I tried project-> properties-> android->, but here it shows me only one checkbox for API level 8. Please call me, what should I do ??
Course
Off shows only one checkbox for API level 8, because you may have only downloaded the SDK Platform Android 2.2, API 8 and API level 3 means that you want to run the application on Android 1.5. Therefore, you also need to download the SDK Platform Android 1.5, API 3
To download this, open the Android SDK and AVD Manager and click Available Packages . Here you can find the SDK Platform Android 1.5, API 3 inside the Android Repository , and after downloading it, you need to create a new Android Virtual Device by selecting Target as Android 1.5 API Level 3 . After that, you can change the API level 8 to 3
