webview的http错误码404等接收不了

http://www.lai18.com/content/1513532.html这个文章是没有用的。要webivew接收http的错误码
@OverRide
public void onReceivedHttpError(WebView view, WebResourceRequest request, WebResourceResponse errorResponse) {
Log.d(LOG_TAG, "onReceivedHttpError: "+errorResponse.getStatusCode()+" "+errorResponse.getReasonPhrase());
super.onReceivedHttpError(view, request, errorResponse);
}

接收不了ssl的即https的错误码
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {

Http和https错误码的理解

http的返回码http://w3school.com.cn/tags/html_ref_httpmessages.asp
http://blog.sina.com.cn/s/blog_59b052fa0100it74.html
https://developer.mozilla.org/en-US/docs/Web/HTTP/Status
假如我们定义了537不属于标准（已知的）的http返回码，也会返回response中的537,536等等只要属于5xx

但是假如是https请求会得不到response，要try catch得到io异常里面的错误信息
E/IOException: java.io.IOException: Unexpected response code for CONNECT: 537

android studio如何分模块新建子包

我们常常新建了一个project的package name 是com.xxx.application.假如我们想分模块建立子包，在目录模式下面，例如在com.xxx.application.login登录模块后面直接new package 三个model ，view，presenter。必须切换目录模式为android才新建子包。这样看起来就不会login.view.model.presenter在一起。或者关掉 flatten package不是平铺。。

获取BaseActivity的view

View rootView = ((ViewGroup) (getWindow().getDecorView().findViewById(android.R.id.content))).getChildAt(0);或者ViewGroup content =(ViewGroup)findViewById(android.R.id.content);

gradel学习事项

Android Studio是用gradle来构建项目的，有很多环境方面的文件都不需要增加到SVN版本库。

以下为列出不需要增加到版本库的文件：

  1. .idea 文件夹，此文件夹是用来保存开发工具的设置信息。

  2. .gradle 文件夹，此文件夹是用来保存gradle的依赖信息。

  3. 所有的 build 文件夹，build文件夹是用来保存编译后的文件目录。

  4. 所有的 .iml 文件，是用来保存开发工具信息。

  5. local.properties 文件，是用来保存项目依赖信息

Android手机run apk遇到的问题

  1. 前提插入usb选择usb模式是mtp不是充电模式。windows要安装驱动对应厂商的。小米手机USB安装apk要打开开发者模式中的USB安装 还要申请小米账号是*****
    2.小米手机尽量关闭instant run 还要关闭MIUI优化
