Is there any way to intercept or run a callback before user open any app on their device?

For instance, I need a feature when user opens an app, my app will wake up first, intercept the intent (Android) in broadcast recevier, then do something inside our application. At the end, I will call startActivity(intent) to open the app that user supposes to open at first.

No, there isn't. That would be a security nightmare, you're basically asking for a malware maker's dream API. If its your own personal device you could build a custom version of AOSP which does that, but that would be the only way.
