您需要在運行時檢查這些功能(以及可能打開它們自己),可以通過以下代碼複製this SO answer

wv = (WebView) findViewById(R.id.webview); 
    WebSettings ws = wv.getSettings(); 

    ws.setJavaScriptEnabled(true); 
    ws.setAllowFileAccess(true); 


    if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.ECLAIR) { 
     try { 
      Log.d(TAG, "Enabling HTML5-Features"); 
      Method m1 = WebSettings.class.getMethod("setDomStorageEnabled", new Class[]{Boolean.TYPE}); 
      m1.invoke(ws, Boolean.TRUE); 

      Method m2 = WebSettings.class.getMethod("setDatabaseEnabled", new Class[]{Boolean.TYPE}); 
      m2.invoke(ws, Boolean.TRUE); 

      Method m3 = WebSettings.class.getMethod("setDatabasePath", new Class[]{String.class}); 
      m3.invoke(ws, "/data/data/" + getPackageName() + "/databases/"); 

      Method m4 = WebSettings.class.getMethod("setAppCacheMaxSize", new Class[]{Long.TYPE}); 
      m4.invoke(ws, 1024*1024*8); 

      Method m5 = WebSettings.class.getMethod("setAppCachePath", new Class[]{String.class}); 
      m5.invoke(ws, "/data/data/" + getPackageName() + "/cache/"); 

      Method m6 = WebSettings.class.getMethod("setAppCacheEnabled", new Class[]{Boolean.TYPE}); 
      m6.invoke(ws, Boolean.TRUE); 

      Log.d(TAG, "Enabled HTML5-Features"); 
     } 
     catch (NoSuchMethodException e) { 
      Log.e(TAG, "Reflection fail", e); 
     } 
     catch (InvocationTargetException e) { 
      Log.e(TAG, "Reflection fail", e); 
     } 
     catch (IllegalAccessException e) { 
      Log.e(TAG, "Reflection fail", e); 
     } 
    }
