我试图从我的本地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);

} }

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);

}

}

但问题是localStorage总是为null,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);

}

从来没有被称为.

谁知道为什么？

谢谢
