【Android】webview强制Crash后再自恢复设计

模拟WebView 崩溃Crash

官方给出的方式是：

访问：chrome://crash 或者 chrome://inducebrowsercrashforrealz

chrome://crash

chrome://inducebrowsercrashforrealz

捕获webview崩溃

public class MyWebViewClient extends WebViewClient {


        @Override
        public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
            super.onReceivedError(view, request, error);
            Log.e(TAG,"onReceivedError called! code=" + error.getErrorCode()+" ,desc="+error.getDescription());
        }

        @Override
        public boolean onRenderProcessGone(WebView view, RenderProcessGoneDetail detail) {
            Log.e(TAG,"onRenderProcessGone called!");
            recreateWebViewAndReload(view);
            return true;
        }

        @Nullable
        @Override
        public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {

            return super.shouldInterceptRequest(view, request);
        }

    }

使用上

  webView.setWebViewClient(new MyWebViewClient());

webview崩溃后会停顿一段时间触发onRenderProcessGone；后续逻辑就可以在这里进行webview恢复了。

webView恢复方式

 private void recreateWebViewAndReload(WebView view) {
        if(view==null||view.getParent()==null|| !(view.getParent() instanceof ViewGroup)){
            Log.i(TAG,"应用需要重启");
            return;
        }
        ViewGroup parent= (ViewGroup) view.getParent();
        int index=parent.indexOfChild(view);
        ViewGroup.LayoutParams lp= view.getLayoutParams();

        parent.removeView(view);
        view.destroy();
        WebView webViewNew=new WebView(parent.getContext());
        webViewNew.setLayoutParams(lp);
        parent.addView(webViewNew,index);
        webViewNew.loadUrl(url);
        webView=webViewNew;
        webView.setWebViewClient(new MyWebViewClient());

    }

推荐理由

postman在国内使用已经越来越困难：

1、登录问题严重

2、Mock功能服务基本没法使用

3、版本更新功能已很匮乏

4、某些外力因素导致postman以后能否使用风险较大

5、postman会导致电脑卡顿，而且使用的功能越多越慢，尤其是win电脑，太让人郁闷了

出于以上考虑因此笔者自己开发了一款api调试开发工具SmartApi，满足基本日常开发调试api需求

是的，兄弟们，我还是建立了自己的官网！需要下载的大佬直接去官网下载就可以了蛤，顺便看看官网介绍
