Alpha Testing - "This app is incompatible with your device" - android

I'm trying to test the licencing on an app:
Uploaded the apk as an alpha to google play in the dev console
added tester emails
visited the testers' link once it was published and live
Problem: It says my device is incompatible with the app!
I debugged directly from Android Studio via usb on the same device, and when I upload the apk to my phone, I can install it directly.
Also, Google Play gives me no hints as to what the issue of obstruction is. How do I debug this issue?

In cases like this, keep an eye on the details: I had the noob error of using maxSdkVersion instead of the proper minSdkVersion - an oversight of 2 characters.

Distribute apk outside play store (to non gms devices)

I have this app released on play store that I want to make available on my website. I tried downloading the signed apk via the Google play console and use that, but some users in China have issues installing it.
They get a message like this while installing: "Your device does not support Google Play Services and cannot install "
I have a few Google sdk bits referenced in my project (signin, safetyNet, ads) which I would assume I need to delete before building for this apk version, since target devices don't have gms..
What about signing? Can I simply build without the said code and distribute it? (Generate release apk in android studio) Or do I need to upload to play console and download the one signed from google?
Please let me know if you have any clues on this, been banging my head around for a few days already.
Cheers :)
This might help you taking your decision:
If you have Play App Signing enabled, the APK generated through your studio and the APK generated through Play Console will have different signatures.
Otherwise, both approaches will have the same signatures.
So, it depends whether you care about your APK on website having the same signature as Play Store. If you don't care about having same signature, you can go ahead with creating APK from Android Studio itself and publish to your website.
If your app utilizes Google Play Services, as is informed by the error message, then it WILL not run on the device unless Google Play Services and everything that it depends on is installed on the device. The only work around is to convert your app features that uses Google Play Services to its alternative that's supported in China.
I've dealt with similar issue on Huawei smartphones, my approach was to 'develop another app' using Huawei SDK, check out https://developer.huawei.com/consumer/en/ for its complete reference

Can't publish Xamarin.Forms App's APK file on Google Play Store

I want to publish my Xamarin.Forms App to Google Play Store. But when I upload the APK it gives me warning and disables roll-out option. It says we need to use Android App Bundle (.aab) format so that APK can be optimized for size and resources.
Currently, Visual Studio 2019 Archive option does not support the Android App Bundle. I have taken latest update of Visual Studio 2019 but still above format is not supported.
I googled and found some link to do this from the command prompt by modifying some settings in the Project file. But the build returns errors after couple of minutes with exit code 1.
This is frustrating as I can't publish it to Google Play Store. I have already published the iOS version of App.
Any help here will be very much appreciated.
Me and my team are currently releasing to Google Play with no problems our app as APK.
The App Boundle is a nice way to release smaller applications by delivering just what the device that downloads your application needs. The Xamarin Show published recently a video on this topic, that could be of interest for you:
https://www.youtube.com/watch?v=_IOZ0SUKZq4
Through the following images i show how we upload/publish our APK:
First, in the image below you see that APKs are still supported:
APK uploads correctly:
Then we are able to save and review the APK:
APK is uploaded with warning:
The warning states:
For now we just ignore the warning and go on to roll out:
In case that after following those steps your Start Rollout option is not yet enabled, it might be the case that you still have some other Listing Sections for your Application. After you introduce all the information required by Google, the Start Rollout option must be available.

App requires latest version of ARCore. Google Play Services for AR says my device isn't compatible with this version

What steps do I need to take when I have troubles trying to use an app I created and try to run it on the latest Samsung Tab A 10.1? I tried to start the app, the message displayed is :
This application requires the latest version of ARCore
So I tapped the continue button. I was taken to Google Play. The title says "Google Play Services for AR". Then below that it says:
Your device isn't compatible with this version
Does anyone have a solution, please?
Firstly check whether the device you are using has the ARCore support:
It was indeed an easy experience in terms of building and running the app on the IOS device, iPhone 10. There were no complications in activating the ARkit in the devices since they were built in like the documentation mentioned. It was particularly gruesome in building the AR app on an Android device. As per the documentation the Android devices such as Samsung Galaxy A70S is compatible with ARCore.
Firstly the app simply crashed on installing into the device
As a part of the workaround, I looked for installing, "Google Play Services for AR" on my play store which simply didn't show up
I directly tried to install the app "Google Play Services for AR" through google but it failed with the message, the app is not compatible with my device.
I did a trial and error with installing the "Google Play Services for AR" apk directly from https://www.apkmirror.com/apk/google-inc/arcore/, specifically https://www.apkmirror.com/apk/google-inc/arcore/arcore-1-13-19100710-release/google-play-services-for-ar-1-13-191007106-android-apk-download/ to my Android device to enable ARCore which supported 64-bit processor
The app was however still crashing due to the 403 forbidden IP error on persisting the data
The issue got resolved on adding my public IP to azure rules

Delphi XE6 App Crash when installed from Google Play Store

Yesterday I created an Android app using Delphi XE6, built it with Release configuration and targeted App Store, and ran deployment without installing to any device.
I then uploaded the resulted APK to Google Play Store with success, but when the app downloaded and installed on my device (ZTE N986D), it crashed.
THE SAME APK downloaded to the device via http server running on my laptop was fine and working without any error/crash.
I did triple checks everything (debug/release mode, provisioning, deployment files, etc.) with no luck. I also did try on 3 differend Android devices with exactly same result.
For now I believe that this is not a bug on Delphi XE6.
Is an APK getting changed when uploaded to Google Play Store?
Here is link to the app:
https://play.google.com/store/apps/details?id=org.cenadep.pnup.qrkasir
Any help and thought would be appreciated.
1) You need to generate a keystore for sign your APK.
Please follow this link to create a keystore: http://docwiki.embarcadero.com/RADStudio/XE6/en/Creating_a_Keystore_File
2) After, follow this: http://docwiki.embarcadero.com/RADStudio/XE6/en/Deploying_Your_Signed_Android_Application

Application not Installed error when referencing Mono.Android.GoogleMaps

I am working on a new update to my app and added google maps support. I added a reference to the Mono.Android.GoogleMaps assembly. All works great, tested good on my Droid X device so I sent the .apk to beta testers. I then tried to install on my Kindle Fire (allowed unknown sources) and it failed to install. I also got a report from a beta tester that they got the same message on their Motorola Photon.
I've later learned Kindle Fire and NOOK don't have the Google Maps integration. I've already built around "location" permissions although not sure if that was required.
I just fired up a AVD for Kindle Fire per the Amazon info and tried deploying a debug build. I got this error message:
How do you suggest I proceed? If this issue IS google maps being referenced, how do you handle this so my app will run on devices without this shared library present? What do I test for in code as to when to allow features such as this?
Thanks.
I researched the issue and added this line to my AssemblyInfo.cs and now it installs to Kindle Fire.
[assembly: UsesLibrary(Name="com.google.android.maps", Required=false)]
