Properties
INTEGRITY_API_NOT_AVAILABLE

Integrity API is not available.

Integrity API is not enabled, or the Play Store version might be old. Recommended actions:

  • Make sure that Integrity API is enabled in Google Play Console.
  • Ask the user to update Play Store.

INTEGRITY_APP_NOT_INSTALLED

The calling app is not installed.

Something is wrong (possibly an attack). Non-actionable.

Ask the user to update Play Store.

INTEGRITY_CLIENT_TRANSIENT_ERROR

There was a transient error in the client device.

Introduced in Play Core Java library version 1.1.0 (prior versions returned a token with empty Device Integrity Verdict). If the error persists after a few retries, you should assume that the device has failed integrity checks and act accordingly.

Functions

IntegrityManager_destroy

void IntegrityManager_destroy()

Frees up memory allocated for the Integrity API.

Does nothing if IntegrityManager_init() hasn't been called.

IntegrityManager_init

IntegrityErrorCode IntegrityManager_init(
  JavaVM *jvm,
  jobject android_context
)

Initialize the Play Integrity API, making the other functions available to call.

In case of failure the Play Integrity API is unavailable, and there will be an error in logcat. The most common reason for failure is that the PlayCore AAR is missing or some of its classes/methods weren't retained by ProGuard. See also:IntegrityManager_destroy

Details
Parameters
jvm
The app's single JavaVM, for example from ANativeActivity's "vm" field.
android_context
An Android Context, for example from ANativeActivity's "clazz" field.
Returns
INTEGRITY_NO_ERROR if initialization succeeded, or an error if failed.

IntegrityManager_requestIntegrityToken

IntegrityErrorCode IntegrityManager_requestIntegrityToken(
  IntegrityTokenRequest *request,
  IntegrityTokenResponse **out_response
)

Starts an asynchronous operation to obtain a Play Integrity API token.

For an ongoing asynchronous operation, use IntegrityTokenResponse_getStatus() to poll for the status of the IntegrityTokenResponse. When the status reaches INTEGRITY_RESPONSE_COMPLETED with INTEGRITY_NO_ERROR, use IntegrityTokenResponse_getToken() to acquire the resulting token.

See also: IntegrityTokenResponse_destroy

Details
Parameters
request
The request containing the nonce.
out_response
An out parameter for receiving the result.
Returns
INTEGRITY_NO_ERROR if the request started successfully, corresponding error if failed.

IntegrityTokenRequest_create

IntegrityErrorCode IntegrityTokenRequest_create(
  IntegrityTokenRequest **out_request
)

Creates a new IntegrityTokenRequest opaque struct.

See also: IntegrityTokenRequest_destroy

Details
Parameters
out_request
An out parameter for receiving the result.
Returns
An IntegrityErrorCode, which if not INTEGRITY_NO_ERROR indicates that the out parameter shouldn't be used.

IntegrityTokenRequest_destroy

void IntegrityTokenRequest_destroy(
  IntegrityTokenRequest *request
)

Releases the specified IntegrityTokenRequest and any references it holds.

Details
Parameters
request
The request to free.

IntegrityTokenRequest_setCloudProjectNumber

IntegrityErrorCode IntegrityTokenRequest_setCloudProjectNumber(
  IntegrityTokenRequest *request,
  int64_t cloudProjectNumber
)

Sets the cloud project number to link to the integrity token.

This field is required for apps exclusively distributed outside of Google Play and SDKs. For apps distributed on Google Play, the cloud project number is configured in the Play Console and need not be set on the request.

Cloud project number can be found in Project info in your Google Cloud Console for the cloud project where Play Integrity API is enabled.

Calls to decrypt the token on Google's server must be authenticated using the cloud account that was linked to the token in this request.

Details
Parameters
request
The IntegrityTokenRequest to set cloudProjectNumber.
cloudProjectNumber
The cloudProjectNumber for the request.
Returns
An IntegrityErrorCode, which if not INTEGRITY_NO_ERROR indicates that this operation has failed.

IntegrityTokenRequest_setNonce

IntegrityErrorCode IntegrityTokenRequest_setNonce(
  IntegrityTokenRequest *request,
  const char *nonce
)

Sets the nonce in an IntegrityTokenRequest with a given string.

It must be base64 encoded in web-safe no-wrap form.

See https://developer.android.com/google/play/integrity/verdict#nonce for details about the nonce requirements and recommendations.

Details
Parameters
request
The IntegrityTokenRequest for which to set token.
nonce
The nonce for the request.
Returns
An IntegrityErrorCode, which if not INTEGRITY_NO_ERROR indicates that this operation has failed.

IntegrityTokenResponse_destroy

void IntegrityTokenResponse_destroy(
  IntegrityTokenResponse *response
)

Releases the specified IntegrityTokenResponse and any references it holds.

Details
Parameters
response
The response to free.

IntegrityTokenResponse_getStatus

IntegrityErrorCode IntegrityTokenResponse_getStatus(
  IntegrityTokenResponse *response,
  IntegrityResponseStatus *out_status
)

Gets the status of an ongoing IntegrityManager_requestIntegrityToken() asynchronous operation.

This function can be used to poll for the completion of a call to IntegrityManager_requestIntegrityToken(). This function does not make any JNI calls and can be called every frame.

Details
Parameters
response
The IntegrityTokenResponse for which to get status.
out_status
An out parameter for receiving the IntegrityResponseStatus.
Returns
An IntegrityErrorCode indicating the error associated with the given IntegrityTokenResponse.

IntegrityTokenResponse_getToken

const char * IntegrityTokenResponse_getToken(
  IntegrityTokenResponse *response
)

Gets the token retrieved by a successful IntegrityManager_requestIntegrityToken() asynchronous operation, returns null pointer otherwise.

The JSON payload is signed and encrypted as a nested JWT, that is JWE of JWS.

JWE uses A256KW as a key wrapping algorithm and A256GCM as a content encryption algorithm. JWS uses ES256 as a signing algorithm.

All decryption and verification should be done within a secure server environment. Do not decrypt or verify the received token from within the client app. In particular, never expose any decryption keys to the client app.

See https://developer.android.com/google/play/integrity/verdict#token-format.

The string returned here is owned by the API, and the pointer will be valid until the corresponding IntegrityTokenResponse is freed by calling IntegrityTokenResponse_destroy().

Details
Parameters
response
The IntegrityTokenResponse specifying the asynchronous operation.
Returns
A token which contains the response for the integrity related enquiries.
