GDPR consent dialog not showing

I followed the guide on the Android docs but for some reason nothing is showing when i start my app.
I even tried logging the listeners but nothing is showing up in logcat.
I also changed the ad technology in admob setting to Custom set of ad technology providers, but still not working.
My code
ConsentInformation consentInformation = ConsentInformation.getInstance(getApplicationContext());
ConsentInformation.getInstance(getApplicationContext()).addTestDevice("6AE7D8950FE9E464D988F340C0D625B0");
ConsentInformation.getInstance(getApplicationContext()).
setDebugGeography(DebugGeography.DEBUG_GEOGRAPHY_EEA);
String[] publisherIds = {""};
consentInformation.requestConsentInfoUpdate(publisherIds, new ConsentInfoUpdateListener() {
#Override
public void onConsentInfoUpdated(ConsentStatus consentStatus) {
// User's consent status successfully updated.
Log.d(TAG,"onConsentInfoUpdated");
}
#Override
public void onFailedToUpdateConsentInfo(String errorDescription) {
// User's consent status failed to update.
Log.d(TAG,"onFailedToUpdateConsentInfo");
}
});
form = new ConsentForm.Builder(this, privacyUrl)
.withListener(new ConsentFormListener() {
#Override
public void onConsentFormLoaded() {
// Consent form loaded successfully.
Log.d(TAG,"form loaded!");
form.show();
}
#Override
public void onConsentFormOpened() {
// Consent form was displayed.
}
#Override
public void onConsentFormClosed(
ConsentStatus consentStatus, Boolean userPrefersAdFree) {
// Consent form was closed.
}
#Override
public void onConsentFormError(String errorDescription) {
// Consent form error.
Log.d(TAG,"form error!");
}
})
.withPersonalizedAdsOption()
.withNonPersonalizedAdsOption()
.withAdFreeOption()
.build();
form.load();
Gradle
dependencies {
classpath 'com.google.gms:google-services:4.3.2'
}
implementation 'com.google.android.ads.consent:consent-library:1.0.7'
implementation 'com.google.android.gms:play-services-plus:17.0.0'
implementation 'com.google.android.gms:play-services-ads:18.2.0'
EDIT
I tried it on a project which was pre android x and now it calls the listener onFailedToUpdateConsentInfo.
With following error message:
onFailedToUpdateConsentInfoCould not parse Event FE preflight response.
Searched a bit and found this could be because of an invalid pub id, but i'm certain i'm using the right one.

1) I think you forget to check isRequestLocationInEeaOrUnknown() method.
It will return true If user already agreed to the consent. In this case, you don't need to ask it again. I think you already agreed to consent.
wrap your code with
if(ConsentInformation.getInstance(context).isRequestLocationInEeaOrUnknown()){
//setup admob
}else{
//Ask for consent
}
2) You have to call form.show(); to present the form to the user, check Google Doc

I was still using test app id and test ad ids, remove them and change it with your id's and make sure you use it as a testdevice so you don't violate admob policies.
Like this
adLoader.loadAd(new AdRequest.Builder().addTestDevice(AdRequest.DEVICE_ID_EMULATOR).build());

Twitter Android SDK not executing Callback

I'm running this code with a Twitter handle I'm pretty sure doesn't exist in order to test error handling. The breakpoints on the Callback are never hit, neither for success nor failure.
Any pointers on why this is?
Just as a note, this code works fine with a valid Twitter handle, but doesn't call the Callback either.
final Callback<Tweet> actionCallback = new Callback<Tweet>() {
#Override
public void success(Result<Tweet> result) {
int x = 1;
x++; // This code is just so I can put a breakpoint here
}
#Override
public void failure(TwitterException exception) {
DialogManager.showOkDialog(context, R.string.twitter_feed_not_found);
}
};
final UserTimeline userTimeline = new UserTimeline.Builder().screenName(handleStr + "dfdfddfdfdfasdf") // Handle that doesn't exist
.includeReplies(false).includeRetweets(false).maxItemsPerRequest(5).build();
final TweetTimelineListAdapter adapter = new TweetTimelineListAdapter.Builder(context)
.setTimeline(userTimeline)
.setViewStyle(R.style.tw__TweetLightWithActionsStyle)
.setOnActionCallback(actionCallback)
.build();
listView.setAdapter(adapter);

I think you misundestood the purpose of the actionCallback. From the source code of the TweetTimelineListAdapter you can see that this callback is for the actions on tweet view,ie, when you click on favorite icon for example. I've test with the favorite icon and the callback gets called.
Take a look at this comment at the getView method of the source code.
/**
* Returns a CompactTweetView by default. May be overridden to provide another view for the
* Tweet item. If Tweet actions are enabled, be sure to call setOnActionCallback(actionCallback)
* on each new subclass of BaseTweetView to ensure proper success and failure handling
* for Tweet actions (favorite, unfavorite).
*/
The callback is not intended to handle a screenname that does not exist and indeed the actions/buttons of a specific tweet.
Hope this helps.
UPDATED: You don't need to detect any erros on UserTimeLine, since the builder does not throw any exception and the adapter will be empty, with no rows/views showing on the screen. But if you still need to detect some "error" in the loading you have to rely on the "next" method of the UserTimeLine.
Take a look
userTimeline.next(null, new Callback<TimelineResult<Tweet>>() {
#Override
public void success(Result<TimelineResult<Tweet>> result) {
}
#Override
public void failure(TwitterException exception) {
Log.d("TAG",exception.getMessage());
}
});
This method shows the next tweet for the user, if the failure callback get called you will know for sure that this user does not have any tweet or the user does not exist.

