What is the best web development IDE on Android ?

Question

Days ago i was writing a code for 2-3 hours on sololearn code playground when suddenly the app hanged and the screen turned out black , it needed to be closed and reopened , After that the whole code got vanished and i got to restart
Because Sololearn doesn't save the code on the local storage andyou need to save it manually online
Same problem happens when i'm spending too much time at the code playground or when i'm typing more than 100 lines

That's why i want a good and efficient IDE
Which simply has the following features :
- offline compiler
- has the ability to store and manage files
- supports easy access to libraries and frameworks
- and most important , does not hang !
And that's all

I already tried Dcoder and it's really incredible but it has one tiny issue , it works only online
There are lots of IDE'S for web on play store
And i don't wanna spend time trying each one of them so please inform me about your experience in this very topic
