Import Android Project

If your android project is already in the workspace folder and you want to use the preceding method to open an existing Android project, you will receive a warning that the project you want to open is already in the working directory. so we have to use another method: import the project.

In the top-left menu of Eclipse, select [file-> Import] to bring up the [import] dialog box. select the [general-> existing projects into workspace] project and press the [next] button to display a new screen. next to the [select root directory] field, click [browse...] on the right. click to select the project. after the selection, press the [finish] button to import the project from the current working environment (workspace) folder to the eclipse environment.

Examples of different SDK versions are stored in the [andriod_sdk/plateforms/Android-version/samples] Directory. Select an example based on the version you want to develop.

After sdk1.5, Android introduces new features that support SDK Simulators of multiple versions. This allows us to modify the attribute settings, to compile and run the target SDK version of these projects.
Right-click the [helloandroid] folder of [navigator] and select the [properties] Option to enable the project Property setting interface.
Select the android tag on the left in the settings screen. The [Project Build target] menu is displayed.
Select an appropriate target version in the menu, and then press OK to end the setting screen. Then, the project is switched to the desired version compiling status.
