看了一些博客，一般介紹的線程是browser跟render線程。但是ps |grep shell 獲取進程號，top -t |grep 進程號，你會看到的，估計跟我看到的差不多，就是這樣的嘩啦啦的一大片或者還更多。看到這麼多線程，總會先想想在什麼時候創建的，創建出來是做什麼用的。
我在platform_thread_android.c文件中SetName添加了打印，打印出線程名跟線程號，還順便打印了堆棧，看看線程是在什麼時候創建的。SetName部分代碼實現如下，設置線程名稱，也有線程號。
void PlatformThread::SetName(const std::string& name) {
ThreadIdNameManager::GetInstance()->SetName(CurrentId(), name);
tracked_objects::ThreadData::InitializeThreadContext(name);
base::debug::StackTrace().Print();
DLOG(ERROR) <<__FUNCTION__<< " CurrentId="<<CurrentId()<<" name="<<name;
......
}
如下是我打印的輸出的結果，可以看到創建了57個線程，線程的名稱也都有，這樣後續添加日誌的過程通過logcat -v threadtime
就可以打印出帶線程號的日誌，是哪個線程的操作。logcat始終是個比較笨的方法，後續有新方法了再進行更新。
爲了確認各線程是如何創建的，我在thread.cc的構造函數中添加了堆棧打印，打印出各線程創建的堆棧，也可以在platform_thread_android.cc的SetName打印出線程名跟線程號，便於後續debug追蹤。如下是我根據堆棧獲取的各線程的創建流程：
