Android ReCaptcha: Checkboxes are not shown

I use Android SafetyNet ReCaptcha to show the Google captcha in my Android app. The problem is that when I test it, the checkboxes are never shown. Instead, the captcha is well shown, and its progress bar is animated a little, and then it finishes without any error, confirming I'm a human. This behavior is normal and there isn't any bug.
But. I would want to force the captcha, which seems to work well as I've described above, to show the checkboxes. By "checkboxes", I mean e.g. "checkboxes showing pedestrian crossings that the human user must claim to recognize by checking". The official documentation doesn't explain how to do it: https://developer.android.com/training/safetynet/recaptcha#send-request

Documentation : 1 link but unrelevant
I've followed this documentation: https://developer.android.com/training/safetynet/recaptcha#send-request . However, it doesn't give any information about how to solve my problem.
StackOverflow : 1 question but unrelevant
I haven't found any relevant question. I've not found, in fact, any question on how to implement ReCaptcha for Android, except a very short one (which doesn't provide any useful data to solve my problem).
My implementation
I'm going to show you how I've implemented their API ReCaptcha for Android (SafetyNet ReCaptcha) to help you to help me.
The process
My app's users can sign-up, sign-in, sign-out.
When a user starts my app, a splash screen appears. If the user isn't connected, he is invited to touch a button.
2.1. If he touches the button, the ReCaptcha is started.
2.1.1. If the ReCaptcha is successfully completed, then the user can sign-up and sign-in with his Google account (I use Google Firebase Auth and even AuthUI).
2.1.2. Otherwise, nothing occurs : he'll have to re-try to complete ReCaptcha.

SplashScreen.java (an AppCompatActivity class): The "onClick" event handler listening to the "touch" event on the button
In résumé: I attach the listener to the button. If the latter is clicked, thus, I call verifyWithRecaptcha in a (synchrone! and it's voluntary) Executor. Then I call the Google's servers to be sure the captcha has been completed by a humain being, not by a bot, thanks to my class NetworkUseRecaptcha which provides the result of the Google's servers.
final Context that = this;
button_splash_screen_recaptcha.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final Executor executor = new Executor() {
#Override

https://developers.google.com/android/reference/com/google/android/gms/safetynet/SafetyNetClient#verifyWithRecaptcha(java.lang.String): "If reCAPTCHA is confident that this is a real user on a real device it will return a token with no challenge. Otherwise it will provide a visual/audio challenge to attest the humanness of the user before returning a token."
So my wish is impossible to concretize...

What's a good way to asynchronously update the progress of ProgressDialog from background thread?

