Aspectj替代这个

Question

我是Aspectj的新手。我的问题是我想在Android中获取我的MainApp的Activity（或Context）而不修改我的原始代码。我有这个：

public class SensorTestActivity extends Activity implements SensorEventListener {
  private SensorManager sensorManager;
  private boolean color = false;
  private View view;
  private long lastUpdate;
 //public static Context context;


/** Called when the activity is first created. */

  @Override
  public void onCreate(Bundle savedInstanceState) {
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN);

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sensor_test);
    view = findViewById(R.id.textView);
    view.setBackgroundColor(Color.GREEN);

    sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
    lastUpdate = System.currentTimeMillis();
    //context=this;
  }

现在使用Aspectj，我想要做的是添加两个注释行并获取Context并使用它。类似的东西：

public aspect Trace extends Application{

    private static Context SensorTestActivity.mContext;

    pointcut inicio(Bundle bundle) : execution(* ..onCreate*(..)) && args(bundle);
    void around(Bundle bundle): inicio(bundle){
        //System.out.println("I'm  in onCreate");
        SensorTestActivity.mContext= this;
        proceed(bundle);

    }

问题是我不能使用“这个”。如果你知道如何做到这一点，或者如果有另一种方法在.aj文件中获取Context，我将非常感激。谢谢！
