Blur the background in Android

Prerequisites

• A working Android quickstart
• Background effects enabled for the project

Enable blur

NosmaiBackgroundSegmentationConfig config =
    new NosmaiBackgroundSegmentationConfig(
        NosmaiBackgroundSegmentationConfig.Mode.BLUR
    );
config.blurStrength = 55.0f;

NosmaiEffects.setBackgroundSegmentation(config);

blurStrength uses 0 through 100. Update the configuration from the main thread when a slider changes.

Disable blur

NosmaiEffects.clearBackgroundSegmentation();

Verify it worked

The subject should remain visible and sharp while the scene behind it is blurred.
