Variants not working in Android

[#1]

I have register the app to optimizely and create an experiment.

The variants worked fine in the preview mode. But even if I allocate the traffic 100% to a variant, the app still not infected by the live variable in that variant if not in preview mode.

I've set the app id in the manifest.xml.

Hi Yuheng,

When a user is bucketed into either the original or a variation, that bucket is persistent and will not change. Even if you adjust the traffic allocation, it will not change. Adjusting the traffic allocation will only affect new users who have not been bucketed yet. You may need to delete the app and reinstall to test the variant without Preview Mode. Have you tried that?

Best,
Ted
