Data not cleared on Android

I have logout function which I try to clear all storage data and they are not cleared.

logout() {
        this.storage.clear().then((data) => {
			console.log(data);
		})
    	this.storage.remove('token');
   	this.storage.remove('profile');
   	this.storage.remove('login');
};   

In fact when I debug with chrome://inspect#device I don’t see any data but they are loaded.

Ionic Storage driver: cordovaSQLiteDriver   SQLitePlugin.js:175 
OPEN database: _ionicstorage      SQLitePlugin.js:106 
new transaction is waiting for open operation     SQLitePlugin.js:179 
OPEN database: _ionicstorage - OK   SQLitePlugin.js:80 
DB opened: _ionicstorage         SQLitePlugin.js:80 

I don’t see any data. In chrome web it works but not on android.

I got it to clear now. THis is what I did. in config.xml

    <preference name="InAppBrowserStorageEnabled" value="false" />
    <platform name="android">
        <edit-config file="AndroidManifest.xml" mode="merge" target="/manifest/application">
            <application android:allowBackup="false" />
            <application android:fullBackupContent="false" />
        </edit-config>
   ...
   </platform>

and I also implemented the clear() method from ionic even tho I was removing each item already. https://ionicframework.com/docs/storage/#clear

Include android:allowBackup=“false” android:fullBackupContent=“false” in <application> section of AndroidManifest.xml
