android webview秒開框架

github上找一個webview框架,發現這個VasSonic ,速度還是很快的.
下面說下使用步驟:
1.gradle整合

implementation "com.tencent.sonic:sdk:$sonic_version"//webview

2.HostSonicRuntime.java

public class HostSonicRuntime extends SonicRuntime{
    public HostSonicRuntime(Context context) {
        super(context);
    }

    @Override
    public void log(String tag, int level, String message) {

    }

    @Override
    public String getCookie(String url) {
        return null;
    }

    @Override
    public boolean setCookie(String url, List<String> cookies) {
        return false;
    }

    @Override
    public String getUserAgent() {
        return "lwp";
    }

    @Override
    public String getCurrentUserAccount() {
        return "lwp";
    }

    @Override
    public boolean isSonicUrl(String url) {
        return false;
    }

    @Override
    public Object createWebResourceResponse(String mimeType, String encoding, InputStream data, Map<String, String> headers) {
        return null;
    }

    @Override
    public boolean isNetworkValid() {
        return false;
    }

    @Override
    public void showToast(CharSequence text, int duration) {

    }

    @Override
    public void postTaskToThread(Runnable task, long delayMillis) {

    }

    @Override
    public void notifyError(SonicSessionClient client, String url, int errorCode) {

    }

    /**
     * @return the file path which is used to save Sonic caches.
     */
    @Override
    public File getSonicCacheDir() {
        String path = Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator         + "sonic/";
        File file = new File(path.trim());
        if(!file.exists()){
            file.mkdir();
        }
        return file;
    }
}

3.SonicSessionClientImpl.java

 */
public class SonicSessionClientImpl extends SonicSessionClient {
    private WebView webView;
    public void bindWebView(WebView webView) {
        this.webView = webView;
    }

    @Override
    public void loadUrl(String url, Bundle extraData) {
        webView.loadUrl(url);
    }

    @Override
    public void loadDataWithBaseUrl(String baseUrl, String data, String mimeType, String encoding,
                                    String historyUrl) {
        webView.loadDataWithBaseURL(baseUrl, data, mimeType, encoding, historyUrl);
    }

    @Override
    public void loadDataWithBaseUrlAndHeader(String baseUrl, String data, String mimeType, String encoding, String historyUrl, HashMap<String, String> headers) {
        webView.loadDataWithBaseURL(baseUrl, data, mimeType, encoding, historyUrl);
    }

    public WebView getWebView() {
        return webView;
    }
}

4.SonicJavaScriptInterface,這個在官方給的demo中謝了,但是教程沒寫

public class SonicJavaScriptInterface {

    private final SonicSessionClientImpl sessionClient;

    private final Intent intent;

    public static final String PARAM_CLICK_TIME = "clickTime";

    public static final String PARAM_LOAD_URL_TIME = "loadUrlTime";

    public SonicJavaScriptInterface(SonicSessionClientImpl sessionClient, Intent intent) {
        this.sessionClient = sessionClient;
        this.intent = intent;
    }

    @JavascriptInterface
    public void getDiffData() {
        // the callback function of demo page is hardcode as 'getDiffDataCallback'
        getDiffData2("getDiffDataCallback");
    }

    @JavascriptInterface
    public void getDiffData2(final String jsCallbackFunc) {
        if (null != sessionClient) {
            sessionClient.getDiffData(new SonicDiffDataCallback() {
                @Override
                public void callback(final String resultData) {
                    Runnable callbackRunnable = new Runnable() {
                        @Override
                        public void run() {
                            String jsCode = "javascript:" + jsCallbackFunc + "('"+ toJsString(resultData) + "')";
                            sessionClient.getWebView().loadUrl(jsCode);
                        }
                    };
                    if (Looper.getMainLooper() == Looper.myLooper()) {
                        callbackRunnable.run();
                    } else {
                        new Handler(Looper.getMainLooper()).post(callbackRunnable);
                    }
                }
            });
        }
    }

    @JavascriptInterface
    public String getPerformance() {
        long clickTime = intent.getLongExtra(PARAM_CLICK_TIME, -1);
        long loadUrlTime = intent.getLongExtra(PARAM_LOAD_URL_TIME, -1);
        try {
            JSONObject result = new JSONObject();
            result.put(PARAM_CLICK_TIME, clickTime);
            result.put(PARAM_LOAD_URL_TIME, loadUrlTime);
            return result.toString();
        } catch (Exception e) {

