1：一些基本概念
a: 主线程，子线程的关系，凭什么你是主线程，我是子线程？
其实线程都是一样，只是我们指定了某一线程为主进程而已。
b: 为什么Activity.onCreate，Broadcast.onReceiver，Service.onBind等一系列方法在主线程运行呢？
通过查看以上这些方法调用方，就可以知道答案了。他们都是通过handler消息来处理的
android.app.ActivityThread.H#handleMessage
case RECEIVER:
Trace.traceBegin(Trace.TRACE_TAG_ACTIVITY_MANAGER, "broadcastReceiveComp");
handleReceiver((ReceiverData)msg.obj);
Trace.traceEnd(Trace.TRACE_TAG_ACTIVITY_MANAGER);
break;
具体流程参考：

https://blog.csdn.net/renshuguo123723/article/details/86471734
c: 想要监控咱们APP的各种事件消耗的时间，咱们就可以通过监控主线程的handler 的handleMessage消耗的时间来查看。
查看handler代码：
// android.os.Looper#loop
if (logging != null) {
logging.println(">>>>> Dispatching to " + msg.target + " " +
msg.callback + ": " + msg.what);
}
msg.target.dispatchMessage(msg); //分发消息
if (logging != null) {
logging.println("<<<<< Finished to " + msg.target + " " + msg.callback);
}
刚好这个logging对象可以自定义，然后我们重写println方法，通过比较两条消息时间差，就可以得知当前事件的执行时间。
android.os.Looper#setMessageLogging
2：ANR是啥呢？
Android系统中，ActivityManagerService(简称AMS)和WindowManagerService(简称WMS)会检测App的响应时间，如果App在特定时间无法相应屏幕触摸或键盘输入时间，或者特定事件没有处理完毕，就会出现ANR，即Application Not Responding。
3：ANR的种类，产生条件？
在某一事件后的某一时间之后，系统还未做出对应响应，就会产生ANR
| 事件 | 时间 | 关键日志 |
|---|---|---|
| 用户输入 | 5S | Input event dispatching timed out |
| 广播 | 前台10S，后台60S | Timeout of broadcast BroadcastRecord |
| 服务 | 前台10S，后台 | Timeout executing service |
| content provider | 10S | Timeout publishing content providers |
为什么是这个时间？
// ActivityTaskManagerService.java API 30
// How long we wait until we timeout on key dispatching.
public static final int KEY_DISPATCHING_TIMEOUT_MS = 5 * 1000;
// ActivityManagerService.java API 30
// How long we allow a receiver to run before giving up on it.
static final int BROADCAST_FG_TIMEOUT = 10*1000;
static final int BROADCAST_BG_TIMEOUT = 60*1000;
// ActiveServices.java API 30
// How long we wait for a service to finish executing.
static final int SERVICE_TIMEOUT = 20*1000;
// How long we wait for a service to finish executing.
static final int SERVICE_BACKGROUND_TIMEOUT = SERVICE_TIMEOUT * 10;
来看个例子，猜猜看，当我们点击button时，会产生ANR吗？：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mViewDataBinding = DataBindingUtil.setContentView(this,
R.layout.activity_main);
mViewDataBinding.button
.setOnClickListener(v -> {
Toast.makeText(this, "dianji", Toast.LENGTH_SHORT).show();
waitTime();
});
}
private void waitTime() {
long start = System.currentTimeMillis();
long end = start;
while (end - start < 8000) {
mViewDataBinding.button.setText(end + "");
end = System.currentTimeMillis();
}
}
注意事项: Input的超时机制与其他的不同，对于input来说即便某次事件执行时间超过timeout时长，只要用户后续在没有再生成输入事件，则不会触发ANR.
