Deeplinking Squareup pos app is not working

The documentation link: https://developer.squareup.com/docs/pos-api/build-mobile-web#step-5-test-your-code suggest straight forward code like this:
<a href="intent:#Intent;
action=com.squareup.pos.action.CHARGE;
package=com.squareup;
S.browser_fallback_url=https://my.website.com/index.html;
S.com.squareup.pos.WEB_CALLBACK_URI=https://my.website.com/index.html;
S.com.squareup.pos.CLIENT_ID=sq0ids-yourClientId;
S.com.squareup.pos.API_VERSION=v2.0;
i.com.squareup.pos.TOTAL_AMOUNT=100;
S.com.squareup.pos.CURRENCY_CODE=USD;
S.com.squareup.pos.TENDER_TYPES=com.squareup.pos.TENDER_CARD,com.squareup.pos.TENDER_CASH;
end">Start Transaction</a>
I tested it and it does not open any link, my devide already have app installed.
When I try this code:
Take a QR code 2
It open play store app with squareup pos app information, I need to directly open the app and not play store screen of the app, is there any way?

*UPDATE:
I got transactions to work after adding S.com.squareup.pos.LOCATION_ID={{ my_location_id }}. The location ID can be found in Square Developer Portal > Locations. Also if the POS app is passcode protected, you have to open and login with passcode before sending transaction.
*END UPDATE
I've been working through this same issue. I still haven't gotten a transaction to work, but have at least gotten the app to open.
Make sure the CLIENT ID is your production application ID. NOT sandbox.
The WEB_CALLBACK_URI needs to match the Web Callback URL defined in your Square Developer Portal > Point Of Sale API.
I hope this helps. If you do figure this out and get transactions to work, please post your solution for me and others who are sure to run into this issue since the documentation is lacking.

branch.io deep-linked URL not passing data in App from Facebook Ads

We are using branch.io to pass custom data to App. For that we are following this steps in branch dashboard.
1) Ads -> Partner Management -> Facebook -> Create Facebook Link
2) Set data in Key/Value under "Deep Linking" Section (data which we need in our app)
3) We set Play/App Store URL in Android/iOs respectively Or set Default Redirects under "Redirects" section
That's it!!!
Now Go to Facebook Ads Manager and select App Install Campaign.
1) Select Play/App Store under App Section.
2) Set above generated URL under "deffered deep link"
You can read more here : https://docs.branch.io/pages/deep-linked-ads/facebook-app-install-ads/
Now Our Problem is :
When user clicked on any branch link with deep link params it able to receive data in both case when user fresh install the application and if user has already app installed.
When we clicked on Facebook ads with same url we are unable to get branch data if user has not installed application (Mostly in case when user redirect from App Store/play store) . But user has installed the app we can able to receive all branch data from same url.
So Question is:
1) Do we need any permission from Facebook or missing any configuration on Branch or Facebook?
2) The same thing will work with both (e.g. Android and iOs) devices?
Thanks

Unfortunately the branch.io documentation for setting this is up is pretty incomplete - we just spent about a week testing and debugging the SDK to figure out how to get it to work. The necessary changes itself are actually quite simple.
On Android:
Integrate the Facebook SDK if you haven't done so already
Ensure that the facebook_app_id string resource you added as part of (1) is not prefixed with "fb"
If you are using ProGuard, add rules to keep the relevant parts of the Facebook SDK
Call enableFacebookAppLinkCheck() on your Branch instance right after initializing it
On iOS:
Integrate the Facebook SDK if you haven't done so already
Call registerFacebookDeepLinkingClass(FBSDKAppLinkUtility.self) on your Branch instance right after initializing it

I had this exact same problem, but in a React Native project, so I'm using react-native-branch. #henning-dodenhof 's answer helped me a lot (thanks for figuring this out!), but I needed a couple of further adaptations, so I add this answer in case it's useful for someone else since this post was the main thing I found regarding this issue:
For iOS:
The FB SDK registration needs to happen before initializing Branch, not after as the above answer suggests. So, before this line that you add as part of the normal library setup:
[RNBranch initSessionWithLaunchOptions:launchOptions isReferrable:YES];
You need get the Branch instance from RNBranch and then register this FB SDK class:
[[RNBranch branch] registerFacebookDeepLinkingClass:[FBSDKAppLinkUtility class]];
Adding this new line before the initialization is critical, doesn't work if it's done after.
For Android:
Here the setup code already gets an instance with Branch.getAutoInstance(this), so we can just chain the registration:
Branch.getAutoInstance(this).enableFacebookAppLinkCheck();
It looks like the getAutoInstance above doesn't actually fully initializes the instance, so you can call enableFacebookAppLinkCheck right after, and the instance gets fully initialized after the first use.

