我的webview有問(wèn)題，它可能通過(guò)HTML5應(yīng)用程序訪問(wèn)localStorage 。test.html文件通知我瀏覽器（即webview）不支持本地存儲(chǔ)。如果您有任何建議。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; } }}

在API級(jí)別19中已棄用setDatabasePath（）方法。建議您使用如下存儲(chǔ)區(qū)域設(shè)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/");
}

適用于我的Android 4.2.2的解決方案，已使用構(gòu)建目標(biāo)Android 4.4W進(jìn)行了編譯：
WebSettings settings = webView.getSettings();
settings.setDomStorageEnabled(true);
settings.setDatabaseEnabled(true);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
File databasePath = getDatabasePath("yourDbName");
settings.setDatabasePath(databasePath.getPath());
}
