王学岗CSDN ANR异常的监测

https://github.com/SalomonBrys/ANR-WatchDog 我们使用的是ANR-WatchDog，这是github的地址
首先引入该依赖

dependencies {
  implementation 'com.github.anrwatchdog:anrwatchdog:1.3.0'
}

其次，创建MyApplication类，调用ANRWatchDog类的start()方法

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        new ANRWatchDog().start();
    }
}

简单吧，这样就可以检测ANR异常了。
我们测试下

package com.example.test_0725;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        try {
            Thread.sleep(10000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

看下日志打印输出

上面代码虚线就是报ANR异常的地方。
