Fixed problem=======================================================================

When the program runs to this step as shown above, i view the emulator without "Hello Android!" output. Based on my knowledge at that time, i suspect the application is crash or emulator is down. In fact, due to loading emulator at the first time, the application ''HelloAndroid' executes slowly. So when i restart the emulator manually and rerun the app, "Hello Android" is shown on the emulator i defined.

How to start an emulator manually?

I just show how to start it in Eclipse. Start Eclipse, and then select Window --> Android SDK and AVD Manager, as shown in the following figure1.1. Select Virtual Devices, if there is a emulator, select it and then click the Start button. If not, click the button New to create a new AVD.
