Утечка Huawei MapView во фрагменте

Рекомендуется использовать MapFragment (расширяет собственный компонент Fragment Android и может использоваться для добавления карты в приложение самым простым способом) или SupportMapFragment вместо используя свой фрагмент для встраивания Huawei MapView.

Обновление: проверьте следующие коды:

public class App extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        if (LeakCanary.isInAnalyzerProcess(this)) {//1
            // This process is dedicated to LeakCanary for heap analysis.
            // You should not init your app in this process.
            return;
        }
        LeakCanary.install(this);
    }

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
    }
}

Проблема может заключаться в том, что карта продолжает проверять местоположение после уничтожения. Попробуйте вставить hMap?.setMyLocationEnabled(false); в onDestroy(), чтобы он больше не отслеживал местоположение после уничтожения.
