Qt Notifier example app does not work

[NobodySpecial]

I am using Qt 5.15.16.

To run this on my android device with a higher sdk version, I had to comment out the following in AndroidManifest.xml:

<uses-sdk android:minSdkVersion="21" android:targetSdkVersion="28"/>

But then the application failed to compile with this error in AndroidManifest.xml Error:

android:exported needs to be explicitly specified for <activity>. Apps targeting Android 12 and higher are required to specify an explicit value for `android:exported` when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.

I fixed the above error by adding android:exported="true" to the activity node in AndroidManifest.xml.

Now the compilation succeeded.

Next, I deployed and ran the application on my android arm64-v8a device.

It runs okay but does not do what the example is intended to do, i.e. display andorid notification when you click on the icons :-(

In summary, I think Qt need to upgrade this example application so that it works with the later versions of android.

btw, I use notifications in my own app. I based my implementation on this example. It used to work. But it does not work any longer.

Any advice would be appreciated.

I found the solution.
Add android.permission.POST_NOTIFICATIONS to AndroidManifest.xml.
This is a requirement as of Android 13.
