android WebView各种坑

1.WebView必不可少的一句

webView.setWebViewClient(new WebViewClient());

2.http和https混合支持

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 

    webView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);

}

3.添加 Cookie

if(Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) CookieSyncManager.createInstance(context); 

 CookieManager cookieManager = CookieManager.getInstance(); 

cookieManager.setAcceptCookie(true);

cookieManager.setCookie(url, cookie);

4.删除 Cookie

CookieManager cookieManager = CookieManager.getInstance(); cookieManager.removeAllCookie();

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {

cookieManager.flush(); 

}

else{ 

CookieSyncManager.createInstance(Application.getInstance()); 

CookieSyncManager.getInstance().sync();

 }
