WebSettings settings = webView.getSettings(); ?? settings.setJavaScriptEnabled(true); ??
settings.setJavaScriptCanOpenWindowsAutomatically(true); ?
... ?
settings.setDatabaseEnabled(true); ??
settings.setDatabasePath("/data/data/your.package.name/database_name");?

然后需要继承onExceededDatabaseQuota它在WebChromeClient 里面

public void onExceededDatabaseQuota(String url, String?
databaseIdentifier, long currentQuota, long estimatedSize, long?
totalUsedQuota, WebStorage.QuotaUpdater quotaUpdater) {?
? ? ? ? ? ? ? ? quotaUpdater.updateQuota(204801);?
}??
