An excellent IDE for coding in java. Many great features right on your phone, that you expect from an IDE that runs on PC. Error checking as you type, code completion with links to the relevant javadoc, as well as redo, undo, and my favorite, buttons to move the curser. Unneeded on a PC, its a blessing when writing code on your phone. I would trade the tab button for one that performs a right-click though.

I am just learning Java. It seemed promising for doing homework in a portable device, but I can change my code all that I want, save it, but the code never seems to recompile, as it gives me the same result every single time. Plus, the terminal gives me a spinning circle in the upper left that never goes away, and you can't use a Bluetooth mouse to change tabs; you can only use the touch screen. Plus some UI elements could be smaller to save screen space. If these get fixed it will be great!

I love your app and use it regularly for Java coding on mobile. However, I’ve noticed that the keyboard’s quick access toolbar (Gboard’s top row with emoji, clipboard, settings, etc.) gets hidden in the coding editor. This makes it hard to use shortcuts or paste code easily. It would be amazing if you could support this toolbar or provide an option to toggle it in the editor. Thanks for your hard work!
