第一个MapActivity实例是否总是泄漏？

Question

在调查我们的应用程序中的内存问题时,事实证明如果应用程序Activity是MapActivity,它的第一个实例将不会被最终确定.导致其他内存泄漏,例如传递给setContentView的视图.

有没有人注意到之前？

以下是测试代码,显示"MainActivity:1"尚未最终确定,而MainActivity是否继承自Activity.

要进行测试,需要多次更改设备或仿真器方向.

import com.google.android.maps.MapActivity;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

public class MainActivity extends MapActivity {
  private static final String  defaultTag          = "MA";

  private static final boolean isDebugModeActivate = true;
  private static final boolean isClassTagDisplayed = false;
  private static final boolean isWebModeActivate   = false;

  static public void d(Object thiso, String message)
  {
      String tag = defaultTag + (isClassTagDisplayed == true ? "_" + thiso.getClass().getSimpleName() : "");
      message = (isClassTagDisplayed == false ? thiso.getClass().getSimpleName() + " : " : "") + message;
      Log.d(tag, message);
  }

  public MainActivity()
  {
    counter++;
    uid++;
    id = uid;
    d(this, id + " tst constructor (" + counter + ")");
  }
  private static int counter = 0;
  private static int uid = 0;
  private final int id;

  protected void finalize() throws Throwable
  {
    counter--;
    d(this, id + " tst finalize (" +counter + ") ");
    super.finalize();
  }

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

    @Override
    protected boolean isRouteDisplayed()
    {
      return false;
    }
}
