People use android wallet without any complaints. And to be honest I haven't heard of any hack on android wallet and that is a sign that android wallet is not a bad choice for storing your bitcoin.
Surely you can have your wallet in your android device and not lose your funds to hackers, but if it is online, then you have to remember that anything that is connected to the internet is prone to hacking. An online wallet is only good for a small amount of coins, for larger amounts, you have to either use a hardware wallet or set up an airgapped wallet if you have the knowledge to do so, you should also consider extending your seed phrase with a passphrase as an extra layer of security.
