SafetyNet Verify Apps API
Stay organized with collections
Save and categorize content based on your preferences.
Note: We recommend using the Play Integrity API to check the status of
Play Protect on a device because it offers several benefits over the SafetyNet
Verify Apps API. Learn more.
The SafetyNet Verify Apps API, a library powered by
Google Play services, lets your app
interact programmatically with the Verify Apps
feature on a device, protecting the device against potentially harmful apps.
If your app handles sensitive user data, such as financial information,
it's important to confirm that the user's device is protected against
malicious apps and doesn't have any apps that could impersonate your
app or perform other malicious actions. If
the device's security doesn't meet the minimum security posture, you can
disable functionality within your own app to reduce the danger to the user.
As part of its continuing commitment to make the Android ecosystem as safe as
possible, Google monitors and profiles the behavior of Android apps. If the
Verify Apps feature detects a potentially dangerous app, all
users who have installed the app are notified and encouraged to promptly
uninstall the app. This process protects the security and privacy of these
users.
The SafetyNet Verify Apps API lets you leverage this feature to protect
your app's data. By using this API, you can determine whether a user's device is
protected by the Verify Apps feature, encourage users who aren't
already using the feature to opt in to its protection, and identify any known
potentially harmful apps that are installed on the device.
Additional terms of service
By accessing or using the SafetyNet APIs, you agree to the Google APIs Terms of
Service and to the following Verify Apps
API Terms of Service.
Please read and understand all applicable terms and policies before accessing
the APIs.
Verify Apps API Terms of Service
The analyses of apps that identify potential harmful apps may yield both false
positives and false negatives. The results (or lack thereof) returned from this
API suite are presented to the best of our understanding.
You acknowledge and understand that the results returned by this SafetyNet API
suite are not guaranteed to be accurate at all times.
Add the SafetyNet API dependency
Before using the Verify Apps API, add the SafetyNet API to your
project. If you are using Android Studio, add this dependency to
your app-level Gradle file. For more information,
see SafetyNet API setup.
Enable app verification
The SafetyNet Verify Apps API provides two methods for enabling the
Verify Apps feature. You can determine whether app
verification is enabled using isVerifyAppsEnabled(), and you can request
enabling of app verification using enableVerifyApps().
The difference between these two methods is that while isVerifyAppsEnabled()
reports the current status of the Verify Apps feature,
enableVerifyApps() explicitly asks the user for consent to use the feature. If
you want your app to just be aware of the feature's status to make a
security-driven decision, your app should call isVerifyAppsEnabled(). However,
if you want to be sure that your app can list potentially harmful installed
apps, you should call enableVerifyApps() instead.
Determine whether app verification is enabled
The asynchronous isVerifyAppsEnabled() method lets your app determine
whether the user is enrolled in the Verify Apps feature. This
method returns a VerifyAppsUserResponse
object, which contains information
regarding all actions that the user has taken related to the Verify Apps
feature, including enabling it.
The following code snippet shows how to create the callback associated with this
method:
Kotlin
SafetyNet.getClient(this)
.isVerifyAppsEnabled
.addOnCompleteListener { task ->
if (task.isSuccessful) {
if (task.result.isVerifyAppsEnabled) {
Log.d("MY_APP_TAG", "The Verify Apps feature is enabled.")
} else {
Log.d("MY_APP_TAG", "The Verify Apps feature is disabled.")
}
} else {
Log.e("MY_APP_TAG", "A general error occurred.")
}
}
Java
SafetyNet.getClient(this)
.isVerifyAppsEnabled()
.addOnCompleteListener(new OnCompleteListener<VerifyAppsUserResponse>() {
@Override
public void onComplete(Task<VerifyAppsUserResponse> task) {
if (task.isSuccessful()) {
VerifyAppsUserResponse result = task.getResult();
if (result.isVerifyAppsEnabled()) {
Log.d("MY_APP_TAG", "The Verify Apps feature is enabled.");
} else {
Log.d("MY_APP_TAG", "The Verify Apps feature is disabled.");
}
} else {
Log.e("MY_APP_TAG", "A general error occurred.");
}
}
});
Request enabling of app verification
The asynchronous enableVerifyApps() method lets your app invoke a dialog
requesting that the user enable the Verify Apps feature. This
method returns a VerifyAppsUserResponse object, which contains information
regarding all actions that the user has taken related to the Verify Apps
feature, including whether they've given consent to enable it.
