Android prints all thread information currently running

Android prints all thread information currently running

---

During the running of the APP, in what way can the information of all the threads currently running be obtained?

Go directly to the code:

    private final String TAG = "budaye";
    public void printAllThreadInfo() {
        Map<Thread, StackTraceElement[]> allStackTraces = Thread.getAllStackTraces();
        Log.d(TAG, "线程总数 = " + allStackTraces.size());
        for (Map.Entry<Thread, StackTraceElement[]> stackTrace : allStackTraces.entrySet()) {
            Thread thread = stackTrace.getKey();
            Log.d(TAG, "线程：" + thread.getName() + ", id=" + thread.getId() + ", state=" + thread.getState());
            StackTraceElement[] stack = stackTrace.getValue();
            String strStackTrace = "堆栈：";
            for (StackTraceElement stackTraceElement : stack) {
                strStackTrace += stackTraceElement.toString() + "\n";
            }
            Log.d(TAG, strStackTrace);
        }
    }
