Upgrading Android Studio
Had to upgrade my Android Studio, as it was a nightmare to configure old Chipmunk version to function with newly required AGP plugin.
Upgrade itself
What I had was a manually installed Android Studio Chipmunk, 2021.2.1 on Ubuntu 20.04.4 LTS. By manually installed I mean an installation from android-studio-2021.2.1.14-linux.tar.gz tarball.
Took Help-Check for Updates … per the old habit, it suggested to download new Electric Eel version.
Which I did. Had android-studio-2022.1.1.21-linux.tar.gz now.
When installing it, manually again, it turned out as if it would had been a a fresh new installation. I got worried what happens to all that stuff I have configured in Chipmunk along the road.
Googled a bit. After reading some pretty confusing pages, e.g about selecting channels for upgrade, which seemingly no longer exist, ended up on using the Toolbox app as suggested by Chipmunk Settings-Appeareance & Behaviour -Updates. It is available at www.jetbrains.com/toolbox-app
Manually installed jetbrains-toolbox-1.27.3.14493.tar.gz tarball and ran jetbrains-toolbox
It was straight forward job. Now I have Android Studio Electric Eel, 2022.1.1 Patch 2.
Toolbox is pretty effective, it also handles updates for related products, such as plugins and sdks:
Upgraded emulator and platform tools as well:
Complications after upgrade
LiveData Transformations unresolved
Created a new project with Tabbed Activity template on Electric Eel. It did not compile correctly, left androidx.lifecycle.Transformations.map() as unresolved.
Had an earlier project generated with Chipmunk from Tabbed Activity template as well. It works fine even now. Some dependency changes must have taken place, couldn’t identify the source though.
Instead, after a bit of chatGPT and Googling, turned out Transformations seems to be outdated in newer contexts, one should use methods available in LiveData instead.
Changed the code to use map method of LiveData class itself
val text: LiveData<String> = _index.map
instead of Transformations.map(_index) method
val text: LiveData<String> = Transformations.map(_index)
Goes for other methods in Transformations as well, like switchMap. Spirit of the game nowadays is to use methods available in LiveData instead.
Imports were changed also to:
import androidx.lifecycle.*
//import androidx.lifecycle.Transformations
from
import androidx.lifecycle.LiveData
import androidx.lifecycle.MutableLiveData
import androidx.lifecycle.Transformations
import androidx.lifecycle.ViewModel
Duplicate class kotlincollections
In one of my older projects, created under chipmunk, some dependencies were highlighted due to a newer version being available. Changed all those to newer version indicated by hovering over the highlight. Unfortunately App didn’t build after that, gave instead countless messages like the one below:
Duplicate class kotlin.collections.jdk8.CollectionsJDK8Kt found in modules jetified-kotlin-stdlib-1.8.0 (org.jetbrains.kotlin:kotlin-stdlib:1.8.0) and jetified-kotlin-stdlib-jdk8-1.6.0 (org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.6.0)
Had to switch AGP plugin from 1.7.10 to 1.8.0 in project level build.gradle:
plugins {
id 'com.android.application' version '7.4.2' apply false
id 'com.android.library' version '7.4.2' apply false
//id 'org.jetbrains.kotlin.android' version '1.7.10' apply false
id 'org.jetbrains.kotlin.android' version '1.8.0' apply false
}
