Because you are using SDK version 28, change the following version from

implementation 'com.android.support:appcompat-v7:28.0.0-rc01'
androidTestImplementation "com.android.support:support-annotations:27.1.1"

to

implementation 'com.android.support:appcompat-v7:28.0.0'
androidTestImplementation "com.android.support:support-annotations:28.0.0"

Go to your IonicWebViewEngine.java file and change from:

import android.support.annotation.RequiresApi;

to:

import androidx.annotation.RequiresApi;
