Ionic 3 android permissions internet

I'm writing an app that sends requests to a REST API.

The API calls work in the web browser, but not in the emulator and not on a device.

Ionic CLI 4.4.0

Cordova 8.1.2

What i did:

I use android-permissions like on this side:

app.modules.ts

import { AndroidPermissions } from '@ionic-native/android-permissions';
@NgModule({
  declarations: [
  ],
  imports: [
  ],
  entryComponents: [
  ],
  providers: [
    AndroidPermissions
  ],
  bootstrap: [IonicApp]
})
export class AppModule {}

api-call.ts

import { AndroidPermissions } from '@ionic-native/android-permissions';
export class ApiCallPage {

    constructor(private androidPermissions: AndroidPermissions) {
        this.androidPermissions.checkPermission(this.androidPermissions.PERMISSION.INTERNET).then(
            result => console.log('Has permission?', result.hasPermission),
            err => this.androidPermissions.requestPermission(this.androidPermissions.PERMISSION.INTERNET)
        );
    }
}

The target device (device and emulator in AVD manager) has API 22 (Android 5.1).

config.xml

<access origin="*" />
<preference name="android-minSdkVersion" value="19" />
<plugin name="cordova-plugin-android-permissions" spec="1.0.0" />
<engine name="android" spec="^7.1.1" />

The last one (engine name) is probably for the cordova-android version and does not have to be 5.1. In package.json is under dependencies "cordova-android": "^7.1.1".

...both files includes (not written by hand):

<uses-permission android:name="android.permission.INTERNET" />

It is not a CORS problem. The REST API runs on a different server than the web browser and it works with the web browser.

I think I did everything. Is something missing or wrong?

What do you have to do to have Ionic (cordova) Internet access?

[UPDATE] The app info shows me the permissions that the app has full network access. Now I'm at a loss.

In the API, I log every request at boot time. A request of the app from the device does not arrive. The app in the browser arrives.

It was a CORS issue, but not on the API side, but on the client side.

In the config.xml <preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" /> solves my problem.

Take a look at github ionic-team issue

For me it was Android 5.1 & 8.0.
