To find your AirTag on Android, you will need to use the Find My app. This app is designed by Apple and is available on the Google Play Store for Android users. Once you have downloaded the app, follow these steps:
1. Open the Find My app, enter your Apple ID and password, and tap Sign In.
2. Tap on the Items tab at the bottom.
3. If your AirTag is nearby, it should appear in the list of devices. Tap on the AirTag to get more information about it, including its location.
4. You can also tap on the Play Sound button if you are within Bluetooth range to make your AirTag emit a sound.
5. If your AirTag is not nearby, you can put it in Lost Mode, which will alert you when it is found by someone else who uses iPhone, iPad or iPod touch.
Note that in order to use the Find My app, you will need to have an iCloud account and be signed in on your iPhone or iPad that's paired with your AirTag.
