HTML localStorage is null on Android when using webview
提问by Ali
I am trying to use localstorage from my local web APP, here is the WebView initialization part:
我正在尝试从本地 Web APP 使用 localstorage，这是 WebView 初始化部分：
static class MyWebView extends WebView
{
public MyWebView(Context context)
{
super(context);
this.getSettings().setJavaScriptEnabled(true);
//enable support for DOM Storage and Database
this.getSettings().setDatabaseEnabled(true);
this.getSettings().setDomStorageEnabled(true);
String databasePath = context.getDir("database", Context.MODE_PRIVATE).getPath();
this.getSettings().setDatabasePath(databasePath);
this.setVerticalScrollbarOverlay(true);
} }
and Here is the test app on JavaScript:
这是 JavaScript 上的测试应用程序：
function testStorage()
{
var storage = window.localStorage;
if (storage) {
try {
storage.setItem("name", "Hello World!"); //saves to the database, “key”, “value”
} catch (e) {
alert(e.message); //data wasn't successfully saved due to quota exceed so throw an error
}
document.write(storage.getItem("name")); //Hello World!
storage.removeItem('name');
}
else {
alert('Your browser does not support HTML5 localStorage. Because Storage is' + storage);
}
}
but the problem is that the localStorage is always null, I have checked the permissions and created a WebChromeClient with
但问题是 localStorage 始终为空，我检查了权限并创建了一个 WebChromeClient
@Override
public void onExceededDatabaseQuota(String url,
String databaseIdentifier,
long currentQuota,
long estimatedSize,
long totalUsedQuota,
WebStorage.QuotaUpdater quotaUpdater)
{
quotaUpdater.updateQuota(estimatedSize * 2);
}
which never gets called. Anyone knows why?
永远不会被调用。有谁知道为什么？
Thanks
谢谢
