BlockCanary界面卡顿检测

添加依赖:

  implementation  ‘com.github.markzhai:blockcanary-android:1.5.0‘

运行后会同时安装检测工具,主要检测UI线程运行卡顿现象

public class MainActivity extends AppCompatActivity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        SystemClock.sleep(1000);
    }

    }

让主界面卡顿1秒

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        BlockCanary.install(this, new AppContext()).start();

    }

    public class AppContext extends BlockCanaryContext {
        //默认卡顿阈值为1000ms
        public int provideBlockThreshold() {
            return 1000;
        }
        //输出的log
        public String providePath() {
            return "/blockcanary/";
        }
        //支持文件上传
        public void upload(File zippedFile) {
            throw new UnsupportedOperationException();

        }
        //可以在卡顿提供自定义操作
        @Override
        public void onBlock(Context context, BlockInfo blockInfo) {
            System.out.println("阻塞操作");
        }
    }
}

检测到卡顿超过1秒输出日志

<application
        android:name=".MyApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"

声明name属性
