如何检测自己的APP是否卡

通过Choreographer的回调次数检测当前时刻运行的流畅度，原理参看：http://bugly.qq.com/blog/?p=166

正常一秒会有60次的回调

import android.app.Activity;

import android.util.Log;

import android.view.Choreographer;

public class CheckActivity extends Activity implements Choreographer.FrameCallback {

    private long mTime = 0;

    private long mNumber = 0;

    @Override

    public void doFrame(long frameTimeNanos) {

        if (System.currentTimeMillis() - mTime >= 1000) {

            Log.d("CheckActivity", "doFrame " + mNumber);

            mNumber = 0;

            mTime = System.currentTimeMillis();

        } else {

            mNumber++;

        }

        Choreographer.getInstance().postFrameCallback(this);

    }

    @Override

    protected void onStart() {

        super.onStart();

        Choreographer.getInstance().postFrameCallback(this);

    }

    @Override

    protected void onStop() {

        super.onStop();

        Choreographer.getInstance().removeFrameCallback(this);

    }

}
