我想获得整个日志(Log.d(…)),按下按钮分析我们的应用程序的某些部分(计算一些东西……).我可以通过以下代码执行此操作：

HashMap<String, Integer> hashMapToSaveStuff = new HashMap<String, Integer>();
int count= 0;
String toCount= "";
try {
        Process process = Runtime.getRuntime().exec("logcat -d");
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));
        String line;
        while ((line = bufferedReader.readLine()) != null) {
            if (line.contains("MYSTRING")) {
                toCount = line.substring(line.indexOf(":") + 1);
                if (hashMapToSaveStuff.containsKey(toCount)) {
                    count = hashMapToSaveStuff.get(toCount);
                    count++;
                } else {
                    count= 1;
                }
                hashMapToSaveStuff.put(toCount, count);
            }
        }
    } catch (Exception e) {

    }

之后,我将结果发送到我们的服务器并将其保存在数据库中.因此,我想清除所有日志,我已经发送了.尝试使用以下代码执行此操作不起作用：

try {
        Process process = Runtime.getRuntime().exec("logcat -c");
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()), 1024);
        String line = bufferedReader.readLine();
    } catch (Exception e) {

    }

我该如何清除日志？

解决方法:

这段代码过去对我有用：

Process process = new ProcessBuilder()
     .command("logcat", "-c")
     .redirectErrorStream(true)
     .start();
