switch-tracker v0.1.0

switch-tracker

Extract switch playtime from the Switch Parental Controls Android app

Nintendo allows switch owners to track their gaming time using the Switch Parental Control app, but no API is available to access that data. This library extracts that data by controlling a developer enabled android device, using the ADB (Android Debug Bridge) command line tool.

See it in action:

This library was tested on a Raspberry Pi and on macOS

Requirements

• Node.js
• ADB

Installation

npm install switch-tracker

Usage

Terminal command

$ switch-tracker

Node.js

import { getSwitchPlayTime } from 'switch-tracker'

async function printPlayTime() {
    const playTime = await getSwitchPlayTime()
    console.log(playTime)
}

printPlayTime()

Example output:

[
  {
    "dateString": "Today",
    "weekday": "Su",
    "minutes": 0,
    "index": 0,
    "date": "2021-01-24"
  },
  {
    "dateString": "Yesterday",
    "weekday": "Sa",
    "minutes": 110,
    "index": 1,
    "date": "2021-01-23"
  },
  {
    "dateString": "22",
    "weekday": "Fr",
    "minutes": 0,
    "index": 2,
    "date": "2021-01-22"
  },
  /* ... */
]

Options

Descriptions:

• pages: Number scrolls down the list of days, determines how many days are parsed
• xmlFile: Temporary XML file path with the android UI information. Note: Probably doesn't need to be changed

Examples:

cli:

$ switch-tracker --pages 6 --xml-file ./android-ui.xml

code:

const playTime = await getSwitchPlayTime({
    pages: 6,
    xmlFile: "./android-ui.xml"
})

Specifications:

Troubleshooting

• Error: Command failed: adb shell uiautomator dump:
  • This is a known transient error, killing the app manually and giving it some time before trying it again should fix it
• Please submit an issue if you run into anything else!

Development

Exiting features and some ideas for new ones:

• extract play time for each day
• cli tool
• handle transient errors
• add option to specify how many days to extract instead of specifying times to scroll
• get games played that day
• use nintendo's api directly instead of controlling an android device (see switchpub)
