Logging into icloud from Android so I can locate my iphone

An Android browser that can access the "desktop site " version of iCloud.com is what you need.

An internet search for android browser ask for desktop site should get you started.

You can just go to any other device use the internet and go on iCloud.com then go on Find my iPhone and you will be good.

Firstly, you would need to 'request Desktop site' as LCAllen has indicated. Even then there's a strong likelihood that it won't work - the site contains programming that mobile devices can't handle.

Even if you do get it, you can't just sign in with your password. As you are using a non-Apple app you are now required to use an 'app-specific' password in place of your normal iCloud password. In order to do this you need to set up two-factor authentication for your Apple ID, and for this you need to have either a Mac running el Capitan or above, or an iOS device running iOS9 or above.

Using app-specific passwords - Apple Support

If you are unable to set up two-factor authentication you should set up 2-step verification and use that to create an app-specific password (see link below) . Then go to https://appleid.apple.com , select 'Password and Security'; click 'Generate an App-Specific Password' and follow the instructions. Once you have the password, copy it and paste it into the password field in the application instead of your usual iCloud password. You should also keep a note of it (though you can generate a new one if required).

Two-step verification for Apple ID - Apple Support

You will need to nominate a 'trusted device': any phone capable of receiving SMS messages. There will be a 2-day wait before you can complete the process.

(A particular caveat (about 2-step only) - you will be issued with a 'Recovery Key' in case you lose your 'trusted device'. Make sure to write this down and keep it in a safe place; if you lose both it and your trusted device you will be permanently locked out of your ID. You'd be surprised at the number of people who've posted here that they've got themselves into just that position.)

You would do better to do all this from a Desktop computer but you will still likely need the app-specific password.
