar in the Android Market and notice in your notification bar that a download is in progress. The notice will change once the download is complete. There s no need to keep using the Android Market app while you re downloading. The download will continue in the background.
Installing Apps
In most cases, downloading the app installs it automatically. If there are any widgets included with the app, you ll need to long-click the Home screen to install them. If there are additional steps, the developer should provide instructions. In the case of some paid apps, you may have two downloads. The first is a trial version, and the second is a separate key that doesn t actually do anything other than unlock the full features from the first app. NOTE: Android 2.2 (Froyo) allows developers to give you the option to install apps on your SD card instead of the phone s hard disk. This can potentially save some space. However, it is up to the developer to allow the option in their app.
CHAPTER 14: The Android Market
Uninstalling Apps
There are two basic ways to uninstall an app. The more complicated method is to go to the Home screen, press the Menu button, and then click Applications Manage applications. Click the app you want to remove, and then click Uninstall. The second, much easier method is to find your app in the Android Market, navigate to the detail page for that app, and click the Uninstall button. If you paid for the app, you ll see an Uninstall & refund button, as shown in Figure 14 8. You have 24 hours after a purchase to return it for a refund. However, you must do this through the Android Market.
Figure 14 8. Uninstalling
You ll see a warning window telling you that you re about to uninstall an app. You ll also be told whether or not you can install the app again at no charge. In the case of paid apps, not only must you pay for it again (since you re being refunded), you cannot return it twice for a refund. Android also collects data on why you chose to uninstall an app. Select a reason or I d rather not say, and then OK.
