Starting an other Android app out of a native AppStudio app

I want to initiate an other Android app (here an app synching files) from an AppStudio native app on an Android device. Does anyone have an idea?

You can do this with a plugin like cordova-plugin-app-launcher.

That’s interesting, I will try it

I actually want to call a widget, I don’t think that’s possible with this method

A widget within an app you wrote or one of the device widgets?

One of the device widgets (starting a synchronisation via the app Foldersync)

Can anyone tell me where I can get the uri of an app on Android to start it?

Google Play Store

You can find an app’s package name in the URL of your app’s Google Play Store listing. For example, the URL of an app page is play.google.com/store/apps/details?id=com.example.app123. The app’s package name is com.example.app123.**
