我開始使用泄漏金絲雀,我得到這個內存泄漏後旋轉片段與MapView上。爲什麼會發生這種內存泄漏 - android - LeakCanary

這是怎麼了我加入片段活動(我的活動,並在導航菜單中選擇項目後,調用此在的onCreate)使用簡單的片段不被破壞,但只包括地圖片段原則 - 我不要有照顧有關國家保持:

public void changeFragment(String toFragment, Bundle args){ 
    Log.d(TAG, "changeFragment"); 
    Util.hideSoftKeyboard(this); 
    Fragment fragment = null; 
    String backStateName = toFragment; 

    Fragment mCurrentFragment = getFragmentManager().findFragmentById(R.id 
      .fragment_place); 

    if(mCurrentFragment == null){ 
     fragment = instantiateFragment(toFragment,args); 
     getFragmentManager().beginTransaction() 
       .setCustomAnimations(
         R.animator.fragment_slide_in, R.animator.fragment_slide_out, 0, 0) 
       .add(R.id.fragment_place, fragment, backStateName) 
       .addToBackStack(backStateName) 
       .commit(); 
     return; 
    } 

    if(mCurrentFragment.getClass().getName().equals(toFragment)){ 
     return; 
    } 

    boolean fragmentPopped = getFragmentManager().popBackStackImmediate(backStateName, 0); 

    if (!fragmentPopped && getFragmentManager().findFragmentByTag(backStateName) == null){ //fragment not in back stack, create it. 
     fragment = instantiateFragment(toFragment,args); 
     getFragmentManager().beginTransaction() 
       .setCustomAnimations(
         R.animator.fragment_slide_in, R.animator.fragment_slide_out, 0, 0) 
       .add(R.id.fragment_place, fragment, backStateName) 
       .addToBackStack(backStateName) 
       .commit(); 
    } 
}

任何想法,爲什麼是內存泄漏發生的呢?
