Error: Realm at path ‘/data/user/0/com.drug/files/drugApp.realm’ already opened on current thread with different schema.

To solve this error you need to close Realm instance like below code example:-

export const insertNewContact = newcontact => new Promise((resolve,reject) => {
	Realm.open(databaseOptions).then(realm=>{
		realm.write(() => {
			console.log(newcontact);
		    realm.create(CONTACT_SCHEMA, newcontact);
		    resolve(newcontact);
            realm.close();
		});
	}).catch((error) => reject(error));
});
