[Q] hacking my way into sniffing intents between apps
I'm experimenting to write a personal app to help me get to know more songs. I want to catch the spotify intent that indicates when the track changes and use the data on my app.
I have been investigating how to do it and tried multiple lines of code like this (iF.addAction("com.android.music.metachanged"); ), but no luck yet. Everybody (stackoverflow) says there is no way to get that info. But the fact is that there is one app that is able to catch that info: musiXmatch. It is able to detect when the track on the spotify free radio changes and deliver the corresponding lyric.
So, I tried decompiling both the musicXmatch and spotify apks using apktool but wasn't able to find the way the apps comunicate with one another. I have yet to get deeper on smali but by what I see this far, the answer isn't there.
So, the next thing I was thinking I'd try was to make an AOSP rom with some extra logging habilities so that i can listen to the communication between the apps (namely, the broadcastreceiver).
My question: żIs there such an aosp distro? One that has extra sniffing/logging capabilities. Also, Anyone has an extra idea on how to accomplish my goal, or maybe some reason for which it will be impossible for me to do it (like for example the intent from spotify being explicit).
Thank you very much in advance for your time.
