How to determine the minimum Android version compatible with an ionic app

Ionic Framework
1

Hi to all

I have a problem with the deploy of a ionic app, the project info are the following:

$ ionic info

Ionic:

Ionic CLI : 5.4.2
Ionic Framework : @ionic/angular 4.11.1
@angular-devkit/build-angular : 0.801.3
@angular-devkit/schematics : 8.1.3
@angular/cli : 8.1.3
@ionic/angular-toolkit : 2.0.0

Cordova:

Cordova CLI : not installed
Cordova Platforms : android 8.1.0
Cordova Plugins : not available

Utility:

cordova-res : 0.15.1
native-run : 0.2.9

System:

Android SDK Tools : 26.1.1
NodeJS : v10.16.3
npm : 6.9.0
OS : Windows 10

The problem is that the app work completely only with Android version equal or above 6, even if the
minSDKversion is 19 (Android 4.4). In particular on Android 4.4 georeferencing does not work, even if the app installing and run

How do I know on which version of android I should not allow installation? And more important how do i limit app installation to certain android versions only? is it enough to change the minsdkversion in the project’s config.xml file?

No one knows the answer to my question? I will be grate for any suggestion!!

Hey, I think Ionic supports Android version 5 and up. If you want to limit the version of Android that your app supports, I believe setting the minSdkversion to 21 in Android Studio is enough.

Hi Mitchrockz1 thank you very much for your answer, I had some doubts about the way to limit the installation to only some android versions, but if you confirm me that it is enough to change the minSdkversion, then I feel safer, thank you again.
meanwhile what about the working of the app, it is confirmed that not all the function of ionic 4.11.1 working in android 5, for example georeferencing?
