Osmdroid and Mapnik tile provider no longer working - android

I have a developed, deployed and previously successful application which uses Osmdroid to load tiles from the default tile provider which is Mapnik
mMapView.setTileSource(TileSourceFactory.DEFAULT_TILE_SOURCE);
or
mMapView.setTileSource(TileSourceFactory.MAPNIK);
Until recently (maybe since today) the tiles on real devices (a phone and a tablet) do not load anymore. I am using osmdroid version 3.0.5. If I try the latest 4.0 version in a small sample project on an emulator, I see '403 forbidden responses' in the logcat when trying to download maptiles. If I switch the tile source to
mMapView.setTileSource(TileSourceFactory.MAPQUESTOSM);
then the map is visible with no problem. I don't see any reported issues on the
Osmdroid web site issues list, nor does a Google search reveal any new problems reported, so I am asking if anyone else sees this new behaviour from Mapnik and might know of a fix?

Please follow Issue 515 to track this issue. We have implemented a fix and we will release a proper update soon.

Having the same problem as well.
Unfortunately, it seems that osmdroid was banned from accessing http://tile.openstreetmap.org. Reading the tile usage policy, I found these two things which might explain why osmdroid got banned:
Heavy use (e.g. distributing an app that uses tiles from openstreetmap.org) is forbidden without prior permission from the System Administrators.
and
Valid User-Agent identifying application. Faking another app's User-Agent WILL get you blocked.
(osmdroid's useragent is "Apache-HttpClient/UNAVAILABLE (java 1.4)" which is pretty generic)

From OpenPisteMap:
If you start getting "403 Forbidden" responses, stop. Don't just
keep hammering away at the server - it probably means that you've been
banned for abusive behaviour and continuing to hammer away at the
server will just extend your ban.
http://wiki.osm.org/wiki/Blocked

You can use this code to set the user agent
HttpClientFactory.setFactoryInstance(new IHttpClientFactory() {
public HttpClient createHttpClient() {
final DefaultHttpClient client = new DefaultHttpClient();
client.getParams().setParameter(CoreProtocolPNames.USER_AGENT, "useragent");
return client;
}
});

React native queries GPS coordinates and gives timeout

We have the next problem:
We are consulting the gps location in order to get a list that contains only those that are close in a radius, but when consulting the GPS it gives us timeout after at leat 40 seconds of waiting.
The problem especially occurs in Android with a Xiaomi Redmi 8 in industrial environments, with less connection than usual or on the move, they don´t have access to LTE all the time.
We use the library # react-native-community / geolocation or navigation.position
Can you help us with any other library or strategy to obtain GPS position that does not consists in the gps wacthing changes on its position all the time? something like getting it on the background..
Code
Geolocation.getCurrentPosition(
position => {
// process the position
},
error => {
console.log(error);
}, {
timeout: 40000,
maximumAge: 0
}
);
As cited from library's github page:
Currently, on Android, this uses the android.location API. This API is not recommended by Google because it is less accurate and slower than the recommended Google Location Services API. This is something that we want to change in the near future https://github.com/react-native-community/react-native-geolocation/issues/6.
There also are some library suggestions in the readme, that actually use Google Location Services API. I've used react-native-location, but this package isn't actively maintained anymore, so I switched to react-native-geolocation-service, which has a very similar API to what you're already using, more specifically the getCurrentPosition.
Perhaps you should give it a try.
react-native-community/geolocation does not utilize the more accurate Google Location Services API, as stated in readme
The recommended library for GPS location (and the one I used) for RN Android is react-native-geolocation-service. Its Readme also mentions a timeout issue which makes me wonder if it is the same as yours:
This library is created in an attempt to fix the location timeout
issue on android with the react-native's current implementation of
Geolocation API. This library tries to solve the issue by using Google
Play Service's new FusedLocationProviderClient API, which Google
strongly recommends over android's default framework location API. It
automatically decides which provider to use based on your request
configuration and also prompts you to change the location mode if it
doesn't satisfy your current request configuration.
So if I were you I would give it a go. The API is meant to be a drop-in replacement for the library you used so migrating should be just a matter of changing packages.