I want to have a Splash screen that has an inderteminate ProgressDialog and its progress gets updated by async calls from within a Presenter class (from MVP architecture).
I have a number of API calls to make to my BaaS server and for every successfull call, I would like to update the progress bar.
What's the best way to accomplish this?
I have been trying using EventBus to send notifications to my SplashActivity but it seems that all the API calls are first completed and only then the bus notifications are getting consumed and updating the UI.
What I have done so far is:
SplashActivity:
#Subscribe(threadMode = ThreadMode.MAIN)
public void onProgressBar(String event) {
Timber.d("onProgressBar");
if(event.contains("Done")) {
roundCornerProgressBar.setProgress(100);
} else {
roundCornerProgressBar.setProgress(roundCornerProgressBar.getProgress() + 10);
}
textViewTips.setText(event);
}
Presenter:
InstanceID iid = InstanceID.getInstance(ctx);
String id = iid.getId();
mDataManager.getPreferencesHelper().putInstanceId(id);
GSUtil.instance().deviceAuthentication(id, "android", mDataManager);
GSUtil.instance().getPropertySetRequest("PRTSET", mDataManager);
GSUtil:
public void deviceAuthentication(String deviceId, String deviceOS, final DataManager mDataManager) {
gs.getRequestBuilder().createDeviceAuthenticationRequest()
.setDeviceId(deviceId)
.setDeviceOS(deviceOS)
.send(new GSEventConsumer<GSResponseBuilder.AuthenticationResponse>() {
#Override
public void onEvent(GSResponseBuilder.AuthenticationResponse authenticationResponse) {
if(mDataManager != null) {
mDataManager.getPreferencesHelper().putGameSparksUserId(authenticationResponse.getUserId());
}
EventBus.getDefault().post("Reading player data");
}
});
}
public void getPropertySetRequest(String propertySetShortCode, final DataManager mDataManager) {
gs.getRequestBuilder().createGetPropertySetRequest()
.setPropertySetShortCode(propertySetShortCode)
.send(new GSEventConsumer<GSResponseBuilder.GetPropertySetResponse>() {
#Override
public void onEvent(GSResponseBuilder.GetPropertySetResponse getPropertySetResponse) {
GSData propertySet = getPropertySetResponse.getPropertySet();
GSData scriptData = getPropertySetResponse.getScriptData();
try {
JSONObject jObject = new JSONObject(propertySet.getAttribute("max_tickets").toString());
mDataManager.getPreferencesHelper().putGameDataMaxTickets(jObject.getInt("max_tickets"));
jObject = new JSONObject(propertySet.getAttribute("tickets_refresh_time").toString());
mDataManager.getPreferencesHelper().putGameDataTicketsRefreshTime(jObject.getLong("refresh_time"));
} catch (JSONException e) {
e.printStackTrace();
}
EventBus.getDefault().post("Game data ready");
EventBus.getDefault().post("Done!");
}
});
}
Right now I am just showing you 2 API calls, but I will need another 2.
Thank you

I found the answer! It's easier that I thought, which is unfortunate as I spend about 4 hours on this:
First, I created two new methods on my MVPView interface:
public interface SplashMvpView extends MvpView {
void updateProgressBarWithTips(float prog, String tip);
void gameDataLoaded();
}
Then, in the presenter itself, I call every API call and for every call, I update the View with the updateProgressBarWithTips method and when everything is completed, I finalise it so I can move from Splash screen to Main screen:
private void doGSData(String id) {
getMvpView().updateProgressBarWithTips(10, "Synced player data");
GSAndroidPlatform.gs().getRequestBuilder().createDeviceAuthenticationRequest()
.setDeviceId(id)
.setDeviceOS("android")
.send(new GSEventConsumer<GSResponseBuilder.AuthenticationResponse>() {
#Override
public void onEvent(GSResponseBuilder.AuthenticationResponse authenticationResponse) {
if(mDataManager != null) {
mDataManager.getPreferencesHelper().putGameSparksUserId(authenticationResponse.getUserId());
}
getMvpView().updateProgressBarWithTips(10, "Synced game data");
GSAndroidPlatform.gs().getRequestBuilder().createGetPropertySetRequest()
.setPropertySetShortCode("PRTSET")
.send(new GSEventConsumer<GSResponseBuilder.GetPropertySetResponse>() {
#Override
public void onEvent(GSResponseBuilder.GetPropertySetResponse getPropertySetResponse) {
GSData propertySet = getPropertySetResponse.getPropertySet();
GSData scriptData = getPropertySetResponse.getScriptData();
try {
JSONObject jObject = new JSONObject(propertySet.getAttribute("max_tickets").toString());
mDataManager.getPreferencesHelper().putGameDataMaxTickets(jObject.getInt("max_tickets"));
jObject = new JSONObject(propertySet.getAttribute("tickets_refresh_time").toString());
mDataManager.getPreferencesHelper().putGameDataTicketsRefreshTime(jObject.getLong("refresh_time"));
} catch (JSONException e) {
e.printStackTrace();
}
getMvpView().gameDataLoaded();
}
});
}
});
}
I hope this helps someone, if you're using MVP architecture.
Cheers

I having some issue in creating a dialog of type group in quickblox chat service on android.

}
i need to know were exactly i have to configure the chat service to prevent the null pointer while creating a dialog.
Any help would be appreciated thank you.

