Service killed if main activity cleaned up on Android

[jasongrishkoff]

Hey so, if my main React Native application is cleared up by Android for memory, the service also stops. This kinda sucks because it means if they're listening to a song, it ends mid-way. I've tried as much as I can to lower the memory footprint of my app, but if I'm doing heavy browsing on multiple apps in the foreground, Android cleans it up.

Any idea how to tweak the code to keep the RNAudioStreamer service alive and avoid Android from killing it when it clears up memory from the main activity? I've been looking into:

1. startForeground
2. START_STICKY or START_REDELIVER_INTENT

Both might be helpful, but not sure where I'd throw those into the code...

Hi @jasongrishkoff
We're seeing similar things on our app.
Did you find a solution to this?

[jasongrishkoff]

Hey @anderslemke, we've been working on a new project over here: https://github.com/Guichaguri/react-native-track-player/ (in the dev branch).

It's much more functional!

Hi @jasongrishkoff
Thanks!
I will check it out.