Change in twitter login

As we know, there have been changes in access to the twitter API referring to callbacks URLs.
So far, I have been using the identification callback with firebase, as I indicated here:
This has been working perfectly so far.
I read in the documentation that now you have to indicate the callback, according to android or iOS in the following way:
twitterkit- : // if using Twitter Kit for iOS or
twittersdk: // if using Twitter Kit for Android.
My application is only developed for android.
I have tried all the possible variants, but I always get the following error:
The client application failed validation: Not a valid callback URL format.
The tested options have been:
twittersdk://pfa89MGYola62VIln ........ (MY_CONSUMER_KEY)
twittersdk://MY_APP-android.firebaseapp.com/__/auth/handler
twittersdk://https://MY_APP-android.firebaseapp.com/__/auth/handler
I have activated and deactivated the check "enable callback locking" ...
I've tried everything, I'm a little desperate
For another test, I tried to register the URL callback as if it were the iOS platform
twitterkit-MY_CONSUMER_KEY://
and it was accepted on the first attempt.
I do not mind losing the relationship with firebase, the truth is that I was not using it, but I have a serious problem if I can not connect with twitter again.
I appreciate any help.
I found the solution, I put it here in case it can be of help to someone.
The truth is that it is not well specified in the documentation, you have to take two steps.
First: activate the "enable callback locking" checkbox
Second: indicate the android sdk for twitter, WITHOUT CONSUMER KEY, unlike iOS users.
It would be like this:
I hope it helps

How to get list of downloaded apps (paid/free) by a user from Google Play?

