How To find an appid in IOS or packageId in Android

IOS

Finding appid for an ios app

Search for an app on itunes store. Lets take the example of clash of clans.



The area marked on red is the app's appid

ANDROID

Finding packageId for an android app

Search for an app on playstore. Lets take the example of clash of clans.



The area marked on red is the app's packageId

Advanced Options

getAppstoreAppVersion(identifier, options);

params:

  • identifier is the app package id like com.example.app

  • options contains values which can affect the result obtained from the store

    • jquerySelector [Android] is the dom element identifier (much like jquery selector) for playstore app page. Currently to get the appversion from the page we do load https://play.google.com/store/apps/details?id=<app package id> and parse $('body > [itemprop="softwareVersion"]') but you can optionally pass in a custom selector if you want. This is useful if dom structure of the app store page changes in the future.

    • typeOfId [iOS] (default is id) It can be either id or bundleId. If the typeOfId is id you need to pass identifier as appid and if typeOfId is bundleId you need to pass bundleIdentifier to identifier. It is basically, the query parameter for https://itunes.apple.com/lookup?${typeOfId}=${identifier}.
      Currently to get the ios version number from app store we hit the url https://itunes.apple.com/lookup?id=<app id> by default.
      or we can also hit
      https://itunes.apple.com/lookup?bundleId=<app bundle id> if we pass typeOfId as bundleId.
      When we hit the above said urls we get json with all the info of the app.

    • country [iOS] (default is us) The two-letter country code for the store you want to search. The search uses the default store front for the specified country.

Example

const storeSpecificId = Platform.OS === 'ios'
    ? '529479190'
    : 'com.supercell.clashofclans'

getAppstoreAppVersion(storeSpecificId, {
    jquerySelector: '[itemprop=\'softwareVersion\']',
    typeOfId: 'id',
    country: 'de'
})
