如何获取 android 的系统日志
公司要调试产品，想要监视试用品的logcat ,捕获本机产生的日志，发送到服务器上
折腾了一天，基本上做好
现在来看代码
读取日志需要的权限
<uses-permission android:name="android.permission.READ_LOGS"/>
主要代码
package mt.fzgh;import java.io.BufferedReader;import java.io.InputStreamReader;import java.util.ArrayList;public class MyLog{ public static class MLog //静态类 { public static void getLog() { System.out.println("--------func start--------"); // 方法启动 try { ArrayList<String> cmdLine=new ArrayList<String>(); //设置命令 logcat -d 读取日志 cmdLine.add("logcat"); cmdLine.add("-d"); ArrayList<String> clearLog=new ArrayList<String>(); //设置命令 logcat -c 清除日志 clearLog.add("logcat"); clearLog.add("-c"); Process process=Runtime.getRuntime().exec(cmdLine.toArray(new String[cmdLine.size()])); //捕获日志 BufferedReader bufferedReader=new BufferedReader(new InputStreamReader(process.getInputStream())); //将捕获内容转换为BufferedReader // Runtime.runFinalizersOnExit(true); String str=null; while((str=bufferedReader.readLine())!=null) //开始读取日志，每次读取一行 { Runtime.getRuntime().exec(clearLog.toArray(new String[clearLog.size()])); //清理日志....这里至关重要，不清理的话，任何操作都将产生新的日志，代码进入死循环，直到bufferreader满 System.out.println(str); //输出，在logcat中查看效果，也可以是其他操作，比如发送给服务器.. } if(str==null) { System.out.println("-- is null --"); } } catch(Exception e) { e.printStackTrace(); } System.out.println("--------func end--------"); } }}
这里比较令人纠结的一点就是日志的清理 logcat -c 如果不加入 清理 在buffer满为止，代码自身能够迭代6~7次....
接下来看看结果 日志比较长....一般都这样..原日志用蓝色，捕获并输出对比部分为红色