I recently came across this app Purchase Apps, which is somehow able to retrieve apps I've paid for in google play after I signed in using my google account.
I'm trying to find out how it is being done as I want to build a similar app, but for the free apps which were downloaded.
However, I can't find which OAuth API Scope was used for retrieving that information, even after going through the entire list of APIs.
EDIT:
I'm putting a new bounty on this question, as suggested by a similar question I've asked about here, and because here and there I don't see a real answer about how to do it, and what can be done with it.
I'd like to refine the questions into multiple pieces:
What is the API that can be used to get information of purchased apps? Where can I read about it? Please show a full, working example of how to do it.
Can it do more ? Maybe perform search? Maybe show free apps that were installed? Maybe the time they were installed and uninstalled? And the categories of those apps?
Are there any special requirements for using this API ?
EDIT: I'm putting a max bounty on this, because no matter how much I've read and tried, I still failed to make a POC that can query the apps from the Play Store that the user has ever downloaded (name, package name, date installed and/or removed, icon URL, price...), including both paid and free apps.
If anyone finds a working sample, show how it's done, and also show how you've found about it (documentation or anything that has led you to the solution). I can't find it anywhere, and the current solutions here are too vague for me to start from.
Issue is resolved. The exploit has been closed.
We will be closing this bug due to being logged in a Preview version of Android. If the issue is still relevant and reproducible in the latest public release (Android Q), please capture a bugreport and log the bug in https://source.android.com/setup/contribute/report-bugs. If a reply is not received within the next 14 days, this issue will be closed. Thank you for your understanding.
Latest update:
This is a bug and Google will address it in the next update.
We've deferred this issue for consideration in a future release. Thank
you for your time to make Android better
This answer has turned into a conglomeration of ideas and been edited to include information from discussion in the comments.
The androidmarket api, would be a customised api written by the developer. It's not available to the public.
To address your concerns in the comments. The developer would have utilised the current apis available through Android Developer and Google to create a project that manages all of these.
As for accessing Full Account Access, I'm not sure exactly how these developers have achieved this.
I'd recommend using the AccountManager, which is part of android.accounts, has access to credentials and a method getUserData. The account manager has access to passwords and is capable of creating and deleting accounts. This, possibly used with Content Provider
See Udinic/SyncAdapter Authentication.
To reply to your comment:
This blog should help you to get started. Write your own Android Authenticator.
How these apps actually work, I cannot tell you. They may also have different implementations (unless they're a collaborative effort behind the scenes, they most certainly will be different).
One guess. Firstly use GoogleSignInAccount with com.google.android.gms.auth.api.signin.
There a definition for scope, to determine the extent of the permissions the app is granted.
Using requestScopes(), the
public static final String PROFILE
.../ It lets your web app access over-the-air Android app installs.
For example:
GoogleSignInOptions gso =
new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail().
.requestScopes(new Scope("https://www.googleapis.com/auth/contacts.readonly"))
.build();
If full access can be gained a list of all apps used by the account holder can be found and compared to what's on the device.
Package Manager will retrieve a list of all apps currently installed on the device.
PackageInfo provides the details about the app.
INSTALL_REASON_USER will also filter out apps that have been actively installed by the user.
You might want to look at com.google.firebase.appindexing and Log User Actions. Different actions can be tracked.
The users account history is found at https://myactivity.google.com/myactivity.
A helpful link is the OAuth 2.0 Playground.
This github repo node-google-play, using node, is current and will call Google Play APIs. As did the archive that was used as an "unofficial" api, android-market-api, to query the market place.
App 1
The app claims to use the following permissions:
Version 2.1.8 can access:
$ In-app purchases
Other
receive data from Internet
view network connections
full network access
use accounts on the device
prevent device from sleeping
read Google service configuration
Noteworthy, the app doesn't set any permissions when there was a basic, install. I was unable to use any of the features, as I have no paid apps. So for the initial search - there were no permissions needed, which would indicate the app didn't have access to my account.
I checked the permissions - there were none set. So the only thing required was to accept the pop up, as displayed in your question.
App 2
The other app you refer to that does the same thing is more upfront about what is being accessed.
My Paid Apps
SECURITY/PRIVACY NOTICE
The first time you run this app, it will ask for full permission to your Google account. This is unfortunately
the only way to access the required information. No personal
information is stored, no information about your apps is shared with
the developer of this app, nor shared with any third parties.
Everything is kept on your phone only.
I've gone into detail over these apps in this blog post, which was for a university capstone project (no monetary gain). I'm inclined to think this is an exploit in the API and not status by design by Google, as there are no API calls to fetch purchases of apps other than the developer's own app. I hypothesize it's a zero day exploit, in which case there's no legitimate way to access this information.
In case of one of these applications (My Paid Apps), after checking the network traffic it is pretty obvious that it does use the Store's Account page to retrieve the list of paid applications.
Now, the mechanism it uses is the same mechanism that Google Chrome currently, and Pokemon GO supposedly at a point in time used.
In a nutshell, steps to do so are as follow:
Login:
What the mentioned program do for the first step is to log the user in and get access to the user's access token. To do so, it uses the android.accounts.AccountManager.getAuthToken() method. (See more: AccountManager)
However, as for the token scope, oauth2:https://www.google.com/accounts/OAuthLogin is requested.
It might be important to note that based on the OAth2 documentation from Google, this scope is not valid; however, it seems like a valid scope for Google OAuth v1.
Converting the newly retrieved access token to a ubertoken:
Now, what actually ubertoken supposed to do, is unknown and there is no official documentation about it. However, it was seen in the wild to be used by chrome browser to login users.
This is done by requesting the https://accounts.google.com/OAuthLogin?source=ChromiumBrowser&issueuberauth=1 page.
Converting ubertoken to website session:
Later on, using the newly created ubertoken it is possible to get a website session using the https://accounts.google.com/MergeSession API endpoint. After this step, the application is essentially capable of loading all personal pages that you can open using your browser while logged in; except some special pages including Payment settings.
Retrieving the list of paid applications:
Requesting and parsing the https://play.google.com/store/account page.
Following is the application's traffic as captured by 'Packet Capture':
As it is clearly visible in the picture, the end result is identical to what I get when I normally open the store's account page on my PC with Chrome Desktop:
Side note:
It seems none of these endpoints are documented as they are primarily used by Google's own programs and should be considered internal. Therefore I strongly recommend not using them in any program or code that you expect to run for a long time or in a production environment.
Also, there is bad news here for you too, it seems that the Google Play's account page only lists paid applications or special free apps (more especially OEM apps). I will try to find some time and dig deeper into the other application.

