PlayIntegrity API Calls: How to handle GoogleServerUnavailable Error

I am developing an Android security app and have decided to implement the PlayIntegrity API as an alternative to SafetyNet API. I have already completed the necessary setup steps such as enabling the Play and Cloud console, however, I am encountering an issue where I am getting an error 'GOOGLE SERVER UNAVAILABLE' when trying to obtain a token. Can anyone provide any insight into why this might be happening and possible solutions? Any help would be greatly appreciated.
Please see below code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// playIntegritySetup.lol();
getToken();
}
private void getToken() {
String nonce = Base64.encodeToString(generateNonce(50).getBytes(), Base64.URL_SAFE | Base64.NO_WRAP | Base64.NO_PADDING);
// Create an instance of a manager.
IntegrityManager integrityManager = IntegrityManagerFactory.create(getApplicationContext());
// Request the integrity token by providing a nonce.
Task<IntegrityTokenResponse> integrityTokenResponse = integrityManager.requestIntegrityToken(
IntegrityTokenRequest.builder()
.setNonce(nonce)
.build());
integrityTokenResponse.addOnSuccessListener(new OnSuccessListener<IntegrityTokenResponse>() {
#Override
public void onSuccess(IntegrityTokenResponse integrityTokenResponse) {
String integrityToken = integrityTokenResponse.token();
SplashActivity.this.doIntegrityCheck(integrityToken);
Log.e("Integrity Token", "integrity token from the app" + integrityToken);
}
});
integrityTokenResponse.addOnFailureListener(e -> showErrorDialog("Error getting token from Google. Google said: " + getErrorText(e)));
}
private void doIntegrityCheck(String token) {
AtomicBoolean hasError = new AtomicBoolean(false);
Observable.fromCallable(() -> {
OkHttpClient okHttpClient = new OkHttpClient();
Response response = okHttpClient.newCall(new Request.Builder().url("money control url" + "token from backend server" + token).build()).execute();
Log.e("Token", "token from the app" + token);
if (!response.isSuccessful()) {
hasError.set(true);
return "Api request error. Code: " + response.code();
}
ResponseBody responseBody = response.body();
if (responseBody == null) {
hasError.set(true);
return "Api request error. Empty response";
}
JSONObject responseJson = new JSONObject(responseBody.string());
if (responseJson.has("error")) {
hasError.set(true);
return "Api request error: " + responseJson.getString("error");
}
if (!responseJson.has("deviceIntegrity")) {
hasError.set(true);
}
return responseJson.getJSONObject("deviceIntegrity").toString();
}) // Execute in IO thread, i.e. background thread.
.subscribeOn(Schedulers.io())
// report or post the result to main thread.
.observeOn(AndroidSchedulers.mainThread())
// execute this RxJava
.subscribe(new Observer<String>() {
#Override
public void onSubscribe(Disposable d) {
}
#Override
public void onNext(String result) {
if (hasError.get()) {
if (result.contains("MEETS_DEVICE_INTEGRITY") && result.contains("MEETS_BASIC_INTEGRITY")) {
//Here goes my other code
}
}
}
#Override

});
}
private String getErrorText(Exception e) {

if (msg == null) {

}

private String generateNonce(int length) {

I ran into the same problem and I found a solution for this.
You need to specify cloudProjectNumber() when you are working on outside of Google Play, which can be found in google cloud console.
Quote from the doc:
Important: In order to receive and decrypt Integrity API responses,
apps not available on Google Play need to include their Cloud project
number in their requests. You can find this in Project info in the
Google Cloud Console.
So the code should be like this:
IntegrityTokenRequest.builder()
.setNonce(nonce)
.cloudProjectNumber(100004676) // your cloud project number here for dev build
.build());

Unable to connect to the Samsung Health using Health Data Store

I am trying to connect my application with Samsung health, but i am unable to connect to the HealthDataStore.
I have enabled sHealth in developer mode.
I have added permission for the meta data.
HealthDataStore mStore = new HealthDataStore(DashboardListActivity.this,mConnectionListener);
mStore.connectService();
private final HealthDataStore.ConnectionListener mConnectionListener = new HealthDataStore.ConnectionListener() {
#Override
public void onConnected() {
Log.d(TAG, "Health data service is connected.");
/*HealthPermissionManager pmsManager = new HealthPermissionManager(mStore);
Map<HealthPermissionManager.PermissionKey, Boolean> resultMap = pmsManager.isPermissionAcquired(mKeySet);
if (resultMap.containsValue(Boolean.FALSE)) {
// Request the permission for reading step counts if it is not acquired
pmsManager.requestPermissions(mKeySet, mActivity).setResultListener(mPermissionListener);
} else {
// Get the current step count and display it
// ...
HealthDataResolver.AggregateRequest request = (HealthDataResolver.AggregateRequest) new HealthDataResolver.AggregateRequest.Builder()
.setDataType(HealthConstants.Exercise.HEALTH_DATA_TYPE);
}*/
}
#Override
public void onConnectionFailed(HealthConnectionErrorResult healthConnectionErrorResult) {
Log.d(TAG, "Health data service is not available.");
//showConnectionFailureDialog(healthConnectionErrorResult);
}
#Override
public void onDisconnected() {
Log.d(TAG, "Health data service is not Disconnected.");
}
};
I am always getting the onConnectionfailed, its not hitting the connection success.

