+   
+  Open SDK Manager: First, locate and open the SDK Manager. You can find it in the tools directory of your Android SDK installation.
+    
+	Launch SDK Manager: Run the sdkmanager command in your terminal or command prompt. Navigate to the tools/bin directory within your Android SDK installation and use the following command:
+
+	`sdkmanager --list`
+
+	This command will list all available packages and their versions.
+	 
+	Select and Install Previous Android Versions: Once you see the list of available packages, you can find the specific version you want to install. For instance, to install Android 9.0 (API level 28):
+
+	`sdkmanager "platforms;android-28"`
+
+	Replace "platforms;android-28" with the appropriate package name of the desired Android version. This command will download and install Android 9.0 (API level 28).
+	
+	 
+	Additional Components: If you need additional components such as system images or tools for a specific version, you can install them using similar commands:
+
+
+	`sdkmanager "system-images;android-28;google_apis;x86_64"`
+
+	Again, adjust the package name to match the specific version and components you require.
