# agent-koog
2+
3+
This is a Kotlin Multiplatform project targeting Android.
4+
5+
- [/composeApp](./composeApp/src) is for code that will be shared across your Compose Multiplatform applications.
6+
It contains several subfolders:
7+
8+
- [commonMain](./composeApp/src/commonMain/kotlin) is for code that’s common for all targets.
9+
- Other folders are for Kotlin code that will be compiled for only the platform indicated in the folder name.
10+
For example, if you want to use Apple’s CoreCrypto for the iOS part of your Kotlin app,
11+
the [iosMain](./composeApp/src/iosMain/kotlin) folder would be the right place for such calls.
12+
Similarly, if you want to edit the Desktop (JVM) specific part, the [jvmMain](./composeApp/src/jvmMain/kotlin)
13+
folder is the appropriate location.
14+
15+
## Build and Run Android Application
16+
17+
To build and run the development version of the Android app, use the run configuration from the run widget
18+
in your IDE’s toolbar or build it directly from the terminal:
19+
20+
- on macOS/Linux
21+
22+
```shell
23+
./gradlew :composeApp:assembleDebug
24+
```
25+
26+
- on Windows
27+
28+
```shell
29+
.\gradlew.bat :composeApp:assembleDebug
30+
```
31+
32+
