Install electrum on your android phone. You can create a watch only wallet using your PC wallet's xpub. A watch only wallet lets you see transactions, addresses and balance but not spend your coins. It's like a readonly view of your PC's wallet.
To create the watch-only wallet on your phone start with step 3 under "deterministic watch only wallet" in
this guide. The screenshots are for the PC version but the steps are the same on android. In step 5 entering mpk you can simply use the camera on your phone to take a pic of the PC wallet's MPK QR code which you can find via wallet menu > information.
If you're using a 2fa wallet on your PC (addresses start with 3) then the steps are a little different. In that case try
this guide here to create a watch only version on your mobile. Once again the screenshots vary but the basic idea is the same.
