AgentWeb 介绍

项目地址：https://link.jianshu.com/?t=https://github.com/Justson/AgentWeb

AgentWeb 是一个基于的 Android WebView ，极度容易使用以及功能强大的库，提供了 Android WebView 一系列的问题解决方案 ，并且轻量和极度灵活

引入
Gradle
api ‘com.just.agentweb:agentweb:4.0.3-beta’ // (必选)
api ‘com.just.agentweb:filechooser:4.0.3-beta’// (可选)
api ‘com.just.agentweb:download:4.0.3-beta’ // (可选)
api ‘com.github.Justson:Downloader:v4.0.3’// (可选)

基础用法

mAgentWeb = AgentWeb.with(this)
             .setAgentWebParent(view, new LinearLayout.LayoutParams(-1, -1))                
              .useDefaultIndicator()
              .createAgentWeb()
              .ready()
              .go("URL");

调用 Javascript 方法拼接太麻烦 ？ 请看 。

    function callByAndroid(){
               console.log("callByAndroid")
       }
mAgentWeb.getJsAccessEntrace().quickCallJs("callByAndroid");

Javascript 调 Java ?

 mAgentWeb.getJsInterfaceHolder().addJavaObject("android",new AndroidInterface(mAgentWeb,this));
  window.android.callAndroid();

事件处理

 @Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (mAgentWeb.handleKeyEvent(keyCode, event)) {    
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

跟随 Activity Or Fragment 生命周期 ， 释放 CPU 更省电 。

  @Override
    protected void onPause() {
        mAgentWeb.getWebLifeCycle().onPause(); 
        super.onPause();
    }
    @Override
    protected void onResume() {
        mAgentWeb.getWebLifeCycle().onResume();
        super.onResume();
    }
    @Override
    public void onDestroyView() {
        mAgentWeb.getWebLifeCycle().onDestroy();
        super.onDestroyView();
    }    

全屏视频播放
如果你的应用需要用到视频 ， 那么请你在使用 AgentWeb 的 Activity 对应的清单文件里加入如下配置

  android:hardwareAccelerated="true"
    android:configChanges="orientation|screenSize"

定位
AgentWeb 是默认允许定位的 ，如果你需要该功能 ， 请在你的 AndroidManifest 文件里面加入如下权限

WebChromeClient 与 WebViewClient

           AgentWeb.with(this)
                .setAgentWebParent(mLinearLayout,new LinearLayout.LayoutParams(-1,-1) )
                .useDefaultIndicator()
                .setReceivedTitleCallback(mCallback)
                .setWebChromeClient(mWebChromeClient)
                .setWebViewClient(mWebViewClient)
                .setSecutityType(AgentWeb.SecurityType.strict)
                .createAgentWeb()
                .ready()
                .go(getUrl());
   private WebViewClient mWebViewClient=new WebViewClient(){
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
           //do you  work
        }
    };
   private WebChromeClient mWebChromeClient=new WebChromeClient(){
        @Override
        public void onProgressChanged(WebView view, int newProgress) {
            //do you work
        }
    };                

返回上一页

if (!mAgentWeb.back()){
       AgentWebFragment.this.getActivity().finish();
}

获取 WebView

mAgentWeb.getWebCreator().getWebView();

文件下载监听
protected DownloadListenerAdapter mDownloadListenerAdapter = new DownloadListenerAdapter() {

	@Override
	public boolean onStart(String url, String userAgent, String contentDisposition, String mimetype, long contentLength, AgentWebDownloader.Extra extra) {
		extra.setOpenBreakPointDownload(true)
				.setIcon(R.drawable.ic_file_download_black_24dp)
				.setConnectTimeOut(6000)
				.setBlockMaxTime(2000)
				.setDownloadTimeOut(60L * 5L * 1000L)
				.setAutoOpen(true)
				.setForceDownload(false);
		return false;
	}


	@Override
	public void onBindService(String url, DownloadingService downloadingService) {
		super.onBindService(url, downloadingService);
		mDownloadingService = downloadingService;
		LogUtils.i(TAG, "onBindService:" + url + "  DownloadingService:" + downloadingService);
	}


	@Override
	public void onUnbindService(String url, DownloadingService downloadingService) {
		super.onUnbindService(url, downloadingService);
		mDownloadingService = null;
		LogUtils.i(TAG, "onUnbindService:" + url);
	}


	@Override
	public void onProgress(String url, long loaded, long length, long usedTime) {
		int mProgress = (int) ((loaded) / Float.valueOf(length) * 100);
		LogUtils.i(TAG, "onProgress:" + mProgress);
		super.onProgress(url, loaded, length, usedTime);
	}


	@Override
	public boolean onResult(String path, String url, Throwable throwable) {
		if (null == throwable) { 
			//do you work
		} else {

		}
		return false; 
	}
};

查看 Cookies

String cookies=AgentWebConfig.getCookiesByUrl(targetUrl);

同步 Cookie

AgentWebConfig.syncCookie("http://www.jd.com","ID=XXXX");
MiddlewareWebChromeBase 支持多个 WebChromeClient

清空缓存

AgentWebConfig.clearDiskCache(this.getContext());

权限拦截

protected PermissionInterceptor mPermissionInterceptor = new PermissionInterceptor() {

        @Override
        public boolean intercept(String url, String[] permissions, String action) {
            Log.i(TAG, "url:" + url + "  permission:" + permissions + " action:" + action);
            return false;
        }
    };

AgentWeb 完整用法

 mAgentWeb = AgentWeb.with(this)
            .setAgentWebParent((LinearLayout) view, new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT))
            .useDefaultIndicator(-1, 3)
            .setAgentWebWebSettings(getSettings())
            .setWebViewClient(mWebViewClient)
            .setWebChromeClient(mWebChromeClient)
            .setPermissionInterceptor(mPermissionInterceptor) 
            .setSecurityType(AgentWeb.SecurityType.STRICT_CHECK) 
            .setAgentWebUIController(new UIController(getActivity())) 
            .setMainFrameErrorView(R.layout.agentweb_error_page, -1)
            .useMiddlewareWebChrome(getMiddlewareWebChrome())
            .useMiddlewareWebClient(getMiddlewareWebClient()) 
            .setOpenOtherPageWays(DefaultWebClient.OpenOtherPageWays.DISALLOW)
            .interceptUnkownUrl() 
            .createAgentWeb()
            .ready()
            .go(getUrl()); 

AgentWeb 所需要的权限(在你工程中根据需求选择加入权限)

AgentWeb 所依赖的库

  compile "com.android.support:design:${SUPPORT_LIB_VERSION}" // (3.0.0开始该库可选)
    compile "com.android.support:support-v4:${SUPPORT_LIB_VERSION}"
    SUPPORT_LIB_VERSION=27.0.2(该值会更新)
