ذخیره کردن اطلاعات وب ویو

مثل این باشه؟ ولی چطوری کش خود سیستم غیرفعال شه؟

webView = (WebView) rootView.findViewById(R.id.webView1);
        webView.getSettings().setAppCacheMaxSize(1024*1024*8);
		webView.getSettings().setAppCachePath( getActivity().getCacheDir().getAbsolutePath() );
		webView.getSettings().setAllowFileAccess( true );
		webView.getSettings().setAppCacheEnabled( true );
		webView.getSettings().setJavaScriptEnabled( true );
		webView.getSettings().setCacheMode( WebSettings.LOAD_DEFAULT ); // load online by default
		webView.loadUrl( "http://www.google.com" );

محمد حسین جان من گیر کردم . لطف می کنی بگی data رو چکار کنم که بخونه ؟

   mWebView = (WebView) findViewById(R.id.webviewMain);
        WebSettings settings = mWebView.getSettings();
        settings.setJavaScriptEnabled(true);
        mWebView.getSettings().setAppCacheEnabled( false );

        if (enableCache) {
            saveToCache(System.currentTimeMillis(), data);
        }
        
       
        if (enableCache) {
        String data = null;
            data = readFromCache();
        }

        if (data == null) {
        	
        	 mWebView.loadUrl(URL);
        	
          
        } 
      
         
    }
    

    private void saveToCache(long when, String data) {
        ObjectOutputStream outputStream = null;
        try {
            outputStream = new ObjectOutputStream(new FileOutputStream(cacheDir + "/" + cacheFileName));
            outputStream.writeLong(when);
            outputStream.writeInt(data.length());
            outputStream.write(data.getBytes());
        }
        catch (StreamCorruptedException e) {
            e.printStackTrace();
        }
        catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (outputStream != null) {
                try {
                    outputStream.flush();
                }
                catch (IOException e) {

                }
            }
        }
    }

    
    private String readFromCache() {
        ObjectInputStream inputStream = null;
        try {
            inputStream = new ObjectInputStream(new FileInputStream(cacheDir + "/" + cacheFileName));

            long when = inputStream.readLong();
            long now = System.currentTimeMillis();
            if (now - when > cacheExpireTime * 1000) {
                new File(cacheDir + "/cache.dat").delete();
                return null;
            }

            int bytesLength = inputStream.readInt();
            byte[] buffer = new byte[bytesLength];
            inputStream.readFully(buffer, 0, bytesLength);
            String output = new String(buffer);
            return output;
        }
        catch (StreamCorruptedException e) {

                    inputStream.close();
                }

با این کد میتونید سورس HTML رو در یک String بریزید و داخل وب ویو نمایش بدید :

         webview.loadData(html_value,"text/html","UTF-8");

محمد جان من نمی تونم درستش کنم ، امکانش هست این کد رو کامل کنی تا درست بشه؟

 class MyJavaScriptInterface {

		@SuppressWarnings("unused")
		public void showHTML(String html) {

		}
	}

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		browser = (WebView) findViewById(R.id.webkit);
		browser.getSettings().setAppCacheEnabled(false);
		browser.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
		browser.getSettings().setJavaScriptEnabled(true);
		browser.addJavascriptInterface(new MyJavaScriptInterface(), "HTMLOUT");
		browser.loadUrl("http://192.168.1.1/android/html/aboutus/about.html");

	}




	private void saveToCache(long when, String data) {
		ObjectOutputStream outputStream = null;
		try {
			outputStream = new ObjectOutputStream(new FileOutputStream(cacheDir
					+ "/" + cacheFileName));
			outputStream.writeLong(when);
			outputStream.writeInt(data.length());

				}
				try {

				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
	}

	private String readFromCache() {
		ObjectInputStream inputStream = null;
		try {
			inputStream = new ObjectInputStream(new FileInputStream(cacheDir

			long when = inputStream.readLong();
			long now = System.currentTimeMillis();
			if (now - when > cacheExpireTime * 1000) {
				new File(cacheDir + "/cache.dat").delete();
				return null;
			}

			int bytesLength = inputStream.readInt();
			byte[] buffer = new byte[bytesLength];
			inputStream.readFully(buffer, 0, bytesLength);
			String output = new String(buffer);
			return output;

این کد وب ویو :

هر کسی دوست داشت استفاده کنه ...

 ConnectionDetector cd;
	WebView engine;
