~ swim ~ thanks , could you please mention any one you know who has used Android before?

Answer 2

Since the app works on newer versions of Android, it's likely using a newer API that is unsupported in the older version of Android.

You'll need to review your code for any such API references and implement a fallback alternatives or set minimum and target SDK versions in the manifest.

It could also be an issue with device incompatibility.

Here are some references that might help:

Answer 4

We cannot help you with this information.

If you have access to the phone, turn on "USB Debugging" and connect it to your computer, run your app and check it's logs in your favorite ide.
There should be enough information about the crash. If it wasn't simply search the first line of the exception through your favorite search engine!

You should test your app on various android versions before publishing. You can use "android emulators" for this purpose.

I recommend you to use "Google Firebase crash reporting service" for better debugging after publishing.

Enjoy coddling :)
