SecurityError: DOM Exception 18 - Android Web View

If you are getting DOM Exception 18 when trying to create a WebSQL Database or when using IndexedDBShim
make sure that you define ExceededDatabaseQuota

Make sure you override onExceededDatabaseQuota

@SuppressWarnings("deprecation")
@Override
public void onExceededDatabaseQuota(String url,
String databaseIdentifier,
long quota,
long estimatedDatabaseSize,
long totalQuota,
QuotaUpdater quotaUpdater) {

quotaUpdater.updateQuota(estimatedDatabaseSize * 2);
}
