發佈版本上的自定義SearchView崩潰

Question

嘗試獲取對onCreateOptionsMenu中的自定義SearchView類的引用時發生崩潰。通常這工作正常，但加載釋放apk時，它崩潰。我想這些行添加到我的proguard的，但它仍然崩潰：

# Android support 
-keep public class com.mine.mobile.mypackage.usercontrol.SearchViewCustom 
-keep class android.support.v7.** { *; } 
-keep interface android.support.v7.** { *; } 

這裏是代碼：

@Override 
    public boolean onCreateOptionsMenu(Menu menu) { 

     mMenu = menu; 
     getMenuInflater().inflate(R.menu.menu_invest, menu); 
     final MenuItem searchItem = menu.findItem(R.id.action_invest_search); 

     if (searchItem != null) { 
      mSearchView = (SearchViewCustom) MenuItemCompat.getActionView(searchItem); 

      SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); 
      mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); 
     } 

     mPresenter = new BaseActivityPresenterImpl(this,mSearchView,mMenu,searchItem); 
     mPresenter.setupActionBar(NONE,false); 

     return super.onCreateOptionsMenu(menu); 
    } 

這裏是日誌

menu.xml文件

<?xml version="1.0" encoding="utf-8"?> 
<menu xmlns:android="http://schemas.android.com/apk/res/android"

     app:actionViewClass="com.mine.mobile.mypackage.usercontrol.SearchViewCustom" 
     app:showAsAction="always|collapseActionView" /> 
</menu> 

這不是重複什麼是什麼是NullPointerException，以及如何解決它？ ...這個問題包含的方式太廣泛

我在正確的軌道上，但顯然我的職業警衛語法不正確（我使用谷歌的例子here:）。這雖然工作：

-keep public class com.mine.mobile.mypackage.usercontrol.SearchViewCustom { 
    public *; 
}
