Error after packed app

Open your file platforms/android/app/src/main/AndroidManifest.xml and add:

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

And run debug again

Debug on Physical Android Devices

1. Activate Developer Options and open USB Debugging
2. Connect your android to PC
3. Start ionic server: ionic serve
4. Chrome/Edge access chrome://inspect/#devices
   • You will see your device listed but you won’t able to see inspect link
5. Open the app in your android
   • You will see inspect link now
6. Click inspect then you can debug it with source