How to inform about app update for an app that is 'not in market' but on a drive, programatically?

I have made an app for my friends so that they can view class notes.The app is not available on play store. Every time I update the app, I upload the new apk file to google drive.I want to write a simple code in my app that can inform if a new version is available or not.How can I do this?I don't want the user to automatically download the new version instead prompt the user to download the new version by clicking a button

In the same Drive folder that you post your app, you can also put a text file, call it something like version.txt. In this file, just put the version number of the latest version of the app. It can be as simple as an integer that you increment each time you post the app.
Then at startup, your app can do the following:
Download the version.txt file, and note the version number. Call this V-Drive.
If a locally-stored version exists, read it. If not, save the value of V-Drive to SharedPreferences. Call this V-Local.
If (V-Drive > V-Local) display a message telling the user that there is a new version available for download.

You can use FABRIC. Make registration and after that get the CRASHLYTICS(A tool from Fabric made for testing purposes). It is quite easy to use and they are explaining step by step what to do in order to activated it. After that you can just add them in the list of testers and at the moment you release new version it will send them email with the updated app. I use it for work and it is working quite nice and it looks professional.
Good luck!!!

Android Play Store market:// link is no longer working?

I've been redirecting my users for the past year from my domain:
http://example.com/get
to: market://details?id=com.example.myapp
Today I've check this on Nexus 5/LG G3/OnePlus One from the chrome browser app and it stopped working!
Now, when my users try to download the app they are redirected to a broken link.
Anyone know anything about this change in the Chrome app in Android?

from reading the chrome's version 40 release, there are some insight i d like to share
http://blog.chromium.org/2014/12/chrome-40-beta-powerful-offline-and.html
they updated to Content Security Policy Level 2, which has a stronger control over redirects.
https://w3c.github.io/webappsec/specs/content-security-policy/#changes-from-level-1
The path component of a source expression is now ignored if the resource being loaded is the result of a redirect, as described in §4.2.2.3 Paths and Redirects.
Redirects are blocked by default, and explicitly allowed with a new unsafe-redirect expression.
So I did some testing. if your initial action started from redirect (no matter window.location or http 302) it will show an error. but once i created a hyperlink to market:// and explicitly clicked it, it worked fine.
for now i ended up creating a webpage in between, where i ask the user to click the link to proceed.

I was testing this url on different devices with different OS/Play Store/ Play Services/ Browsers. looks like it's related to browser but not OS or Play Services.
Initially I updated Play Services and Google Play Store and my old Chrome (v18) was opening market://details?id= url fine.
Afterward I had updated my Chrome (v18) to version 40. And it's not working any more.
Meanwhile, FireFox and default "Browsers" still opens this url and redirects to Google Play Store app.
P.S. I have registered issue in Chromium bug tracker. Let's see if there will be any response:
https://code.google.com/p/chromium/issues/detail?can=2&q=market&colspec=ID%20Pri%20M%20Week%20ReleaseBlock%20Cr%20Status%20Owner%20Summary%20OS%20Modified&id=454396&thanks=454396&ts=1422888121
UPDATE [6.05.15] : Unfortunately, they decided not to fix this issue, saying, that it's planned behaviour. As they said, user should click the link by himself. Only then re-direct to the app on devices is allowed.
So, there is only one "work-around", that I see for now: create a page, that contains text like "Click link below to go to the app", followed by link like:
Load Example App
or
<a href="intent://foo.bar#Intent;scheme=blabla;package=com.example.myapp;end" > Load App/ Activate your Profile </a>

Try the link below, replacing your.app.id with your own identifier:
https://play.app.goo.gl/?link=https://play.google.com/store/apps/details?id=your.app.id&ddl=1&pcampaignid=web_ddl_1

TestFlight intergration Android

Unable to receive crash reports on my Test flight account even though application gets crashed.
I integrated the SDK in my application. I did following steps -
1. Integrated SDK in code
2. Used proper Application ID
3. Started session using TestFlight.startSession();
4. Called TestFlight.sendCrash(121213, "XXX", "YYY"); method
4. Ended session using TestFlight.endSession(); in one of my destroy() method.
Let me know if I am doing anything wrong or missing anything.
Thanks in advance, your answers will be much appropriated.

Crash sessions should be sent back to TestFlight automatically. There is no need to specify startSession, sendCrash, and endSession. Please contact TestFlight support here (http://help.testflightapp.com/customer/portal/emails/new) so we can further investigate. Please include the URL to the build's permissions page in the email.
Thanks,
Justin (TestFlight Support)
