Showing on which device an app release is installed in Google Play Store? - google-play

I have released an application as an internal test. I have seen that one device (about 14.28% of all devices) has an old release installed. Now I would like to find out the device. Is it possible to get more information about the devices which installed an app release? (e.g. device name or something like that)? And how often are the release details for internal tests updated in the Google developer console?

What defines an unknown source in Android Auto

Currently,
My team and I are developping an Android Auto enabled app. And it appears to me this app is only available in my car unit, when I enable unknown sources in the Android Auto app.
However I'm wondering what defines an unknown source and how do I make sure my app is not an unknown source. Does Android Auto communicate with the Google Play Services for this or do i need to sign the APK with specific data?
How are you deploying your app? If you are deploying with Android Studio: as I recall you won't see it on your real automotive head unit, just the emulator. To show on the head unit it needs to be deployed in the Play Store, at least in developer and pre-release mode while under development.
First of all: Android Auto runs on your own device, meaning it adapts the same permissions you granted to particular apps. If your app doesn't have an app in the normal UI or you didn't open it on your phone once, then it would usually prompt you to grant permissions the first time you open it.
An unknown source is pretty much any way of getting your app outside of the Google Play Store (and OEM-specific app stores like Samsung App Store for Samsung devices etc.).
That is especially common if you e.g. download an .apk from the internet and want to install it, but your phone thinks their own file manager is an unknown source (because it is not intended to download apps).

not able to add .ipa file in iphone device

i have generated the .ipa file and trying to add in any iphone device but its not adding.
the error is showing like:- couldnot install(in xcode).
i tried with apple configurator 2:- in this scenario app is installing a bit just assume
75% and after that the app icon is getting grayed out and clicking on that app is giving
popup as :- could not install please try later.
somewhere i saw that you have to allow from your device to trust this app, location is like :- settings > general > profile&management > you will find your profile here for new app installing.i didn't get any profile there.
FYI
i am using free developer account and created the xamarin app from windows and building it through mac, the xcode version is 9.4 beta and i also tried to override with xcode version 11.3.
i am not getting whether i am missing something or messed up with xcode versioning.

If using a free apple developer account , you can not install a .ipa file to iOS Device .This is limited by Apple.
About IPA Support in Xamarin.iOS , you will see there are two uses as follow :
Ad Hoc Testing — An iOS application can be deployed to up to 100 users (identified by specific iOS device UUIDs) for Alpha and Beta testing purposes. See our Provisioning an iOS Device for Development documentation for detailed information on adding test iOS devices to your Apple developer account, and the Ad-Hoc guide, for more information on how to distribute in this way.
In House / Enterprise Deployment — An iOS application can be deployed internally, within a company, which requires membership of Apple's Developer Enterprise program. More information on In House Distribution is detailed in the In House Distribution guide.
In either case, an IPA package (a special type of zip file) must be created and digitally signed with the correct Distribution Provisioning Profile.
If using a free provisioning , there is a Limitation as follow :
Access to iTunes Connect is limited and therefore services such as publishing to the App Store and TestFlight are unavailable to developers provisioning their applications freely. An Apple Developer Account (Enterprise or Personal) is required to distribute via Ad Hoc and In-House means.
Therefore , if need to add .ipa file in iphone device , you should use a paid Apple Developer Program account.

Enrolling Android 5.1 device fails without reason

I am trying to enroll a fleet of Android 5.1 devices which did never receive a newer version of Android and are not working with any third party ROM. So we're stuck on 5.1.
As the Google Play Services in the ROM was so old, that I couldn't even install the Android Device Policy DPC, I updated the Play Services in the ROM using an update.zip, wiped the device and then enrolled the device using a NFC tag.
Unfortunately, enrollment is not working, and I'm not even getting an error message. The DPC seems to set itself as the device owner, but no enrollment is taking place - the device does not show up on the API, and upon launching the DPC from the application drawer and clicking on the "Get started"-button, we always are presented with "Your system cannot be managed by this app. Please contact your administrator".
Well, I am the administrator and I have no clue, why this is failing.
Has anyone an idea, what the DPC is looking for before deciding that the device cannot be managed? Or how to get a more meaningful message out of the DPC?
The Android Management API doesn't support NFC provisioning on Android 5.1. It is only supported on Android 6.0 and above.
The documentation previously mentioned that 5.1 is supported, that was an error and we have now updated it.

Play store Download to all devices?

I've configured an email ID (obviously gmail id) to 20 android devices all are situated at different place now if i want to install an application. to all device like Avast antivirus
if any device have already installed then how could i be able to do this.
Goal :
1: Install an application to all devices if not intalled.
2: devices may have already intstalled application then it will show install say if one have intall and other don't then how to install in all devices.
I am not too versed in telephony. I know for blackberries you have to have a blackberry [enterprise] server to manage devices in this fashion. I think one client for android is called Good, but if you do a search for android enterprise management, you probably could find others.

Xcode App Distribution to Friends

Yesterday I saw a Website of a Company which has a test version of their iPhone App downloadable for everybody from their website.
Since I am an Apple Developer, I know that you need the UDID of the target device to declare it as a test device, because you have to code sign it to the device.
When I have downloaded the file, it was a normal App file from Xcode. I dragged it to iTunes and from there to my Device, and what do you suppose happened?
Yes; it worked on my Device!! ;-)
I have not jail-broken my device and the app Works on any device I have tried it on without add the devices to any Developer Account...
Does anybody know how to do this???
How can I distribute an app to any device by email or web download without adding test device UDIDs to my account to work on any phone???
Thanks.
The company could either have distributed it as a source code (which can be run by anyone with a developer's account) or by a link to the app store
You can either do one of two things to distribute an app Adhoc:
1 . As a normal App developer you add devices UDIDs separately to the developer portal.
or
2 . Create a company Adhoc developer's account (which costs extra money and DOESN'T allow you to post to the app store (but that also requires UDIDs))
Alternatively you can post it on the app store and distribute it via that method.
Due to code signing only jailbroken devices may run unsigned apps (or apps not signed for them)
I'd love to know how they do that. I do the next best thing: I use testflightapp.com to distribute my apps. It does require UDIDs but easily collects them, and deployment to those users is one touch after building/uploading. There is also a feedback API that I find quite handy.
