Android webview&localStorage

我有一个webview可以通过HTML5应用程序访问localStorage的问题。 test.html文件告诉我本地存储不受我的浏览器支持(即webview )。 如果您有任何建议..

package com.test.HelloWebView; 
import android.app.Activity; 
import android.content.Context; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.KeyEvent; 
import android.webkit.WebChromeClient; 
import android.webkit.WebSettings; 
import android.webkit.WebStorage; 
import android.webkit.WebView; 
import android.webkit.WebViewClient; 
public class HelloWebView extends Activity { 
WebView webview; 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    webview = (WebView) findViewById(R.id.webview); 
    webview.getSettings().setJavaScriptEnabled(true); 
    webview.setWebViewClient(new HelloWebViewClient()); 
    webview.loadUrl("file:///android_asset/test.html"); 
    WebSettings settings = webview.getSettings(); 
    settings.setJavaScriptEnabled(true); 
    settings.setDatabaseEnabled(true); 
    String databasePath = this.getApplicationContext().getDir("database", Context.MODE_PRIVATE).getPath(); 
    settings.setDatabasePath(databasePath);
    webview.setWebChromeClient(new WebChromeClient() { 
    public void onExceededDatabaseQuota(String url, String databaseIdentifier, long currentQuota, long estimatedSize, long totalUsedQuota, WebStorage.QuotaUpdater quotaUpdater) { 
            quotaUpdater.updateQuota(5 * 1024 * 1024); 
        } 
    }); 
} 
public boolean onKeyDown(int keyCode, KeyEvent event) { 
    if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) { 
        webview.goBack(); 
        return true; 
    } 
    return super.onKeyDown(keyCode, event); 
} 
private class HelloWebViewClient extends WebViewClient { 
    public boolean shouldOverrideUrlLoading(WebView view, String url) { 
        view.loadUrl(url); 
        return true; 
    } 
}
} 

以下遗失:

settings.setDomStorageEnabled(true);

setDatabasePath()方法已在API级别19中弃用。我建议您使用如下所示的存储区域设置:

webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setDatabaseEnabled(true);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
    webView.getSettings().setDatabasePath("/data/data/" + webView.getContext().getPackageName() + "/databases/");
}

应用程序重新启动后,我也遇到数据丢失的问题。 添加这个帮助:

webView.getSettings().setDatabasePath("/data/data/" + webView.getContext().getPackageName() + "/databases/");
