我是靠谱客的博主务实世界，这篇文章主要介绍Android 获取APP崩溃日志并写入本地，现在分享给大家，希望可以做个参考。

在Application中加入一下代码

Java：

复制代码

//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());
                stringBuilder.append("n");
                //获取堆栈信息
                StringWriter sw = new StringWriter();
                PrintWriter pw = new PrintWriter(sw);
                throwable.printStackTrace(pw);
                stringBuilder.append(sw.toString());
                //拿到的错误信息
                String errorLog = stringBuilder.toString();
                //写入文件
                writeLog(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);
            }
       });

        //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());
                stringBuilder.append("n");
                //获取堆栈信息
                StringWriter sw = new StringWriter();
                PrintWriter pw = new PrintWriter(sw);
                throwable.printStackTrace(pw);
                stringBuilder.append(sw.toString());
                //拿到的错误信息
                String errorLog = stringBuilder.toString();
                //写入文件
                writeLog(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);
            }
       });

            //写入文件

            //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)
