You need a Google\ndeveloper account to create a Google Cloud Console project.\n\nYou can use an existing Google Cloud Console project. Follow\nthe steps below to **add the proper API key restrictions** to your existing\nproject.\n\nSteps\n\nFollow these steps to enable the API:\n\n1. In the Google Cloud Console, go to the **Projects** page. Select an\n existing project or create a new project.\n\n [Go\n to the Projects Page](https://console.cloud.google.com/project)\n\n For more information on creating a Google Cloud Console project, see the\n [Cloud API documentation](https://cloud.google.com/apis/docs/getting-started).\n2. Enable the Android Performance Parameters API on the project you selected.\n\n [Enable\n the API](https://console.cloud.google.com/apis/api/performanceparameters.googleapis.com/overview)\n\n If it has not been enabled, click **ENABLE**.\n3. Select the **Credentials** tab on the left.\n\n4. If the project does not have an existing API key, click **CREATE\n CREDENTIALS** and select **API Key**.\n\n\n **Figure 1.** Create an API key\n5. Copy the API\n key. Later, you will input it into the Unity plugin.\n\n6. Restrict the API key to Android apps only:\n\n 1. You should see a **Key restrictions** section. If not, double-click the API key.\n 2. Under **Application restrictions** , select **Android apps**.\n 3. Click **ADD AN ITEM**.\n 4. Enter your app's package name.\n 5. Enter the SHA-1 certificate fingerprint to\n [authenticate your app](https://developers.google.com/android/guides/client-auth).\n Use the release certificate fingerprint:\n\n ```\n keytool -exportcert -list -v \\\n -alias your-key-name -keystore path-to-production-keystore\n ```\n\n\n **Figure 2.** Restrict the key to Android apps only\n7. Restrict the API key to the Android Performance Parameters API:\n\n 1. Under **API restrictions** , select **Restrict key**.\n 2. Select **Android Performance Parameters API** from the list.\n\n\n **Figure 3.** Restrict the key to the Android Performance Parameters API\n8. Make sure to click **Save** to enable the restrictions.\n\nPrivacy\n\nReview your app's Privacy Policy to ensure that it appropriately reflects that\ndata about devices and usage may be shared with Google. Under Section 3.b the\n[Google APIs Terms of Service](https://developers.google.com/terms), which\ngoverns your use of the Android Performance Parameters APIs, you must:\n\n\"comply with all applicable privacy laws and regulations including those\napplying to PII.
