为什么Android应用程序限制不适用于Google Directions API？

Question

So apparently android app restriction doesn't work when I call google directions API from my android app I still get the Your IP is restricted etc.

So I apparently googled and read somewhere that Android app restriction is valid only for Google Maps Android API v2 and Google Maps Places for Android.

The question is why?

Answer 1

I think there are also restrictions in google direction API. You can pass your API key in the URL(parameter is key ). For example

https://maps.googleapis.com/maps/api/directions/json?origin=75+9th+Ave+New+York,+NY&destination=MetLife+Stadium+1+MetLife+Stadium+Dr+East+Rutherford,+NJ+07073&key=YOUR_API_KEY

Answer 2

Directions API is a web service and it is supposed to be called from your backend server, not from mobile device directly. The API keys for web services support only IP address restriction. So, in order to protect an API key that you are going to use with web service requests you should create an intermediate server that will send requests to Google and pass responses back to your Android app. To protect an API key you should use an IP address of your intermediate server.

There is a feature request in the Google issue tracker to add services similar to Maps JavaScript API v3 directly in Maps Android API v2:

Hope this addresses your doubt.
