Related to #25 (updates for React Native 0.60)

P.S. I think the underlying cause is using importing AppCompatCheckBox from android.support.v7.widget, which seems to be not included by default when using React Native 0.60. Any help with a simple, clean workaround solution to get a sample widget working on recent versions of React Native would be highly appreciated. Doesn’t matter so much which widget, no need for consistency with iOS, just to get this working.

The following update seems to solve this issue:

diff --git a/templates/android.js b/templates/android.js
index c9e0648..f2b235a 100644
--- a/templates/android.js
+++ b/templates/android.js
@@ -179,7 +179,7 @@ public class ${name}Module extends ReactContextBaseJavaModule {

+import androidx.appcompat.widget.AppCompatCheckBox;
 
 import com.facebook.react.uimanager.SimpleViewManager;
 import com.facebook.react.uimanager.ThemedReactContext;

This change should be applied to a generated View project if it is needed for React Native 0.60(+) on Android.

Unfortunately this update would cause a similar failure on React Native pre-0.60. I hope we can drop support for RN pre-0.60 someday.