Exploiting Google Chrome's OAuth2 Tokens

Dealing with unofficial Google APIs is incredibly complicated territory. It's going to be possible to get this to work, but that's all I'll say. Proceed at your own risk.
The first thing you're going to need to do is get a Google Play auth token. This can be done several ways, but here's how they do it in Purchased Apps:
public static String getAuthToken(Activity activity, String userEmail) {
AccountManager accountManager = AccountManager.get(activity);
Account userAccount = new Account(userEmail, "com.google");
Bundle options = new Bundle();
options.putBoolean("suppressProgressScreen", true);
String token;
try {
Bundle result = accountManager
.getAuthToken(userAccount, "androidmarket", options, activity, null, null)
.getResult();
token = result.getString("authtoken");
} catch (OperationCanceledException e) {
Log.d(TAG, "Login canceled by user");
return null;
} catch (IOException | AuthenticatorException e) {
Log.e(TAG, "Login failed", e);
return null;
}
return token;
}
A few things to note here:
The above code must be run asynchronously. I recommend RxJava, but an AsyncTask will work.
You must supply a email for the account you want to use. I'll leave the details up to you but this is fairly easy using AccountManager.
After you have an auth token, you can now access any Google Play Store endpoint. The main one used by Purchased Apps is https://android.clients.google.com/fdfe/purchaseHistory. Another one you might be interested in is https://android.clients.google.com/fdfe/details?doc=(package name) (from APKfetch code). Here's a page with some more and some analysis. If you make a request to these APIs, you'll need to supply several headers:
Authorization - "GoogleLogin auth=(your auth token)"
User-Agent - "Android-Finsky/6.4.12.C-all%20%5B0%5D%202744941 (api=3,versionCode=80641200,sdk=" + VERSION.SDK_INT + ",isWideScreen=0)";
X-DFE-Device-Id - your device's Google Services Framework ID, obtained from AdvertisingIdClient.
X-DFE-Client-Id - "am-android-google"
Accept-Language - The device's language code, eg "en".
Now, you need to parse the response. Here's where things get tricky. These APIs returns a message encoded as a Protobuf, so it's essentially just binary data unless you have a schema (which of course, only Google has). One way to go about this in theory is to decompile the Google Play Store app and reuse their generated protobuf models with a tool like JADX.
Unfortunately, I've tried this and it doesn't really work. Protobuf model classes are just too complex for a standard decompiler. What you can use is a tool called PBTK. You'll ideally want to run this on the Google Play Store 6.1.12 APK, since that's the last version before they started using ProGuard. Do note that this program has two errors in its script that need to be fixed before running it: changing 'extracto' to 'extractor' in gui.py and removing the assertion statement on line 500 of jar_extract.py.
Now, that should output all of the response classes as .proto files. Create a folder under src/main called proto and drag the entire generated 'com' directory to it. You can delete everything that's not under com/google/android/finsky/protos. Follow instructions online to setup Gradle with the Protobuf Lite plugin.
When you want to parse a response, you can use the ResponseWrapper class, since they all appear to be contained under that.
That's about as far as I can take you. There's a good chance I got some part of this wrong; JADX is your best friend here, because the best way to figure out what an app is doing is by looking at its code. Hope this helps and happy developing!
you can get the package name of all installed apps on device and then get the information of every installed package that you find in the device from google play without any need to get to user account. there is some third party or unofficial apis to get google play apps details as json by getting the app package name. for example: https://42matters.com/
then use the received information for every package to find free ones.
i have two resources for you to consider, but first, in a word, no. there is no api from GOOGLE to let you do what you want, as these metrics arent stored in the phone, they are on the google play store servors, and google has no OFFICIAL api for the play store. you can however glean some info from these two sites:
https://www.quora.com/Is-there-an-API-for-the-Google-Play-Storeenter link description here
https://android.stackexchange.com/questions/162146/how-to-see-all-the-apps-i-have-downloaded-from-google-play-store
and this is enough to see how to accomplish this.
first, a list of what apps have been downloaded by an account is only referencable by the account. and this can be done through the play store. since your app will be installed on that users phone, this dosnt matter... you're in.
second, you will need a 3rd party API built for the GOOGLE PLAY STORE, there are some out there, check the first link.
using the api of your choice, you will send a get request, to the play store, and in return you should receive in most cases a json object to deserialize.
deserialize the object, and you will have your list. which list you get will depend on the endpoint you use, but that should be explained by/in the API itself.
good luck!

