How do I differentiate from which store app is ins

问题:

My app. is deployed in Play Store as well as Baidu Store. For notificatiions, need to differentiate from where app. is installed.

When I used getInstallerPackageName() method, Redmi Note 3 returns correct value but HTC returns null.

Why is this difference observed ?

Is there any other better way ?
