在WebView安卓系统中缓存到本地存储

WebView webView = findViewById(R.id.webview);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);

webSettings.setDomStorageEnabled(true);

webView.loadUrl("https://example.com");

// 存储数据
localStorage.setItem('key', 'value');

// 读取数据
var value = localStorage.getItem('key');
console.log(value); // 输出: value

// 删除数据
localStorage.removeItem('key');

// 清除所有数据
localStorage.clear();

webSettings.setCacheMode(WebSettings.LOAD_DEFAULT);

File cacheDir = getApplicationContext().getCacheDir();
webSettings.setAppCachePath(cacheDir.getAbsolutePath());
webSettings.setAppCacheEnabled(true);

        // 加载网页
