Expo How to create a development build for android and how to create a .apk file?

Ive been reading the documentation and my build seems to succeed, however there is no apk file created. Im not fully sure if im running the right commands. my eas.json file looks like this:

{
  "cli": {
    "version": ">= 5.7.0"
  },
  "build": {
    "development": {
      "developmentClient": true,
      "distribution": "internal",
      "android": {
        "buildType": "apk"
      }
    },
    "preview": {
      "distribution": "internal",
      "ios": {
        "enterpriseProvisioning": "universal"
      }
    },
    "preview2": {
      "android": {
        "gradleCommand": ":app:assembleRelease"
      }
    },
    "preview3": {
      "developmentClient": true
    },
    "production": {}
  },
  "submit": {
    "production": {}
  }
}

I am using android on a simulator and ios on device. I run the following command:

eas build --profile development --platform android

as the documentation says. What am I doing wrong?
