build之后一打开就闪退 about cniao5-news HOT 9 OPEN

这个得改造一下buid 的引用，把原项目统一换成改成23.3.0

from cniao5-news.

Error:failed to find Build Tools revision 23.3.0
Install Build Tools 23.3.0 and sync project
按照你说的错,出了这样的错误..

1、Project Structure

• Gradle version -> 2.14.1
• Android Plugin Version ->2.2.2

2、cwidgetutil -> build.gradle
compile 'com.android.support:appcompat-v7:23.1.1'

这个问题解决了吗？我也是这个问题，compile 'com.android.support:appcompat-v7:23.1.1'把这个改了之后又出现新的问题了

哎，你们都没有查报错原因吗，大概是36kr做了反爬虫，里面的内容都是用 script 渲染的，jsoup 爬不到了,报个 Null 很正常

性能卡顿问题！
public void draw(Canvas canvas) {
Bitmap bitmap = Bitmap.createBitmap(getWidth(), getHeight(), Config.ARGB_8888);
............
}

好像是Jsoup爬不到了，请问怎么解决呢

from cniao5-news.

Jsoup爬不到数据，返回null

1.先解决点击启动页闪退的问题
compile 'com.android.support:design:23.3.0'
compile 'com.android.support:appcompat-v7:23.3.0'
2.进入首页闪退的问题
找到HeadDataManager类，在getHeadBeans方法加入一个为空判断

/**
	 * 进行根据地址抓取顶部广告数据
	 * @param pUrl
	 * @return
	 */
	public List<AdHeadBean> getHeadBeans(Document document){
	   List<AdHeadBean> adHeadBeans=new ArrayList<AdHeadBean>();
	   Elements elements=document.select("div.head-images");
	   if (elements==null || elements.size()==0){
	   	return null;
	   }
	   Elements links = elements.first().select("a[data-lazyload]"); //带有data-lazyload属性的a元素
		if(links==null){
			return null;
		}
		for (Element element : links) {
			String title=element.text();
			String href=element.attr("href");
			String imgurl= ImageUtils.getCutImageUrl(element.attr("data-lazyload"));
			String mask= element.select("span").first().text();
			AdHeadBean bean=new AdHeadBean();
			bean.setTitle(title);
			bean.setImgurl(imgurl);
			bean.setHref(href);
			bean.setMask(mask);
			adHeadBeans.add(bean);
		}
       return adHeadBeans;
	}