can't authorise moves through app link

We are developing an app that should get data from the Moves app API.
When authorising our app on the mobile phone, we manage to do so successfully in the case in which we submit the PIN provided by the desktop link into the moves app:
https://api.moves-app.com/oauth/v1/authorize?response_type=code&client_id=<client_id>&scope=<scope>&state=<state>
In the case where I use the Mobile website / app link instead, this won't work:
moves://app/authorize?client_id=<client_id>&scope=activity%20location&state=<state>&redirect_uri=<redirect_uri>
Note: <redirect_uri>==encodeURIComponent("mymovesconnector:8081/callback").
The response we get from the Moves API is 400: {"error":"invalid_grant"}.
From the docs, it says that invalid_grant can happen if either:
the code in the request is not valid or
the code has expired (it’s valid for 5 minutes currently) or
the code has been revoked, because it was already used in an access token request (both successful and unsuccessful requests will revoke the code) or
you are missing the redirect_uri parameter when it’s required.
My checklist:
I guess this could have happened, but how/why should this code, provided over moves://, be different than the one provided through the https:// request? What control do I have over this?
not my case, since I'm using the code right away within less then a few seconds
if this might have happened, where could it happen other than through the redirect url?
I'm providing it always. It's always the same - also in the app settings on moves.
Can't figure out what I'm missing. Went through the docs many times, step by step. No success.
While writing down my question, I managed to figure out a solution to this problem.
The docs don't point out that response_type=code might also be used for the moves:// link. I tried to add this parameter, and it worked!
Note: this has been tested on a virtual android device only (Genymotion).

Set up TLS proxy for Google Cloud Endpoint APIs

I have been viewing my Google App Engine endpoint APIs in the API explorer (localhost) without issues, now am getting this:
in full it says:
You are exploring an API that is described or served via HTTP instead of HTTPS. This is insecure and may be blocked by your browser. To fix this, set up a TLS proxy for your API. Alternatively, you can tell your browser to allow active content via HTTP at this site (on Chrome, click the shield in the URL bar), but this will not improve security or dismiss this message.
This is one of the API methods I have in my endpoint:
#ApiMethod(
name = "insert",
path = "movie",
httpMethod = ApiMethod.HttpMethod.POST)
public Movie insert(Movie movie) throws UnauthorizedException {
...
}
Since I do not know what's causing this all of a sudden, I do not know what else to show.I've tried updating my browsers (Firefox, Opera, Chrome) with no luck.
The same problem appeared to me today
For now if you are using chrome you can click on the shield icon on the right of the URL bar and click on something saying load scripts anyway and your API should appear.
Image: http://i.gyazo.com/f16a557c4b53c147f31067029d15c093.png
You will likely want to use a browser-based workaround, such as the shield icon on Chrome. This was recently added to address a security vulnerability. Unfortunately, we are unable to do better than this. A colleague suggests that stunnel may be viable for setting up a TLS proxy, if you want to go that route.
