移动端在继承Application的类中，打印崩溃信息log

import java.io.PrintWriter;
import java.io.StringWriter;
import java.text.SimpleDateFormat;
import java.util.Date;

//获取崩溃信息
        final Thread.UncaughtExceptionHandler defaultHandler = Thread.getDefaultUncaughtExceptionHandler();
        Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
            @Override
            public void uncaughtException(Thread thread, Throwable throwable) {
                //获取崩溃时的UNIX时间戳
                long timeMillis = System.currentTimeMillis();
                //时间戳转换
                StringBuilder stringBuilder = new StringBuilder(new SimpleDateFormat("yyyy/MM/dd HH:mm:ss").format(new Date(timeMillis)));
                stringBuilder.append(":\n");
                //获取错误信息
                stringBuilder.append(throwable.getMessage());

                throwable.printStackTrace(pw);
                stringBuilder.append(sw.toString());
                //拿到的错误信息

                //写入文件
                LogUtil.i("ceshi", " 程式崩溃 日志 : " + "\n" + errorLog);
                //如何处理该崩溃，下面使用默认的处理方式让APP停止运行
//                defaultHandler.uncaughtException(thread, throwable);
