While updating to dev06 and ran the app I got the following error:
java.lang.NoSuchMethodError: No static method setContent(Landroid/app/Activity;Lkotlin/jvm/functions/Function0;)Landroidx/compose/Composition; in class Landroidx/ui/core/WrapperKt; or its super classes (declaration of 'androidx.ui.core.WrapperKt' appears in /data/app/tt.reducto.composesample-BYNjMDWbVhiprnPCNJw0LA==/base.apk)
If you're coming from dev05, dev04 (or less), there's a migration needed.
UPDATE: This logic works up to Dev09. BETA Release is currently available.
I manage to make it work. You need to do the following:

Once you get all that done, run your code and you'd be good to go.
For Kotlin DSL
kotlinOptions {

buildFeatures {

}
composeOptions {

}
Make sure to set compose true inside your gradle file..
for build.gradle.kts
buildFeatures {
compose = true
}
for traditional build.gradle
buildFeatures {
compose true
}
In you apps build.gradle app
buildFeatures {
compose true
}
composeOptions {
kotlinCompilerExtensionVersion compose_version
kotlinCompilerVersion kotlin_compiler_verion
}
I had the same error with unnecessary dependency in buildSrc/build.gradle.kts
dependencies {
implementation("com.android.tools.build:gradle:7.0.0-beta02")
}
After removing this the error is gone.
compose version 1.0.0-beta07
I got the same error while used Compose dev07. I fixed the issue by giving the below code in build.gradle (app level):
composeOptions {
kotlinCompilerExtensionVersion = "0.1.0-dev07"
}
For more info please check here
For Kotlin DSL(build.gradle.kts):
android {

I create an project based the wizard Empty Compose Activity of Android Studio Chipmunk | 2021.2.1 Patch 1. It can be compiled, and it works well.
I get the following running error after I upgrade compose_version from compose_version = '1.1.0-beta01' to 1.2.1.
Could not resolve all files for configuration ':app:kotlin-extension'.
> Could not find androidx.compose.compiler:compiler:1.2.1.
Searched in the following locations:

But the app can run well when I remove kotlinCompilerExtensionVersion compose_version in build.gradle (Module), why?

The problem is that there is no Compose Compiler 1.2.1 version. Currently, Compose Compiler follows a different release schedule than other Compose libraries.
Here is the compatibility map and the available versions of Compose Compiler to use together with Kotlin.
In case you're wondering about using different versions between Compose Compiler and the other Compose libraries, it's totally ok to do that, and that's what you should do to have access to the latest versions of them.
You can configure your gradle as follows:
Project module
buildscript {
ext {
kotlinVer = '1.7.10'
composeCompilerVer = '1.3.1' // should be compatible with kotlin version
composeVer = '1.2.1'
}
}
plugins {
id 'com.android.application' version '7.2.2' apply false
id 'com.android.library' version '7.2.2' apply false
id 'org.jetbrains.kotlin.android' version "$kotlinVer" apply false
// ...
}
App module
// ...
android {
// ...
composeOptions {
kotlinCompilerExtensionVersion composeCompilerVer
}
// ...
}
dependencies {
implementation "androidx.compose.ui:ui:$composeVer"
implementation "androidx.compose.ui:ui-tooling-preview:$composeVer"
// ...
}
The version androidx.compose.compiler:compiler:1.2.1 doesn't exist.
You can check it in the google maven repo
You can in any case use the stable version of the module compiler 1.3.0 and all the other compose dependencies at 1.2.1:
buildscript {
ext {
compose_compiler = '1.3.0'
compose_version = '1.2.1'
}
//...
}
and then:
composeOptions {
kotlinCompilerExtensionVersion compose_compiler
}
dependencies {
// stable 1.2.1 releases
implementation "androidx.compose.material:material:$compose_version"
//...
}
As described in the documentation the compiler 1.3.0 requires kotlin 1.7.10:

You can check it in the google maven repo

}
As described in the documentation the compiler 1.3.x requires kotlin 1.7.10:
I am new to Android development and making simple app using Jetpack Compose thesedays.
When I import a library in an empty Jetpack Compose project, the compiler can't find the package path.
import me.aflak.arduino.Arduino
import me.aflak.arduino.ArduinoListener
Error message: Unresolved reference: me
This library works fine for "normal View" project. I already googled but couldn't find a clear answer for it.
I doulble checked that I didn't change any settings but for library include.
I really want to know why it fails to import.
Thanks

I am trying to implement databinding in recyclerview using kotlin. But it is giving me runtime error
Execution failed for task ':app:kaptDebugKotlin'.
A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution
java.lang.reflect.InvocationTargetException (no error message)
Anyone has faced the same error? I have searched and gone through many links related to this error but all states the use of room library which I am not using and still getting this error.
Any help is much appreicated.
Thanks
Instead of
buildFeatures {
dataBinding = true
}
Try this
buildFeatures {
dataBinding true //<--- for binding the data
viewBinding true //<-- for binding the view
}
I solved this error after updating my

Using Kotlin version 1.4.10 instead of 1.4.20 solved my problem.
Try to update Compose version to 0.1.0-dev16. Looks like 0.1.0-dev13 isn't compatible with Kotlin 1.4-rc
