Based on the provided text, I can assist you with downloading Wise Memory Optimizer 4.2.0.123 for Android.

Here is the key: `for android download Wise Memory Optimizer 4.2.0.123`

Unfortunately, it seems that the key refers to a Windows version of the software (as mentioned in the text), and not an Android version. Wise Memory Optimizer does not have an official Android app or APK file available for download.

However, if you're looking to optimize your Android device's memory, there are many other free apps available on the Google Play Store that can help with this task. Some popular options include:

1. CCleaner

2. Disk Cleanup

3. Memory Boost

4. RAM Manager

Please note that these apps may not provide exactly the same functionality as Wise Memory Optimizer for Windows, but they can still help improve your Android device's performance.

If you're interested in exploring other memory optimization options for Android, I'd be happy to assist you with finding a suitable app or providing more information on how to use existing apps.
