## Java Intellisense
|
||||
Support for Java Intellisense is currently in beta, so any **feedback is appreciated**.
|
||||
|
||||
To use Java intellisense, make sure the option is enabled in Settings (Extensions > Android > Enable Java language support for Android)
|
||||
and press `ctrl/cmd-space` when editing a Java source file.
|
||||
|
||||
You can read more about using code-completion on the [VSCode website](https://code.visualstudio.com/docs/editor/intellisense) and how to configure code-completion to suit your Android project in the [wiki](https://github.com/adelphes/android-dev-ext/wiki).

## Expression evaluation

Format specifiers can be appended to watch and repl expressions to change how the evaluated result is displayed.
