Question

I am new to Android. Follow the HelloAndroid Tutorials by use Eclipse. After run HelloAndroid, the AVD \'xian_avd2\' lunched, but stop there, no \" Hello, Android\" display

Answer 1

The problem as I discovered lays in the fact the the project has no appropriate Virtual Device defined for it in the AVD manager.

So the recommended steps in eclipse are:

1. Go to "Project"-> Properties-> Android.
2. On the right pane see what line is checked in the Project build target.
   Remember the target platform number that appears in the selected line.
3. Go to "Windows"-> AVD Manager.
4. Check the list of existing Android Virtual Devices for a device that matches the Platform and API level that you have set for your project (see step #2 above).
5. If there is no line that includes an AVD for your platform (as I suspect), add it using the "New" button.
6. A "Create New Android Virtual Device" window will be opened. set a new device name. in the "Target" selection box choose the right platform for your project.

Enjoy your emulator once again!