Send message with Telegram API and store session (NOT with bot API)

I want to implement a very simple Java Telegram Client, which is capable of sending and receiving messages and store the sessions across multiple starts. I already managed to authenticate and receive messages
api = new TelegramApi(apiState, new AppInfo(API_ID, "console", "1", "1", "en"), new ApiCallback() {
#Override
public void onAuthCancelled(TelegramApi api) {
Log.d(TAG, "-----------------CANCELLED----------------");
Log.d(TAG, api.getApiContext().toString());
}
#Override
public void onUpdatesInvalidated(TelegramApi api) {
Log.d(TAG, "-----------------INVALIDATED----------------");
Log.d(TAG, api.getApiContext().toString());
}
#Override
public void onUpdate(TLAbsUpdates tlAbsUpdates) {
Log.d(TAG, "-----------------UPDATE----------------");
Log.d(TAG, tlAbsUpdates.toString());
if (tlAbsUpdates instanceof TLUpdateShortMessage) {
Log.d(TAG, "-----------------UPDATE CHAT MESSAGE----------------");
int senderId = ((TLUpdateShortMessage) tlAbsUpdates).getUserId();
Log.d(TAG, "Message from " + senderId);
String message = ((TLUpdateShortMessage) tlAbsUpdates).getMessage();
Log.d(TAG, message);
activity.appendMessage(TAG, message);
}
}
});
api.switchToDc(2);
TLConfig config = null;
try {
config = api.doRpcCallNonAuth(new TLRequestHelpGetConfig());
} catch (TimeoutException | IOException e) {
e.printStackTrace();
}
apiState.updateSettings(config);
However, I struggle to send messages to another user. For the beginning, it would be enough if I could send a message back to the user, who sent me a message before (by retrieving the senderId, as you can see in the onUpdate method before). However, if someone could also help me with retrieving the ids of my saved contacts, it would be perfect.
Furthermore, I want to store the sessions accross multiple startups, since I get a FLOOD_WAIT error (420), if I test my code to often.
For this I used https://github.com/rubenlagus/TelegramApi/blob/51713e9b6eb9e0ae0d4bbbe3d4deffff9b7f01e4/src/main/java/org/telegram/bot/kernel/engine/MemoryApiState.java and its used classes (e.g. TLPersistence), which stores and loads the ApiState. However, apparently it does not store the signin status, since I always have to authenticate my number every time I update the code.
By the way, I am using Api layer 66 (https://github.com/rubenlagus/TelegramApi/releases).
UPDATE 1:
Problems with sending messages solved myself:
private void sendMessageToUser(int userId, String message) {
TLInputPeerUser peer = new TLInputPeerUser();
peer.setUserId(userId);
TLRequestMessagesSendMessage messageRequest = new TLRequestMessagesSendMessage();
messageRequest.setFlags(0);
messageRequest.setPeer(peer);
messageRequest.setRandomId(new SecureRandom().nextLong());
messageRequest.setMessage(message);
api.doRpcCallNonAuth(messageRequest, 1500, new RpcCallback<TLAbsUpdates>() {
#Override
public void onResult(TLAbsUpdates tlAbsUpdates) {
Log.d(TAG, "-----------------------MESSAGE SENT-----------------------");
}
#Override
public void onError(int i, String s) {
Log.d(TAG, "-----------------------MESSAGE SENT ERROR-----------------------");
Log.d(TAG, String.valueOf(i));
if(s != null) {
Log.d(TAG, s);
}
}
});
}
However, now I am stuck at finding the userIds of my contacts.
After first update this is left:
Saving the session state (and signin state)
Find userIds of contacts
Update 2:
I managed to fetch the users, with which there are already dialogs. This is enough for my use case, however, loading all contacts would be perfect. This is how to load users from existing dialogs:
private int getUserId(String phone) throws InterruptedException {
TLRequestMessagesGetDialogs dialogs = new TLRequestMessagesGetDialogs();
dialogs.setOffsetId(0);
dialogs.setLimit(20);
dialogs.setOffsetPeer(new TLInputPeerUser());
CountDownLatch latch = new CountDownLatch(1);
api.doRpcCallNonAuth(dialogs, 1500, new RpcCallback<TLAbsDialogs>() {
#Override
public void onResult(TLAbsDialogs tlAbsDialogs) {
Log.d(TAG, "----------------------getUsers--------------------");
for(TLAbsUser absUser : ((TLDialogs) tlAbsDialogs).getUsers()) {
users.add((TLUser) absUser);
}
latch.countDown();
}
#Override
public void onError(int i, String s) {
Log.d(TAG, "----------------------getUsers ERROR--------------------");
latch.countDown();
}
});
latch.await();
for(TLUser user : users) {
if(user.getPhone().equals(phone)) {
return user.getId();
}
}
return 0;
}
After second update this is left:
Saving the session state (and signin state)
Get user ids from contacts instead of dialogs

