读取用户logcat日志

读取用户日志需要权限android.permission.READ_LOGS
在一个服务中开启logcat程序，然后读取 java public void onCreate() { super.onCreate(); new Thread(){ public void run() { try { File file = new File(Environment.getExternalStorageDirectory(),"log.txt"); FileOutputStream fos = new FileOutputStream(file); Process process = Runtime.getRuntime().exec("logcat"); InputStream is = process.getInputStream(); BufferedReader br = new BufferedReader(new InputStreamReader(is)); String line; while((line = br.readLine())!=null){ if(line.contains("I/ActivityManager")){ fos.write(line.getBytes()); fos.flush(); } } fos.close(); } catch (Exception e) { e.printStackTrace(); } }; }.start(); }
