我只是想获得的时间用于每项活动的号码。 所以很简单的方法，我认为是增加了计数的活动它启动时。但是，我怎么能得到这些信息？

I just want to get numbers of times to be used for each Activity. So the very straightforward method I thought is increasing the count for an Activity when it was started. But how can I get the information?

感谢您的帮助很大！

推荐答案

最后，我找到了一个解决方案，使用IActivityWatcher和ActivityManagerNative，并建立在源$ C ​​$ C。

Finally, I found a solution, use IActivityWatcher and ActivityManagerNative, and build in source code.

感谢T3Roar非常多，我只是按照你的线索，找到这一点。

Thank T3Roar very much, I just follow your clue to find this.

下面的示例code：

package zouyu.sample.activitymonitor;

import android.app.Activity;
import android.app.ActivityManagerNative;
import android.app.IActivityWatcher;
import android.os.Bundle;
import android.os.RemoteException;
import android.util.Log;

public class ActivityMonitor extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        try {
            ActivityManagerNative.getDefault().registerActivityWatcher(mActivityWatcher);
        } catch (RemoteException e) {
        }
    }

    private IActivityWatcher.Stub mActivityWatcher = new IActivityWatcher.Stub() {
        public void activityResuming(int activityId) throws RemoteException {
            Log.e("zouyu", "In ActivityMonitor, an Activity resuming: " + activityId);
        }

        public void closingSystemDialogs(String reason) {
            Log.e("zouyu", "In ActivityMonitor, an Activity closing: " + reason);
        }
    };
}