The following code snippet shows how to create the callback associated with this
method:
Kotlin
SafetyNet.getClient(this)
.enableVerifyApps()
.addOnCompleteListener { task ->
if (task.isSuccessful) {
if (task.result.isVerifyAppsEnabled) {
Log.d("MY_APP_TAG", "The user gave consent to enable the Verify Apps feature.")
} else {
Log.d(
"MY_APP_TAG",
"The user didn't give consent to enable the Verify Apps feature."
)
}
} else {
Log.e("MY_APP_TAG", "A general error occurred.")
}
}
Java
SafetyNet.getClient(this)
.enableVerifyApps()
.addOnCompleteListener(new OnCompleteListener<VerifyAppsUserResponse>() {
@Override
public void onComplete(Task<VerifyAppsUserResponse> task) {
if (task.isSuccessful()) {
VerifyAppsUserResponse result = task.getResult();
if (result.isVerifyAppsEnabled()) {
Log.d("MY_APP_TAG", "The user gave consent " +
"to enable the Verify Apps feature.");
} else {
Log.d("MY_APP_TAG", "The user didn't give consent " +
"to enable the Verify Apps feature.");
}
} else {
Log.e("MY_APP_TAG", "A general error occurred.");
}
}
});
Your app can encounter one or more unusual conditions when using this method:
If the Verify Apps feature is already enabled, the dialog
doesn't appear, and the API behaves as if the user gave consent to enable this
feature.
If the user navigates away from the dialog, the dialog is destroyed, and the
API assumes that the user didn't give consent to enable this feature.
If your app and another app call this method simultaneously, only one dialog
appears, and all apps receive identical return values from the method.
List potentially harmful installed apps
The asynchronous listHarmfulApps() method lets you obtain a list of any
known potentially harmful apps that the user has installed on their device. This
list includes categories for the identified potentially harmful apps so that
your app can take appropriate action.
Note: This method provides only the potentially harmful apps that are
associated with the currently active user or account.
The following code snippet shows how to create the callback associated with this
method:
Kotlin
SafetyNet.getClient(this)
.listHarmfulApps()
.addOnCompleteListener { task ->
Log.d(TAG, "Received listHarmfulApps() result")
if (task.isSuccessful) {
val result = task.result
val scanTimeMs = result.lastScanTimeMs
val appList = result.harmfulAppsList
if (appList?.isNotEmpty() == true) {
Log.e("MY_APP_TAG", "Potentially harmful apps are installed!")
for (harmfulApp in appList) {
Log.e("MY_APP_TAG", "Information about a harmful app:")
Log.e("MY_APP_TAG", "  APK: ${harmfulApp.apkPackageName}")
Log.e("MY_APP_TAG", "  SHA-256: ${harmfulApp.apkSha256}")
// Categories are defined in VerifyAppsConstants.
Log.e("MY_APP_TAG", "  Category: ${harmfulApp.apkCategory}")
}
} else {
Log.d("MY_APP_TAG", "There are no known potentially harmful apps installed.")
}
} else {
Log.d(
"MY_APP_TAG",
"An error occurred. Call isVerifyAppsEnabled() to ensure that the user "
+ "has consented."
)
}
}
Java
SafetyNet.getClient(this)
.listHarmfulApps()
.addOnCompleteListener(new OnCompleteListener<HarmfulAppsResponse>() {
@Override
public void onComplete(Task<HarmfulAppsResponse> task) {
Log.d(TAG, "Received listHarmfulApps() result");
if (task.isSuccessful()) {
HarmfulAppsResponse result = task.getResult();
long scanTimeMs = result.getLastScanTimeMs();
List<HarmfulAppsData> appList = result.getHarmfulAppsList();
if (appList.isEmpty()) {
Log.d("MY_APP_TAG", "There are no known " +
"potentially harmful apps installed.");
} else {
Log.e("MY_APP_TAG",
"Potentially harmful apps are installed!");
for (HarmfulAppsData harmfulApp : appList) {
Log.e("MY_APP_TAG", "Information about a harmful app:");
Log.e("MY_APP_TAG",
"  APK: " + harmfulApp.apkPackageName);
Log.e("MY_APP_TAG",
"  SHA-256: " + harmfulApp.apkSha256);
// Categories are defined in VerifyAppsConstants.
Log.e("MY_APP_TAG",
"  Category: " + harmfulApp.apkCategory);
}
}
} else {
Log.d("MY_APP_TAG", "An error occurred. " +
"Call isVerifyAppsEnabled() to ensure " +
"that the user has consented.");
}
}
});