how to register azure mobile service .net backend custom api

I have created a .NET backend Mobile Service on Windows Azure using the code sample provided on the website article.
Now I am trying to register a user with android client but I can't.
My backend registration control looks like below;
[AuthorizeLevel(AuthorizationLevel.Anonymous)]
public class CustomRegistrationController : ApiController
{
public ApiServices Services { get; set; }
// POST api/CustomRegistration
public HttpResponseMessage Post(RegistrationRequest registrationRequest)
{
if (!Regex.IsMatch(registrationRequest.username, "^[a-zA-Z0-9]{4,}$"))
{
return this.Request.CreateResponse(HttpStatusCode.BadRequest, "Invalid username (at least 4 chars, alphanumeric only)");
}
else if (registrationRequest.password.Length < 8)
{
return this.Request.CreateResponse(HttpStatusCode.BadRequest, "Invalid password (at least 8 chars required)");
}
hadContext context = new hadContext();
Account account = context.Accounts.Where(a => a.Username == registrationRequest.username).SingleOrDefault();
if (account != null)
{
return this.Request.CreateResponse(HttpStatusCode.BadRequest, "Username already exists");
}
else
{
byte[] salt = CustomLoginProviderUtils.generateSalt();
Account newAccount = new Account
{
Id = Guid.NewGuid().ToString(),
Username = registrationRequest.username,
Salt = salt,
SaltedAndHashedPassword = CustomLoginProviderUtils.hash(registrationRequest.password, salt)
};
context.Accounts.Add(newAccount);
context.SaveChanges();
return this.Request.CreateResponse(HttpStatusCode.Created);
}
}
}
I wrote this code on android client app
public void register(View view) {
if ( txtUsername.getText().toString().equals("")
&& txtPassword.getText().toString().equals(""))
{
Log.w(TAG,"tüm alanları girmen gerek");
return;
}
else
{
RegistrationRequest register = new RegistrationRequest();
register.setUsername(txtUsername.getText().toString());
register.setPassword(txtUsername.getText().toString());
mClient.invokeApi("CustomRegistration",register,RegistrationRequest.class,
new ApiOperationCallback<RegistrationRequest>() {
#Override
public void onCompleted(RegistrationRequest result, Exception exception, ServiceFilterResponse response) {
if (exception==null)
{
Log.w(TAG,"kayıt başarılı");
}
else
{
Log.w(TAG,"kayıt başarısız " +exception);
}
}
});
}
}
It's not working. How should I do for registration.

How to extract a value from a facebook invite friends onComplete() response

I am implementing Facebook friends invite in my android app and I need to get to how many friends user sent app request so that I can award him some points.
What I have done so far is as below
WebDialog requestsDialog = (new WebDialog.RequestsDialogBuilder(this,
sessiob, params)).setOnCompleteListener(
new OnCompleteListener() {
#Override
public void onComplete(Bundle values,FacebookException error) {
if (error != null) {
} else {
final String requestId = values.getString("request");
final String[] requestArr1 = values.getStringArray("to");
if (requestId != null) {
Log.e("RequestId1",requestId + "\n" + values.toString());
else {
Toast.makeText(Login.this,"Request cancelled", Toast.LENGTH_SHORT).show();
}
}
}
}).build();
And the Bundle value I am getting is Bundle[{to[0]=808411111111111,to[1]=151584774222222, request=879734911111111}]
While my above code final String requestId = values.getString("request"); working fine however values.getStringArray("to"); giving me Null.
I want to know value "to" inside the Bundle is a StringArray or not and if yes then what's wrong in my extraction process.
