RoboVM and AndroidStudio 4.1

Dealing with Android Studio always tricky, v4.1 brings another set of issues to solve.

Installing the plugin

2.3.10 is available in JetBrains marketplace and can be installed directly from plugin settings dialog. But due wrong configuration it is not visible in Android studio. There are few options for Android studio:

Install manually

Download .zip file from MobiVM site and use Install Pluging From Disk... option.
Important: Safari will automatically unpack .zip file, it should be downloaded without unpacking and installed as .zip!

Install from custom plugin repository

These custom repositories point to files located at MobiVM site.
In settings dialog:

• select Manage Plugin Repositories;
• add https://dkimitsa.github.io/assets/mobivm-release.xml for installing the latest release;
• or add https://dkimitsa.github.io/assets/mobivm-snapshot.xml for installing the latest snapshot;

Then switch to Market place search for MobiVM;

Not working RoboVM/New Project(Module) menu

Android Studio doesn’t have new Project/Module menu option and RoboVM delivers workaround. In AS 4.1 it stopped working.
Failure caused by exception in kotlin-plugin v1.4:

com.intellij.openapi.extensions.ExtensionInstantiationException: java.lang.ClassNotFoundException: org.jetbrains.kotlin.tools.projectWizard.wizard.NewProjectWizardModuleBuilder PluginClassLoader[org.jetbrains.kotlin, 1.4.10-release-Studio4.1-1] com.intellij.ide.plugins.cl.PluginClassLoader@64d3a9e5 [Plugin org.jetbrains.kotlin]
    at com.intellij.openapi.extensions.AbstractExtensionPointBean.findExtensionClass(AbstractExtensionPointBean.java:51)
    at com.intellij.openapi.extensions.AbstractExtensionPointBean.instantiateClass(AbstractExtensionPointBean.java:92)
    at com.intellij.ide.util.projectWizard.ModuleBuilderFactory.createBuilder(ModuleBuilderFactory.java:31)

Root case – bug in kotlin-plugin bundled with AS 4.1:

• NewProjectWizardModuleBuilder was moved to standalone .jar that is not deployed with AS anymore;
• But this class is still registered with extensions/ide.xml.

Issue was reported to Jetbrains: KT-42779.

Workaround: remove registration from the plugin, simple script that unpacks-fixes-packs back:

unzip ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins/Kotlin/lib/kotlin-plugin.jar META-INF/extensions/ide.xml -d unpack
cat unpack/META-INF/extensions/ide.xml | sed 's|<moduleBuilder builderClass="org.jetbrains.kotlin.tools.projectWizard.wizard.NewProjectWizardModuleBuilder"/>||g' > unpack/META-INF/extensions/ide.xml.2
mv unpack/META-INF/extensions/ide.xml.2 unpack/META-INF/extensions/ide.xml
cd unpack; zip -r ~/Library/Application\ Support/Google/AndroidStudio4.1/plugins/Kotlin/lib/kotlin-plugin.jar *

Tutorial: adding iOS module to Android app

Not a bug but been often asked:

1. Add new module using menu: RoboVM -> New -> New Module...;
2. Module type: RoboVM -> RoboVM iOS App without storyboard;
3. Make sure that Content root and Module file location set to differt from Android module location (and will not override it) – e.g. ios;

After this gradle sync will fails with message:

Project directory ‘ios’ is not part of the build defined by settings file ‘settings.gradle’ If this is an unrelated build, it must have its own settings file.

Add it to settings.gradle as described in Gradle guide:

include ‘:app’, ‘:ios’

Next sync will fail with the message:

Task ‘wrapper’ not found in project ‘:ios’.

Adding the task to ios/build.gradle to fix:

task wrapper(type: Wrapper) {
    distributionType = Wrapper.DistributionType.ALL
}

Next sync will fail with the message:

Task ‘prepareKotlinBuildScriptModel’ not found in project ‘:ios’.

Root case of it – bug in Gradle Plugin 4.1.0 and Gradle 6.5.
Workaround is possible as described in issue above with reverting to working versions: Update build.gradle with 4.0.1:

dependencies {
        classpath "com.android.tools.build:gradle:4.0.1"
}

Update gradle/wrapper/gradle-wrapper.properties with 6.1.1:

distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip

Hooray! Sync is successful, ios module can be built and running!
