Sample text

5dip" refers to five densityindependent pixels, virtual pixel units that apps can use to express layout dimensions/positions in a screen density-independent way. NOTE: A density-independent pixel is equivalent to one physical pixel on a 160-dpi screen, the baseline density assumed by Android. At run time, Android transparently handles any scaling of the required dip units, based on the actual density of the screen in use. Dip units are converted to screen pixels via equation pixels = dips * (density / 160).

This option lets you store profiling results in a file when starting the AVD via the emulator tool. txt when you press F9. Press F9 again to stop code profiling. Figure 1–10 displays 5554:test_AVD in the titlebar. The 5554 value identifies a console port that you can use to dynamically query and otherwise control the environment of the AVD. NOTE: Android supports up to 16 concurrently executing AVDs. Each AVD is assigned an evennumbered console port number starting with 5554. You can connect to the AVD’s console by specifying telnet localhost console-port.

However, you won’t be able to run those apps via the emulator tool until you create an Android Virtual Device (AVD), a device configuration that represents an Android device. Solution Use the SDK Manager tool to create an AVD. How It Works Run SDK Manager if necessary. Click the Android SDK and AVD Manager dialog box’s Virtual devices entry in the list on the left. You should see the pane shown in Figure 1–8. Figure 1–8. No AVDs are initially installed. Click the New button. Figure 1–9 shows you the resulting Create new Android Virtual Device (AVD) dialog box.
