Nokia T20 - Google Play says device is unsupported

We are looking for new tablets now that the Lenovo M10 Plus FHD 2nd Gen is discontinued, and the 3rd Gen won't work since the buttons are too close to the corner to fit in our tablet holders. We are currently testing the Nokia T20.
We just noticed that one of our apps is listed as unsupported in the Nokia T20. I don't see any feature or limitations that would make it incompatible. Here is the manifest:

Perhaps the Nokia T20 could be reporting its screen size incorrectly? Could you help me out? Thanks.

Android app not compatible by any device

We have published an iOS version of our app successfully, but Android is failing. We have deployed it into the Google Play store, but there we get the message that it is compatible with 0 Android devices (which is not a good thing obviously). The following file is the AndroidManifest.xml file found in the APK after compilation on PhonegapBuild (so this is the APK we send to the Google Play store).

The funny thing is that a local build of the app works on my Android device, but it does not work after sending it to PhonegapBuild and then send it to Google Play store. Also worth mentioning is the fact that I can run it on my device from PhonegapBuild, but not from the Google Play store.
Some other facts: the app is build using Ionic (and PhonegapBuild).
What am I doing wrong here?

Can I integrate Microsoft Lens into my application?

I like Office Lens's ability to automatically crop, focus, and align a picture... mainly for receipt and expense processing
I want to have an app flow that goes like this:
User opens my app and clicks photograph receipt
Lens opens (android intent, or similar in iOS)
User takes picture
Picture is returned to my application for processing
I am having trouble making that flow happen, and to make the data transfer (photo) between the camera and my app seamless. What options do I have?

If you read this file carefully you will see that this is impossible to interact this the other API's. Neither 'broadcast' no proper 'intent-filter' to interact this the other applications.
This is impossible nowadays.
Anyway, obviously, you can save to local storage and retrieve the data from SD card using your app.

Library installed as application Android

Best Regards

Remove this part from your library's AndroidManifest:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

Its showing 2 launcher icons as both your library manifest and application manifest have following:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
This instructs to enable the activity to be launched by a launcher icon directly. If you remove this from your library manifest. That should fix it. Hope it helps.
