和

import android.app.Activity;
import android.app.ActivityManager;
import android.os.Bundle;
import android.util.Log;

public class LogViewActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ActivityManager activityManager = (ActivityManager) getApplication()
            .getSystemService(ACTIVITY_SERVICE);
    Log.v("LOG_SERVICE", activityManager.getRunningTasks(1).get(0)
            .toString());
}

}
