意图无法在活动之间切换 - Android 4.0

这是一个奇怪的问题，我的意图是不能在Android 4.0+设备的情况下切换活动，但是，在Android 2.2 / 2.3的设备上，它工作正常。

这就是我为我的类PhotoActivity定义意图的方法。

public static final void startActivityForResult(Activity parent, int requestCode, String userName, String photoUrl, Bitmap preview, boolean isMugshot) {
    System.out.println("photoactivity started" +requestCode+"second"+parent);
    Intent intent = new Intent(parent, PhotoActivity.class)
    .putExtra(USERNAME, userName)
    .putExtra(PHOTOURL, photoUrl)
    .putExtra(PREVIEW, preview)
    .putExtra(IS_MUGSHOT, isMugshot);
    parent.startActivityForResult(intent, requestCode);
}

我想根据特定的用户触摸响应从另一个类切换到上面的活动类。我将其定义如下

case R.id.ImgAvatar:
        PhotoActivity.startActivityForResult(this, REQUEST_SHOW_AVATOR, mUserName, avatarUrl, mAvatar, true);
        break;

我的代码很好，因为在android 2.3 / 2.2的情况下，我可以在行为之间切换。但是，在使用带有android 4.0+的设备时，我不会在触摸响应之间切换活动，而是恢复到我的主要活动（无知为什么）。

我还注意到2.2和4.0版本的控制台输出不同。我仍然无法猜到为什么android 4.0会造成麻烦。

这是活动正常启动时的日志（android 2.2 / 2.3），

这是android 4.0 +

显然，在android 4.0+的情况下，我的第二个活动没有被调用，我被恢复为主要活动。另一个有趣的观察是实际调用了intent，即我达到了我定义intent的函数，但似乎intent无法启动活动，因此intent会运行但它无法启动新活动。我很无能，因为我的代码没有给出任何运行/编译时错误，因此很难找出问题所在。感谢帮助。
