Ratings and reviews

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!

JStudio is a solid app with many useful development features. However, release builds are not supported properly. I can only build debug APKs. Release builds work in Android Studio, but fail in JStudio, including when using Gradle via terminal. Please add proper support for assembling release APK/AAB with signing configs. Fixing this would greatly improve the app.

What's new
