signal-strength-view's Issues

Exception in layout editor

When I try to use this component I always get this message in layout editor:

The following classes could not be instantiated:
- eo.view.signalstrength.SignalStrengthView (Open Class, Show Exception, Clear Cache)
Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE. If this is an unexpected error you can also try to build the project, then manually refresh the layout.

This's the exception I got:

this's the xml code:

<eo.view.signalstrength.SignalStrengthView android:id="@+id/gcs_signal_level" android:layout_width="50dp" android:layout_height="50dp" app:layout_constraintEnd_toStartOf="@+id/gcs_battery_level" app:layout_constraintTop_toTopOf="parent" app:signalStrengthColor="?colorAccent" app:signalStrengthLevel="50" app:signalStrengthTheme="rounded" />

BTW I'm using battery-meter-view in the same project and it works fine.
The sample application is working.
