+ SafetyNet provides services for determining whether a URL has been marked as + a known threat by Google. +
+ ++ The service provides an API your app can use to determine whether a + particular URL has been classified by Google as a known threat. Internally, + SafetyNet implements a client for the Safe Browsing Network Protocol v4 + developed by Google. Both the client code and the v4 network protocol were + designed to preserve users' privacy, as well as keep battery and bandwidth + consumption to a minimum. This API allows you to take full advantage of + Google's Safe Browsing service on Android in the most resource-optimized way, + and without having to implement its network protocol. +
+ ++ This document shows you how to use SafetyNet for checking a URL for threat + types of interest. +
+ ++ By using the Safe Browsing API, you consent to be bound by the Terms of Service. + Please read and understand all applicable terms and policies before accessing + the Safe Browsing API. +
+ ++ To create an API key, complete the following steps: +
+ ++ Your new API key appears; copy and paste this key for future use. +
+ ++ Note: Your API key allows you to perform a URL check + 10,000 times each day. The key, in this instance, should just be a + hexadecimal string, not part of a URL. +
++ If you need more help, check out the Google Developers Console + Help Center. +
+ +
+ Once your key has been whitelisted, you need to add the key to the
+ AndroidManifest.xml file for your app:
+
+<application> + + ... + + <!-- SafetyNet API metadata --> + <meta-data android:name="com.google.android.safetynet.API_KEY" + android:value="your-API-key" /> + + ... + +</application> ++
+ The SafetyNet API is part of Google Play services. To connect to the API, you + need to create an instance of the Google Play services API client. For + details about using the client in your app, see Accessing + Google APIs. Once you have established a connection to Google Play + services, you can use the Google API client classes to connect to the + SafetyNet API. +
+ +
+ To connect to the API, in your activity's onCreate()
+ method, create an instance of Google API Client using
+ GoogleApiClient.Builder. Use the builder to add the SafetyNet API,
+ as shown in the following code example:
+
+protected synchronized void buildGoogleApiClient() {
+ mGoogleApiClient = new GoogleApiClient.Builder(this)
+ .addApi(SafetyNet.API)
+ .addConnectionCallbacks(myMainActivity.this)
+ .build();
+}
+
+
+ Note: You can only call these methods after your app has
+ established a connection to Google Play services by receiving the
+
+ onConnected() callback. For details about listening for a completed
+ client connection, see Accessing
+ Google APIs.
+
+ A URL check allows your app to determine if a URL has been marked as a threat + of interest. Some threat types may not be of interest to your particular + app, and the API allows you to choose which threat types are important for + your needs. You can specify multiple threat types of interest. +
+ ++ The constants in the {@code SafeBrowsingThreat} class contain the + currently-supported threat types: +
+ +
+package com.google.android.gms.safetynet;
+
+public class SafeBrowsingThreat {
+
+ /**
+ * This threat type identifies URLs of pages that are flagged as containing potentially
+ * harmful applications.
+ */
+ public static final int TYPE_POTENTIALLY_HARMFUL_APPLICATION = 4;
+
+ /**
+ * This threat type identifies URLs of pages that are flagged as containing social
+ * engineering threats.
+ */
+ public static final int TYPE_SOCIAL_ENGINEERING = 5;
+}
+
++ When using the API, you must use constants that are not marked as deprecated. + You add threat type constants as arguments to the API. You may add as many + threat type constants as is required for your app. +
+ ++ The API is agnostic to the scheme used, so you can pass the URL with or + without a scheme. For example, either +
+ ++String url = "https://www.google.com"; ++
+ or +
+ ++String url = "www.google.com"; ++
+ is valid. +
+ +
+SafetyNet.SafetyNetApi.lookupUri(mGoogleApiClient, url,
+ SafeBrowsingThreat.TYPE_POTENTIALLY_HARMFUL_APPLICATION,
+ SafeBrowsingThreat.TYPE_SOCIAL_ENGINEERING)
+ .setResultCallback(
+ new ResultCallback<SafetyNetApi.SafeBrowsingResult>() {
+
+ @Override
+ public void onResult(SafetyNetApi.SafeBrowsingResult result) {
+ Status status = result.getStatus();
+ if ((status != null) && status.isSuccess()) {
+ // Indicates communication with the service was successful.
+ // Identify any detected threats.
+ if (result.getDetectedThreats().isEmpty()) {
+
+ }
+ } else {
+ // An error occurred. Let the user proceed without warning.
+ }
+ }
+});
+
++ The result is provided as a list of {@code SafeBrowsingThreat} objects by + calling the {@code SafetyNetApi.SafeBrowsingResult.getDetectedThreats()} + method of the returned {@code SafetyNetApi.SafeBrowsingResult} object. If the + list is empty, no threats were detected; otherwise, calling {@code + SafeBrowsingThreat.getThreatType()} on each element in the list enumerates + the threats that were detected. +
+ ++ Please see the Safe Browsing API Developer's Guide for + suggested warning language. +