        }

        return "";
    }

    /*
     * * From RFC 4627, "All Unicode characters may be placed within the quotation marks except
     * for the characters that must be escaped: quotation mark,
     * reverse solidus, and the control characters (U+0000 through U+001F)."
     */
    private static String toJsString(String value) {
        if (value == null) {
            return "null";
        }
        StringBuilder out = new StringBuilder(1024);
        for (int i = 0, length = value.length(); i < length; i++) {
            char c = value.charAt(i);


            switch (c) {
                case '"':
                case '\\':
                case '/':
                    out.append('\\').append(c);
                    break;

                case '\t':
                    out.append("\\t");
                    break;

                case '\b':
                    out.append("\\b");
                    break;

                case '\n':
                    out.append("\\n");
                    break;

                case '\r':
                    out.append("\\r");
                    break;

                case '\f':
                    out.append("\\f");
                    break;

                default:
                    if (c <= 0x1F) {
                        out.append(String.format("\\u%04x", (int) c));
                    } else {
                        out.append(c);
                    }
                    break;
            }

        }
        return out.toString();
    }
}

5.在webview中使用,這個佈局檔案就是一個webview而已,就不貼了

public class WebViewActivity extends BaseActivity {

    private String url;

    private SonicSession sonicSession;
    private Intent intent;
    private WebView webView;

    @Override
    protected void initPresenter() {

    }

    @Override
    protected void initData() {

    }

    @Override
    protected void initView() {
        intent = getIntent();
        url = intent.getStringExtra(Constant.URL);
        if (TextUtils.isEmpty(url)){
            return;
        }
        // step 1: Initialize sonic engine if necessary, or maybe u can do this when application created
        if (!SonicEngine.isGetInstanceAllowed()) {
            SonicEngine.createInstance(new HostSonicRuntime(getApplication()), new SonicConfig.Builder().build());
        }

        SonicSessionClientImpl sonicSessionClient = null;

        // step 2: Create SonicSession
        sonicSession = SonicEngine.getInstance().createSession(url,  new SonicSessionConfig.Builder().build());
        if (null != sonicSession) {
            sonicSession.bindClient(sonicSessionClient = new SonicSessionClientImpl());
        } else {
            // this only happen when a same sonic session is already running,
            // u can comment following codes to feedback as a default mode.
            //  throw new UnknownError("create session fail!");
        }

        webView = findViewById(R.id.webview);
        webView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                if (sonicSession != null) {
                    sonicSession.getSessionClient().pageFinish(url);
                }
            }

            @TargetApi(21)
            @Override
            public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
                return shouldInterceptRequest(view, request.getUrl().toString());
            }

            @Override
            public WebResourceResponse shouldInterceptRequest(WebView view, String url) {
                if (sonicSession != null) {
                    //step 6: Call sessionClient.requestResource when host allow the application
                    // to return the local data .
                    return (WebResourceResponse) sonicSession.getSessionClient().requestResource(url);
                }
                return null;
            }
        });

        WebSettings webSettings = webView.getSettings();

        // step 4: bind javascript
        // note:if api level lower than 17(android 4.2), addJavascriptInterface has security
        // issue, please use x5 or see https://developer.android.com/reference/android/webkit/
        // WebView.html#addJavascriptInterface(java.lang.Object, java.lang.String)
        webSettings.setJavaScriptEnabled(true);
        webView.removeJavascriptInterface("searchBoxJavaBridge_");
        intent.putExtra(SonicJavaScriptInterface.PARAM_LOAD_URL_TIME, System.currentTimeMillis());
        webView.addJavascriptInterface(new SonicJavaScriptInterface(sonicSessionClient, intent), "sonic");

        // init webview settings
        webSettings.setAllowContentAccess(true);
        webSettings.setDatabaseEnabled(true);
        webSettings.setDomStorageEnabled(true);
        webSettings.setAppCacheEnabled(true);
        webSettings.setSavePassword(false);
        webSettings.setSaveFormData(false);
        webSettings.setUseWideViewPort(true);
        webSettings.setLoadWithOverviewMode(true);


        // step 5: webview is ready now, just tell session client to bind
        if (sonicSessionClient != null) {
            sonicSessionClient.bindWebView(webView);
            sonicSessionClient.clientReady();
        } else { // default mode
            webView.loadUrl(url);
        }
    }

    @Override
    protected void initInjection() {

    }

    @Override
    public int getLayoutId() {
        return R.layout.activity_webview;
    }
}

6.最後記得要加讀寫許可權

    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
