I have written the following GetPDFPreview() method. It open a PDF file, create a thumbnail (using PdfDocument class) and returns the result.

The auto-flipping ViewFlipper is useful for status panels or other situations where you have a lot of information to display, but not much room. The caveat is that, since it automatically flips between views, expecting users to interact with individual views is dicey, because the view might switch away partway through their interaction.

Note Unlike view state, information passed through the query string is clearly visible and unencrypted.

Each controller must turn into a method (sometimes several methods) on the sequence diagram. Tip If a controller is missed, the result is that some functionality will almost inevitably be missed in the code. In some cases, your controllers might be real control classes, which really doesn t change much because those classes have methods, too. Being more coarse-grained on the robustness diagram is OK, but you need to get atomic on the sequence diagram. In the example, the programmer got atomic on the robustness diagram but reverted to molecular on the sequence diagram.

The next program presents a list of entries. When the user chooses an item by clicking the appropriate item in the list, the user is forwarded to a new page. This page displays the received ID number. This provides a quick and simple query string test with two pages. In a sophisticated application, you would want to combine some of the data control features that are described later in Part 3 of this book. The first page provides a list of items, a check box, and a submission button (see Figure 9-6).

Figure 9-6. A query string sender Here s the code for the first page:

Android offers a wide range of available units of measure for dimensions. The most popular has been the pixel (px), because it is easy to wrap your head around the concept. After all, each Android device will have a screen with a certain number of pixels in each direction. However, pixels start to become troublesome as screen density changes. As the number of pixels in a given screen size increases, the pixels effectively shrink. A 32-pixel icon on a traditional Android device might be finger-friendly, but on a high-density device (say, WVGA in a mobile phone form factor), 32 pixels may be a bit small for use with a finger. If you have something intrinsically scalable (e.g., a Button) where you had been specifying a size in pixels, you might consider switching to using millimeters (mm) or inches (in) as the unit of measure 10 millimeters are 10 millimeters, regardless of the screen resolution or the screen size. This way, you can ensure that your widget is sized to be finger-friendly, regardless of the number of pixels that might take.