You're right,
chatService.getInstance().getGroupChatManager();
is null if you're not logged in ti Chat
so you have to login to chat first and then call this method

I managed to solve this issue.
First you need to check roomChatManager if its equal to null you have to ask the user to login in.
Second in the login wether your using social provider or by mail you have to login to chatService ( ApplicationSingleton.getInstance().chatService.login(userResult);)
ApplicationSingleton is a java class were it extends Application in it you initialise the ChatService.
Thats it now you can create your dialog successfully.

Facebook Login doesn't work when I use Samsung Android 4.2

When I use HTC Android, it do very well. However, when I use API of Facebook to login using Samsung Android 4.2, I show an Toast message like "login fail please contact the marker of this app and ask them to issue 1732910 to facebook"

});
}
};
}

Found a solution to my problem. Try deleting the android:noHistory="true" from the Facebook login activity in your manifest. This messes with the authentication flow of the Session.

It looks like people on XDA have had this same problem.
They are claiming that you can try either of these:
(1) "Don't keep activities" option on Settings > Developer Options. If it's ON, then when an app calls some popup, system closes app, so then system restarts it ... and there got your loop.
(2) If you uninstall the Facebook App, you can then login through your app, and then re-install the Facebook app.
Not sure how "official" these answers are, but thought it might be worth a shot to you.

Salesforce Rest API with android - NullPointerException # AsyncRequestCallback

I'm trying to get the Salesforce REST API working with Android and new to android programming, followed the sample code to connect with SFDC http://wiki.developerforce.com/page/Getting_Started_with_the_Mobile_SDK_for_Android#Authentication
I'm trying to get a few records from SFDC and display them in the android app, looks like when the Async Call is made at "client.sendAsync(sfRequest, new AsyncRequestCallback()" - NullPointerException is thrown.
I did see a couple of similar issues online, but didn't help me. Hoping if some one would point me in the right direction to troubleshoot this. Thanks much.
public class GetAccountsActivity extends Activity {
private PasscodeManager passcodeManager;
private String soql;
private String apiVersion;
private RestClient client;
private TextView resultText;
private RestRequest sfRequest;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get Api Version
apiVersion = getString(R.string.api_version);
//Create Query
soql = "select id, name from Account limit 10";
// Setup view
setContentView(R.layout.get_accounts_activity);
((TextView) findViewById(R.id.Acc_Title)).setText(apiVersion);
// Passcode manager
passcodeManager = ForceApp.APP.getPasscodeManager();
}
#Override
public void onResume() {
super.onResume();
//Get SFClient
// Login options
String accountType = ForceApp.APP.getAccountType();
LoginOptions loginOptions = new LoginOptions(
null, // login host is chosen by user through the server picker
ForceApp.APP.getPasscodeHash(),
getString(R.string.oauth_callback_url),
getString(R.string.oauth_client_id),
new String[] {"api"});
new ClientManager(this, accountType, loginOptions).getRestClient(this, new RestClientCallback() {
#Override
public void authenticatedRestClient(RestClient client) {
if (client == null) {
ForceApp.APP.logout(GetAccountsActivity.this);
return;
}
GetAccountsActivity.this.client = client;
}
});
//Get Rest Object to query
try {
sfRequest = RestRequest.getRequestForQuery(apiVersion, soql);
//Use SF Rest Client to send the request
client.sendAsync(sfRequest, new AsyncRequestCallback(){
#Override
public void onSuccess(RestRequest request, RestResponse response){
//Check responses and display results
// EventsObservable.get().notifyEvent(EventType.RenditionComplete);
}//end onSuccess
#Override
public void onError(Exception exception) {
//printException(exception);
EventsObservable.get().notifyEvent(EventType.RenditionComplete);
}//End Exception for Async Method
});
}catch (UnsupportedEncodingException e) {
//printHeader("Could Send Query request");
//printException(e);
return;
}
}
}
enter code here

You are calling client.sendAsync from onResume() but client is not set until the authenticatedRestClient callback is called, you need to move your sendAsync call into the authenticatedRestClient callback.
