Getting started

If you want to use different folder, please read Configuration section.

PixelPerfect.hide();

Configuration

PixelPerfect.Config provides possibility to configure major attributes of PixelPerfect. This snippet demonstrates usage of custom overlayImagesAssetsPath (assets folder for overlay images) and overlayActiveImageName (name of active by default overlay image):

PixelPerfect.Config config = new PixelPerfect.Config.Builder()
.overlayImagesAssetsPath("my_overlays")
.overlayActiveImageName("main.png")
.build();
PixelPerfect.show(HomeActivity.this, config);

Permissions and Android Marshmallow+

PixelPerfect requires SYSTEM_ALERT_WINDOW permission to run properly. So, for Marshmallow and later versions you have to handle permissions with PixelPerfect.hasPermission(context) and PixelPerfect.askForPermission(context) methods.

You can find demonstartion of its usage in Sample app.