How to open new page after a successful login GWT Java

I'm making a GWT application that requires users to log in. If username and password are correct, then they are allowed to use the application.
What needs to be implemented in the onSuccess() method to make this possible ?
Thanks in advance.
DBConnectionAsync rpcService = (DBConnectionAsync) GWT.create(DBConnection.class);
ServiceDefTarget target = (ServiceDefTarget) rpcService;
String moduleRelativeURL = GWT.getModuleBaseURL() + "DBConnectionImpl";
target.setServiceEntryPoint(moduleRelativeURL);
rpcService.authenticateUser("admin", "admin", new AsyncCallback<User>() {
#Override
public void onSuccess(User result) {
// What to do here to open or redirect the user to a new page ?
}
#Override
public void onFailure(Throwable caught) {
// Failure
}
});

A simple way of doing this would be to fire an event to the eventbus of you application and then catch this event in the main controller of your application, which would trigger the opening of the right page.
This two pages should explain everything you possibly need to know to do this:
Everything about the architecture GWT MVP
Everything about activity and places (navigation and history)
Just as if you need more information.

From onSuccess you can call a method which will be defined in a corresponding presenter and from that method you can fire an event which will allow user to enter into your application only on successful authentication .

How to change between pages with Selenium

I am trying to create a Test Case with Selenium, where I will create an application in one Page named "Policy". In this Application I want to create some Members. To go from Policy page to Members Page you have to press the button "Members" after you've successfully created the Policy Application. After creating all the members you need you have to navigate back to Policy page to continue.
(Main Menu Page -> Policy Page -> Members Page -> Policy Page)
I am using Page Object Pattern. I successfully log in the App, navigate to Policy Page, create the Application, but cannot go to Members Page in order to continue my Test. And of course, get back to Policy page. How can I do that? My test fails after message "Policy Created succesfully" is shown in Eclipse Console.
My code is:
#Test
public void TEST1_NavigateToPolicy() throws Exception {
MenuPage.policySelection();
}
#Test
public void TEST2_PolicyCreation() throws Exception {
PolicyPage.handleMultipleWindows("Policy");
PolicyPage.createPolicy( some requirements here);
PolicyPage.checkMessageByIdContains("Operation Apply executed Successfully", MESSAGE);
System.out.println("Policy Created succesfully");
}
#Test
public void TEST3_MemberCreation() {
//Navigate to Member Page and Create Member
PolicyPage.clickButton(MEMBERS_BUTTON);
}

Unless I'm testing the actual navigation via the UI I like to do as much navigating as possible by browsing directly to the page I need. It gives the test fewer opportunities to fail, and is often quicker as it can save extra steps.
So, I'd browse directly to the page simply using:
driver.get("yourURL");

Navigation between Policy and Members page can be done by:
#Test
public void TEST3_MemberCreation() {
// Create a policy
TEST2_PolicyCreation();
// Store the current window handle
String policyPageWindow = _webDriver.getWindowHandle();
// Clicking the "Members" button on Policy page
WebElement clickMemBerPageButton = _webDriver.findElement(By.name("MEMBERS_BUTTON"));
clickMemBerPageButton.click();
// switch focus of WebDriver to the next found window handle (that's your newly opened "Members" window)
for (String winHandle : _webDriver.getWindowHandles()) {
_webDriver.switchTo().window(winHandle);
}
//code to do something on new window (Members page)
// Switch back to policy page
_webDriver.switchTo().window(policyPageWindow);
}

Then this will be my sample code for you.
#Test
public void TEST3_MemberCreation() {
homePage = login(admin);
PolicyPage policyPage = homePage.NavigateToPolicyPage();
policyPage.handleMultipleWindows("Policy");
policyPage.createPolicy( some requirements here);
policyPage.checkMessageByIdContains("Operation Apply executed Successfully", MESSAGE);
System.out.println("Policy Created succesfully");
}
MembersPage membersPage = policyPage.clickMembersButton;(You have to handle the page navigation code inside this method and return MembersPage object)
membersPage.createMember(Data);
}
MembersPage clickMembersButton(){
element.click();
switchTo.window(newWindowHandle);
return new MembersPage();
}

stringByEvaluatingJavascriptFromString (iOS method, what is Android equivalent?)

In an iOS app, I used
stringFromJavaScript = [webView stringByEvaluatingJavascriptFromString:#"document.getElementById(\"image\").getAttribute(\"src")"];
To get the src directory of the image that was being displayed on the webView. I want to do the same for Android. What are my options?
Basically the intent is to capture the path so that I can email this same picture...
ie.
"picture.php?image=%#",stringFromJavascript
This way, that same image would be loaded when the user clicks the link, or posts it to facebook etc.

Yeah, I miss this method greatly in Android ;)
To execute JavaScript and get response you can do as follows:
Define JavaScript callback interface in your code:
class MyJavaScriptInterface {
#JavascriptInterface
public void someCallback(String jsResult) {
// your code...
}
}
Attach this callback to your WebView
MyJavaScriptInterface javaInterface = new MyJavaScriptInterface();
yourWebView.addJavascriptInterface(javaInterface, "HTMLOUT");
Run your JavaScript calling window.HTMLOUT.someCallback from the script:
yourWebView.loadUrl("javascript:( function () { var resultSrc = document.getElementById(\"image\").getAttribute(\"src\"); window.HTMLOUT.someCallback(resultSrc); } ) ()");
Hope this helps!
