The Google Maps API is one of the most powerful tools that developers can use to integrate maps, geolocation, and location-based services into their apps. However, if you're working with the Google Directions API on Android, you may encounter an error that says "This API project is not authorized to use this API." This error can be frustrating, especially if you're new to the API, but it's usually easy to fix.
In this article, we'll take a look at why this error occurs, some common causes of the error, and how to fix it using examples from Google Directions API.
Why does this error occur?
The Google Directions API is one of the many APIs in the Google Maps Platform. When you want to use the API in your app, you need to create a project in the Google Cloud Console, get an API key, and enable the API. This process allows you to use the API on your app.
However, if you encounter the error message "This API project is not authorized to use this API," it's usually because your API key does not have the proper permissions or the API is not enabled for your project.
Common causes of the error
There are several common causes of the "This API project is not authorized to use this API" error, including:
-
Incorrect API key: Ensure that your API key is correct. If you have re-generated your API key, make sure you're using the new key.
-
API not enabled: Ensure that the Google Directions API is enabled for your project. To enable the API, go to the Google Cloud Console, select your project, and then click on "APIs & Services" > "Library". Search for "Directions API" and click on "Enable".
-
Incorrect billing information: The Google Maps Platform requires a billing account to use some of its APIs. Ensure that you have a billing account set up and can access it.
-
Quota limit exceeded: Each API has its own usage limit, and you might run into the "This API project is not authorized to use this API" error if you exceed your usage limit. Check your usage dashboard to see if this is the case.
How to fix the error using Android code examples
The following code example shows how to use the Google Directions API on Android. This code assumes that you have set up your API key and have enabled the API for your project.
If you're still encountering the error, try the following steps:
-
Check your API key: Ensure that you're using the correct API key by re-generating your key and updating it in your project. You can check if your API key is correct by using the Google Maps Platform API checker.
-
Enable the API: Ensure that the Google Directions API is enabled for your project. If it's not, enable it by going to the Google Cloud Console, selecting your project, and then clicking on "APIs & Services" > "Library". Search for "Directions API" and click on "Enable".
-
Add Android app restrictions to your API key: In some cases, you may need to add an Android app restriction to your API key. To do this, go to the Google Cloud Console, select your project, and then click on "APIs & Services" > "Credentials". Select your API key, and then click on "Edit". Under "API restrictions", select "Android app" and enter your package name and SHA-1 fingerprint.
-
Check your billing information: Ensure that you have a billing account set up and can access it. If you have exceeded your quota limit, you may need to upgrade your account or request more usage.
Once you have tried these steps, you should be able to use the Google Directions API on your Android app without experiencing the "This API project is not authorized to use this API" error.
