android – 构建apk后的错误

生成签名的apk后,操作栏视图(共享操作提供程序和searchview)崩溃.当我从 Android工作室调试应用程序时它正在工作,但当我生成签名的apk并安装应用程序到设备我得到这样的错误：

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.widget.SearchView.setQueryHint(java.lang.CharSequence)' on a null object reference

要么

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.widget.ah.a(android.content.Intent)' on a null object reference

我正在使用支持库和工具栏的最新版本. (通过设置setSupportActionBar(mToolbar)).

SearchView xml：

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ertir="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/action_search"
        android:title="@string/title_activity_search"
        ertir:showAsAction="always"
        ertir:actionViewClass="android.support.v7.widget.SearchView" />
</menu>

Java的

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.search,menu);
        MenuItem searchItem = menu.findItem(R.id.action_search);
        mSearchView = (SearchView) searchItem.getActionView();
        mSearchView.setQueryHint(getString(R.string.search_hint));
        mSearchView.setFocusable(true);
        mSearchView.setIconified(false);
        mSearchView.requestFocusFromTouch();
        mSearchView.setonQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                mSearchView.clearFocus(); //Hide keyboard
                search(query,searchTypeArray.get(searchTypeSpinner.getSelectedItemPosition()).getType());
                return false;
            }

            @Override
            public boolean onQueryTextChange(String query) {
                if (searchTypeArray.get(searchTypeSpinner.getSelectedItemPosition()).getType().equals("blogs"))
                    searchAfter(1100,query,searchTypeArray.get(searchTypeSpinner.getSelectedItemPosition()).getType());
                else
                    search(query,searchTypeArray.get(searchTypeSpinner.getSelectedItemPosition()).getType());
                return false;
            }
        });
        return true;
    }

我怎样才能解决这个问题？如上所述,我只有在签署apk后才会收到错误.
