Custom SearchView crash on Release build

Question

I'm getting a crash when trying to get a reference to a Custom SearchView class in onCreateOptionsMenu. Normally this works fine but when loading the release apk, it crashes. I tried adding these lines to my proguard but its still crashing:

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

Here is the code:

@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);
    }

Here is the log

Try using the apk profiler in Android Studio 3 to see if your custom class is where you expect it to be and hasn't been obfuscated to a different name — Kuffs, Oct 06 '17 at 12:19

@Zoe absolutely not a duplicate of What is a NullPointerException, and how do I fix it?... as that question encompasses way too broad a category — Mike6679, Oct 06 '17 at 12:22
@Mike6679 your error seems to be related to your proguard config are you sure you have the class in the same package — JAAD, Oct 06 '17 at 12:24
@ColdFire my custom SearchView is definitely in com.mine.mobile.mypackage.usercontrol — Mike6679, Oct 06 '17 at 12:26
anyone? no suggestions? I'm trying variations in proguard to no avail — Mike6679, Oct 06 '17 at 13:07
Are you sure it's not too early to call the service there? https://stackoverflow.com/questions/14451407/nullpointerexception-when-calling-getsystemservicecontext-location-service-and — Endre Börcsök, Oct 06 '17 at 13:12

I was on the right track but apparently my pro guard syntax was incorrect (I used google's example here:). This worked though:

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